Wheat School: Doing the math on 2021 straw value

[ad_1]

Ought to growers promote their wheat straw after 2021 harvest?

That’s a query RealAgriculture agronomist Peter Johnson has been requested usually in latest weeks. With fertilizer costs up 125 per cent and straw costs hovering round three cents per pound, many growers say they might slightly blow the straw again on the subject, take the nutrient credit score and return the natural matter slightly than promote at that value.

However earlier than making their last determination, Johnson is asking growers to observe his thought course of and contemplate promoting. On this episode of RealAgriculture’s Wheat College, “Wheat Pete” notes that the complete value of macronutrients —phosphorus, potash, magnesium, sulphur and nitrogen — in addition to the micronutrients, is just about one cent per pound.

Johnson concedes that straw does return priceless natural matter again to the soil; nevertheless, he factors out that residing roots are even higher for soil well being. That’s why he would slightly promote the straw and use a part of the proceeds to finance planting a canopy crop that may create much more roots in the soil.

Johnson notes that returning straw to the subject also can create residue issues when it’s not unfold evenly. He thinks three cents is sufficient to justify the sale. “If it gets the residue out of the way and it will make you plant a cover crop — sell the stinking straw!”
