A foliar feeding of slow release nitrogen during the growing season has been proven to give plants an instant boost at a critical growth stage while also sticking with your crop long-term, continuing to provide critical nutrients to plants as they mature toward harvest.

When used in combination with SOIL Service’s Foliar Opp, you have the potential to add 10 to 15 bushels of top-end yield in corn or 5 to 12 bushels for beans. Because both products are effective in corn and soybeans depending on the situation, our experts will recommend the combination that is right for your crop and the current growing season.

SOIL Service offers two specialized slow release nitrogen products that we’ve developed and tested.

Max72-SRN®

Containing the maximum percentage of slow release nitrogen available on the market—72 percent—our Max72-SRN product is a non-burning solution for use on row crops, turf, vegetables, and fruit. At a rate of one gallon per acre, it offers more than three times the slow release nitrogen of many competing products. Tests have shown Max72-SRN remains available to crops for up to six weeks in the soil and three to four weeks on the leaves.Jug-Max-72-SRN-web

Foliar feeding Max72-SRN minimizes N loss and coats leaves, lasting for weeks while the plant tissue absorbs it. Its staying power makes it an ideal delivery partner for both crop protection chemicals and glyphosate herbicides, keeping these products on the crop or the weed for a longer period of time.

How to put Max72-SRN to work for your crops

  • Add to a fungicide at the tassel stage of corn to have a positive impact on yield
  • Apply to R3 soybeans with insecticide and fungicide
  • Apply to wheat with herbicide and fungicide—a great way to add supplemental N when wheat needs it
  • Tank mix with a glyphosate or another post-herbicide application
  • Tank mix with NPK fertilizers or micronutrients
  • Incorporate with drip irrigation or sprinkler irrigation

2075-SRN®

When crops need a nutrient boost during the growing season—especially if they have been put under stress from heavy rains, wind, or hail—2075-SRN is SOIL Service, Inc.’s, solution. A clear liquid fertilizer using our high-performing Max72-SRN as a foundation, 2075-SRN delivers nitrogen, sulfur, and potassium for crops to absorb virtually any time during the growing season. It can be applied as a foliar spray or via an irrigation system and mixes well with herbicides and fungicides.
