ELTAIF, N. I. y GHARAIBEH, M. A.. Application of a mathematical model to predict and reduce wind erosion in non-protected arid lands. Rev. Chapingo ser. cienc. for. ambient [online]. 2011, vol.17, n.spe, pp.195-206. ISSN 2007-4018. https://doi.org/10.5154/r.rchscfa.2010.08.061.
Soil wind erosion is one of the most serious land degradation problems in the arid and semi-arid regions of the world. Calculation of the potential erosion for study area averaged 70.2 Mg·ha-1·year1. In an attempt was made to reduce wind erosion using a mathematical model. Results showed that applying short predetermined succeeding lengths reduced wind erosion greatly but not fairly enough. Wind erosion tends to decrease with decreasing field distance; however the tolerable level of soil loss was not achieved by applying a short field length of 50 m and a ridge value of 0.5. The used model helps to draw some preliminary conclusions about the possible conservation practices (vegetative cover) to mitigate wind erosion. Calculations indicated that using 250 to 500 kg ha-1 of plant residues seems to be adequate to diminish soil loss to a tolerable level (~ 2 Mg·ha-1) irrespective of K and L values.
