Influence of biochar on soil physicochemical traits and Triticum durum L. physiology during abiotic stress

Journal Title: Agropastoralis Scientia - Year 2024, Vol 1, Issue 2

Abstract

Improving soil nutrient reserves through effective land management practices and pasture utilization is a continuing focus in agricultural discussions. Among the various methods aimed at boosting crop productivity, the use of mineral or organic fertilizers is prominent. Biochar, a carbon-rich substance derived from the pyrolysis of organic residues, is commonly employed as a soil amendment to enhance fertility and improve soil characteristics. This study aims to evaluate the impact of biochar on soil physicochemical properties and the yield of a vital forage crop: durum wheat. Three different doses of biochar were applied (D0 = 0g of biochar, D1 = +20g/pot, and D2 = +60g/pot), in conjunction with two types of water and salt stress. Water stress levels were categorized into four stages (S1 = 100%, 80%, 40%, and 20% of field capacity), while salt stress was administered at three varying concentrations: S0 = 0g of NaCl/l, 4g of NaCl/ l, and 9g of NaCl/l. The results indicate an increase in pH (7.77) and electrical conductivity (1369.13 µS/cm), accompanied by a noticeable improvement in nitrates (7.36 mg/g of soil). Significant increases were also observed in total carbon (2.83%) and soil moisture (8.81%), along with a substantial accumulation of active limestone (3.60%). The plant's response to biochar was particularly notable, especially in terms of chlorophyll levels (3.88µg/g FW) and leaf water content (45.54%)
