Evaluation of the effect of innovative organic and organo-mineral fertilizers on vineyard productivity and grape quality - The identification of organic fertilizers is a fundamental objective in sustainable viticulture. The research aimed at formulating and evaluating new fertilizers from digestate containing by-products of the wine industry in two vineyards located in Modena area. Two new experimental fertilizers, an organic (pellets from digestate) and an organo-mineral (organic fraction from digestate) fertilizer, were compared with commercial fertilizers to cv Lambrusco salamino. The results do not indicate negative effects on vegetative-productive indexes. The highest SPAD index values were recorded in plants that received the commercial mineral fertilizer, and similar values were observed using innovative organo-mineral fertilizer was applied. Total number and average weight of bunches, production per plant and must acidity did not differ among thesis. The highest soluble solids content (°Brix) of the must was observed in plants not fertilized.

Abstract

Evaluation of the effect of innovative organic and organo-mineral fertilizers on vineyard productivity and grape quality - The identification of organic fertilizers is a fundamental objective in sustainable viticulture. The research aimed at formulating and evaluating new fertilizers from digestate containing by-products of the wine industry in two vineyards located in Modena area. Two new experimental fertilizers, an organic (pellets from digestate) and an organo-mineral (organic fraction from digestate) fertilizer, were compared with commercial fertilizers to cv Lambrusco salamino. The results do not indicate negative effects on vegetative-productive indexes. The highest SPAD index values were recorded in plants that received the commercial mineral fertilizer, and similar values were observed using innovative organo-mineral fertilizer was applied. Total number and average weight of bunches, production per plant and must acidity did not differ among thesis. The highest soluble solids content (°Brix) of the must was observed in plants not fertilized.
