- Abstract
The requirements of modern agriculture include besides obtaining maximum yields of crops of each ecological region through appropriate agrotechnics also maintaining and improving soil fertility and environmental protection. Traditionally, post-harvest residues of cereals crops in past was used for feed. Nowadays, under the conditions of greatly reduced livestock and lack of market, they have to be exported from the field or burned. This practice leads to deterioration of soil fertility, loss of fresh organic matter, disrupting soil structure and its properties, as well as release of large amounts of CO2. Biomass is a sustainable source of organic carbon. There are many ways of its processing and use. Transformation of biomass into biochar (BC) as a result of pyrolysis has various everyday life applications - heating and barbecues, as well as a soil improver and the composting. In recent years, interest of usage solid phase (charcoal or biochar) obtained by pyrolysis as soil improver increases. The number research concerning biochar applications in order to mimic the effect of fertile soils in the Amazon Terra Petra (Gunarathne, V., 2017) were carrying out in last ten years. The biochar structure, porosity, chemical composition, influence of external factors on the BC properties and its application, distribution and movement in the soil profile is necessary to be studied. In Bulgaria are made research only to determining the influence of systematic plowing of crop residues on the soil fertility and crop productivity on gray forest soil (Medina, J., 2015). The studies of BC influence on the soil properties and plant growth are less. The aim of study is to testing of biochar agronomic impact on the water physical, agrochemical properties of soil and on the growth, plant development and some of their quality indicators.
