Weather Update – In past issues of this newsletter I have shared growing degree data from several NW & WC weather stations since April. Here is another comparison – starting on May 15 and going through August 15, found at this website. Remember, you can change the beginning and end dates and see a different date range if you wish.

In-season plant tissue testing can be useful in diagnosing nutrient deficiencies in field crops, but it must be used with caution. Extra care is needed this year given the unusual crop planting and growing conditions.

Corn rootworm egg hatch in Iowa typically occurs from late May to the middle of June, with an average peak hatching date of June 6 in central Iowa. In 2019, the average hatching date will be behind the average, due to cool spring temperatures. Development is driven by soil temperature and measured by growing degree days. Research suggests about 50% of egg hatch occurs between 684-767 accumulated degree days (base 52°F, soil).

Women’s roles in Iowa agriculture and farming continues to expand and have a significant impact on production and economics. Please join us in this free educational event held by Carroll County ISU Extension and Outreach, Mike Witt, Field Agronomist.

Interest in Cover crops has increased among producers over past years.  For some, it’s just an “old fashioned” practice viewed in a new light; for others it’s a way to provide extra livestock forage and yet others use it as a measure of extra erosion control.   Cover crops themselves are only part of a larger system to improve Soil Health-by feeding the biology living in the soil, increasing carbon matter and improving soil structure.

Agriculture and Natural Resources has many resources to help Iowans. Get a list of them all here.
