Description: Intensive use of fertilizers causes environmental problems such as groundwater contamination and eutrophication of freshwater bodies due to nutrient leaching. There is an increasing demand for eco-friendly and economic soil amendments such as biochar for restoring soil fertility and enhancing sustainable and resilient crop production systems. An outdoor pot experiment was conducted to investigate the effect of wheat straw biochar on nutrient leaching and green pepper plant productivity grown in fertile and less fertile soils. The six chosen treatments were: Fertile soil (FB0%), Fertile soil + 1% biochar (FB0%), Fertile soil + 3% biochar (FB3%), Less fertile soil(LB0%), Less fertile soil+ 1% biochar (LB1%),) and Less fertile soil+ 3%biochar (LB3%),). Treatments were arranged in a randomized complete block design, with one replicate per treatment per block. Plant growth parameters such as greenness, photosynthesis, and multispectral reflectance were measured during the growing season. Green peppers were harvested, and fresh weights of plant biomass and fruits were measured. Adding 3% biochar(w/w) in less fertile soil significantly increased 41 % green pepper yield while 1% biochar had no significant effect than control. Biochar amendment infertile soil (1% and 3%) did not affect plant yield. Biochar application in both soils led to significantly (P<0.05) reduced nitrate and orthophosphate leaching, as well as reduced leachate volume. Thus, it can be concluded that amending the soil with biochar can result in an increase in plant yield and reduced nutrient leaching in less fertile soils.
