In South Asia, 90 percent of smallholder farmers using fertilizer lack access to soil testing services. Due to blanket recommendations, the application of nutrients is not well-matched to the local requirements of the soil and crop. Also, excessive and imbalanced use of chemical fertilizers can result in the deterioration of soil fertility. This is becoming a cause for concern to the Indian agriculture sector. According to a study published in the Journal of the Environment, Development and Sustainability, India is losing soil 30 to 40 times faster than the natural replenishment rate. The solution lies in part in having a precise, site-specific nutrient management approach that will build a sustainable and profitable agriculture sector.
