Abstract

This study was to analyze the efficiency (E) of traps in holding suspended soil particles that cause dust, environmental and agricultural problems by wind erosion in NWCZ, Egypt. These vertical and passive sediment traps with different design in rotary and fixed reservoir box and different methods of measured soil loss. Rotary Distance (RD), Fixed Distance (FD), Rotary Point (RP) and Fixed Point (FP) traps were compared with traditional trap Big Spring Number Eight (BSNE). The variation between traps’ efficiency as a function of height was significantly (P≤0.05) and was as follow: RD, FD, RP, and FP more increase than BSNE. The performance of the trap types as an efficiency of suspension particles (assumed to possess E=1 for suspended particle sizes) was as follow RD> FD> RP> FP> BSNE; 99%, 98%, 88%, 85%, 65% respectively. The efficiency of traps in suspension particles size (<45, 45- 63 and >100 µm) were significant (P ≤ 0.05) and the best efficient were RD and FD. Therefore, RD and FD traps have direct methods for measuring soil loss by wind erosion and have the most acceptable, accurate, fastest and easiest in soil particle analyzed and therefore the most effective way to discriminate suspension particles.

Highlights

Aeolian soil transport caused by wind erosion [1]
According to [9], 430 million ha of drylands, which comprise 40% of earth’s surface are vulnerable to wind erosion. [10] reported that wind erosion in the NWCZ of Egypt may be a major problem in agriculture development and environment because sandy soils texture
There were different between eroded soil weight at sampler from15 to 100 cm height due to the particle movement type in each height [21]

Summary

Introduction

The wind erosion is that the major initiator of emission of soil particles worldwide which can cause serious agricultural and environmental problems, such as pollution [2], [3], [4] and [5]. [10] reported that wind erosion in the NWCZ of Egypt may be a major problem in agriculture development and environment because sandy soils texture. Several studies concern about the saltation particles movement because it most vital parameter within the amount dust transported They concern to calculate the soil dust horizontal mass flux (HMF) [15], [14] and [16].
