Sustainable phosphorus use: 'Feed the crop not the soil '


Date: 29/10/2014


A new review into sustainable phosphorus use calls for more precise phosphorus management and suggest novel methods for its application by targeting the crop instead of the soil. The researchers, Paul Withers, at Bangor University, UK, and colleagues argue that when phosphorous is applied to the soil a large proportion is immobilised by chemical and biological processes, making it difficult for plants to access. The researchers suggest to target the crop rather than the soil and propose solutions that include targeted application methods to the root, or with seed dressing and foliage feed.
