MAXIMIZING PHOSPHORUS EFFICIENCY
PHOSPHORUS IS CRITICAL FOR EARLY GROWTH
The availability of phosphorus is critical during early growth to get corn off to a quick and healthy start because phosphorus:
The final grain yield is influenced by tissue phosphorus concentration prior to the V6 growth stage, regardless of the phosphorus supply at later stages!
ON THE SEED
- Most efficient placement
- Phosphrous placed for maximum plant efficiency
- Roots are in immediate contact with fertilizer
2" x 2"
- inefficient placement
- Roots are not in immediate contact with fertilizer
- Not efficient
Dr. Wilcox of Purdue University reported that 5 Ibs/A of phosphorus banded with the seed was equivalent to 20 Ibs/A of phosphorus two inches under the seed.

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!
