This article describes how to determine vineyard nutrient needs through grapevine tissue and soil sampling. It also provides tissue testing guidelines.
Potassium is an essential nutrient in corn production. If deficient, growth is stunted and yields are reduced. Potassium deficiency will manifest differently as the season progresses. Here's what to look for.
Nitrogen, phosphorus and potassium aren't just an alphabet soup of chemicals. They are essential plant nutrients that, when used correctly, help to grow a healthy garden. Learn what fertilizers to apply when in this handy guide.
Collection of forage resources, mostly for Coastal Oregon regions. Includes studies on fiber digestibility, phosphoric soil, rations, and cost/benefit of growing and buying locally grown forages.
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.
