What do we know about heavy metals in soil? What do we know about lead exposure through soil and garden plants? What do we know about cadmium and arsenic in soils? What can I do if I’m at risk for heavy metals in my garden soil?
This article describes how to determine vineyard nutrient needs through grapevine tissue and soil sampling. It also provides tissue testing guidelines.
Mobile drip irrigation efficiently delivers water to crops where it's needed and minimizes the amount of runoff. It delivers 10%–25% more water to the soil per gallon of water than traditional sprinkler systems.
Farmers can improve irrigation efficiency by scheduling irrigation, adopting deficit irrigation and conservation tillage practices, and installing more efficient irrigation systems. Sprinkler and drip irrigation systems are more efficient than furrow irrigation. S
For blueberry growers, water management is a key to success. The goal is to apply the correct amount of water at the right time to minimize irrigation costs and maximize crop production and economic return.
Pacific Northwest blueberry growers must identify and control a number of bacterial and fungal diseases in order to ensure the highest yields. Fortunately, only a few of the diseases that occur on highbush blueberry in this region cause significant losses when left unchecked.
