The hot and dry weather that’s shifting into the Midwest likely will stress plants that have a shallow root system after being planted so late.
A lot of the Midwest stretching from Nebraska into southern Michigan will see lower than 50% of regular rain within the subsequent ten days, in keeping with a report from Commodity Weather Group.
Temperatures are anticipated to prime 100˚F. This week in southern Nebraska, Kansas, northern Missouri, and southern Iowa, the forecaster stated. Crop stress is expected in about half of the south-western Midwest with the main yield risk to early pollinating corn.
The weather hasn’t been overly hot thus far, however with temperatures rising and drier climate transferring in, some crops that had been planted late due to nonstop rain throughout what would usually be planting season are in danger to their shallow root systems.
Extreme heat watches have been issued for a lot of the Midwest in a block stretching from southern South Dakota south by way of Nebraska into the eastern half of Kansas, based on the National Weather Service. The watches are in impact east into central Illinois and north into southwestern Wisconsin, the NWS mentioned.
Temperatures in north-western Missouri are anticipated to be within the high 90s with heat indexes from 105˚F. to 110˚F.
In southern Missouri and Illinois, index values are forecast to be around 113˚F.
An already-shallow root system is worsened as a result of the roots searching for water have a harder time pushing through dry soils, he stated. They will go into dry soils if no moisture is current. Nevertheless, it results in increased stress on the plant.
Producers must control their plants to ensure the leaves are maintaining their coloration. Soils ought to have good moisture after all of the rain the Midwest acquired the previous two months, however with heat indexes well into the 100s, and water can evaporate quickly.
