Fall Fertilizer Bits to Remember

fertrigHarvest season has seemed to drag on for the most of us and with December just around the corner there is some anticipation to put fertilizer on when the crop is finally out of the field. While this might be okay in some cases, in others it is important to make sure the conditions are appropriate for applications. A recent article in The Progressive Farmer, shared their fall fertilizer tips and we have picked out the key bits to share with you.

  • Phosphorous and Potassium applications can be more flexible and it can even be better to put them on later.
  • Nitrogen should be delayed as much as possible, especially when there was fall urea applied.
  • Applications should only begin when soil temperatures drop to 50 degrees, in order to minimize nitrification.
  • Soil moisture is important to watch- too wet or too dry soil can prevent a good seal when applying anhydrous ammonia.
  • Do a short pass first and make sure you can not smell ammonia after a few minutes.
  • When fertilizing with manure, always make sure the soil is 50 degrees.
  • Frozen or snow covered soils will encourage wash off of fertilizer, so stay away from applications as much as you can in those conditions.
  • Check your wind speed.
  • Know the limitations of nitrification inhibitors.
  • Sample, sample, sample.


When purchasing fertilizer to apply, you want to make sure it is being put to good use where it needs to be. This will save you time, money, and give you healthier and happier soils for your crops to flourish. At Novus, we strongly recommend soil sampling and tracking those results through out the growing season. We do this with our Crop Camp group every year. The results from these soil and tissue samples better enable our growers to make educated decisions when applying to their soils.
