Abstract: The invention provides a new form of vegetative propagating material, referred to as “the grass plantlet”, as well as a method for producing it. The new vegetative planting material and the method by which it is obtained make it possible to replicate and increase both warm and cool season grasses more rapidly than by the conventional methods of seeding, sprigging, or plugging. Three to five new, clean, and pure generations of a newly developed seeded or vegetative cultivar can be obtained each year. Outcrossing, the need for burning and possibly for herbicide use are eliminated by the present invention. The present methodology embodies a sterile production system resulting in grass plantlets that are free of nematodes, pathogenic fungi, and damaging insects.

Abstract: A method for planting and stabilizing soilless sods is taught, beginning with planting pure stock of the desired cultivar in sterile media over plastic sheeting. The pure stock, once it has matured into a sod, it is harvested and milled into vegetative planting material. The milled material is suspended in a liquid slurry in an agitating tank and discharged into a trailing planter assembly that spreads the slurry evenly over unrolling plastic sheeting where it acts not only as planting material but, in sufficient quantities, also as a stabilizing protective mulch that maintains the integrity of the young sod crop in severe storms. Unlike sprigs or stolons the milled planting stock is produced from whole plant tissue and is comprised of many plantlets with intact root, stem, and leaf tissue. A bushel of milled turf plantlets is much more dense than a bushel of sprigs or stolons and comprises meristems from all parts of the plant including roots, crowns, and rhizomes.

Abstract: An innovative liquid mulch apparatus for the production of thin, lightweight and fastly growing sod over an impervious surface such as plastic sheeting are provided. The apparatus of the invention includes, among other components, a transportable agitating tank and a trailing planter assembly that facilitates the liquid mulch method of manufacturing sods.

Abstract: A device which cuts sods that are grown over plastic sheeting without cutting or damaging the plastic sheeting which is then retained in place to be used again for subsequent crops. The cutter performs four functions: (1) it inserts a vibrating lifting plate between the plastic and the sod and separates and lifts the sod off the plastic; (2) it conveys the sod to the cutting mechanism; (3) it cleanly cuts the sod; and (4) it leaves the plastic undamaged. After cutting, the sod can be harvested by a roller attached behind the cutting mechanism so that the cutting and rolling are done in one operation or the rolling can be done separately at a later time. The mechanism can be arranged in multiples on a toolbar; and the cutter can be attached to conventional sod harvesting equipment with only slight modification.
