Disclosed are micronutrient chelate compositions and methods that provide nutrients to a plant to improve growth while controlling pathogens, such as Candidatus Liberibacter asiaticus the causal pathogen for citrus greening disease, by improving plant health through the enhancement of beneficial microbial populations resident in the plants phloem. The chelate compositions include a combination of a metal, such as iron, and a derivative of a chelating agent such as EDDHA or HBED. The chelate formulations can either be a dry formulation or liquid formulation that is dispersed in a selected amount of water and applied to the foliage of a plant and/or applied to the soil proximal to the plant rhizosphere.

A homogenous granular paper mulch including fertilizer (with the fertilizer composed of natural and/or conventional synthetic ingredients). The mulch is a granular solid composed of recycled paper, fertilizer, and water. The granular product is easy to handle and apply and provides an improved environment for germinating seed.
