Organic farming, also known as ecological farming or biological farming, is an agricultural strategy that emphasizes crop rotation and companion planting practices while using organic fertilizers such as compost manure, green manure, and bone meal. It arose in the early twentieth century in response to rapidly changing farming techniques. Certified organic agriculture covers 70 million hectares (170 million acres) globally, with Australia accounting for more than half of that amount. Various groups are still working to enhance organic farming today. Biological pest management, mixed cropping, and insect predator breeding are promoted. Organic standards are intended to permit the use of naturally occurring compounds while forbidding or severely restricting the use of manufactured substances. Naturally occurring pesticides such as pyrethrin, for example, are authorized.
