“Bound. Fixed. Unavailable. Three words no grower wants to hear about one of the three most important nutrients in crop production. However, this adequately describes the nutrient known as phosphorus (P).“
So writes CHS Agronomy agronomist Codee Lee in a recent article published by CropLife. He says that while total soil P concentration is very high, it’s estimated that crops will seldom get more than 15%-20% of the P applied in fertilizer.
Knowing this, what advice can retailers give to growers to better effectively manage this critical nutrient? Phosphorus management and efficiency comes down to understanding the nutrient, each crop’s need, the soil properties, and making informed decisions on the type and rate of fertilizer used.
Codee takes a closer look in this in-depth article on phosphorus – providing several tips to growers on how to make P more available to plants.
