Hi all,

Here are my recommendations for fertilizer throughout the season.

8-3-10 - Spring Fertilizer Blend

• Nutritional
• 32-0-0 (urea ammonium nitrate)
• 0-0-25 (potassium thiosulfate) 
• 10-34-0 (ammonium phosphate)
• Evolution (22% humic acid designed specifically to work with urea --> created to reduce urea rates but increase it's efficacy --> holds onto nutrients in the soil so it doesn't leach and makes it more available to the plant)
• Reax K30 (very efficient form of potassium)
• Watermaxx II (soil surfactant --> makes sure what is being injected is uniform and permeates the soil)
• Rate: Soil 10 GAL/Acre
• $17/GAL

Reax Plus Select - Micronutrients

• Nutritional
• Contains: nitrogen, sulfur, boron, copper, iron, manganese, molybdenum, and zinc
• Apply at least twice several weeks BEFORE bloom 
  • Some apply at 3, 6, and 9-12 inches of growth
• Can tank mix with fungicides
• Rate: Foliar 1 quart/Acre
• Roughly $11/Acre

SST Calcium 

• Nutritional
• Calcium silicate --> silica & calcium are essential to cell wall & strength of cell wall
• Apply at BB size fruit set
• Can tank mix with fungicides
• Rate: Foliar 1 quart/Acre
• Roughly $12/Acre

Reax K30

• Nutritional
• Very efficient form of potassium that contains carbon to make potassium available for longer to the plant
• Apply at fruit set and throughout the rest of the season
• Rate: Soil 1 GAL/Acre
• Roughly $30/Acre

LoKomotive

• Nutritional
• Foliar potassium product
• Apply at berry sizing & bunch closure
• Can be mixed into fungicide sprays
• Rate: Foliar 1 qt/Acre
• Do NOT apply after verasion - it will mess with acids
• Roughly $8/Acre

Watermaxx II

• Soil Surfactant - really needed because our Ca:Mg ratios are inverted which means it's difficult for penetration - remember we want 6:1
• I highly recommend using this if you are injecting fertilizer (which is why it is in the blend) and/or pesticides (i.e. Wrangler)
• Rate: Soil 1 QT/Acre
• Roughly $13/Acre

Terramar (organic)

• Combination of humic acid & seaweed (Maritime)
• Really good for salt remediation
• Seaweed component is great on stress (i.e. heat, salt, cold, transplanting, etc.)
• Rate: Soil 2 QT/Acre
• Roughly $26/Acre

Maritime (organic)

• Biologically extracted seaweed
• Apply when there will be high stress 
• Rate: Foliar or Soil 2 QT/Acre
• Roughly $23/Acre

The highlighted portion is what I believe are most important to add.  Right now, the most important thing is to do the 8-3-10 fertilizer blend and the Reax Plus Select in the foliar sprays.
