Even if you already have a farm manager, a PCA, and a full staff, Precision Ag can add specialized services in a particular area and be an asset to your team. We will work closely with everyone in your farming operation to bring every aspect of grape production together.

Vineyard Production Consulting

While we believe that the best way to produce premium quality wine grapes is to have your vineyard professionally managed, we also realize that this one-size-fits-all approach does not work for every grower and every vineyard size. This is why we also offer individualized vineyard production consulting services. These services are specially designed to suit your needs and are billed on an hourly or project basis.

Water Quality Appraisals

We conduct water sampling services to evaluate the suitability of irrigation water for all types of agricultural production. We will collect the samples, have them analyzed by a professional lab, provide you with a detailed interpretation of the analysis, and help you with recommendations on what to do with the information. Water quality analysis includes tests for salinity, toxicity, nutrient, and nitrate-nitrogen levels.

Soils & Fertility Management

Soil analysis in vineyards can provide information on pH and salinity issues. Precision Ag can provide analysis and recommendations regarding these issues.

We can help you determine fertilizer requirements through the use of plant tissue sampling for nitrogen, potassium, phosphorus, zinc, boron and other nutrients. We also provide petiole sampling services and can develop a nutrient budget and fertilizer recommendations for your vineyard.

Soil Suitability Investigations

Whether you have an existing vineyard or are planning a new one, we can assist you. We develop soil surveys for texture, drainage, rooting depth, uniformity, salinity levels, and pH. These tests help manage different areas individually, and this leads to greater uniformity.
