Effect of Biochar Addition to Soil on Plant Quality

Abstract

Thermal decay of organic compositions under a non-oxygen condition causes the production of biochar. Biochar is an organic matter used as a soil amendment, with the intent to improve soil properties. Biochar is a valuable source to produce medicinal compounds due to its fewer side effects and economically efficient properties. Biochar feedstock is mostly obtained from farm wastes, and its nature, type, and origin determine the quality and composition characters of biochar. Besides, adding biochar to soil improves the soil retention, increases its nutrition concentration, has potential to improve the poor soil quality, and improves the growth rate and yield of plants. In this short review, we reviewed the effects of biochar on nutrition value of medicinal plants and crops. However, the composition of biochar and its nutrient availability are studied. Moreover, the environmental solutions of using biochar and the benefits biochar provides such as higher crop yields, increased fertilization efficiency, and more plant growth besides preventing nutrition discharge into the groundwater were reviewed. In addition, the production of a secure habitat for favorable microbial activity, which causes a boost in soil nutrients, besides other biochar properties, characters, and impacts on soil, plant growth, and environment is discussed.
