Sustainable agricultural management approaches in the soil environment is the key to sustained food security, soil quality and livelihood security. The damage to soil fertility and depletion of plant nutrient elements in soil has emerged as major threats to the sustainability of diverse agricultural production systems. Therefore, soil and water testing is considered an important tool to assess the essential plant nutrient elements need to formulate crop and site specific nutrient recommendations vis-à-vis climate change strategies. Soil test based nutrient use optimizes economic returns and minimizes risks of environmental pollution. Characterization of soil mineralogical, microbiological or biochemical properties within an experimental area among different treatments or cropping systems it requires the utmost attention to planning details. It is imperative to establish experimental objectives as a prelude to developing the sampling plan. As a component of development of sampling plan
