Soil organic matter is the product of microbial decomposition of plant and animal residues. 土壤有机质(SOM)是微生物分解植物和动物残体的产物。
The results showed that MDS included soil organic matter content, available phosphorus, invertase activity, and fungi. 结果表明,研究区土壤质量评价指标最小数据集为有机质、速效磷、蔗糖酶和真菌。
A major portion of the soil organic matter is derived from the added and residual vegetative material. 加进去的和残留下来的植物物质则是土壤有机质(SOM)的主要来源。
Finally, the relativity between soil organic matter and every kind of available microelements was conducted for preliminary analysis and discussion. 最后,对土壤有机质(SOM)和各种有效态微量元素之间的相关性进行了初步分析和讨论。
Spring with moss, so the soil organic matter, is it place moist fertile. 泉水中附有苔藓之类的有机物,因而土壤较它处润泽肥沃。
