Slow release fertiliser can revolutionise agriculture | ||||||||

Sri Lankan scientists have developed a simple way to make a benign, more efficient fertiliser that could contribute to a second food revolution, it is claimed. The nanoparticle-based "slow release" nitrogen fertiliser they have successfully tested in rice fields can simultaneously cut down the emission of greenhouse gas associated with agriculture, they report in the American Chemical Society journal ACS Nano. Nitrogen is an essential nutrient for crops. Urea is a rich source of nitrogen and so farmers currently use it to fertilise the soil. But urea breaks down quickly in wet soil, resulting in the evolution of ammonia before it can be efficiently adsorbed by the plants.
