Physiology of Stressed Crops, Vol. 2: Nutrient RelationsThis volume covers various aspects of nutrient (deficiency or toxicity) stress in general, and the effects of stress factors like soil acidity, soil salinity, allelochemicals, soil compaction, drought, water logging, atmospheric humidity, low temperature and freezing, high temperature (heat), solar radiation (low or high intensity and UV light) and air pollution have been discussed. The nutrient stress caused by parasitic weeds has also been discussed separately. Such a study will greatly help in avoiding the stress-induced problems of nutrient unavailability, fixation, excessive availability, uptake, transport, mineralization symbiotic fixation, and removal etc. and help in growing better crops in problem soils and/or problematic environments. |
