Continuous and excessive use of synthetic fertilizers in food production generates strong pressure on agroecosystems. Therefore, it is necessary to study standardize alternatives that promote environmental health, such as biochar. Biochar (a blackish solid obtained from the pyrolysis vegetable waste, industry animal or water processing waste) characterized by its high content mineral carbon, presence functional groups, richness nutrients potassium (K+). Its soils improves organic matter cation exchange capacity (CEC), which promotes crop nutrition. In addition describing biochar manufacturing processes, this chapter aims emphasize role a fertilizer, stimulating effects soil microbiome enzymatic activity, positive plant health. Understanding biofertilizer can be considered an ecological strategy for production. However, agricultural sector must consider limitations fertilizer.

Abstract The enhancement of saline soil yield potential by biochar was well-documented, but the changes brought particle size on properties and crop performance are not well understood. To investigate in tomato due to under varying salt stress, we conducted a pot experiment China Northwest’s solar greenhouse. A total nine treatments were applied, with three different amounts [S0 (no salt), S1 (0.3% dry weight), S2 (0.6% weight)], B0, B1, B2 (0, 0.5% large particles small particles). Adding did significantly affect measured chemical properties, except for pH, nitrogen (TN), Ca 2+ . Specifically, addition increased pH TN, while reduced 2 ⁺ content likely selective adsorption ⁺. Biochar had opposite effects stress levels. Compared S0, B1 19.1% 36.5% higher, whereas B2, 33.1% 44.2% lower S2, respectively. Under no small-size 51.0% compared largely improved water nutrient status. These results great value developing better strategies adding appropriate into soils achieve greater productivity gains. Highlights 16.7–37.9%, there significant difference other cations. Large-size alleviated promoting leaching enhancing nutrients. Small exacerbated salinity higher treatments. boosted without stress.
