No-till acreage has increased in recent years, but many farmers alternate no-till with other tillage practices, limiting public and private benefits from sustained no-till adoption. Revealed preference data are used in an ordered logit regression analysis to determine the effect of soil characteristics, climate, regions, farm characteristics, and producer demographics on producers’ choices to u...

Soil erosion in vineyards has to be considered as an environmental concern as it depletes soil fertility and produces damages in the fields and downstream. High soil and water losses decrease soil quality, and subsequently, can reduce the quality of the grapes and wine. However, in specialized journals of viticulture and enology, soil erosion studies are not present. This paper surveys the soil...

The reclamation area on ex-coal mining land is very vulnerable to erosion. Soil vulnerability comes from the physical properties of soil, ease with which it erodes, and topographical conditions. Erosion occurs in open areas little overgrown vegetation. However, this condition course a fundamental consideration factors that influence This type research descriptive quantitative research, obtained...

Runoff and interrill erosion were measured on three composted organics applied at 5-cm and 10-cm depths, a topsoil treatment (15-cm application), and the existing soil on a highway embankment with a 3 to 1 slope. Treatments were tested immediately after preparation and six weeks later to allow for the vegetative cover crop to grow. Rainfall simulations were conducted at an average intensity of ...

The analysis demonstrated that the sand con...

introduction soil losses and erosion is one of the main causes of fertility decreasing, sedimentation in river cannels and irrigation canals, decreasing of storage capacity in dams, increasing of floods frequency, environmental pollution and it prevents from stable development. more than 70% of iran land is covered with arid and semi-arid areas. soil erosion as one of the main causes of soil de...

The USLE and the RUSLE are two common erosion prediction models that used worldwide, soil erodibility (K-factor) is one parameter to calculate them. objectives of this study were investigate variability soil-erodibility factors under different soil-texture classes evaluate efficiency diffuse reflectance spectroscopy (DRS) in near-infrared range at predicting K-factors using a partial least squa...
