Jillian Cline with Nutrien Ag presented at our April meeting. Below is the spring fertilization recommendation she put together, with pricing.

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.
