Soil Fertility (Nutrient Cycles)

This topic builds on Form 1 Soil Science by delving into the biogeochemical cycles that sustain soil fertility. Learners will demonstrate understanding of the nitrogen and carbon cycles, illustrating how these nutrients move through the soil, plants, atmosphere, and water. The focus is on applying knowledge of these cycles to manage and improve soil fertility practically. This competence-based topic is vital for answering ECZ examination questions on sustainable agriculture and soil management. It equips Zambian students with the scientific principles needed to enhance crop production and contribute to national food security goals.
