Effects of reduced tillage on soil surface properties affecting wind erosion in semiarid fallow lands of Central Aragón
In Central Aragón (NE Spain), where strong and dry winds are frequent all year round, fallow lands are susceptible to wind erosion due to insufficient crop residues on the surface and loose, finely divided soils by multiple tillage operations. Effects of conventional tillage (CT — mouldboard ploughing followed by a compacting roller) and reduced tillage (RT — chisel ploughing) on soil surface p...
متن کاملWind erosion measurement on fallow lands of Yazd-Ardakan plain, Iran
Wind erosion is a significant problem on 20 million ha of Iran, especially in central plains and coastal areas. Winderosion samplers, meteorological equipments and measurement procedure have been developed over the last twocenturies to measure the particles moving across the field in modes of creep, saltation and suspension. In recentresearch as the first technical measurement in Iran, wind ero...
متن کاملTillage Mulch Depth Effects during Fallow on Wheat Production and Wind Erosion Control Factors
Blowing dust from summer fallow is a major soil loss and air quality concern in winter wheat (Triricum aesrivum L.) production areas of the inland Pacific Northwest (PNW). The objective of our 3-yr onfarm study in a 286-mm precipitation zone in eastern Washington was to determine the effects of tillage mulch depth during fallow on surface soil roughness, residue retention, seed-zone water stora...

متن کاملWind tunnel experiments on the effects of tillage ridge features on wind erosion horizontal fluxes
In order to parameterize horizontal soil fluxes produced by wind over tillage ridges, eight-ridge configurations composed of sandy soil and exhibiting ridge heights to ridge spacing (RH/RS) ratios ranging from 0.18 to 0.38 were experimented in a wind tunnel. These experiments are used to develop a parameterization of the horizontal fluxes over tillage ridged surfaces based only on the geometric...
