Abstract：
Improving soil quality without creating any environmental problems is an unescapable goal of sustainable agroecosystem management, according to the United Nations 2030 Agenda for Sustainable Development. Therefore, sustainable solutions are in high demand. One of these is the use of biopolymers derived from microbes and seaweed. This paper aims to provide an overview of the sources of extraction and use of microbial (bacteria and cyanobacteria) and seaweed-based biopolymers as soil conditioners, the characteristics of biopolymer-treated soils, and their environmental concerns. A preliminary search was also carried out on the entire Scopus database on biopolymers to find out how much attention has been paid to biopolymers as biofertilizers compared to other applications of these molecules until now. Several soil quality indicators were evaluated, including soil moisture, color, structure, porosity, bulk density, temperature, aggregate stability, nutrient availability, organic matter, and microbial activity. The mechanisms involved in improving soil quality were also discussed.
摘要：
在不造成任何环境问题的情况下改善土壤质量是可持续农业生态系统管理的不可回避的目标。根据联合国2030年可持续发展议程。因此,可持续解决方案的需求很高。其中之一是使用源自微生物和海藻的生物聚合物。本文旨在概述微生物（细菌和蓝细菌）和海藻基生物聚合物作为土壤调理剂的提取和使用来源，生物聚合物处理土壤的特性，以及他们对环境的关注。还对生物聚合物的整个Scopus数据库进行了初步搜索，以找出迄今为止与这些分子的其他应用相比，生物聚合物作为生物肥料受到了多少关注。对几个土壤质量指标进行了评价，包括土壤湿度，颜色,结构,孔隙度,堆积密度,温度,骨料稳定性，营养可用性，有机物,和微生物活动。还讨论了改善土壤质量的机制。
