Agricultural lime (Aglime) plays a critical role in improving soil quality and increasing food production. This SACAA overview explains how lime, typically produced from crushed limestone, is used to correct soil acidity, enhance nutrient availability, and support healthier crop growth. By increasing soil pH and supplying essential minerals such as calcium and magnesium, Aglime creates optimal conditions for plant development and microbial activity. The guide also highlights how proper lime selection, particle size, and chemical composition influence effectiveness, helping farmers reduce input costs while improving yields.
