soil granular meaning in English

粒状土壤

The results are summarized below : 1 ) study on soil science indicates that soil granular structure is the focus adjuster for soil fertility and it affects the space , water - grasp , aeration and anti - erosion of soil . and the percentage of aggregate is one of the key index that decides the speed and extent of soil erosion , hardening and degeneration because the soil degeneration will first lead to the disappearance of crumb - structure . so it is very important that the physical course and character of soil in different land use pattern are realized
现将主要结果摘要如下： l 、士壤学研究表明，团粒结构是土壤肥力的中心调节器，影响着土壤的空隙性、持水性、通透性和抗蚀性；任何土壤的退化首先将表现出团粒结构的消失；团聚体百分比是决定土壤侵蚀、板结等物理过程速度和幅度的关键指标之一，了解不同土地利用和土壤管理方式的物理过程和性质相当重要。
