Explain four factors that influence the depth of planting crops
Factors influencing depth of planting.
- Soil type – seeds emerge from greater depth in sandy soils that are light than in clay soils.
- Soil moisture content: seeds are planted deeper in dry soils in order to place them in a zone with moist soil.
- Size of seed: larger seeds are planted deeper in the soil since they have enough reserves to shoot and emerge through the soil.
- Type of germination: seeds with epigeal type of germination e.g. beans are planted shallower than those with hypogeal type of germination.
