Irrigation management included four leaching fractions (LF), i.e., accounting for 0, 15, 20, and 30% of applied excess water. The effects of four amounts of annual gypsum application, i.e. 0, 1.7, 2.6, and 3.4 t/ha, were also simulated....

Understanding the watershed﹕cale spatial distribution of soil salinity and its compositions is important for soil management. Here, we present the first study on the Manas River watershed in northwest China. In this study, we took soil samples in upper 20 cm of soil from 186 locations across ...
A new design and management system that introduces the concepts of drainage and no-drainage cycles is presented and applied to a hypothetical farm representative of the field conditions in the San Joaquin Valley of California over eight growing seasons. The objective is to reduce subsurface drainage...
HONGLIANG FANG,GAOHUAN LIU,MICHAEL KEARNEY - 《Environmental Management》 被引量: 180发表: 2005年 Reflectance spectroscopy for the assessment of soil salt content in soils of the Yellow River Delta of China There has been growing interest in the use of reflectance spectroscopy as a rapid and ine...
owing to inefficient operation of irrigation schemes and problems in farm water management, risk of soil salinity is a major threat to sustainable crop productivity in irrigated agriculture. While excess water application may cause rising of water table, it can also cause increase of soil salinity....
Review on Causes, Effects, and Management of Soil Salinity on Irrigated Rice Fields in Tanzania International Journal of Environmental & Rural DevelopmentMACHA, JIMMY FELIXMACHITO MIHARA
Additionally, examples are given which show that much of the apparent chaos observed in the spatial pattern of soil salinity in irrigated fields is man-induced and related to such management practices as irrigation, drainage, and tillage. 展开 关键词: salinity irrigation drainage management assessment...
In addition, we often develop transformations to soil spectral data when building models, such as smoothing, multiplicative scatter correction (MSC), and vector normalization (SNC). A number of different spectral transformations have been carried out when predicting soil organic matter, total nitrogen ...
