Illinois farmers are always trying to do better.
Whether with their land, their animals, the chemicals and fertilizers they use, or the feed they provide, farmers are always looking to take care of their resources in a way that preserves them for future generations.
This is why updated scientific information about how much phosphorus and potassium corn and soybeans are using from the soil is SO important to farmers.
Every year, farmers soil test to determine what their soils are lacking and then they add those nutrients to provide for the next year’s crop. When calculating how much of which nutrients to add, farmers have to take into account what crop just grew on that plot of land and what crop the farmer plans to plant there the following year.
New scientific information is telling farmers this year that a field of corn only uses .37 pounds of phosphorus per bushel of corn produced and .24 pounds of potassium per bushel. These numbers will figure into the calculations of what the farmer should add back to the soil to replace what the crop used.
These new numbers are 15 percent less than the previous scientific guidance.
To summarize, based on better seed genetics and better management practices, our crops are requiring less phosphorus and less potassium to thrive than before! And that means that farmers can apply less of these fertilizers when planning for the next year!
Good, sustainable news all around.
