INFLUENCE OF VEGETATION COVER ON THE QUALITY OF SOIL LOSS

Soil erosion by water is a pervasive and a significant environmental problem affecting all sloping terrains, causing soil physio-chemical changes and soil displacement. Considerable modification of the soil chemistry leads to decrease in soil fertility and in a disrupted nutrient balance. In this context, soil pH and organic matter content are of great importance as fundamental factors of soil fertility. Therefore, the basic objective of this work is to determine the influence of inter-row use on the soil quality affected by water erosion in the vineyards. The research included different treatments in two vineyards ; grassed inter-rows and bare inter-rows. The vineyards are located in the same position, slope and soil type. Grassed inter-rows in the vineyard belongs to the family farm Mladen Papak, while the treated bare soil in the rows belongs to the vineyard of the family farm Drago Papak. The results of laboratory analysis show the influence of different soil use in vineyards on the changes of soil pH and soil organic matter content. Based on them, it is recommended to grass the inter-row space due to reduced soil erosion by water, retention of plant mass and organic matter, non-compaction of the inter-row space and easier passage of machinery through the rows. Also, it is important to emphasize and determine the direction of planting rows in vineyards because the direction of the row itself negatively can affect the increase of soil erosion by water. The results of this research indicate the importance of applying all preventive measures in reducing soil erosion by water on sloping terrains.
