Since land resource database development in 1987/1988, a large amount of digital data in spatial, tabular and metadata format has been collected and generated. There are some application softwares of soil database to manage such a large amount of data, i.e.: Side & Horizon (SHDE4), Soil Sample Analysis (SSA), and Land Unit in dbf file, while Site and Horizon is in DataEase formats. The database...

Urban and peri-urban agriculture is becoming increasingly important as a source of income and food for the urban population in South Africa. This study was prompted by concerns of city authorities that soil compaction in horticultural fields that used conventional tillage practices with tractors was, not only limiting the performance of fruit and vegetable crops, but also affecting the quality ...

The utilization of sewage in agriculture has lately been receiving increasing attention in many countries. The question is especially important in a country with limited water resources like Israel where insufficient rainfall must be supplemented by irrigation. In order to evaluate the public health hazard involved, it is necessary, among other things, to obtain information on the survival of e...

Understanding interspecific interactions is key to explaining and modelling community development and associated ecosystem function. Most interactions research has focused on pairwise combinations, overlooking the complexity of multispecies communities. This study investigated three-way interactions between saprotrophic fungi in wood and across soil, and indicated that pairwise combinations are...

Soil food web structure and function is primarily determined by the major basal resources, which are living plant tissue, root exudates and dead organic matter. A field experiment was performed to disentangle the interlinkage of the root-and detritus-based soil food chains. An arable site was cropped either with maize, amended with maize shoot litter or remained bare soil, representing food web...

Field experiments were carried out in Huantai County from 2006 to 2008 to evaluate the effects of different nitrogen (N) fertilization and irrigation management practices on water leakage and nitrate leaching in the dominant wheat–maize rotation system in the North China Plain (NCP). Two N fertilization (NF1, the traditional one; NF2, fertilization based on soil testing) and two irrigation (IR1...

ScanSAR systems such as ENVISATs ASAR Global Mode allow monitoring of dynamic processes at medium resolution (1km). Hence they are especially useful for monitoring hydrologic processes such as soil moisture and inundation dynamics. Within the ESA DUE Tiger Innovator project SHARE (Soil Moisture for Hydrometeorological Applications) an operational monitoring scheme has been developed. As part of...

Living plant diversity (excluding the litter issue) may affect below-ground properties and processes, which is critical to obtaining an integrated biodiversity-ecosystem functioning theory. However, related patterns and underlying mechanisms have rarely been examined, especially lacking long-term evidence. We conducted a factorial crossed sample survey to examine the effects of plant diversity ...

desertification relates to the both the process and end state of drylands degradation. salinization and alkalinization are two indicators of soil degradation in arid and semi-arid regions. the main objectives of this research is monitoring of soil salinity using high spectral and spatial resolution of remote sensing to assess desertification in the marvast plain, yazd province. two images of te...

Conventional water resources of good quality are scarce especially in arid and semiarid regions. The salinization of soils and water places is a substantial constraint of crop productivity. The mixed application of fresh water along with seawater is becoming a common practice by the farmers near sea sides in the developing countries. Seawaters contain beneficial nutrients that can be useful for...
