Because of the dry conditions last year, there is higher residual nitrogen in the soil. Jason Hanson, who leads Rock and Roll Agronomy, expects to see adjustments made to a normal crop rotation. “I don’t want to see soybeans put on wheat ground because that would be the normal rotation when I have 90 units of nitrogen out there,” said Hanson. “I’m better off putting canola or corn on that field or even putting wheat back.” While soil testing takes on more importance this year, Hanson is surprised by the number of farmers who don’t take that step. Farmers are also questioning the data this year. “They don’t believe a high number, but they believe a low number.”
