The advances in biochemistry, (nitrogen manure) and technology (the internal combustion engine) at the beginning of the 20th century led to the major changes of the leasing. Produced hybrid seed research of selecting of plants. The fields developed in the face and the emblavage became specialized to make the effective use of the machines and to derive the advantages of the green revolution. Technological progress during the incited Second World War the innovation of post-war period in all the aspects of agriculture, having for result of the advances such as the irrigation on great scale, the fertilization, and the use of the pesticides. The ammonium nitrate, used in ammunition, became an abundantly cheap source of nitrogen. The DDT, at the origin developed by the soldiers with the disease-bearing insects of order among troops, was applied to harvests, launching the era of a widespread utility of pesticide. In Germany, the spiritual bases of Rudolf Steiner for the renewal of agriculture, published in 1924, led to the popularization of the agriculture of biodynamics.



The first use of the biological agriculture of limit is by Northbourne lord. The limit is derived from its concept “of the farm like organization” and that it exposed in its book, glance with the ground (1940), where it described holistique, approach ecologically balanced with the leasing. The British botanist, Mr Albert Howard studied traditional husbandries in Bengal, India. He came to consider practices such as the superior with modern agronomic science and recorded in its 1940 book, an agricultural will and adopted the terminology of Northbourne in its book “the ground and health: An organic study of agriculture” in 1947. Mrs Eve Balfour, author of traditional of organic materials the organic soil, established the pilot experiment of Haughley to her farm of Suffolk into 1939 which functioned during more than 40 years.

With the USA, J.I. Rodale popularized the organic gardening among consumers during the Forties. The Japanese farmer and author Masanobu Fukuoka invented has no-jusquau system for the production of small size of grain which it called Natural Farming. At the beginning of the Forties.

In 1972, the international federation of the organic movements of agriculture (IFOAM), was founded in Versailles, France. IFOAM was devoted to the diffusion of information on the principles and the practices of organic agriculture through national and linguistic borders. In the Eighties, the various groups of consumers of farm and in the whole world started to encourage the payment of government of the organic production. This led to the standards of legislation and certification being beginning issued in the Nineties. Since the beginning of the Nineties, the market with the detail for biological agriculture in developed economies increased approximately 20 percent annually the due one to an increasing request of the consumer.

While the small producers and independent consumers led at the beginning the rise in biological agriculture, while waiting like volume and variety of “organic” products develops, production is more and more on a large scale.
