Biochar is a valuable soil amendment; It is a type of bio energy which is produced by the incomplete burning of Biomass. The process creates a fine-grained, highly porous charcoal that helps soils retain nutrients and water.
Biochar can be an important tool to increase food security and cropland diversity in areas with severely depleted soils, scarce organic resources, and inadequate water and chemical fertilizer supplies.
Biochar also improves water quality and quantity by increasing soil retention of nutrients and agrochemicals for plant and crop utilization. More nutrients stay in the soil instead of leaching into groundwater and causing pollution.
