Maximizing Phosphorus Efficiency: An Introduction
Posted on December 23, 2010 |
The availability of phosphorus is vital during early growth to get corn off to a quick and healthy start since phosphorus: •Needs to be available by the V6 growth stage for maximum yield potential •Is needed for strong root development •Encourages early plant growth for longer grower seasons (drier corn at harvest) The closing grain yield is influenced by tissue phosphorus concentration prior to the V6 growth stage, regardless of the phosphorus give at later stages! Orthophosphate vs. Polyphosphate What is orthophosphate and polyphosphate? Orthophosphate fertilizers are immediately available to your corn plants. Plants can only absorb phosphorus in this form. Polyphosphate fertilizers have to break down to the orthophosphate form, and this conversion takes time. A slow conversion in cold, wet soils hampers nutrient uptake, which can negatively affect yields! NACHURS liquid fertilizers are 80-100% orthophosphate and are specifically manufactured to be placed directly on the seed
