The problem in this study is that the selection of avocado cultivation land still uses method and does not use a computer-based system to choose priorities. Because it has used priorities, purpose build by implementing decision support for selecting using Additive Ratio Assessment (ARAS) method. criteria parameters alternative consist temperature, rainfall, dry month length, soil texture, drain...

Cultivated land quality is an essential agricultural resource and production element. To increase cultivated in a targeted way, it crucial to understand the features of regional elements that constrain its quality. In order diagnose restriction factors affecting improvement grades conduct quantitative analysis factors, index model was used this study analyze distribution characteristics East An...

This study used morphometric techniques to generate new information describing the evolution and hydrogeological behaviour of Limpopo River Basin in Botswana, based on analysis drainage surface features, form, size. Drainage basins provide basic their evolution, which, when quantified, yield interaction between tectonics, climatic, processes. networks were extracted from Shuttle Radar Topograph...

Geographic Information Systems and remote sensing, have proved to be efficient tools in delineation of drainage pattern different geometric methodology geomorphologic, watershed management even GIS has been widely used several flood management, environmental applications. The river Beki with an area 19,354.35 sq.km2 originates at Himalayan glacier (Kula Kangri Bhutan) 26.18° N latitudes 90.53° ...

The soil profile samples that are present in upper slopes of the Palamaner agricultural division evaluated to know production potential study area. soils have moderate slope and affected by erosion. Besides, excessive drainage limitation. Geologically, developed on quartz-migmatite gneiss complex. All studied for morphological, physico-chemical chemical properties. results shown that, slightly ...

concerns about nitrate pollution in groundwater and downstream systems cause development of surface water management system to reduce losses of agricultural drainage water nitrate in subsurface drainage using subsurface irrigation from existing drainage lines, drainage water during the growing season and out of season is controlled. the overall objective of this study was to evaluate the effect...

Agricultural intensification was linked to streamwater pollution in a case study watershed using GIS and nutrient budgeting techniques. The results showed that surplus nitrogen applications from fertilizers and manure averaged 120 kg ha−1 yr−1. In some parts of the watershed surplus applications exceeded 300 kg ha−1 yr−1. A consistent increase in pig and chicken numbers (59 and 165% increase be...

This paper proposes a decision treemodel for specifying the importance of 21 factors causing the landslides in a wide area of Penang Island, Malaysia. These factors are vegetation cover, distance from the fault line, slope angle, cross curvature, slope aspect, distance from road, geology, diagonal length, longitude curvature, rugosity, plan curvature, elevation, rain perception, soil texture, s...

BACKGROUND With myriad geospatial datasets now available for terrain information extraction and particularly streamline demarcation, there arises questions regarding the scale, accuracy and sensitivity of the initial dataset from which these aspects are derived, as they influence all other parameters computed subsequently. In this study, digital elevation models (DEM) derived from Advanced Spac...

BACKGROUND Key climatic factors influencing the transport of pesticides to drains and to depth were identified. Climatic characteristics such as the timing of rainfall in relation to pesticide application may be more critical than average annual temperature and rainfall. The fate of three pesticides was simulated in nine contrasting soil types for two seasons, five application dates and six syn...
