First three sentences: Tissue analysis in vineyard nutrition is much more effective and reliable than soil analysis. Soil analysis does not give an accurate indication of the nutrient status of the vine. The many types of vineyard soils, the vines' potentially deep and far-ranging root system, differing irrigation practices, and the inherent differences in nutrient uptake by grape varieties and rootstocks are largely responsible for the inability to correlate soil nutrient levels and vine nutrient status.
