Micronutrient mobility in soil under different management practice in organic vineyards

Abstract

The current study aimed to improve micronutrient mobility in soil using different soil management practices in organic vineyards,
where a holistic approach to agricultural production sets a number of limits compared to conventional farming. Therefore, we applied several already well-known practices to monitor changes in micronutrient composition and their potential availability to plant, while assessing them as possible pollutants of the environment if an access amount is mobilised. The study was conducted in three different soil-climatic conditions under established organically managed vineyards, were micronutrients such as Mn, Fe, Cu, Mo, Ni, Zn were observed. The results have shown that cover cropping with grass mixture, mulching with wood chips, and application of organic fertilizer had a positive impact on the increase of mobility and bioavailability of Mn, Fe, and Mo. Although, in some cases reduction in nutrient mobility was observed, especially in the case of Fe and Zn.
