In an article in Corn E Digest  OSU Extension Economist Barry Ward says that corn and soybean production costs are expected to increase 24-35%. He follows up with some steps to cut costs.

Mr. Ward why not suggest that farmers make what fertilizer is already in the soil available by liming?

We've discussed this before, here.

At a 5.5 pH, 25% on Nitrogen and Potassium is not available to crops. Over 50% of phosphorus is not plant available.

Seed selection is important, but pH is more important. At a 5.7 pH you lose 17% of your corn’s genetic potential, before it’s planted and it doesn’t matter what hybrid.

Lime price have remained relatively stable compared to other fertilizer products.

Does it really make sense to continue to dump high priced acid and salty fertilizer on you ground when it cost $400-500 per ton? So you bought it a little cheaper in the fall, if 25-50% is not available to your crop, that’s like paying more up front for less.

We know that proper soil sampling, keeping pH above 6.5 (for corn), having proper levels of micro and secondary nutrients (not adequate) will produce higher yields for less than blasting the soil with P and K, even when it was cheap!
