Title

Effect of Type, Amount and Biochar Particles Size on Porosity, Penetration Resistance and Stability of Aggregates in a Calcareous Soil

Pages

  113-128

Abstract

 Recently, biochar has been considered as a soil conditioner. In research, the effect of the type and amount of biochar on soil properties has been emphasized. This field study was conducted to investigate the combined effect of type, amount and size of biochar particles on total porosity (TP), penetration resistance (PR), Mean weight diameter of aggregates (MWD) in a sandy loam texture. A Factorial experiment was performed as a randomized complete block design with three factors of type, amount and biochar particles size in three replications. Wheat straw, vermicompost and apricot firewood biochar were added to the soil in 0. 5, 1. 5 and 3% and particle sizes of 0. 5, 0. 5-1 and 1-2 mm. All three biochar increased TP significantly and decreased PR significantly compared to control. Biochar type had the largest contribution in TP and PR changes. The highest TP was obtained in wheat straw biochar treatment with 3% and particle size of 1-2 mm. The greatest decrease in PR was observed in wheat straw biochar with a value of 3% and a particle size of 0. 5-1 mm. Interaction of type, amount and size of biochar particles had the largest contribution in MWD change. The largest MWD (1. 22 mm) was observed in wheat straw biochar with biochar amount of 0. 5% and particle size of 0. 5 mm. The results showed that the amount and size of biochar particles had different effects on soil properties depending on the type of biochar.
