Concentration of N, P, K, Ca, Mg and B in the foliage ofVitis rotundifoliavaried widely between years and at different sampling dates within the year. Concentrations of N, P, and K in the foliage decreased sharply until late July each year. Calcium concentration in foliage increased as the season progressed each year while the concentration of B was similar for all dates in the same year. Variation for the concentration of Mg varied between years but no clear seasonal pattern was evident. Soil amendments of dolomitic lime or epsom salts increased the concentration of Mg in the foliage. Concentration of B in the foliage was less than normally reported for other grape species and was increased by application of B to the soil.
