Objective:

To observe the comparison between a conventional dry program and a complete AgroLiquid program.

Long term averages are a great way to see how fertilizer programs affect yields. By averaging yield results over several years it takes into account different soil types that the experiments were conducted on and the different weather conditions that exist from year to year.

Each year all Agro-Culture Liquid Fertilizer programs placed phosphorus, potassium and micro nutrients in a 2×2 band with the planter. High NRG-N was used as the nitrogen source and applied as a surface broadcast after planting. Conventional programs placed phosphorus as DAP (dry spread) or 10-34-0 (2×2) and potassium as potash along with micro nutrients as a broadcast spread and tilled into the soil ahead of planting. Urea (applied the same as other dry materials) or 28% UAN (broadcast after planting) was used as the nitrogen source. All programs matched fertility needs of the test area for that particular year. The North Central Research Station uses a Gandy Orbit Air spreader to accurately spread dry materials across the entire 15’ plot width. (Note: Prior to 2007 the above planter 2×2 applications were applied 1 inch to the side of the seed and at an even depth.)

Long Term Sugarbeet Fertilizer Program ComparisonsConclusions:

  • Over 9 years, there has been an average 1 Ton/A yield advantage using Agro-Culture Liquid Fertilizers compared to a conventional fertilizer program.
  • AgroLiquid nutrients provide all of the necessary nutrition needed for a great sugarbeet crop.
