Cover crops and pruning in Bobal and Tempranillo vineyards have little influence on grapevine nutrition

Abstract

Cover crops may improve vineyard soil properties, grapevine nutrient status and berry composition, however, factors such as cover crop type, annual rainfall, climate and irrigation may change their effects on vineyards. From 2008 to 2011, the effects of a non-permanent cover crop and two pruning techniques on soil as well as vine nutrients and grapevine performance of two vineyards (cv. Tempranillo and cv. Bobal) were evaluated. For that purpose, two legumes were sown in inter-rows of hand-pruned vines in February and were tilled at flowering.Soil tillage, or cover cropping, was combined with either light pruning or severe pruning to study foliar nutrient variations. Soil N, P, K and total organic carbon (TOC) were determined in samples taken from the Ap1 horizon in January prior to vine pruning. Foliar N, P, K contents

Effects of alternative cropping systems on globe artichoke qualitative traits

“…The introduction of leguminous crops (catch-and cover crop) in globe artichoke cropping system and fresh residues incorporation management, maintained soil N as in CONV (with N mineral fertilisation), due to the ability of legumes to symbiotically fix atmospheric N 2 and by the amount of mineralisable N supplied by fresh residues incorporation into the soil. 30 Our results for soil P, agree with those reported by Pérez-Bermúdez et al 31 which stated that availability of soil P remained virtually unchanged in both treatments with cover cropping with respect to a bare soil one. Alternative managements with catch-and cover crops had little influence on K and Mg soil availability.…”

Cane Pruning Intensity of Vine as a Substantial Factor Influencing Physico-Chemical Attributes of Berries Cultivar ‘Regent’

“…It should be emhpasised that the treatment had statistically significant meaning for the concentration of all macronutrients in berries. In contradiction, as reported by Pérez-Bermúdez et al (2016), light pruning, next to cover crops, did not alter the foliar N, P, K concentrations of 'Bobal' and 'Tempranillo' cultivars, which were similar to those found in leaves from vines with soil tillage or severe pruning. In our experiment, higher intensity of pruning led to a greater accumulation of most tested macroelements.…”

Soybean Yields and Biomass Production of Winter Cover Crops in the Southwest of Parana – Brazil

“…Their use is widespread since the introduction and consolidation of no-tillage systems (NTS). In addition to protecting the surface of the soil, these plants improve the physical, chemical and biological properties of the soil (Derpsch et al, 1985;Giacomini et al, 2000;Pérez-Bermúdez et al, 2016;Rosseto et al, 2017).…”
