A plant metabolism promoting composition for promoting metabolic processes in plants includes an L-amino acid, or a salt or a derivative thereof, having a chemical formula of HO.sub.2CCH(NH.sub.2)CH.sub.2CH.sub.2CONHR, wherein R is an alkyl or an alkenyl. An amount of the composition applied to one or both of a seed and a plant is sufficient to augment one or more of: i. growth of a plant growing from the seed or growth of the plant, ii. health of a plant growing from the seed or health of the plant, iii. quality of yield from a plant growing from the seed or quality of yield from the plant, and iv. quantity of yield from a plant growing from the seed or quantity of yield from the plant.

A process for treating plants, including the application of at least one compound, termed carbonic ester of glycerol, including at least one carboxylic ester function formed by a carbonic acid-derived group and at least one glycerol-derived group, with the exception of cyclic glyceryl carbonate including five ring members.

The present invention is directed to methods of treating a plant having a plant part. One method involves providing a plant having a plant part; applying an aqueous treatment formulation to the plant, where the aqueous treatment formulation comprises a thickener, a water soluble divalent salt, a foam control agent, a complexing agent, a film forming agent, and water; and harvesting the plant part, where the aqueous treatment formulation, when applied to a surface of a plant, creates a water fast film on the surface that permits permeation of an aqueous material to the plant while minimizing loss of moisture or loss of a plant treatment chemical from the plant as compared to when the composition is not applied to the surface of the plant. The present invention also relates to a methods of treating a harvested plant part and to the treated harvested plant parts.

Solid acidic fertilizer granules, methods for producing the same, and methods for their use in fertigation, are disclosed. The solid acidic fertilizer granules include a plant nutrient and one or more inorganic acid distributed throughout the granules. The amount of the inorganic acid is sufficient to adjust the pH value of the fertigation solution containing the dissolved fertilizer granule to an acidic pH and prevent or reduce the precipitation of calcium in the fertigation solution.
