Abstract
The present invention provides a phosphorus solid-phase buffering system that can be spatially localized, i.e., banded on top of, or at specific depths, in media, e.g., soil, by which phosphorus concentrations in the media are reduced or maintained at levels sufficient for optimal plant performance. Also provided are methods for improving the cultivation of plants growing in different media. The present invention provides benefits, such as reduced water and pesticide requirements, reduced phosphorus leaching and runoff, and enhanced root growth. The invention can be used in connection with containerized or field-grown plants, e.g., crops, grasses, trees, and the like. The invention is particularly useful for greenhouse and nursery plants, ornamental propagation, vegetable and bedding transplants, and for turf used for stadium fields, golf courses, lawns and the like, where phosphorus leaching is particularly undesirable.
