Organic carbon dynamics in interrows of Vitis vinifera with different years of soil use and management

Abstract

This study aimed to evaluate the effects of soil use and management on organic carbon stocks in the interrows of Vitis vinifera with different years of cultivation. A vineyard located in Rio Grande do Sul state, with 4, 9 and 16 years of management, was evaluated. Soil samples from different layers, 0.0-0.10, 0.10-0.20, 0.20-0.30, 0.30-0.40, 0.40-0.50 and 0.50-0.60 m, were collected on wheel tracks, between wheel tracks and under the planting rows. As a reference, samples were collected in native grassland of the region. Organic matter content, bulk density and soil porosity were evaluated. Carbon stock was determined according to the correction of the sampled thickness. The results were subjected to analysis of variance and means were compared by Tukey test at 0.05 probability level. Soil management caused alterations in its structure and organic matter content, observed mainly in the first 30 cm, regardless of the area studied. Highest values of bulk density were observed on the tractor wheel tracks, followed by under the planting row and between wheel tracks. Alteration in soil cover for vineyard planting led to a reduction in the carbon stock, compared to the native grassland. The area under management for 4 years showed higher carbon stocks between the wheel tracks, whereas the areas under 9 and 16 years of management showed highest values in the wheel tracks.

Stand age and soil organic matter management as driven factors of soil biota community composition and soil chemical properties in a subtropical Acrisol

“…Several studies have investigated the effects of organic residue management on Vitis vinifera L., Malus domestica (Borkh), and Prunus persica (L.) Batsch (Frene et al., 2020; Santos et al., 2021), focusing on soil biota abundance in various soils and countries. These studies have observed a decrease in the diversity of soil organisms associated with reduced input of organic residues.…”

Physical-Hydraulic Quality Indicators of soils with different years of management under Pinot Noir (Vitis vinifera L.)

“…Mechanization, along with other agricultural practices, has contributed to a significant increase in crop yield and reduction in production costs over the last century. However, indiscriminate use may lead to increased density due to alterations in pore shape, which reduces permeability to water, and these indicators are the most studied to evaluate the effects of soil use and management in agricultural areas (Santos et al 2021).…”

Changes by use and management in alluvial plain soils in southern Brazil

“…al (2021) in a study of changes in soil and clay fraction after cultivation with viticulture showed that there is change in chemical attributes, mineralogy and soil fertility over the years, especially where the soil is managed for a longer time with the input of chemical fertilizers. Santos et al (2021), they concluded that soil management caused changes in soil structure and organic matter content, especially in the first 30 cm, when subjected to tractor weight in the planting line. And changing the ground cover for planting vines leads to a reduction in carbon stock, compared to native pastures, for example.…”
