Most fields are showing symptoms of wind damage and sand blasting, too, in some cases.
Most fields are showing symptoms of wind damage and sand blasting, too, in some cases. Now is a good time to look for signs of low pH, such as poor stands, phosphorus deficiency (purpling), or stunted roots and yellowing. If you are concerned about low pH, a 0-3” and a 3-6” sample for impacted zones would be beneficial. If pH in these zones is below 5.5 for either depth, nutrient tie-up is likely, aluminum toxicity is impacting root growth and water uptake, some herbicide breakdown may be impacted, and an application of lime is recommended. Low pH is going to be different than salinity (white spots in field), but it is possible to have both issues in the same field.
