The world continues to change when it comes to the application of nitrogen to corn crops. The increase of extreme weather, ever-changing nitrogen uptake by corn hybrids and farmer’s efforts to find out how much available nitrogen exists are pushing the growing interest in more advanced nitrogen monitoring tools.
Yield analysis experts say a number of systems exist, but they are often too similar. User inputs of field data like cultural differences, types of soil, management practices and so on complicate the problem. The systems that rely on historical weather data and agronomic nitrogen cycles estimate the amount of available nitrogen could be useful in different scenarios.
Two factors are driving the implementation of products that model nitrogen. One is increasing extreme weather events and heavy rain. The second is changes in the level of nitrogen uptake in corn hybrids. New hybrids take nitrogen at a later point in the season than older ones.
Farmers have embraced new digital tools and technology, and many have enjoyed an average increase in their profits. The level of yield improvement is highly variable, largely based on the weather, specific field characteristics, and individual management practices.
Despite the growing popularity of modern nitrogen modeling devices, some industry experts still insist that more traditional methods of testing for nitrogen in the soil and in plant tissues are superior and more accurate than the modern digital modeling systems.
