Investigating Of Changes In Chemical Properties Of Soil Under Cultivation Of Different Age Classes Of Haloxylon-planted Areas In Zavvareh,Esfahan of Iran

By studying the relationship between plant - soil can be achieved to some of the characteristics of each of these characteristics for proper management and in accordance with ecological principles can be used. It can be due to changes in each of these factors, another factor changes in an appropriate level forecasting and to improve and develop ranges of thesechanges will be well-used. For the purpose this study was done to evaluate effect of Haloxylon plant species in different age s levels, on the chemical properties of soil in zavarehin Esfahan province. For this purpose, sampling was done as randomized-systematic in three Haloxylon-planted areas (8, 15 & 23 year ages) and one adjacent control area. Soil samplingwas taken in each control area in two-120m transects with 30m intervals at two depths (0-30 & 30-60 cm). Soil samples were investigated in the laboratory. After importing the data, inSPSS, ANOVA, and Duncan test were used. The result showed that, Haloxylon did not effect on the lime, gypsum, Ca, Mg, pH & N significantly, but there were significant effects on EC,P & K in Haloxylon-planted areas with different ages. Therefore, it can be concluded that,planting Haloxylon can make some changes in some chemical properties of soil.
