[Adaptability of to sewage sludge and its characteristics of nutrient and heavy metal uptake and accumulation].

, an important fast-growing economic tree species in China, has the advantages of strong adaptability, high-biomass, and high bioconcentration of heavy metals. Sewage sludge contains a great deal of nutrients and heavy metals. Planting with sewage sludge can achieve the goals of sewage sludge remediation as well as resources production of .

Effects of sewage sludge and other wastes application on the growth and element uptake of in abandoned rare-earth mine soil.

The wastes such as sewage sludge (SS) can be used to amend soil of abandoned rare-earth mine land (ARL). The energy plant could be used as a pioneer tree species in the ARL. In a pot experiment to address the responses of growth and element uptake of , three treatments were established: adding SS to the soil of ARL (T), adding SS and bagasse to the soil of ARL (T), adding SS, bagasse and passivator to the soil of ARL (T), with the untreated soil of the ARL as the control (CK).

[Effects of sewage sludge compost on the growth and element uptake of Neolamarckia cadamba seedlings].

Sewage sludge compost (SSC) is rich in organic matter and nutrient elements indispensable to plant growth. Utilizing SSC as seedling growing substrate is generally recognized as a new ecological method for utilization of sewage sludge. We investigated impacts of SSC treatments including 0% (CK), 25% (T), 50% (T), 75% (T), and 100% (T) on the growth and nutrient uptake of Neolamarckia cadamba seedlings in a 7-month pot experiment.

[Heavy metal tolerance of Miscanthus plants and their phytoremediation potential in abandoned mine land].

Miscanthus has been recognized as promising candidate for phytoremediation in abandoned mine land, because of its high tolerance to heavy metals and bioenergy potential. Miscanthus has been reported tolerant to several heavy metal elements. However, it has not been recognized as hyperaccumulator for these elements.

[Effects of simulated nitrogen deposition on soil acid phosphomonoesterase activity and soil available phosphorus content in subtropical forests in Dinghushan Mountain].

An in situ field experiment was conducted to study the effects of simulated nitrogen (N) deposition on soil acid phosphomonoesterase activity (APA) and soil available phosphorous (AP) content in Pinus massoniana forest (PF), coniferous and broad-leaved mixed forest (MF), and monsoon evergreen broad-leaved forest (MEBF) in Dinghushan Mountain. In PF and MF, three treatments were installed, i.e.

[Soil organic carbon density of Eucalyptus plantations in Guangdong province of China and related affecting factors].

Soil samples were collected from the Eucalyptus plantations in the north, east, and west Guangdong and Pearl River Delta region to study their organic carbon content and density, and the main factors affecting the organic carbon density. In the plantations, the soil organic carbon content and density in A and B horizons were significantly different, with the values of (23.94 +/- 2.

[Reducing nutrients loss by plastic film covering chemical fertilizers].

With the low utilization rate of fertilizers by crop and the growing amount of fertilizer usage,the agricultural non-point source pollution in China is becoming more and more serious. The field experiments planting corns were conducted, in which the applied chemical fertilizers were recovered with plastic film to realize the separation of fertilizers from rain water. In the experiments, the influences of different fertilizing treatments on the growing and production of sweet corn were observed.

Impact of fertilization on chestnut growth, N and P concentrations in runoff water on degraded slope land in South China.

Growing fruit trees on the slopes of rolling hills in South China was causing serious environmental problems because of heavy application of chemical fertilizers and soil erosion. Suitable sources of fertilizers and proper rates of applications were of key importance to both crop yields and environmental protection. In this article, the impact of four fertilizers, i.

[Leaching characteristics of nitrogen and phosphorus in inorganic compound fertilizer from latosolic red soil in south China].

A soil column experiment was conducted to investigate the leaching characteristics of nitrogen and phosphorus in inorganic compound fertilizer from latosolic red soil in South China. The results revealed that the leaching loss of soil total nitrogen (TN), NH4+ -N and NO3-N was increased with increasing application rate of inorganic compound fertilizer, and 36.8%-49.
