| Abstract: |
| With the development of the application of biochar in agriculture, more and more new fertilizers-biocharbased fertilizers （BF）, which are based on biochar and combined with conventional chemical fertilizers or organic
fertilizers, have been developed and tested on crops. Related researches have shown that, biochar-based fertilizer has the
advantages of controlled-release/slow-release of nutrients, improving soil physical and chemical properties, strengthening
drought-resistant capacity, reducing the loss of fertilizer nutrient resources and improving fertilizer utilization rate. It has
been paid more attention to tap the environmental friendly and resource saving potential of biochar based fertilizer. Based on the comprehensive analysis of the published literature on biochar based fertilizer experiments, this paper expounds the
composition materials, fertilizer formulation and granulation technology of various biochar based fertilizers, as well as the
application effects of biochar-based fertilizers on rice, corn, wheat, vegetable, potato, peanut, soybean, tobacco, cotton, forage
and fruit trees, especially research progress in the effects of biochar-based fertilizers on the growth, yield and quality of these
crops and soil. According to the existing problems and technical requirements in the experimental research, the research ideas
of biochar-based fertilizers in the future are put forward, and the comprehensive and systematic research direction on soil
environment, high yield and high efficiency of crops and green ecology are prospected. |
