Fertilizing

A January 2022 webinar from Utah State University Extension addressed the results of alfalfa nitrogen credit studies looking at whether corn or small grains responded to nitrogen applications in the first two years after alfalfa termination.

Fertilizers play a very significant role in agricultural production, with 30% to 50% of the world crop yields being attributed to fertilizer use. Nitrogen (N), phosphorus (P) and potassium (K) are the primary fertilizers used in the agriculture sector.

With the price/supply squeeze coming tighter during spring fertilizer purchases, farmers are looking for options that will still support high yields. It has been clear from looking at soil samples over the past 40 years that fields with regular manure applications are testing high to very high in phosphorus (P).

Modern dairy production relies on capturing nutrient and production efficiencies for the animal and cropping sides of the business to optimize profitability.

Fertilizer bills can be some of the largest bills on the farm. Applying the precise amounts at the right time and in the right way can drastically influence farm profits.

Now that the calendar has flipped to 2021, it’s important to evaluate how your weed management program performed in 2020 so you can make informed choices about this year’s inputs.
