Abstract

Soil organic matter (SOM) is considered a fundamental element for the vitality of agricultural soils. The depletion of SOM is a main concern for grape-growing compartment as the increase of mechanical approach is fastening its degradation. SOM loss in vineyard soils lead to a decrease of yield and quality of products as a consequence of a reduction of soil chemical and biological fertility. In order to contrast SOM erosion, research aiming at finding sustainable management practices are enhancing in agricultural sector. In the present study a three-year research was carried out in vineyard with the aim to compare the application of three different organic fertilizers. The effects of organic fertilisation on vines, grapes and wines were investigated in five different Italian wine-growing areas. The positive effect of organic fertilisation is highlighted, especially in the conservation of acidic content of the must. The effect of fertilization is also revealed in differences in wine aromas at wine tasting.

Highlights

In 2009 the European Union defined soil organic matter (SOM) as the very foundation for healthy soils, highlighting how its erosion causes the degradation of the soil itself
Data obtained in 2017 and 2019 are reported with the aim to compare the first and the last year of distribution, as the mineralization of organic matter is a slow process over time and more years should be necessary to see fertilizers effects on plants [15]
This study reports some interesting element to better understand the effect that SOM apported with different organic fertilizers can determine on the vines, musts and wines

Summary

Introduction

In 2009 the European Union defined soil organic matter (SOM) as the very foundation for healthy soils, highlighting how its erosion causes the degradation of the soil itself. The importance of SOM content has long been known [1, 2], but it has been further highlighted by the progress in the knowledge about soil composition [3, 4; 5; 6, 7]. SOM positive functions lie both in a general improvement of fertility conditions, and in positive effects in soil structure, water retention and nutrients availability. SOM is: - a “source of food” for subterranean fauna and contributes substantially to soil biodiversity; - the core of soil fertility: organic carbon strengthens soil structure and promotes the penetration of roots into the soil improving the physical environment; - capable of holding up to six times its weight in water. Soils containing more SOM have a better structure, which helps the infiltration of water and reduces soil susceptibility to compaction, erosion and landslides [11]
