Looking at the value of timely water intervals and the role they play in micronutrient uptake in corn. We all know that watering corn at specific growth stages can make a crops yield potential change dramatically. Something that is commonly overlooked is, while having the available moisture for nitrogen uptake, the need of water availability for key micronutrients uptake to help with finishing grain development. First what we need to look at is making sure the soil series is compatible with producing corn. Then we can move on to seeing what nutrients a soil sample tells us we need to generate a high yielding crop on that particular fields soil. While knowing nitrogen plays a great role in corn production there is a large interest in what micronutrients we are falling short on being available. Once we know what the soil sample tells us we can start to determine what the right approach is to applying both macro and micronutrients for plant uptake. The way we determine how to continually keep the needed nutrients available is by taking tissue samples and adjusting what we apply with more timely fertilizer applications. While making sure we make timely fertilizer applications we need to also be sure we are making timely water applications to help with the intake of these closely determined nutrients applied. The way we look at this is determined is by the use of soil moisture sensors and keeping the correct needed levels of moisture content in the soil. Something to also keep in mind is paying attention to other yield limiting factors such as the commonly known corn disease, Southern Rust, and the most known corn pest, southwestern corn borer. Integrated pest management always plays a key role in maximizing corns yield potential. While trying to key in on macro and micronutrient uptake, being able to keep other outlying yield factors controlled helps with making sure your nutrient research is maximized.
