Row spacing for both corn and soybean is an important decision to make for any crop producer and can lead to high yielding crops. Corn row spacing is important to maximize yield as well as to keep balanced with economic output.

Corn row widths continue to decrease as time moves forward....

Planting soybean in the same field that just grew soybean is not recommended. Soybean yield will suffer even before factoring in environmental conditions, weather, and pest/disease pressures. 

Four different studies in Minnesota and Wisconsin have shown a yield decline of at least 5% and...

Across Iowa, the forecasted average day/night temperatures are between 30 to 40 degrees F in the coming ten days, so the time is right to cool any grain that went into the bin at higher temperatures. Good harvest conditions and warm weather early this fall mean that there is on-farm grain that...

With rising fertilizer prices, and concerns about possible shortages, it pays to time our applications of anhydrous ammonia and manure well. When the value is high, the focus on management is even more important.

Anhydrous costs are reported to have risen to $850 or more per ton.
