Seed as Nitrification Inhibitor creator: Sahrawat, K L creator: Parmar, B S subject: Soil Science subject: Fertilizer Applications description: After removal of the ethanol solvent, the extractive, which is rich in lipid associates, was incubated in soil with 200ppm NH4-N at rates of 5 to 30% of the NH4-N. NH4-N was supplied by ammonium sulphate and urea. Inhibition of nitrification depended on the amount of the seed extract applied and on time of incubation; application at 30% of the NH4-N was effective up to 75 days. publisher: Indian Society of Soil Science date: 1975 type: Article type: PeerReviewed format: application/pdf language: en identifier: http://oar.icrisat.org/4513/1/Alcohol_Extract_of_Neem_%28Azadirachta_indica_L.%29_Seed_as.pdf identifier: Sahrawat, K L and Parmar, B S (1975) Alcohol Extract of Neem (Azadirachta indica L.)
