An agricultural spray may be produced by admixing citric acid and glutamic acid with a metal salt and a pesticide or other agricultural chemical containing components capable of precipitating with the metal salt in the admixture. The citric acid and the glutamic acid chelate with the metal salt to provide a stability and compatibility-enhancing composition, thereby preventing the metal salt from forming an insoluble solid within the admixture. Such a composition may be produced by admixing citric acid and glutamic acid at a molar ratio of about 6.8:0.5 to about 1:0.29. The composition may include a metal sat, citric acid and glutamic acid in a molar ratio of about 1:6.8:0.5 to about 1:1:0.29 and a pesticide.

A method is disclosed of in-situ retention and buffering of an amount of water in soil to support the growth of an agricultural crop. The method comprises the step of adding an effective amount of a hydrogel material as a water retention agent during planting of seed in the soil. The hydrogel material including an insoluble, cross-linked carboxymethyl cellulose. Once penetration of water into the soil is allowed after the planting of seed, a proportion of the water which penetrates the soil is absorbed by the hydrogel material and, over time, the absorbed water is released by diffusion into the soil to support the growth of the agricultural crop. Also disclosed is the hydrogel material which comprises said carboxymethyl cellulose which has been cross-linked with a cross-linking polymer from the group consisting of: an amine monomer; an amide monomer; and an amine-amide co-polymer.

Some embodiments relate to herbicide compositions and methods of inducing phyotoxicity in a plant, by administering an aqueous composition to foliar portions of the plant. This aqueous composition includes at least one nutrient, and at least one adjuvant, and has a pH of about 4 to about 7. In some embodiments, the aqueous composition comprises an organic or mineral acid. In some embodiments, the phytotoxicity is topical. In some embodiments, the phytoxicity is systemic. Without being limited by theory, the nutrient is absorbed by the plant in excess, thereby killing the plant.

Microbial compositions for application to plants, plant parts and plant seeds are provided for improvement of plant yield and/or other beneficial plant traits. Methods of making and applying microbial compositions or formulations to plants, plant parts or plant seeds or to growth media are further provided to increase or improve plant yield and/or other beneficial plant traits.
