Yield and must composition of 'Cabernet Sauvignon' grapevines subjected to nitrogen application in soil with high organic matter content

ABSTRACT It is common for vineyards in regions of high altitude to have high organic matter content in soil. Furthermore, reduced miner alization of organic matter and decomposing residues is expected because of the low temperatures. Thus, soils may not provide enough mineral nitrogen (N) to meet th...
