Soil Fertility Constraints
General soil fertility constraints for crop productivity
Before one century in Sikkim with low population density, the equilibrium between natural resources of hills and soil degradation was least and allowed the sustainable agriculture albeit as relatively lower productivity levels. At present high demographic pressure has resulted wide spread expansion of steep land agriculture. These are the soils most at risks from degradation, partly because of their inherent limitations. The following are the main soil productivity constraints.
1. Steep sloppy land leading to high soil erosion and thus loss of soil fertility resulting in low yield.
2. High soil acidity and associate problems.
3. Light texture of soil leaching losses of nutrients through water under high rainfall conditions. 4. High phosphorus fixation capacity of soil.
5. Release of soil nitrogen is low acidic soil and cold temperature.
6. Low efficiency of fertilizer utilization due to smaller size of land holding and rugged hilly terrain
7. Slow rate of transfer of modern technology coupled with lack of awareness and realization of technology.
