Physiological plant disorder Physiological plant disorder Physiological plant disorders are caused by non-pathological conditions such as poor light, adverse weather, water-logging, phytotoxic compounds or a lack of nutrients, and affect the functioning of the plant system. Physiological disorders are distinguished from plant diseases caused by pathogens, such as a virus or fungus. While the symptoms of physiological disorders may appear disease-like, they can usually be prevented by altering environmental conditions. However, once a plant shows symptoms of a physiological disorder it is likely that, that season’s growth or yield will be reduced. Diagnosis of the cause of a physiological disorder (or disease) can
Natural stress wind starts to blow the soil around, there is nothing to stop the process. The only chance for the soil to stay in place is if the wind doesn’t blow. This is usually not an option. Plant growth in windblown areas is very limited. Because the soil is constantly moving, there is no opportunity for plants to develop a root system. Soil that blows a lot usually is very dry also. This leaves little nutrients to promote plant growth. Farmland is typically very susceptible to wind erosion. Most farmers do not plant cover crops during the seasons when their main
