Row-crop agriculture is under pressure to reduce sediment and nutrient losses to surface water resources by practicing less tillage and more precise application and placement of nutrients. Field studies started in 1997 were conducted through 2002 on very low to low P-testing (3 to 5 ppm Bray P1) and medium to high-P testing (11 to 19 ppm Bray P1) sites of a Nicollet-Webster clay loam complex at...

This study evaluated the effectiveness of soils with different texture and depth to treat fecal bacteria eluted from a house-hold septic effluent. The assessments were accomplished by leaching undisturbed soil monoliths of 30, 45, and 60cm thickness and 25cm in diameter, representing the four different textural groups and hydraulic loadings recommended by the Kentucky Health Department, with do...

As salt-affected soils (SAS) are widespread in Hungary, several classification schemes have been proposed for them during the last centuries. These soils are inherently related to soil salinity/sodicity/alkalinity and the consequential hydrophysical properties of the soil; therefore, they present severe abiotic stress for plants and animals. Based on the approach of the assessment of the soil, ...

Soil erosion/sedimentation is an immense problem that has threatened water resources development in the Nile river basin, particularly in the Eastern Nile (Ethiopia, Sudan and Egypt). An insight into soil erosion/sedimentation mechanisms and mitigation methods plays an imperative role for the sustainable water resources development in the region. This paper presents daily sediment yield simulat...

Established and developed over the last 30 years, the Land Information System (LandIS) holds significant national soil-environmental datasets collected primarily by the Soil Survey of England and Wales between 1939 and 1987, and latterly by the National Soil Resources Institute (NSRI) at Cranfield University. LandIS data are in widespread use through systems of architecture designed to facilita...

Atrazine, a herbicide widely used in corn production, is frequently detected as pesticide in water resources. In this research, four agricultural fields with a long history of atrazine application in Shiraz and its vicinity in Fars province of Iran, have been studied to determine the fate of atrazine through the passage of time. These four farms were cultivated under a crop rotation (corn-wheat...
