Soil Science & Fertility

Soil science studies the physical, chemical and biological properties of soils and how to manage them for long-term productivity and environmental health. Modern practice combines field sampling, lab analytics (CEC, SOC, micronutrients), digital soil mapping (SoilGrids, NRCS SSURGO) and 4R nutrient stewardship.
