Title

Estimation of Soil Loss Due to Potato Harvesting in Ghorveh-Dehgolan Plain, Kurdestan Province

Pages

  177-186

Abstract

Soil erosion is an important environmental hazard with on-site and off-site effects that gradually cause soil quality deterioration, land degradation, surface water contamination, and reduction of dam’ s reservoirs capacity and finally threats the human Food security. The soil loss due to the crop harvesting (SLCH) is a form of soil transportation processes which has attracted a little attention in comparison with the other types of Soil erosion. Therefore, the objective of this study was to determine the soil loss by potato harvesting process in the Ghorveh-Dehgolan plain, Kurdestan province. For this purpose, twenty samples, each containing 5 kilograms of potato, were collected from Rainfed and irrigated farmlands of the study area. The samples were washed out in the laboratory to separate the soil from potatoes and then the suspension was filtered and dried to determine the SLCH. The results indicated that the amount of SLCH ranged from 13. 4 to 40. 4 g kg-1 of potato. The one-way ANOVA test indicated that there was a significant difference between SLCH of Rainfed and irrigated farmlands (p<0. 05). Cluster analysis was also demonstrated that there was a weak correlation between SLCH and land use in the study area. The estimated SLCH from 80490. 4 ha of potato farmlands during the past 10 years was 72374. 53 Mg which is equal to 7237 Mg year-1. The average SLCH ranged from 0. 66 to 1. 14 Mg ha-1 during the harvesting processes. The results of this study confirmed that the SLCH has the same importance as the other types of Soil erosion and should be considered in soil conservation activities.
