Improved compositions for the nutrient of the soil and process for use of the same

摘要

Invention patent: b "improved soil nutrient compositions and process for use of the same" d .Compositions and processes are provided for lowering the pH of the soil in which the compositions comprise ammonium sulfate, elemental sulfur and a micronutrient selected from the group consisting of zinc,Iron, manganese, copper, boron, cobalt, vanadium, selenium, silicon, nickel, and mixtures thereof.In the preferred mode.The compositions are in granulated form and are applied to soil, in order to create microenvironments of lower pH in the soil without lowering the pH of the soil aggregate bulk that surrounds the microenvironments.In microenvironments.The micronutrients are easily available to the roots of plants and are removed by plants with greater efficiency, thereby reducing the amount of nutrients needed to be apLicados to soil.
