Iron pyrites for reducing ammonia volatilization losses from fertilizer urea applied to a sandy clay loam soil

Iron pyrites for reducing ammonia volatilization losses from fertilizer urea applied to a sandy clay loam soil

Current Science 89(5): 742-743

A laboratory incubation study was conducted on a sandy clay loam soil, collected from an experimental field under a rice-wheat cropping system in New Delhi, India, to determine if the addition of pyrites to urea could help in reducing ammonia volatilization (AV) losses. Urea at 56.6 mg N/100 g soil without or mixed with pyrite in 1:1, 1:2 and 1:4 urea:pyrite ratios was surface applied.
