We also have tissue samples analyzed by NutriSolutions® Tissue Analysis.

Climate FieldView™
  • Keeps all your data in one place with connectivity across many equipment types, makes, models and systems. This enables easy collection, storage and viewing of field data for more of the inputs you manage during the season.
  • Uncover valuable insights for next season with tools that help you analyze crop performance at the field level or by field zone. Use in-season imagery to identify issues early and take action to protect yield.
  • Optimize inputs to maximize yield and profitability on every acre with variable rate seeding prescription tools, nitrogen management tools and fertility scripting tools.
NutriSolutions® Tissue Analysis

Our agronomists can visit your farm at different points during the growing season to take plant tissue samples. NutriSolutions® tissue testing and analyzes pinpoint nutrient deficiencies at critical growth stages so we can help farmers make adjustments before yield potential is compromised.

We can also import tissue data results into the Climate FieldView™ and R7® Tool applications for a complete review of previous seasons to help you plan for next season.

It’s essential for farmers to have an adequate supply of liquid fertilizer during the busy spring season.

Glacial Plains offers customers the opportunity to own liquid fertilizer storage tanks. Designed as a partnership, this program increases grower efficiency while helping to minimize transportation time and costs.

  • Glacial Plains Cooperative will purchase and deliver a poly tank as large as 6,000 gallons to your farm, plumbed with a bottom bung and valve. The cost of this tank will be straight-line depreciated over a 5-year period at your expense. Glacial Plains will invoice you each year for 1/5th the cost of the tank. If you would like to buy out the tank, you may do so based on the number of years remaining on the contract. (Example: Tank cost is $3,000. Five-year straight rate is $600/year. Cost to buy out after 2 years use would be $1,800.)
  • Glacial Plains can help you determine what additional pumps, meters or plumbing you may need, but this additional equipment would be at your expense. We invoice the equipment under normal invoicing terms, or financing program.
  • Farmers participating in this program agree to purchase their liquid starter and side-dress fertilizer from Glacial Plains Coop for five planting seasons. If you don’t purchase your liquid fertilizer from Glacial Plains during this time, the contract is due and payable in full for any remaining balance.
  • Farmers are responsible for any damage to the tank until this contract expires. Growers are responsible for any crop injury caused by cross contamination issues.
  • Program participants are responsible for all equipment maintenance, including winterizing pumps, meters and plumbing.
