Abstract :

In the present study, the contour furrow operation germinated with seeding was evaluated in Bolbol pasture with 108 mm of annual rainfall and 4.47% vegetation cover. For this purpose, two control sites and contour furrow sites were identified and the characteristics of vegetation and soil within each site were investigated. Vegetation characteristics include: total canopy cover, density, Artemisia canopy cover, uniformity indices, richness and diversity of species and soil parameters include: Soil permeability, soil moisture and carbon stabilization. According to the results of analysis of variance, the effect of contour furrow on the Artemisia canopy cover, the percentage of total canopy cover, uniformity and richness of species and soil moisture in May was significant at 1% and the effect of furrows on species richness at 5% was significant. Implementation of furrow operations with an average 550 m lenth per hectare has increased the vegetation canopy cover by 1.32% and the Artemisia canopy cover by 1.08%. Increase in vegetation canopy cover on the furrow site Due to the moisture stored in the furrow, which is 20% higher than the control site in May, more suitable conditions are created for vegetation inside the furrow. The maximum ecological potential of the study area and regions with similar climatic and adaptive conditions is 1.32% increasing canopy cover of vegetation, which should be considered in the executive plans.
