Seed coating compositions and methods for applying soil surfactants to water-repellent soil

摘要

Herein provided are innovative methods and techniques for improving seedling germination and plant establishment including a seed composition of at least one seed having a seed protective coating applied to the seed and a soil surfactant coating applied to the seed protective coating. The seed protective coating is positioned between the seed and the soil surfactant. The seed protective coating is formulated to keep the soil surfactant from contacting the seed and the soil surfactant coating is formulated to increase wettability of soil and being a sufficient quantity of soil surfactant to treat the soil in contact with the seed composition such that the soil is conditioned for growing the seed.

主权项

1. A seed composition for conditioning soil, the composition comprising;
at least one seed; at least one seed protective coating that comprises a binder and a first powdered carrier, and is adhered to an outside surface of the seed; and a surfactant coating that is disposed on the seed protective coating and that comprises at least one soil surfactant and a second powdered carrier, wherein the first powdered carrier is a germination delay preventer, wherein the seed protective coating is disposed between the seed and the soil surfactant coating to substantially prevent the soil surfactant from contacting the seed, and wherein the soil surfactant is released from the second powdered carrier into the soil upon contact with water, thereby improving moisture availability to an area of soil around the seed.
