PRODUCTIVITY & SUITABILITY ANALYSIS (Rice)
Soil suitability classification refers to the use of a piece of land on a sustainable basis, based on physical and chemical properties and environmental factors. It is the ultimate aim of soil survey and this may come up through a good judgment and a thorough evaluation of soil properties and qualities like soil depth, texture, slope, drainage, erosion, flooding and fertility. Based from these properties, the suitability of a certain tract of land for crop production is determined.
