Employing fertilizer for farming has a long history dating back 8000 years. In ancient times, manure has been the most logical fertilizer to use. Babylonians, Egyptians, Romans, and early Germans were recorded using minerals or manure to increase yields. The foundation for the modern fertilizer industry was laid by Justus Liebig in 1840, who was concerned with elements needed to plant growth and development. Around 1933 the production of solid ammonium nitrate for fertilizer use began on a significant scale in the United States during World War II. In 1843 Lawes began producing superphosphate of lime. The K fertilizer industry started in Germany in 1861. Rapid boosts given by synthetic fertilizers attracted the farmers. Therefore, demand for synthetic fertilizers increased. The concepts of modern organic agriculture were developed in the early 1900s by Sir Albert Howard, F.H. King, Rudolf Steiner, and others who believed that the use of animal manures (often made into compost), cover crops, crop rotation, and biologically based pest controls resulted in a better farming system. Green growth is the newest concept for agriculture which is the pursuit of economic growth and development while preventing environmental degradation, biodiversity loss, and unsustainable natural resource use. The goal is to increase the chances of using cleaner sources of growth, thereby moving to a more environmentally sustainable growth model. Organic fertilizers, other organic agricultural inputs, and farming practices are the foundation of this concept.
