This study aims to determine the accuracy level at which different forms of land degradation can be mapped from medium-resolution satellite data, and to assess how accurately degraded land can be detected from multi-temporal satellite images. Land degradation in the form of salinization and waterlogging in Tongyu County, western Jilin Province of Northeast China was mapped from Landsat TM and A...
Management of irrigation and fertilization in greenhouses, if not done correctly, can cause soil salinization. The use water treated with very low-frequency electromagnetic resonance fields (WVLF) reduce salinization effects on the photosynthetic biometric systems. Thus, purpose research to evaluate metabolism photosynthesis impact WVLF cultivation tomato crops subjected different levels fertig...
The article presents the analysis results on study of physical-mechanical properties soils in Uzbekistan and experimental studies influence parameters rational geometric shape working tools quality soil tillage while reducing energy costs. It has been established that moisture hardness periods basic pre-sowing differ significantly according to weather conditions, agrophonous background, sowing ...
Reliable and real-time information on soil and crop properties is important for the development of management practices in accordance with the requirements of a specific soil and crop within individual field units. This is particularly the case in salt-affected agricultural landscape where managing the spatial variability of soil salinity is essential to minimize salinization and maximize crop ...
abstract poultry manure contains considerable nutrients and its application to agricultural land may boost soil fertility. in order to study the effects of poultry manure and its incorporation method with soil on soil chemical properties, a field experiment was conducted at the ecological research center of zagroos, 30 kms from northeastern of khorramabad for two consecutive years (2004 and 200...
Global climate change projections suggest an increasing frequency of droughts and extreme rain events in the steppes of the Eurasian region. Using the eddy covariance method, we measured carbon and water balances of a meadow steppe ecosystem in Northeast China during 2 years which had contrasting precipitation patterns in spring seasons in 2007 and 2008. The meadow steppe sequestrated only 64Ð2...
Rice is a monocot gramineous crop, and one of the most important staple foods. Rice is considered a model species for most gramineous crops. Extensive research on rice has provided critical guidance for other crops, such as maize and wheat. In recent years, climate change and exacerbated soil degradation have resulted in a variety of abiotic stresses, such as greenhouse effects, lower temperatu...
