Article
Potassium (K) is one of the essential nutrients required by crops in large quantities; however, its use in agriculture by farmers is less than required in developing countries. This neglect has led to excess mining of K in soils by crop plants and has resulted in a negative balance of K in soils. This loss necessitates the need of more use of potas...

Terrestrial ecosystem is the predominant agroecosystem in India in which N is the most widely used input. Nitrogen has played a key role in food grain production, although its use efficiency (20-50%) is very low in India and the recovery of residual N to succeeding crops is also very limited (<7% of applied N). Anthropogenic reactive N (Nr) in the...

Soil cracks are a unique feature of black vertisols. Evaporation loss is inevitable from lateral exposure of surface and sub-surface cracks. On the other hand, these cracks provide increased opportunity for soils to recharge during the rainy season. In this process, water that drains into larger size cracks moves down the soil profile and eventuall...
