Abstract

Biochar is mainly used in agriculture to increase soil fertility and water retention, which leads to improved plant growth. As a result, it improves the overall productivity of agriculture. A field experiment was carried out on alluvial - meadow soil. Six variants have been developed, with the increasing rate of biochar and organic fertilization as a background. The tested crops are broccoli. The aim of the study is to evaluate the combined application of carbonized plant residues and manure as a soil improver on the yield of broccoli. In the variants with higher biochar content in combination with manure the humus content increases. The addition of carbonized plant residues in combination with organic fertilization can be used as a soil improver and as a means of utilizing plant residues in agriculture.
