    Proposal summary:

    We are concerned that poor soil health is impacting the health of our vines and subsequently the quality of our grapes. We recently had to remove an acre of 30-year-old vines because they were failing to produce quality grapes. We want to determine if improving soil health through worm casting inoculated wood chips and enhancing beneficial insect habitats will improve the nutrient density and flavor profile of our estate grown wines.

    After placing the worm tea inoculated chips around the vines, we will be foliating the vines 3x a year for 3 years; we will be testing the soils at the beginning of the grant, as well as 2x year for 3 years to see if we can achieve a balance of biologicals and fungi.

    With the increasing impacts of extreme weather and less available irrigation waters, the need for sustainable farming practices increases daily. As a small family farm, our labor is by hand. We hope Inoculated wood chips will retard weeds and preserve moisture in the soil. We hope good soil health will enable greater water retention, enhance vine resistance to disease and increase nutrient values of fruit.

    We will share our practices and findings by hosting an onsite workshop in the vineyard available virtually, sharing our results on our website and www.adaswcd.org and print media.

    Project objectives from proposal:

    1. Build soil health, to expand the soils water holding capacity and create habitat for beneficial insects and pollinators through regenerate agricultural practices. 2. Increase Macronutrient density of grapes as a result of improved soil health 3. We will share project results with surrounding vineyard owners/managers by hosting 2 onsite workshops, blog posting to www.bitnervineyard.com and https://adaswcd.org/ and presenting project results at the Idaho Wine Commission’s annual meeting.
