【Abstract】 A pot experiment with Brassica Parachinensis Bailey, Maize and a field experiment with Maize were carried out to prove the effect of a new type of granulated soil amendment from paper mill sludge compost. The result suggested that the soil amendment not only promotes the growth of this two crops, increases the nutrient absorption of nitrogen and phosphorus, but also decreases bulk density of soil, enhances availability of soil phosphorus, and protects nitrogen nutrient to a certain extent. What’s more, using paper mill sludge soil amendment will not pollute soil and farm products.更多还原
