Abstract
The present invention provides a soil composition having improved water retention. The composition comprises soil particles and Bacillus subtilis UD1Q22. For example, the composition may comprise soil particles having a particle size no greater than 2 mm and at least 50% of the soil particles have a particle size in the range of 0.05-2 mm. A method for improving water retention of a soil composition is also provided. The method comprises applying an effective amount of Bacillus subtilis UD1022 to the soil composition to improve water retention of the soil composition.
Claims17
A soil composition, comprising at least 80 wt % soil particles having a particle size no greater than 2 mm and at least 0.1 wt % Bacillus subtilis UD1022 in an amount effective for reducing water evaporation rate of the soil composition, each based on the total weight of the soil composition, wherein at least 50% of the soil particles have a particle size in the range of 0.05-2 mm.
A method for reducing water evaporation rate of a soil composition, wherein the soil composition comprises at least 80 wt % soil particles having a particle size no more than 2 mm and at least 50% of the soil particles have a particle size in the range of 0.05-2 mm, comprising applying to the soil composition Bacillus subtilis UD1022 in an amount effective for reducing water evaporation rate of the soil composition.
