Continuous increase in the population of the world along with multiple nutrient deficiencies and poor water use efficiency offers a challenging scenario for agriculture sector to meet the increasing demand of food. Use of organic amendments like biochar and compost has been suggested as a novel approach for restoration of degraded soil further improving crop productivity and water productivity. Thus here, we have reviewed the publications on individual and combined application of biochar and compost to find out the potential role of these amendments in agriculture sector. We have concluded that (1) data on well-designed field studies and long-term effect of biochar and compost is limited; (2) traditional methods have been adopted for production of biochar and compost; and (3) biochar and compost have the potential to enhance soil fertility, crop production and water productivity with reduced environmental impacts. Furthermore, combined application of biochar and compost found to be more effective as compared to sole application of these amendments. This review article will play a dynamic role for scientists to conduct research to evaluate these ecological fertilizers best suited for soils, which will be helpful to reduce the chances of soil degradation caused by application of unsuitable amendments. Application of amendments not suitable for a soil may increase the demand of synthetic fertilizers thus making it uneconomical for farmers. Thus, it is suggested for the scientists and policy makers to make a great collaboration to implement this promising technology worldwide.

世界人口的持续增长以及多种营养缺乏和水资源利用效率低下，为农业部门满足日益增长的粮食需求提供了一个具有挑战性的场景。已建议使用生物炭和堆肥等有机改良剂作为恢复退化土壤的新方法，进一步提高作物生产力和水生产力。因此，在这里，我们回顾了关于生物炭和堆肥的单独和组合应用的出版物，以找出这些修正在农业部门中的潜在作用。我们得出的结论是：（1）关于精心设计的田间研究和生物炭和堆肥的长期影响的数据是有限的；(2)采用传统方法生产生物炭和堆肥；(3) 生物炭和堆肥具有提高土壤肥力的潜力，减少环境影响的作物生产和水生产力。此外，与单独应用这些修正物相比，生物炭和堆肥的组合应用更有效。这篇综述文章将对科学家进行研究以评估这些最适合土壤的生态肥料发挥积极作用，这将有助于减少因施用不合适的改良剂而导致土壤退化的机会。施用不适合土壤的改良剂可能会增加对合成肥料的需求，从而使农民不经济。因此，建议科学家和政策制定者进行良好的合作，以在全球范围内实施这项有前途的技术。发现与单独应用这些修正物相比，生物炭和堆肥的组合应用更有效。这篇综述文章将对科学家进行研究以评估这些最适合土壤的生态肥料发挥积极作用，这将有助于减少因施用不合适的改良剂而导致土壤退化的机会。施用不适合土壤的改良剂可能会增加对合成肥料的需求，从而使农民不经济。因此，建议科学家和政策制定者进行良好的合作，以在全球范围内实施这项有前途的技术。发现与单独应用这些修正物相比，生物炭和堆肥的组合应用更有效。这篇综述文章将对科学家进行研究以评估这些最适合土壤的生态肥料发挥积极作用，这将有助于减少因施用不合适的改良剂而导致土壤退化的机会。施用不适合土壤的改良剂可能会增加对合成肥料的需求，从而使农民不经济。因此，建议科学家和政策制定者进行良好的合作，以在全球范围内实施这项有前途的技术。这篇综述文章将对科学家进行研究以评估这些最适合土壤的生态肥料发挥积极作用，这将有助于减少因施用不合适的改良剂而导致土壤退化的机会。施用不适合土壤的改良剂可能会增加对合成肥料的需求，从而使农民不经济。因此，建议科学家和政策制定者进行良好的合作，以在全球范围内实施这项有前途的技术。这篇综述文章将对科学家进行研究以评估这些最适合土壤的生态肥料发挥积极作用，这将有助于减少因施用不合适的改良剂而导致土壤退化的机会。施用不适合土壤的改良剂可能会增加对合成肥料的需求，从而使农民不经济。因此，建议科学家和政策制定者进行良好的合作，以在全球范围内实施这项有前途的技术。
