Bio-fertilization is a sustainable agricultural practice that includes using bio-fertilizers to increase soil nutrient content resulting in higher productivity. Soil micro-flora has been exposed to improve soil fertility and increase biomass productivity and identified as a correct environmentally friendly bio-based fertilizer for pollution-free agricultural applies. The majority of cyanobacteria can fix nitrogen from the atmosphere and several species including ., sp., and is known to be effective cyanobacterial based bio fertilizers. , , , , and sp. are some of the green microalgae and cyanobacteria species that have been successfully used as bio fertilizers to boost crop growth. Also, is one of the most commonly used microalgae in bio fertilizer studies. The addition of seaweed species that are . and leads to chemical changes as a soil fertility indicator on clay and sandy soils, and the addition of seaweed conditioner to soil can improve its organic content, return pH to normal, and reduce C/N ratio in both sandy and clay soil. This review provides an effective approach to increase soil fertility via environmentally friendly bio-based fertilizer using micro and macro algae. Instead of the usage of inorganic and organic fertilizers that have polluted impacts to soil as aggregation of heavy metals, in addition to there their human carcinogenic effects.
生物施肥是一种可持续的农业实践，包括使用生物肥料来增加土壤养分含量，从而提高生产力。土壤微生物区系已被用于改善土壤肥力和提高生物量生产力，并被确定为一种适用于无公害农业的正确的环境友好型生物基肥料。大多数蓝藻可以从大气中固氮，包括.、 sp.和 在内的几种蓝藻被认为是有效的基于蓝藻的生物肥料。 、 、 、 和 sp.是一些已成功用作生物肥料以促进作物生长的绿色微藻和蓝藻物种。此外， 是生物肥料研究中最常用的微藻之一。添加.和 的海藻物种会导致作为粘土和沙质土壤肥力指标的化学变化，向土壤中添加海藻调理剂可以提高其有机含量，使pH值恢复正常，并降低沙质和粘土土壤中的碳氮比。本综述提供了一种通过使用微型和大型藻类的环境友好型生物基肥料来提高土壤肥力的有效方法。与其使用对土壤有污染影响（如重金属聚集）且具有人类致癌作用的无机和有机肥料。
