Explanation

a) Definition of the terms hay and silage;
(i) Hay: This is a cut and dried forage (stored) for feeding farm animals

  • Improves nutritional quality of the forage/balanced diet
  • Legumes fertilize the soil for grass to grow/nitrogen fixation
  • Optimal usage of the land
  • It enhances proliferation of soil fauna and flora leading to
  • improved soil structure, texture and aeration
  • Reduces evapotranspiration or water loss
  • It prevents erosion
  • Legume trails on the grass for more production/High yield/
  • improved income
