摘要
Abstract
The exploitation of sludge soil dredged area as an industry developed rapidly these years. However, the problem of low economic benefit was still prominent. The study on soil primary nutrients and physical and chemical properties in sludge soil dredged area of The Yellow River in Jinan was carried out and the results showed that in range of more than 40 kilometers, the texture, fertility, water content of sludge soil dredged area were far below those of farmland. The thickness of overburden was less than 45 cm, and the average content of organic matter, hydrolysable nitrogen, available phosphorus, available potassium were 6.2, 18.13, 2.05, 119.95 mg/kg respectively with the general lack of microelements. Hence, the soil was in poor quality. In order to improve the soil quality, some measures such as thickening the loam soil layer and increasing soil fertility must be done through biological and engineering methods.关键词
