The Importance of Fertilization in Wheat – Starters and Nitrogen
In this guide, you will be able to review several trials in wheat over several years. You will see a higher level of profitability with a Premium liquid starter, and also at what rate it is no longer profitable to add nitrogen.
The purpose of a liquid starter like the 7-24-3 (5*) is to stimulate plant growth early on to help the roots establish quickly. The keys to the starter’s efficiency are its high phosphorus availability and its speed of absorption. An optimal N:P ratio is also an important point factor to consider when choosing a starter.
Nitrogen fertilization in wheat
Through dozens of tests carried out over three years, we have compared the financial profitability of several doses of nitrogen in wheat. You can clearly see in the graphs below that the higher the nitrogen dose, the higher the yields. The challenge is to determine at which nitrogen dose it is no longer profitable to add more.
