Soil microbial respiration, as an important soil factor, is high sensitivity to land use changes. Soil conditions is changed by agricultural activities, particularly plowing. It increases organic material decomposition and microbial respiration. The effect of cultivation type on microbial respiration (MR) and some other soil parameters in land use change processes from natural rangeland to agriculture is the scope of the study. Therefore, three land uses were selected, viz. one natural rangeland, two orchards, two pea-lands plus two wheat-lands. Forty-two soil samples were collected through a random-systematically design within a 0-25 cm soil depth. The results of one-way ANOVA analysis showed that the highest value of MR was related to orchard with average of 0.63 mg co2 per day and the lowest values to wheat-land, rangeland and pea-land with average of 0.4, 0.3 and 0.3 mg co2 per day, respectively. In addition, the results showed that total organic matter was highest in rangeland (1.93 %) and lowest in orchard, pea-land and wheat-land, 1.45%, 0.95% and .97%, respectively. The highest value of total nitrogen was observed in rangeland (0.16%). Soil pH was highest in orchard (8.07) and lowest in rangeland (7.4). The results suggests that in conversion of rangeland to other land uses, garden could be less harmful in terms of soil quality.
