Answer:
6.he main sources for irrigation water are groundwater from wells, surface water, drainage ponds, rain and municipal water. Drilled wells are a clean source of water for many greenhouse operations however, the water yield from drilled wells is usually limited.
7.most farmers remove weeds because they use up the water,minerals and sunlight which are meant for crops.
8.Legumes are of special interest in organic crop rotations because of their ability to add nitrogen to the system. Specialized bacteria (Rhizobium spp.) associated with the roots of legumes convert atmospheric nitrogen (N2 gas) into plant-available nitrogen.
3.Then, when the plants are transplanted in the field, they will grow stronger than those sown in the field because of their strong roots. Transplantation minimizes inputs. Effective irrigation minimizes water wastage during early stages of plant growth pest management removes excessive pesticides
