Description It is anticipated that the climate change variables
such as aberration in temperature, frequent
occurrence of droughts and/or floods would have
greater impact on soil related problems like moisture
deficit and mineral stresses (suboptimal
availability of mineral nutrients). Plants response
to these stresses is complex because it involves the
interaction of soil, plant and climatic variables.
Many crops in developing countries are supported
by weathered soils in which either nutrient deficiencies or ion toxicities are common.
Many systems have declining soil fertility due to inadequate use of fertility restoring
inputs, ongoing soil degradation, and increasingly intense resource use. For example,
most of the tropical vegetation is supported by weathered soils with some combinations
of low N, P, K or micro-nutrients or toxicity of Al, Mn, etc. Each of these stresses has
complex yet, distinct interaction with climate change variables, making it very difficult
to predict how plants in such environments will respond to future climate change
scenarios. Potential effect of climate change on soil fertility and the ability of crops to
acquire and utilize soil nutrients are hitherto poorly understood though, are essential
for understanding the future of agriculture.
