Agronomic Effect of Combined Application of Biochar and Nitrogen Fertilizer: A Field Trial

Wei Zheng, Brajendra K. Sharma

Research output: Chapter in Book/Report/Conference proceedingChapter


From the standpoint of increasing agronomic yields, it is crucial to add proper biochars to fitting soils for appropriate plant growth under suitable environmental conditions. For fertile soils, combined applications of biochar and chemical fertilizers or compost can be effective and feasible in improving plant growth and increasing crop yields. This chapter presents a field trial which was conducted in fertile Illinois agricultural soils and assesses the potential effects of the combined application of biochar and nitrogen fertilizer on agronomical production. It describes the materials and methods used for the field trial including overviews of field experimental design and measurements and analyses. The chapter also presents the effects of biochar A and biochar B used as soil amendments on corn yields and the effects of biochar as a soil amendment on soil quality.
