6.2 Hydraulic Seeding

6.2a Hydraulic Seeding: Definition

Hydraulic seeding methods shall be defined to include the distribution of seed through a pump under pressure with equipment that continuously agitates the seed in a suspension of water. In addition to seed and water, the hydraulic seeding suspension may also include pulverized limestone and/or pelletized limestone and/or fertilizer and/or hydraulic mulch. Hydraulic mulch products shall contain wood fiber, wood cellulose fiber (paper fiber, derived from new or recycled paper products), or a combination of wood fiber and wood cellulose fiber (wood fiber + wood cellulose fiber hydraulic mulch). When fertilizer and/or limestone is included in the hydraulic seeding suspension with seed, the maximum combined weight of fertilizer and limestone included in the hydraulic seeding suspension shall not exceed 150 pounds per 100 gallons of water. See Section 4 for additional information regarding fertilizer and limestone materials and application methods.

6.2b Hydraulic Seeding: Fertilizer Materials and Starter Fertilizer

.1. Requirements. The addition of nitrogen (N), phosphorus (P or P2O5 ), and potassium (K or K2O), to the seeding site shall be in accordance with soil test results and the recommendations of the U.M. Soil Testing Laboratory, or other soil test lab, as specified in Section 1 and Section 2.

.2. Fertilizer application. Fertilizer may be applied up to 10 days before seeding or at the time of seeding with drop spreaders, rotary spreaders, or with hydraulic seeding equipment. When hydraulic seeding equipment is used to apply fertilizer and seed in a single operation (i.e., fertilizer and seed are suspended together in the hydraulic seeding mix), the specifications of Section 6.2c shall apply.

.3. Starter fertilizer. In the absence of soil tests, and without regard to any established nutrient requirements or soil deficiencies, starter fertilizer may be distributed by drop or rotary spreaders, or included in the hydraulic seeding suspension, so that not more than 1.0 pound of nitrogen (N) per 1000 ft2 (45 pounds N per acre), and 2.0 pounds of phosphorus (P2O5) per 1000 ft2 (90 pounds P2O5 per acre), and 2.0 pounds of potassium (K2O) per 1000 ft2 (90 pounds K2O per acre) is applied up to 10 days before seeding or at the time of seeding.

6.2c Hydraulic Seeding: Fertilizer Application to Correct Soil Nutrient Deficiencies

.1. Requirements. When nitrogen and/or phosphorus and/or potassium fertilizer is applied with seed in the hydraulic seeding suspension in amounts which exceed the specifications for starter fertilizer in Section 6.2a.3., above, the addition of these nutrients to the hydraulic seeding suspension shall be in accordance with soil test results and the recommendations of the U.M. Soil Testing Laboratory, or other soil test lab, as specified in Section 1 and Section 2.

.2. Limitations. Because seed germination and establishment may be severely reduced by the addition to the hydraulic seeding suspension of the full rates of fertilizer material that may be recommended by soil tests, the actual amount of fertilizer included in the hydraulic seeding suspension shall be limited as follows: When seed is included in the hydraulic seeding suspension, the amount of fertilizer added to the hydraulic seeding suspension shall not exceed 2.0 pound of nitrogen (N) per 1000 ft2 (90 pounds N per acre), and/or 4.0 pounds of phosphorus (P2O5) per 1000 ft2 (180 pounds P2O5 per acre), and/or 4.0 pounds of potassium (K2O) per 1000 ft2 (180 pounds K2O per acre). When soil test results recommend the application of more than 90 lbs. of soluble nitrogen per acre, or more than 180 lbs. of phosphorus per acre, or more than 180 lbs. of potassium per acre, the required amounts of these materials which are in excess of these limits shall be applied with appropriate drop or rotary spreader equipment in one or more separate operations (see Section 4.2).

6.2d Hydraulic Seeding: Limestone Application

.1. Requirements. Limestone applications shall be made in accordance with soil tests performed by the U.M. Soil Testing Laboratory, or other soil test lab, as specified in Section 1, Section 2, and Section 4.

.2. Limestone application using spreaders. When limestone is applied with drop or rotary spreaders, the limestone may be applied at any time before seeding or at the time of seeding. Applications of limestone which exceed 50 lbs. per 1000 ft2 (2,200 lbs. per acre) shall be incorporated into the soil before seeding operations are begun, as specified in Section 4.2; limestone applications which are less than these maximum amounts may be applied at any time before seeding or at the time of seeding.

.3. Limestone included in hydraulic seeding mix. Because seed germination and establishment may be severely reduced by the addition to the hydraulic seeding suspension of the full rates of limestone material that may be recommended by soil tests, the actual amount of limestone included in the hydraulic seeding suspension shall be limited as follows: When limestone is applied with seed in the hydraulic seeding suspension, the amount of limestone included shall not exceed 50 lbs per 1000 ft2 (2,200 lbs. per acre). Pulverized limestone or pelletized limestone shall be the only limestone used for this application: neither granulated limestone, nor burnt lime, nor hydrated lime shall be used for hydraulic seeding.

6.2e Hydraulic Seeding: Seed Application and Distribution

Hydraulic seeding equipment shall be operated according to the directions for operation provided by the manufacturer of the hydraulic seeding equipment. Hydraulic seeding applications shall ensure that all materials which may be included in the hydraulic seeding suspension, including seed, hydraulic mulch, tackifier, mulch binder, dye, fertilizer, and limestone, are added in the required amounts and sequence, and are fully mixed before application. Hydraulic seeding applications shall be made so that the hydraulic seeding suspension falls as a uniform spray onto the soil, and so that minimal areas within the seeding site shall receive significant underapplication or overapplication.

6.3 Conventional Seeding

6.3a Conventional Seeding: Definition

Conventional seeding methods shall be defined to include the use of conventional drop spreaders, broadcast spreaders, and other types of seed spreading equipment that do not disturb the soil surface when they distribute seed. Fertilizer and limestone applications shall be made with appropriately calibrated equipment in one or more separate operations. See Section 4 for additional information about fertilizer and limestone materials and application methods.

6.3b Conventional Seeding: Fertilizer Materials and Starter Fertilizer

.1. Requirements. The addition of nitrogen (N) and/or phosphorus (P or P2O5 ) and/or potassium (K or K2O) to the seeding site shall be in accordance with soil test results and the recommendations of the U.M. Soil Testing Laboratory, or other soil test lab, as specified in Section 1 and Section 2.

When limestone is applied with drop or rotary spreaders, the limestone shall be applied as follows: Applications of limestone which exceed 50 lbs. per 1000 ft2 (2,200 lbs. per acre) shall be incorporated into the soil before seeding operations are begun, as specified in Section 4.2; limestone applications which are less than these maximum amounts may be applied at any time before seeding, at the time of seeding, or up to five (5) days after seeding operations are completed.

6.3d Conventional Seeding: Seed Distribution and Incorporation

The seed distributed by conventional seeding methods shall be uniformly spread in two directions at right angles to each other, using one half of the total seed to be distributed in each direction, unless extreme slopes interfere with the safe or practical use of the seeding equipment, in which case one or more passes in the same direction shall be an acceptable substitute. After the seed is distributed, the seed shall be incorporated into the soil to an average depth of 1/8 to 1/4 inch below the soil surface.

6.3e Conventional Seeding: Soil Rolling

Areas which receive seed by conventional seeding methods shall be rolled with a weighted roller after seeding, so that the seed is pressed firmly into the soil.

6.4 Cultipacker Seeding

6.4a Cultipacker Seeding: Definition

Cultipacker seeding methods shall be defined to include all seed distribution equipment that covers the seed with soil at the time of seeding, including slot seeders and disk seeders. Fertilizer and limestone applications shall be made with appropriately calibrated equipment in one or more separate operations. See Section 4 for additional information regarding fertilizer and limestone materials and application methods.

6.4b Cultipacker Seeding: Fertilizer Materials and Starter Fertilizer

.1. Requirements. The addition of nitrogen (N) and/or phosphorus (P or P2O5 ) and/or potassium (K or K2O), to the seeding site shall be in accordance with soil test results and the recommendations of the U.M. Soil Testing Laboratory, or other soil test lab, as specified in Section 1 and Section 2.

.2. Fertilizer application. Fertilizer may be applied with drop or rotary spreaders up to ten (10) days before seeding, or at the time of seeding, or up to five (5) days after seeding operations are completed.

6.4d Cultipacker Seeding: Seed Distribution and Incorporation

The seed distributed by cultipacker seeding methods shall be uniformly spread in two directions as right angles to each other, using one half of the total seed to be distributed in each direction, unless extreme slopes interfere with the safe or practical use of the seeding equipment, in which case one or more passes in the same direction shall be an acceptable substituted. Cultipacker seeders shall bury the seed which they distribute to an average depth of 1/8 to 1/4 inch below the soil surface, and shall firmly press the seed into the soil.

6.5 Site Protection, Damage Repair, and Reseeding

6.5a Site Protection

It shall be the responsibility of the seeding contractor to install signs, flagging, etc. at the perimeter of seeding sites immediately after the completion of seeding operations, which shall serve to notify foot and vehicular traffic that a sensitive area may be damaged by their entry. The seeding contractor shall not be financially or otherwise held liable to repair a seeding site that is damaged by the entrance of such traffic when the site has been appropriately designated with signs, flagging, etc. at its perimeter (see Disclaimer, Section 6.9).

6.5b Erosion Protection and Damage Repair

.1. General. It shall be the responsibility of the seeding contractor to ensure that seed and other materials applied according to the specifications of Section 6 are not blown, washed, or otherwise removed from the seeding site, and so that nearby streams and other areas shall be protected from soil, fertilizer, compost, etc., and the incursion of unwanted grass seed.

.2. Repairs to seeding sites. In the event of heavy rain, wind, or other natural event that causes damage to the seeding site which is of a kind or that may have been anticipated or prevented by the seeding contractor, such as through the use of mulch, staples, tackifier, etc., then the seeding contractor shall be obliged to make repairs limited to the damaged areas within the seeding site, so that the site is restored to a condition acceptable according to the specifications of Section 3 and Section 6, and which is capable of supporting a cover of turfgrass which would be of a quality and type acceptable according to the specifications of Section 6.

.3. Repairs to nearby areas. In the event of heavy rain, etc. that causes damage to the seeding site, as described in Section 6.5b.2., above, and which also causes damage to nearby areas, as may be evidenced by seed deposition, mulch deposition, soil deposition, etc. on the surfaces of the nearby areas., then the seeding contractor shall be obliged to make repairs to the damaged nearby areas, so that the nearby areas shall be restored to a condition substantially similar to their condition before the damaging event.

.4. Special limitations. The seeding contractor shall not be obliged, financially or otherwise, to regrade, replace lost topsoil, refertilize, reseed, remulch, or make any other repairs to the seeding site, or to any nearby areas, when there is evidence that the damage caused to the seeding site was substantially due to water, soil, or other materials which passed into the seeding site from an area which was not stabilized or under the control or supervision of the seeding contractor. Examples of situations which shall void the responsibility of the seeding contractor to repair the seeding site and nearby areas shall include the failure of responsible parties to provide effective groundcover, spillways, drainage diversions, water settlements, silt fence, etc. for areas which drain into the seeding site, which would have prevented significant damage to the seeding site and nearby areas.

6.6 Clean Up

Grading stakes, stones, trash, and other debris which may hinder future maintenance of the seeding site (Section 6.7) shall be removed from the seeding site when seeding operations are completed. Soil, fertilizer, compost, limestone, and other debris shall be removed from paved areas as soon as possible after seeding operations are completed. Clean up operations shall be completed before acceptance is given.

6.7 Acceptance

6.7a Acceptance of Materials

The seeding contractor shall inform all affected parties of the composition of the fertilizer, compost, limestone, seed mixes, and seed blends which are intended for application at the seeding site before any of these materials are applied at the seeding site; acknowledgment of acceptance of these materials shall be given by the owner, general contractor, landscape architect, or other person(s) authorized to make such a decision before seeding and spreading operations are begun. Labels and other material identification pertaining to the materials which are applied shall be retained by the seeding contractor for a minimum of 90 days after the completion of seeding and spreading operations.

6.7b Acceptance of Performance

Acknowledgment of acceptable performance shall be given by the owner, general contractor, landscape architect, or other person(s) authorized to inspect the seeding site upon the satisfactory completion of each Subsection of Section 6. The seeding site shall be inspected within 24 hours of the completion of each Subsection, or upon the completion of seeding operations, as indicated by the seeding contractor, unless specified otherwise. The seeding contractor shall give notification when all Subsections of Section 6 have been completed; final acceptance and payment shall be made within 24 hours of such notification, or within the time period specified in the contract.

6.8 Post-Seeding Care, General Turfgrass Areas

6.8a Areas Maintained

The specifications of Section 6.8 shall apply only to the post-seeding care of newly seeded general turfgrass areas; the seeding contractor shall not provide post-seeding care for newly seeded rough turfgrass areas except when the terms of the seeding contract specifically mandate such care.

6.8b Maintenance Period

It shall be the responsibility of the seeding contractor to provide written notification and verbal explanation of the provisions of Section 6.8 to the parties responsible for maintaining newly seeded general turfgrass areas (i.e., the owner, general contractor, landscape architect, etc.). If such notification is not given, or if different provisions for the maintenance of the seeded area are not approved, it shall be the responsibility of the seeding contractor to maintain the seeded area for a period of 30 days after seeding operations have been completed, or until the grass plants have grown to a minimum height of 2.0 inches, whichever may come first. However; if seeding operations are completed outside the recommended times for seeding general turfgrass areas (Table D, Section 6.1b), the seeding contractor shall neither be required to maintain the newly seeded areas (Section 6.8b-f), nor guarantee the success of the seeding (Section 6.10), unless specified otherwise.

6.8c Irrigation During Germination

.1. Requirements. The seedbed shall receive natural rainfall or irrigation within 5 days of the completion of seeding operations, so that the soil of the seedbed is moistened to a minimum average depth of 4.0 inches. Natural rainfall shall not be relied upon to provide all the water needs of the germinating seeds, but irrigation water shall be added as needed from time to time to ensure that the soil surface, to a depth of 0.50 inch, shall not dry out to any extent which may allow germinating seedlings to wilt and die. The soil of the seedbed shall be maintained in a moist condition favorable for seed germination until a minimum of 75% of the seed of all species in the seed mixture or seed blend has germinated and grown to a minimum height of 0.50 inch. Because seed germination rates vary among grass species and cultivars, sufficient time shall be allowed for the germination of all the components of the seed mixture or seed blend. As a guide, Perennial Ryegrass requires 5-10 days to germinate, Fescues require 7-14 days to germinate; and Kentucky Bluegrass requires 14-21 days to germinate. When a minimum of 75% of the seed of all species in the seed mixture or seed blend have germinated and grown to a minimum height of 0.50 inch, the specifications of Section 6.8c.1. shall be completed, and performance of the specifications of Section 6.8d shall begin.

.2. Recommendations. To accomplish the requirements of Section 6.8c.1., above, it is recommended that after seeding operations are completed, the seedbed be irrigated with 0.50 to 1.50 inches of water so that the soil is thoroughly moistened to a minimum average depth of 4.0 inches. After this initial moistening, the upper 0.50 inch of soil may usually be maintained at a satisfactory moisture level when approximately 0.10 inch of irrigation water or natural rainfall is added to the soil once per day. However, in sites with sandy soils, or during periods of high temperature and/or low humidity and/or high winds, the seedbed may require irrigation with 0.10 inches of water as often as twice per day to ensure that the seedlings do not wilt and die because of lack of moisture in the seedbed. It is further recommended that only the amount of water needed to maintain the seedbed at the specified moisture levels be applied, and that the application of excess irrigation water, such as may cause runoff or puddling, be avoided.

6.8d Irrigation During Establishment

When a minimum of 75% of the seed of all species in the seed mix or seed blend have germinated and grown to a height of 0.50 inch, the watering schedule shall be modified to allow the soil surface, to a depth of 0.25 inch, to dry between periods of irrigation or rainfall. However, at no time shall the soil of the seedbed be allowed to dry to such an extent that the foliage of the tender seedlings be caused to wilt or die because of lack of water in the seedbed. To accomplish this, it is recommended that during the period of seedling establishment, the seedbed be irrigated deeply every few days with as much as 0.50 inch of water per irrigation or rainfall, so that the soil is kept moist to a minimum average depth of 6.0 inches. When the grass has grown to a height of 2.0 inches, the specifications of Section 6.8d and the period of responsibility of the seeding contractor for the maintenance of the site shall be completed, and performance of the specifications of Section 6.8e shall begin.

6.8e Mowing Young Grass

After the young grass has grown to a minimum height of 3.0 inches, and before it reaches a maximum height of 5.0 inches, it is recommended that it be mowed to a height of 2.0 inches to 3.0 inches. The first mowing should be performed with properly sharpened mower blades at a time when the soil is moist but not wet, and the grass leaves are dry but not wilted or under some other stress. From that time onward, mowing should be performed as needed in a timely manner so that not more than 1/3 of the total leaf area of the grass is removed during any one cutting. It is further recommended that a mowing height of 2.0 to 3.0 inches be maintained, and that the water needs of the young grass be carefully monitored for the next 2 months.

6.8f Fertilizing Young Grass

After the young grass has received its first mowing, it is recommended that it be fertilized with a complete fertilizer, such as 20-20-20, 10-10-10, or 5-10-5, etc., so that not more than 0.5 pounds of nitrogen (N) are applied per 1000 ft2 . This initial (one time) application of fertilizer may be made to young grass when maximum outside temperatures are 85 degrees Fahrenheit or less during the months of September, October, November, March, April, or May, and should only be applied when natural rainfall or irrigation will promptly wash the fertilizer off the leaf blades and into the soil. The contractor shall remove fertilizer from paved areas as soon as possible after fertilizing operations have been completed.

6.8g Acceptance of Performance of Post-Seeding Care

Acknowledgment of acceptable performance for the 30-day term of post-seeding care provided by the seeding contractor for general turfgrass areas shall be given by the owner, general contractor, landscape architect, or other person(s) authorized to inspect the seeding site upon the satisfactory completion of Section 6.8a-f. The seeding site shall be inspected within 24 hours of the completion of the post-seeding care provided under Section 6.8, as indicated by the seeding contractor; final acceptance and payment shall be made within 24 hours of such notification, or within the time period specified in the contract.

6.9 Disclaimer

6.9a Damage

The seeding contractor shall not be financially or otherwise held liable to repair damages incurred to the seeding site as a result of materials not applied under the supervision of the seeding contractor, nor by vandalism, nor by acts of God. The seeding contractor shall not be financially or otherwise held liable to reseed, repair, or otherwise amend the seeding site as a result of the use of seed or other products which are labeled in error or which are otherwise not in accordance with the label or description provided with them by the manufacturer or distributor of the products, when they are applied by the seeding contractor in good faith, in accordance with their label or description.

6.9b Hazards

It shall be recognized that the seeding site is a construction zone not under the ownership or legal control of the seeding contractor, and as such may present hazards to persons or property which enter the site. The seeding contractor specifically disclaims any and all responsibility for the safety and security of persons or property which may enter the seeding site before the seeding contractor has begun work or when work is underway or at any time after work has been completed, and without regard to whether such entry is legal or otherwise. The seeding contractor shall assume no responsibility for personal injury or property damage, nor be subject to any claims of negligence, when the seeding contractor has performed work according to the specifications of MSA-GS-99, as mutually agreed, or has applied products or materials according to the recommendations of their manufacturer or distributor.

6.10 Guarantee

6.10a General Guarantee

The seeding contractor shall guarantee that all seed mixtures or seed blends shall be selected and used under the supervision of the seeding contractor, and that those seed mixtures or seed blends shall be selected and used according to the specifications of Section 5 and Section 6, unless specified otherwise, and shall be appropriate for the site and the intended use of the site. The seeding contractor shall guarantee that all seeding and post-seeding care performed under the supervision of the seeding contractor shall be according to the specifications of Section 6, unless specified otherwise.

6.10b Term and Limitations to Guarantee

.1. Term. When the seeding contractor provides post-seeding care for newly seeded general turfgrass areas, the seeding contractor shall guarantee the success of the new seeding, which shall develop satisfactory groundcover at the end of the 30-day term of post-seeding care, unless specified otherwise.

.2. Limitations. When seeding operations are completed outside the specified seeding times for general turfgrass areas, as specified in Table D in Section 6.1b, because of contractual obligations or because of delays not caused by the seeding contractor, the seeding contractor shall not provide post-seeding care or guarantee the success of the seeding, unless specified otherwise.

.3. Exclusion of rough turfgrass areas. The seeding contractor shall not provide post-seeding care or guarantee the success of any rough turfgrass areas, unless specified otherwise.

6.11 Payment

The seeding contractor shall give notification upon the completion of Section 6; the seeding site shall be inspected within 24 hours of such notification, and payment shall be made at that time, or as specified in the contract. When payment is not received within the specified time period, the seeding contractor may void any guarantees related to Section 6, may discontinue the maintenance of newly seeded areas, and may seek appropriate legal remedies.
