This article describes how to determine vineyard nutrient needs through tissue and soil sampling.
This collection of links and publications are compiled information about managing nutrient levels in your pasture. This includes soil testing and assessment, application of fertilizers and minerals, and nutrient cycling in a forage pasture.
Information on vineyard water management, focusing on when to initiate irrigation.
Excessive summer irrigation of oak and madrone trees may promote fungal diseases such as the oak root fungus (aka armillaria root disease) and crown rot.
This is a guide that can be used by wine grape growers to interpret their vine tissue nutrient analysis results to determine nutrient sufficiency, deficiency or excess.
