Abstract

Organic amendments of soil have the ability to enhance crop production and influence soil health by altering its physical and chemical properties. However, studies are limited regarding field evaluation of biochar and compost influence on crop yield and soil health. Therefore, the present study was planned to evaluate the beneficial impact of biochar together with compost on nutritional profile of soil and maize productivity. Cow manure was used as a biomass to prepare biochar and compost. For biochar production the pyrolysis temperature was kept at 480 °C. The experiment comprised of four treatments: (1) Control (2) Biochar (3) Compost, and (4) Biochar + Compost, at the rate of 5 tons ha⁻¹, for each. There was an increase of 46.29% and 13.4% in grain yield and biological yield, respectively, in treatment containing biochar and compost over un-treated control. Similarly, the soil organic carbon has also shown an increase of 80.52% due to the synergistic effect of biochar and compost. However, there was a decline in soil pH by combined application of biochar and compost. Conclusively, biochar and compost have the potential to increase crop productivity with better management of soil nutrients and properties.

摘要

土壤的有机改良剂能够通过改变其物理和化学特性来提高作物产量并影响土壤健康。然而，关于生物炭和堆肥对作物产量和土壤健康的影响的研究还很有限。因此，本研究计划评估生物炭与堆肥一起对土壤营养状况和玉米生产力的有益影响。牛粪用作生物质来制备生物炭和堆肥。对于生物炭的生产，热解温度保持在480°C。该实验包括四个处理：（1）对照（2）生物炭（3）堆肥，以及（4）生物炭+堆肥，处理量为5吨ha ^-1，每个。与未处理的对照相比，含生物炭和堆肥的处理的谷物产量和生物产量分别增加了46.29％和13.4％。同样，由于生物炭和堆肥的协同作用，土壤有机碳也显示出80.52％的增长。然而，生物炭和堆肥的联合施用使土壤pH降低。总之，生物炭和堆肥具有通过更好地管理土壤养分和特性来提高作物生产力的潜力。
