Agriculture developments over the last century have led to tremendous advancements in farming technologies. Due to these developments, the field of soil productivity is rapidly degraded and jeopardized. Researches have been innovating and testing technologies to improve soil’s quality. The increased interest of soil productivity has led to the development and spread of biochar. Improving soil’s productivity has been the result of the evolution of fertilizer, nanotechnologies to improve the quality of soil, research behind biochar, and experiments conducted with the addition of biochar.

The evolution of fertilizer to modern day fertilizer has been built upon the foundation of key discoveries made by chemists studying the relationship between soil and plants. The use of fertilizer existed by Ancient civilizations of the Egyptians and Romans, by the use of minerals. Significant discoveries of fertilizer were discovered in the 1800s leading into the 20th century. Chemist Justus von Liebig contributed to the understanding of plant nutrition. His work rejected the vitalist theory of humus, arguing about the importance of ammonia. He promoted the importance of inorganic minerals to plant nutrition. When Liebig returned to England his theory failed, as the fertilizer produced by treating phosphate of lime in bone meal with sulfuric acid, could not be absorbed by plants. In 1842, Sir John Bennet Lawes produced a practical superphosphate from phosphates in rock and coprolites.…
