There are always certain topics that get people reading, watching, and asking questions. Soil fertility is always on that list.
Whether it’s trying to better understand nitrogen loss risk, matching pounds of product to yield potential, anticipating price moves, or evaluating a new product, there’s never a shortage of interest in soil fertility topics.
Earlier this week, we tackled the phosphorus availability question on The Agronomists, as farmers know phosphorus is essential, but a pound added doesn’t mean a pound available right away. There’s also the question of whether to build soil reserves or to draw them down in a year like this.
Another key question that has come up is how to best feed modern yield potential, as genetics and management continue to push average yields higher. Then, there’s the evergreen discussion on manure or crop residue’s release of nutrients. Are we assigning nitrogen credits properly? What about other nutrients and release rates?
Seeing as we are in the crop planning season, we want to know — which fertility questions are top of mind this year?
