Compost Application to Degraded Vineyard Soils: Effect on Soil Chemistry, Fertility, and Vine Performance

Abstract

A two-year experiment investigated the effects of compost application rate on soil chemical properties, vine nutrient status, vine performance, and grape juice characteristics in a degraded vineyard soil in northern California. The intent of the research was to identify vineyard management strategies to improve soil fertility and to identify optimal compost application rates. We applied composted steer manure at three rates (11.2, 22.4, 33.6 t/ha) in a randomized complete block design before the 2012 growing season. Pruning and berry weight increased over the control at the highest application rate in both years, while vine yield significantly increased over the control in year two. Polynomial orthogonal contrasts suggest that pruning weight, vine yield and berry weight increased linearly with increasing compost application rate in 2012, and that vine yield and berry weight increased linearly and quadratically with compost application rate in 2013. Measured soil properties increased from compost application, including N, C, pH, exchangeable K, Mg and Ca and available P (Olsen-P), while phosphorus fixation

Fertilization with different soil types in viticulture: a three-year experience in Trentino Alto Adige

“…Observing the musts quality parameters, the occurrence of a delay in maturation for the plants treated with soil improvers could be assumed. This is in agreement with the vegetative data results, and in according to recent work with compost [8].…”

Composting from organic municipal solid waste: a sustainable tool for the environment and to improve grape quality

“…The treatments were applied in autumn 2017 and autumn 2018 with a manure spreader machine. Compost was applied on a per hectare basis, with a single application in bands that were lightly incorporated (10–20 cm) into the soil directly under the interrow (Wilson et al ., 2021).…”

“…Four soil treatments were applied (three compost The treatments were applied in autumn 2017 and autumn 2018 with a manure spreader machine. Compost was applied on a per hectare basis, with a single application in bands that were lightly incorporated (10-20 cm) into the soil directly under the interrow (Wilson et al, 2021). At the composting Center of Faltona (Alia Servizi Ambientali SpA, Borgo San Lorenzo, Italy), with the technical and scientific supervision of the Agricultural School (DAGRI, University of Florence, Italy), in a specially set up area tests were carried out to obtain quality compost, derived from organic waste matrices selected from separate collection from MSW, agri-food waste, etc.…”

Deep incorporation of organic amendments into soils of a ‘Calardis Musqué’ vineyard: effects on greenhouse gas emissions, vine vigor, and grape quality

“…So far, results of different studies are contradictory. While beneficial effects of OA incorporation on parameters such as vegetative growth or yield could be shown in some studies (Genesio et al, 2015;Gaiotti et al, 2017;Tangolar et al, 2020;Marıń-Martıńez et al, 2021;Wilson et al, 2021), others reported no or only negligible influence on grapevine performance (Mugnai et al, 2012;Schmidt et al, 2014;Baldi et al, 2022). Some studies reported even negative effects on grape quality parameters (e.g., Gaiotti et al, 2017;Botelho et al, 2021).…”
