Detailed explanation of the organic environment​

Answer 1

• Sustainability over the long term. Many changes observed in the environment are long term, occurring slowly over time.
• Organic agriculture considers the medium- and long-term effect of agricultural interventions on the agro-ecosystem.
• It aims to produce food while establishing an ecological balance to prevent soil fertility or pest problems.
• Organic agriculture takes a proactive approach as opposed to treating problems after they emerge.
• Soil. Soil building practices such as crop rotations, inter-cropping, symbiotic associations, cover crops, organic fertilizers and minimum tillage are central to organic practices.
• These encourage soil fauna and flora, improving soil formation and structure and creating more stable systems. In turn, nutrient and energy cycling is increased and the retentive abilities of the soil for nutrients and water are enhanced, compensating for the non-use of mineral fertilizers.Such management techniques also play an important role in soil erosion control.
• The length of time that the soil is exposed to erosive forces is decreased, soil biodiversity is increased, and nutrient losses are reduced, helping to maintain and enhance soil productivity.
• Crop export of nutrients is usually compensated by farm-derived renewable resources but it is sometimes necessary to supplement organic soils with potassium, phosphate, calcium, magnesium and trace elements from external sources.
