Soil properties are sensitive to changes in the soil environment as influenced by vegetation, climate and inputs and losses of biomass and nutrients. Thus, the cropping systems with different management practices are likely to influence soil properties. Grid based soil survey was conducted in Mudhol[r]

What is the peculiarity of sawdust from the beech, etc.? What is a peculiarity of soot? Why may soot be used as a top dressing without losing its ammonia? Sawdust in its natural state is of very little value to the land, but when decomposed, as may be done by the same met[r]

nitrate for corn was 23 to 26 mg N/kg f or a 30 cm depth. Sampling 60cm deep improved cor-relations between corn grain yields and soil nitrate, but it was felt that the improvement did notjustify the additional costs of deep sampling. The critical concentration for the 60cm depth was16[r]

Thus, native species will face novel environmental conditions – and will have precious little time to adjust. Even if the changes in climate are gradual, it has been recognized that the changes will be steep. Species with limited ability to move will have an especially difficult time k[r]
