Differential effects of nitrogen and phosphorus additions on the ecology of soil and vegetation of dry tropical forests and derived savanna ecosystems in India

摘要：

Introduction Landscape transformation and atmospheric nutrient depositions,important global change drivers,are rapidly occurring in Indian dry tropical regions supporting natural forest and derived savanna ecosystems.The Vindhyan Plateau,extending across the central part of India,potentially supports tropical deciduous forests have now been degraded into savannas due to anthropogenic influences through centuries.As a result the regional landscape shows vast expanses of savanna,bears intense cattle grazing especially during rainy season,interspersed with variously sized patches of forests ( Singh 1989 ).
