Assessing soil erosion in semi-arid area using Geographical Information Systems

Effects of stubble and mulching on soil erosion by wind in semi-arid China

Soil erosion is a growing challenge for agricultural production in Northern China. To explore the effect of variation in stubble height and mulching biomass on soil erosion caused by wind, we conducted a field experiment using a quadratic rotation combination design. Results showed that the quantity of straw mulch was the dominant factor affecting soil erosion, and stubble height was of seconda...

Controls on Patterns of Soil Moisture in Arid and Semi-arid Systems

Wind and Water Erosion in Semi-arid Ecosystems

Soil erosion is an important process in dryland ecosystems, yet measurements and comparisons of wind and water erosion within and among such ecosystems are lacking. Here we compare wind erosion and transport field measurements with water erosion and transport from rainfall-simulation for three different semi-arid ecosystems: a shrubland near Carlsbad, New Mexico; a grassland near Denver, Colora...

Assessing the Vulnerability of the Land Using the IDI Combination Model in Arid and Semi arid Regions (Khorasan Razavi)

Land vulnerability one of the major global challenges as an objective case of degradation of arid, semi-arid and semi-humid ecosystems caused by natural processes and human activities. However, in order to assess the vulnerability of the land, it is necessary to know exactly the degree of tolerance of ecosystems and the use of indigenous knowledge systems to external conditions.The present stud...

Mobility of Indaziflam Influenced by Soil Properties in a Semi-Arid Area

Indaziflam, a broad-spectrum, pre-emergence herbicide was the focus of a field investigation conducted after the identification of sporadic injury symptoms on the pecan trees a few months after the application. The study was conducted in two pecan orchards located in southern New Mexico, USA, and southeastern Arizona, USA. The objectives of this study were to evaluate the occurrence and distrib...
