Condition and trend of a depression-type habitat In rainfed desert rangelands of Qatar In response to fertilizer application
MetadataShow full item record
Characteristics of a rainfed depression-type habitat in desert ranges, and its response to fertilizer application were studied. A single fertilizer application at a rate of 75 Kg ha1 prior to the rainy season improved range productivity by enhancing forage above-ground vigour. This enhanced vigour was manifested by a two-fold increase in the total grazable phytomass, and was reflected in increased forage nutritional value. Consequent accumulation of a greater amount of plant community litter represented a favourable implication of range fertilization. The recommended fertilizer application did not affect the vegetative composition of the studied community, and hence did not impose ecological unfavourable impact.
