This damage reduces survival, growth, leaf area, quanity and quality of plant yield, delays maturity, and contributes to plant disease transmission. Future challenges in quantifying the effect of wind and sandblast damages under field conditions, effect of burial and/or removal from around roots, and measuring the energy of particle impact are discussed. Future challenges to research on wind damage effects are: quantifying plant sandblast damage under field conditions, including burial or removal of soil from around roots. Improved equipment are also needed to measure the energy of windblown particle impacts. Technical Abstract: Wind Erosion is a major problem on agricultural lands in much of North Africa, the Near East, parts of Asia, Australia, southern South America, and portions of North America. Particles moving in wind stream damage plants by impact, burial, and exposure of plant roots. Reported effects of wind and sandblast damage are: reduced dry weight, leaf area, plant height, ,survival, photosynthesis, and quality and quantity of yield. Additional effects include increased respiration, delayed maturity, plant disease transmission, morphological, and anatomical changes. Future challenges to research on wind damage effects are: quantifying plant sandblast damage under field conditions, while including additonal factors such as burial or removal of soil from around roots. Improved transducers are also needed for measuring the energy of windblown particle impacts. |
