Nutrient Management Research Database

A growing viticulture industry in New Mexico has sparked a need to establish best management practices for the climate and soil conditions present across the state. A survey of soil and water characteristics in established New Mexico vineyards was performed so that appropriate management strategies could be developed and limitations could be identified. Soil nitrogen levels varied from low to high indicating potential problems for management. Plant tissue testing needs to be included in a phosphorus nutrition program because of the potential effects that myccorhizae fungi can have on plant phosphorus nutrition. Research and extension programs that address water and nutrition management may have the greatest impact on New Mexico's Vineyards.

• Soil samples were taken at 14 vineyards across New Mexico from July 6th to July 10th, 2004.
• Vineyard data on type of grape grown, irrigation system, and vine spacing were taken.
• The soil samples were analyzed for nutrients levels, texture, boron, salinity, chloride, calcium carbonate, and gypsum.
• The second foot of soil was analyzed specifically for:
  • texture
  • nitrate-N
  • phosphorus
  • potassium.
• Irrigation water was also tested for nutrient levels.

• Soil nutrient levels varied across the vineyard sites.
• Understanding the water and soil nutrition status is necessary for vineyard management.
