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.
