3. a) i. Clearing vegetation (e.g., slashing, burning, uprooting weeds). ii. Primary tillage (e.g., ploughing, digging) to break up the soil. iii. Secondary tillage (e.g., harrowing, raking) to refine the seedbed. iv. Leveling the land. b) i) Primary cultivation involves the initial, deep breaking up of the soil to turn over the land, incorporate crop residues, and improve aeration. It is typically done using implements like mouldboard ploughs or disc ploughs. Secondary cultivation follows primary cultivation and involves shallower operations to refine the seedbed, break down clods, control weeds, and level the soil surface. It is done using implements like harrows, cultivators, or rotavators. c) i. To create a fine, firm, and level seedbed suitable for seed germination and root development. ii. To control weeds and pests, reducing competition for nutrients and water. 4. a) Conservation tillage is a method of land preparation that minimizes soil disturbance and leaves a significant amount of crop residue (at least 30%) on the soil surface after planting. This practice aims to reduce soil erosion, conserve soil moisture, and improve soil health. b) i. No-till/Zero tillage: This practice involves planting crops directly into undisturbed soil without any prior tillage. All crop residues from the previous harvest are left on the soil surface, forming a protective mulch. ii. Minimum tillage: This practice reduces the number of tillage operations compared to conventional methods. It involves less intensive soil disturbance, often using implements that only partially invert the soil or cultivate narrow strips, leaving a substantial amount of residue on the surface.
