Precision agriculture uses soil analysis to optimize crop fertilization

Modern agricultural science is increasingly emphasizing precision metrics, such as soil analysis and crop nutrient extraction, to replace traditional, generalized fertilization methods. While many smallholders globally still rely on blanket applications of general-purpose fertilizers, experts suggest this practice can lead to nutrient imbalances, soil degradation, and increased economic costs.

Precision agriculture involves measuring essential macronutrients—including nitrogen, phosphorus, and potassium—alongside soil pH and organic matter. By calculating the specific amount of nutrients removed by crops during growth cycles, farmers can replenish only what is missing. The Food and Agriculture Organization (FAO) notes that balanced nutrient management is vital for maintaining long-term soil health and preventing environmental runoff.
