Soil testing is the only way to get an accurate look at what is happening in the field. Agvise agronomist Jodi Boe says soil testing takes on greater importance with the current price of fertilizer. “When we’re getting at prices of $1 per pound of nitrogen, it doesn’t really take much to get that return on investment.” Farmers may think they can use last year’s soil test data or use an average. Boe says that is a misconception. “Variability is there; just look at rainfall this past year. On your farm, you could have two inches of rain on one area and that system bypassed the next field. People think the variability in the soil is much less than what it is.”
