Abstract

Herbaceous plants recognition of diversity in the management of pastures and forests, and all the natural sciences, is used. In this study, to assess the operating effectiveness of organic matter, NPK, EC and pH on species diversity pastures, a 118 square meters plot, over 24 transects in different geographical directions in the watershed Qarootag Gilangharb district, in the province Kermanshah was implemented. In each plot, the number of grass species to species, altitude, and in the center of the plot of the depth of 30 cm, according to plant root penetration, soil samples were taken and notes. The results showed that the nitrogen, potassium and organic matter and diversity and uniformity, a positive association was found that 95% did not make sense. The results of the correlation between phosphorus and Simpson diversity index, 95% were positive and significant. Between the EC, pH and altitude, there was a negative correlation with diversity, it is not statistically significant.
