Abstract: This disclosure relates to a method for controlling the rate at which volatile organic compounds from a soil fumigant are emitted from soil, and, more particularly, to a method for reducing emissions of an applied fumigant in the soil so that fumigant efficacy and safety are improved, and unwanted environmental effects are reduced.

Abstract: This disclosure relates to a method for controlling nutrient depletion and reducing nitrogen and phosphorus run-off in agricultural applications. It is contemplated that the methods described herein maintain more available nitrogen and phosphorus in the plant root zone and minimize premature leaching and loss of the plant nutrients into surface waters and the subsurface ground water. The nutrient depletion-restricting substance includes a liquid formulation comprising one or more of the following components: (1) a plant extract from algae, seaweed, or their derivatives; (2) a liquid plant growth modification composition (3) a humic extract from a genuine humic source, e.g., leonardite.
