AGROFORESTRY ANSWERS
1. two reasons for seed treatment of tree species before planting
- Break dormancy
Control pests and diseases
2. four ways by which Re-afforestation help in land reclamation
- Add organic matter from falling leaves
- Recycles soil erosion
- Control soil erosion
- Improve drainage of swampy areas
Play part in hydrological cycle
3. four advantages of agro forestry
- Source of wood fuel (energy)
- Source of income
- Conserve environment/reduce soil erosion/improve water catmint
- Source of food /fruits
- Medicine/value
- Aesthetic value
- Feed for livestock
- Labour saving
5. (a) A – Pollarding technique (½mk)
