The effects of urbanization on soil structure can be extensive. Infiltration of rain water through soils can be greatly reduced, plus the benefits of infiltration and biofiltration devices can be severely jeopardized. Our research group (along with others), have been studying disturbed urban soils for several decades, both in the laboratory and in the field. The effects of compaction on infiltr...

background and objectives: soybean (glycine max l.) is the most important oil crop having the largest area under cultivation in the world. every year, water stress causes great damages on crops in the world, particularly in iran with arid and semi-arid climate so application of materials such as zeolite in soil can reduce the adverse effects of water stress. however, the effect of zeolite in in...

in order to investigation some soil characteristics and filed age effects on flower and corm yield of saffron, an experiment was conducted as factorial based on complete randomized design with five replications in two regions of neyshabur during growing season 2009-2010. treatments were included different filed ages (2, 4 and 6 years) and two geographical regions (eshagh abad and soltan abad). ...

Abstract. Texture is a fundamental soil property for multiple applications in environmental and earth sciences. Knowing its spatial distribution allows better understanding of the response conditions to changes environment, such as land use. This paper describes technical development Colombia's first texture maps, obtained via ensemble national global digital mapping products. work compiles new...

Soil texture is an important environmental factor that influences the crop productivity of wheat (Triticum aestivum) because it provides all nutrients required for growth plants. The soil based on classified into four classes: silt, clay, sand, and loam. mineral particles was by United States Department Agriculture (USDA). According to USDA, loam have a size between sand (2.00–1.0 mm) silt (0.0...
