Cambridge IGCSE Agriculture — Soil

Led by George Washington Carver Simulacrum

The complete soil module of IGCSE Agriculture — formation, types, fertility, the nitrogen cycle, erosion, drainage and irrigation. Taught by George Washington Carver Simulacrum.

1. Module 2

   Soil: Formation, Fertility and Conservation

   Led by George Washington Carver Simulacrum

   The question

   What is soil, how does it form, and why does it fail? George Washington Carver Simulacrum traces soil from its origin in weathered rock through its layers, constituents and living organisms, through the nutrient cycles that sustain fertility — especially the nitrogen cycle — through the fertilisers and liming practices that supplement it, and through the erosion, waterlogging and poor drainage that destroy it. The session culminates in irrigation and the water cycle: where agricultural water comes from and how to manage it.

   Outcome

   The student can explain soil formation, describe soil types, state major nutrients and deficiency signs, describe the nitrogen cycle, and explain erosion prevention, drainage and irrigation. (Module 2 — Soil)
