Agriculture by utilizing the ecology of the forest (plantation forests, forest gardening) is one of the food production system in prehistoric times believed is the first utilization of agricultural ecosystems.

Synthetic fertilizers have been made in the 18th century, in the form of superphosphate. Then ammonia-based fertilizers began to be mass produced when the Haber process was developed during World War I. This fertilizer is cheap, nutritious, and easily transported in bulk form. The development also occurred in chemica pesticides in the 1940s, prompting the use of agricultural chemicals on a large scale throughout the world. [4] But the new farming system that began to develop this a serious impact in the long term on soil compaction, erosion, declining soil fertility overall, also impacts on the human health effects of toxic chemicals that get into food.

Soil biologists began to develop theories about how biology can be used in agriculture to overcome the negative impacts of agricultural chemicals without reducing agricultural production. Biodinamika biology evolved in the 1920s and into the early versions of the organic farming system known today is based on the philosophy of Rudolf Steiner's anthroposophy.

In the 1930s and early 1940s, leading botanists Sir Albert Howard and his wife Gabriel Howard develop organic farming. Howard was inspired by their experiences of traditional farming methods in India, their knowledge of biodinamika, and their educational background. [6] Sir Albert Howard can be regarded as the "father of organic agriculture" because he was the first to apply scientific principles in a variety of traditional farming methods and natural.
