摘要:
Improved agriculturally useful products are provided, including solid materials such as nitrogenous fertilizers (e.g., urea), together with a polycarboxylated polymer selected from the group consisting of a salts of copolymers containing individual quantities of maleic and itaconic moieties. The polymer composition also includes from about 10-60% by weight of an organic drying agent such as a lower alcohol which enhances the quick drying properties thereof. The compositions may also include an amount of boron, and bimodal vinylic polymer made up of quantities of high and low molecular weight (MW) vinylic polymers such as PVA.

Methods are provided for the treatment of livestock or poultry confinement facilities equipped with manure collection zones (e.g., a manure pit or litter), in order to reduce and mitigate the effects of gaseous ammonia within the facility. The treatment involves application of an aqueous mixture including a partial calcium salt of a maleic-itaconic copolymer and a partial ammonium salt of a maleic-itaconic copolymer. Preferably, the amount of the partial calcium salt copolymer is greater than the amount of the partial ammonium salt copolymer. The treatment methods provide prompt and lasting reductions in gaseous ammonia within the confinement facility.
摘要:
Biodegradable anionic polymers are disclosed which include recurring polymeric subunits preferably made up of dicarboxylic monomers such as maleic anhydride, itaconic anhydride or citraconic anhydride. Free radical polymerization is used in the synthesis of the polymers. The polymers may be complexed with ions and/or mixed with fertilizers or seeds to yield agriculturally useful compositions. The preferred products of the invention may be applied foliarly or to the earth adjacent growing plants in order to enhance nutrient uptake by the plants.

Improved, micronutrient-supplemented polymeric seed coatings are provided which include at least one polyanionic polymer in combination with respective amounts of Zn, Mn, and Cu micronutrients. Preferably, the coatings comprise polyanionic polymers having a backbone comprising dicarboxylic repeat units with Zn, Mn, and Cu bound to the backbone. The most preferred polymers contain maleic and itaconic repeat units, optionally with sulfonate repeat units. The invention also provides a method of treating seeds using the coatings, and coated seed products.
摘要:
Agriculturally useful compositions comprise individual quantities of anhydrous ammonia, ammonia solution, and one or more agricultural actives different than anhydrous ammonia. The compositions may include polyanionic polymers, fertilizers, and/or biocidal agents. Preferably, the compositions are created in pressurized tanks and are applied in the same fashion as anhydrous ammonia.
