This article describes how to determine vineyard nutrient needs through grapevine tissue and soil sampling. It also provides tissue testing guidelines.
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.
Silage-making has been used to reduce the concentrations of toxins in a variety of crops. But in the case of poison hemlock, the opposite is true — making silage out of it actually increases one of its toxic alkaloids.
Some plants absorb excess nitrates or oxalates from the soil and store them in plant tissues. Toxicity problems can occur in animals which feed on these plants.
