据农业研究局的一位科学家报道,用作家畜饲草而种植的一种杂交禾草同时也能起到土壤改良者的作用。这种杂交禾草能够帮助改良西部数百万英亩含盐量很高的土壤。聚集在土壤中的盐分(钠盐)在土壤表面形成一个硬壳,妨碍作物生长。但是根据爱达荷州Kimbetly的土壤学家Charles Robbins介绍,高粱和苏丹草的杂交种可以在土壤中释放大量的二氧化碳,这些二氧化碳可以把土壤中的盐分游离出来,然后通过降水或灌溉把盐分从土壤中排出。
According to a scientist at the Agricultural Research Service, a hybrid grass grown for livestock forage can also function as a soil conditioner. This hybrid grass helps to improve millions of acres of salt-rich soils in the west. Salts (sodium salts) that accumulate in the soil form a hard shell on the soil surface, hindering crop growth. However, according to Charles Robbins, a soil scientist at Kimbetly, Idaho, sorghum and sudangrass hybrids release large amounts of carbon dioxide in the soil that releases salt from the soil and then removes salt from precipitation or irrigation from Excreted in the soil.
