Organic farming is an agricultural system originated in early 20th century in reaction to rapidly changing farming practices. It relies on fertilizers of organic origin such as compost manure, green manure, and bone meal and places emphasis on techniques such as crop rotation and companion planting. Biological pest control, mixed cropping and the fostering of insect predators are encouraged. In general, organic standards are designed to allow the use of naturally occurring substances while prohibiting or strictly limiting synthetic substances. For instance, naturally occurring pesticides such as pyrethrin and rotenone are permitted, while synthetic fertilizers and pesticides are generally prohibited. Synthetic substances that are allowed include copper sulfate, elemental sulfur and Ivermectin. This session discusses organic farming having several advantages such as sustainability, openness, self-sufficiency, independence, health, food security, and food safety.
