Another Dry Year: What to Know About Leftover Nitrogen in Soil Following Dry Conditions

departure from normal precipitation 2022

With the two consecutive dry seasons in 2021 and 2022, there is likely a considerable amount of unused nitrogen left in the soil, which could be used for the 2023 crop. With the higher fertilizer prices, such fertility adjustments for next crop can be profitable as well as environment friendly. So, it is recommended to test your soil and account for all sources of nutrients for the next crop.

So What Are We Actually Measuring

When properly calibrated, soil water sensors can give irrigators an accurate measurement of how much water is currently available, and how much has been depleted, in the soil for the crop. When used along with weather data and crop water use data, this accurate measurement of soil water can help irrigators make a more informed decision on when irrigation should start, how much to apply, and when to quit irrigating. When looking at sensors, be sure to have an understanding of soil water content and how they actually measure soil water.
