Organic Fertility of Severely Eroded Soils: Effect of Organic and Inorganic Fertilization and Cropping Patterns [PDF]
, 2010 A study was conducted on farmer’s field for the restoration of fertility status of severely eroded soils in north west Pakistan during 2006 and 2007. Two factors viz fertilizer treatments included T1 (control), T2 (50% NP also called farmer’s practice), T3 (100% NPK) and T4 (20 t·ha−1 farmyard manure integrated with 50% N and 100% PK as mineral ...
