Document Summary
Give one of jules pretty"s key principles of agriculture sustainability: provide knowledge to farmers, focuses on minimizing, not eliminating. How would you define intensification: using everything that is available, using natural, social and human capital assets combined with the best available technologies and inputs. Intensive systems: large amounts of labour and capital relative to land area, might involve the use of fertilizer, insecticides, fungicides and herbicides, high-efficiency machinery used for planting. Best management practices: a practical, affordable approach to conserving, example, conservation tillage, riparian buffer strips. Reduces water velocity (erosion) and decreases dissolves nutrients: cover crops and mulch. Increase nutrients n if leguminous (green manure: wind barriers. Water management: best irrigation management practices, water quality (e. g. riparian buffer strips, water hydrating (get notes from cl) Nutrient management: using things like legumes, manure and compost can help with managing nutrients, practices to reduce losses, precision agriculture.
