“…The results revealed almost seven times higher efficiencies for BEST than MWAC for the particle size of < 100 µm, and the efficiency of BEST for < 100 µm was 75-90% while MWAC resulted in efficiencies about 10-20%. However, in previous studies, particularly with sand of relatively larger particle sizes, MWAC had much better efficiencies than those found by Basaran et al (2011).…”

“…The Basaran and Erpul Sediment Trap (BEST), designed based on cyclone technology, suggests a promising result in trapping sand and dust size particles during wind tunnel tests (Basaran et al 2011). Aerodynamic structure and inside flow characteristics of BEST could significantly reduce its inlet static pressures, which were denoted as a main cause of lower efficiencies in passive traps, and the reduced inlet static pressures could remarkably provide a higher trap efficiency to catch both saltating and suspending particles (Cornelis & Gabriels 2003).…”

“…The relationship between static pressure and efficiency was shown by wind tunnel experiments. Basaran et al (2011) measured the efficiencies of the BEST and MWAC catchers for four different sand particle sizes (400-500, 200-300, 100-200, and < 100 µm) at four different wind speeds (12, 13, 14, and 15 m/s). The results revealed almost seven times higher efficiencies for BEST than MWAC for the particle size of < 100 µm, and the efficiency of BEST for < 100 µm was 75-90% while MWAC resulted in efficiencies about 10-20%.…”

Field measurement of wind erosion is still a great challenge for researchers. In this study, field performance of a newly designed sediment trap BEST (Basaran and Erpul Sediment Trap) was evaluated for the first time and compared with the commonly used Modified Wilson and Cook (MWAC) traps. Experiments were carried out at the Karapinar Research Station of Konya Soil and Water Resources Institute over the 50 × 50 m tilled sandy loam plot. Three wind erosion events occurred during the experiments. A small amount of sediment was trapped by the MWAC traps only at 0.20 m in all three events, and there were not sufficient sediment measurements at the catch heights to obtain vertical mass flux profiles. On the other hand, BEST was able to catch sufficient amount of sediment at each trap height to calculate soil losses from the experimental fields. Besides, an analysis for particle size characteristics by electron microscopy imagery indicated that almost all of the sediment particles trapped by BEST at any height above 0.60 m were smaller than 100 mm. Hereby, during three erosive wind events a better performance of BEST than of MWAC at comparable catch heights was verified.

“…Thus, the plot size was 2 km 2 (2 × 1 km). In each plot, the sediment traps BEST (Figure 3) (Basaran et al 2011) were fixed into the field with anchorage bars along a linear route and perpendicularly to prevailing wind direction. The cyclone BEST has a plastic body produced by a plastic injection system.…”

Başaran M., Uzun O., Kaplan S., Görmez F., Erpul G. (2017): Tillage-induced wind erosion in semi-arid fallow lands of Central Anatolia, Turkey. Soil & Water Res., 12: 144−151.Wind erosion and resultant dust emissions create significant risks for land degradation and ecosystem health in arid and semi-arid regions. In these regions, fallowing constitutes a major component of conventional agriculture. The present study was conducted to determine wind erosion quantities and agricultural activity-induced mass transport from fallow lands and to assess the correlations of mass transport with climate and soil characteristics. Experiments were conducted over the fallow lands of two adjacent agricultural enterprises (Altinova and Gözlü, Turkey). Sediment flux was measured with passive traps in wet and dry seasons (Q tWET and Q tDRY ). Mass transport in wet and dry seasons was respectively measured as 11.38 and 11.40 kg/ha in Altinova and as 31.61 and 19.71 kg/ha in Gözlü. Both the differences between mass transport of the enterprises and the differences between Q tWET and Q tDRY of each enterprise were found to be significant (P < 0.05). Pearson's correlation analysis for the correlations of mass transport with soil characteristics revealed significant correlations with electrical conductivity and soil lime content (r = 0.721 and -0.635) (P < 0.05). Total mass transport from the fallow lands of both enterprises throughout a 7-month period of measurement was estimated at 600 t. Based on current findings it was concluded that fallowing should be abandoned and sustainable soil and land management practices from conventional agriculture like minimum tillage or crop rotations should be introduced.

Dressing seeds with pesticides to control pests is a widespread practice with important advantages. Recent incidents of bee losses, however, have directed attention to the emission of abraded pesticide-coated seed particles to the environment during sowing. This phenomenon of drift of pesticide dust can lead to pesticide contamination of air, water and other natural resources in crop-growing areas. This review article presents the state of the art of the phenomenon of dust emission and drift from pesticide seed dressing during sowing and its consequences. Firstly, pesticide seed treatment is defined and its pros and cons are set out, with the focus on dust, dust emission and dust drift from pesticide-coated seed. The factors affecting emission of pesticide dust (e.g. seed treatment quality, seed drilling technology and environmental conditions) are considered, along with its possible effects. The measuring techniques and protocols and models currently in use for calculating the behaviour of dust are reviewed, together with their features and limitations. Finally, possible mitigation measures are discussed, such as improving the seed quality and the use of modified seed drilling technology, and an overview of regulations and stewardship activities is given.
