Organic agriculture, which uses only non-synthetic pesticides, has grown and in 2020 represents about 1.5 per cent of the world's total agricultural land. [15] Pesticides have become more effective. Application rates fell from 1,000 to 2,500 grams of active ingredient per hectare (g/ha) in the 1950s to 40–100 g/ha in the 2000s. [15]
An organic movement began in the 1940s as a reaction to agriculture's growing reliance on synthetic fertilizers and pesticides. The history of this modern revival of organic farming dates back to the first half of the 20th century at a time when there was a growing reliance on these new synthetic, non-organic methods.
The organic movement began in the early 1900s in response to the shift towards synthetic nitrogen fertilizers and pesticides in the early days of industrial agriculture.A relatively small group of farmers came together in various associations: Demeter International of Germany, which encouraged biodynamic farming and began the first certification program, the Australian Organic Farming and ...
In second place, Minula Weerasekera, a ninth grader from Beaverton, Oregon, developed a solution for storing energy for longer through organic compounds and a sulfur-based terhiophene, 3M announced.
Pesticides, because they are toxic chemicals meant to kill pest species, can affect non-target species, such as plants, animals and humans. Over 98% of sprayed insecticides and 95% of herbicides reach a destination other than their target species, because they are sprayed or spread across entire agricultural fields. [ 17 ]
In particular, the concepts of non-tillage, relay cropping, cover-cropping, and plant biodiversity have been shown to prevent soil loss, reduce or eliminate the need for pesticides or fertilizers, and reduce flooding, while increasing water retention, and providing habitat for insects that contribute positively to both crop and ecosystem health.
For most of its history, agriculture has been organic, without synthetic fertilisers or pesticides, and without GMOs. With the advent of chemical agriculture, Rudolf Steiner called for farming without synthetic pesticides, and his Agriculture Course of 1924 laid the foundation for biodynamic agriculture . [ 192 ]
He advocated for agricultural biotechnology as he had for pesticides in earlier decades: publicly, knowledgeably, and always despite heavy criticism. [30] [27] Borlaug served on the faculty of the University of Minnesota, University of Iowa, Cornell University, and Texas A&M University. Borlaug remained at A&M until his death in September 2009.
