Abstract:

Plant litter is an important factor for soil conservation and sustainability that could modify soil chemical properties and increase the plant biomass production. The aim of this research was to compare plant litter chemical composition and its effects on soil properties in three species including Hordeum bulbosum, Poa bulbosa, Bromus tectorum. First, soil samples were taken in the depth of 0-30 cm and litter samples were collected from soil surface based on a random-systemic method using three 200m transects. Then, samples of dried plants of current and previous years were taken from 1 m2 plots. The soil samples under the plants and bare soil (as control) were also taken at the depth of 0-30 cm. Finally, the chemical composition of litter and physical and chemical properties of soils were analyzed. Results showed significant differences between species in terms of potassium (K), carbon (C), nitrogen (N) and carbon to nitrogen (C/N) ratio  (P

Monthly variation of production of key range species in central arid rangeland, Case study: Saveh-Markazi Province, Iran

     Forage production of rangelands differs during different times of grazing season and in the same month of different years. In range management projects, grazing capacity calculated once during the grazing season, which coincides with the maximum production of rangeland species. This may cause more livestock entry into the rangeland during the grazing season, leading to more degradation. Th...
