美国阿拉巴马州的广大地区因土质过硬而成了寸草不生和不毛之地。该州土壤专家詹姆斯·爱德沃兹,最近设计出一种用粉碎的废报纸改造土壤的好方法。由于废报纸在土中不会很快腐烂变质,爱德沃兹采用纸屑加鸡粪(比例为:纸屑40%,鸡粪10%,原土壤50%)的混合法。试验证实,纸屑在鸡粪中的基肥细菌的作用下迅速变质,土壤在3个月内即变得松软异常。据悉,这种土壤不仅适合长牧草,而且
The vast area of the United States, Alabama, has become inhospitable and barren because of its strong soil. James Edwards, a soil expert in the state, recently devised a good way to rebuild the soil with shredded waste paper. As waste newspapers do not decay quickly in the soil, Edwards uses a mixture of paper dust and chicken manure (40% confetti, 10% chicken manure, 50% original soil). Tests confirmed that paper scraps of chicken manure in the rapid deterioration of the role of bacteria, the soil becomes loose and abnormal within 3 months. It is reported that this soil is not only suitable for long grass, but also
