Soil health involves chemical, biological and physical aspects. For now, let’s examine how physical aspects can be degraded over time and how you can improve them.
Since yield potential is determined in the first six weeks of growth, phosphorus (P) needs to be available early, especially with cold soil, continuous corn and P-fixation issues.
Nitrogen, phosphorus and potassium get all of the publicity, but if there was an Academy Award for crop nutrients, sulfur would win best supporting actor.
Applying nitrogen—corn’s most important and trickiest nutrient—doesn’t do a lick of good if it escapes into the air or, even worse, into water sources before plants can use it.
