Abstract: (3667 Views)

Due to rangeland ecosystems management role on nutrient, the present study was conducted to investigate the relationship between soil and plant nutrients in different grazing management and their changes in the Laseoureh rangland, Lorestan Province. In doing so, the study area was obtained and grazing treatments including grazing, short-term grazing exclosure (one year exclusion) and mid-term grazing exclosure (five years exclusion) was determined by field surveying. Then, the sampling was done by two transects (100m) and 10 plots (1m²) via a randomly systematic method. Sampling was later done based on canopy cover percentage in the plots after determination of dominant species. Also, soil sampling was done according to mean root depth in each plot under dominant species. Next, plant and soil properties such as nitrogen, phosphorus and potassium were also determined in laboratory. Finally, the data were analyzed using the SPSS 20 software. The statistical processing was conducted by variance analysis and Tukey-test. The results showed that rangeland species and grazing managements has a significant effect on all nutrient elements (P≤0.05). However, the interaction effect of rangeland species and grazing managements was merely significant on P (P≤0.05) . Likewise, the elements significantly increased from grazing treatment to one year exclosure and 5 years exclosure. However, the effect of five years exclosure increased soil nutrients. Notably, short-term exclosure had no significant difference with grazing treatment.
