Prices for DAP, urea, anhydrous ammonia and UAN have all reached all time high prices.The cost per pound of actual N is over $1.13/pound for urea and 32% UAN. Last year we were complaining about the increasing cost of fertilizer, and it was only about half the cost it is now.

What should you do if you cannot afford fertilizer?

You have 2 choices, 1) apply fertilizer at a targeted rate or 2) don’t apply any fertilizer.

In either case, you will need to improve management.

If a producer does not normally fertilize pastures and/or hay fields, then there is little consequence of not fertilizing since his stocking rate should already be matched to the natural productivity of the land. However, if the producer has been fertilizing pastures to support his livestock operation, then cutting back fertilizer will require improved management to increase the utilization of the forage and to allow enough rest between grazing cycles for the grass to remain healthy. Also the fertilizer that is applied must be targeted to specific times of the year at rates that match livestock need to prevent excess forage growth and waste of fertilizer value.

For each ton of hay removed from a field about 30 to 40 pounds of nitrogen, 14 pounds of phosphorus, and 45 to 50 pounds of potassium are being removed.When cattle graze or are fed hay most of the nitrogen, phosphorus, and potassium are returned to the pasture in excreta. So, improved grazing distribution of grazing and hay feeding will improve the distribution of recycled nutrients.

Weed control increases forage production. For each pound of broadleaf weed production, we see grass production decrease by at least a pound. Controlling weeds is therefore even more important in drought and high fertilizer situations.

In summary, with high fertilizer prices we need to improve forage management, cull the cowherd to reduce stocking rates, practice weed control, and consider seeding legumes in the fall to help out next spring.
