Maize is a crop with high growth, with a large need for nutrients and cultured for forage to cows.

Large amounts of manure is often distributed in the fields and since maize is often grown in the same field year after year, many maize fields contains lots of phosphorus. Despite high classes of phosphorus, the recommendation is a start dose of phosphor fertilizer at growing of maize. This have shown an improved growth and higher yield (Tell mfl. 2010).

The projects innovation idea is to treat the seeds with a product, which makes the phosphorus in the soil more accessible in the start of the growth of the maize. A buffer substance, which is applied on the seeds, may affect the pH value around the seeds, which can increase the accessibility of the soil-bonded phosphorus. Another way could be to apply a smaller amount of phosphorus directly on the seeds. Since the phosphorus is applied directly on the seeds, the possibility increases that the plant takes up all of the distributed phosphorus and the utilization gets efficient. The amount of phosphorus in the seed treatment is significant lower than with combi-drilling.

To reduce the distribution of phosphorus, reduces the environmental strain and improves the framers economy.
