The aim of the present study is to trace the dynamics of soil moisture and bulk ensity in field experiment with adding carbonated plant residues (biochar) to the soil of broad bean.The xperiment was carried out in 2018 on the experimental field of the University of Forestry - Sofia. The experiment was set with two meliorants - biochar (tree different levels) and manure (used as a background). Adding carbonated lant residues to the soil is a good solution for improving some soil properties, reducing fertilizer levels and ncreasing yields. Biochar has been extensively studied in terms of its impact on the water-physical properties of he soil, but only a small part of the results is obtained from field experiments.The soil dampness is crucial for ultivation of agricultural crops. The most accurate assessment of humidification conditions can be made on the content of productive moisture in the soil, because it is the moisture that plants actually use. Measurements carried ut with a high-frequency moisture meter show that the dynamics of soil moisture is a closely related to rrigation regime and climatic conditions.
