Extension Rainfall Report for August

Written by on September 29, 2022

Hardin County – During the month of August, Extension volunteer rainfall reporters received an average of 4.32 inches of rain.

The most rain for this month, 6.47 inches fell in Cessna Township as measured by Madelyn Lowery.

The least rain reported during the month, 3.03 inches was reported in Liberty Township by Phil Epley, followed closely with 3.04 inches reported in McDonald Township by Jerry Stout.

During the same month last year, an average of 2.36 inches of rain fell. The rainfall recorded in August over the past ten years averaged 3.38 inches.

For the growing season since April 15, the average precipitation in the townships was 18.49 inches, ranging from 15.83 inches in Taylor Creek Township to 21.44 inches in Cessna Township. The growing season average rainfall was 0.70 inches below the ten-year average for Hardin County through August.

August continued the pattern set in July with more than average rain to make up for a dry June. Farmers were counting on rain to complete ear fill and to produce soybean pods. Field checks in some areas of the county showed evidence of pollination issues with tip back, and also smaller ears. Soybean fields showed promise with new pod development, which could help soybean yields as soybeans tend to adapt to the weather during the growing season.

Disease pressure has been low in corn and soybean fields until later in the season. Late season moisture brought on gray leaf spot, northern corn leaf blight and tar spot in some areas, but after yield was established in corn fields. Some soybean fields have showed bacteria leaf blight later in the season. Insect pressure has been relatively low in area fields. Some corn has been chopped for silage and a few early maturing soybean fields have been harvested at the current date.

Cover crops have been seeded in the county with aerial applications and are coming good with the recent rains.
