This paper reviews four aspects of land application of sewage sludge including agricultural application ,forest application,horticultural application and amending damaged soil.

Ecosystem Health Evaluation in Ecotone Between Agriculture and Animal Husbandry in Northern China Farmland: the case of WuChuan County;

Initial study on owner of farmland standardize construction engineering norm turns a management;

On questions about farmland soil moisture content monitoring-forecasting;

Assessment of soil environmental quality of cropland in Gaoyou area;

The effects of temperature and soil moisture on soil respiration in the cropland under elevated pCO_2;

A review on radiation use efficiency of the cropland;

Transfer function model to simulate nitrate leaching in soil from applied and indigenous nitrate under transient water flow Ⅱ. field application;

Based on the field data from the three plots of one hectare in Quzhou County on North China Plain,water drainage and nitrate leaching are calculated with a soil water balance model (SWB) and the dynamic process model (DPM).

Field margins were grouped into beetle banks, conservation headlands, grass margins, set-aside margins, sterile strips, flower margins and uncropped wildlife strips based on wild-life harboring in the field.

The treatments included woodlots,field margins,wheat/corn fields and vegetable fields with different cultivation measures.

It was concluded that biodiversity index and numbers of biological groups in field margins are higher than those in the related crop fields.
