16. County-wide Agricultural Impacts for the week
Climate Division
Drought Impact by counties
1: North-West
2: North-Central
Rolette: Severely Dry. Pastures are bare. Producers are looking at weaning early. Creep feeders are being put out to supplement the calves. Feeding hay will start early. No moisture to plant cover crops or crop aftermath to germinate.
McHenry: Severely Dry. Moisture has been hit and miss all year and with extreme temperatures some area are in dire straits. Poor to scarce hay crop and conditions have been hard on the corn and soybean crops. There are producers feeding hay out in their pastures. Some producers have pulled animals out of pastures that no longer have adequate water supplies. Looking for other feed stuffs.
3: North-East
Pembina: Severely Dry. Deep cracks in most fields. Cattle guys are starting to bring cattle in because pastures are bare.
4: West
Mercer: Severely Dry. No rain last month. Temp above 90F for many days. Corn, sunflowers, soybeans are greatly affected by dry conditions cob, pods and heads are not filling, at least to this point a 30 to 40% reduction in yield. No regrowth occurring if not on a rotational grazing system, pasture greatly showing drought impact.
Dunn. Moderately Dry. Lack of Rain, dry vegetation has high fire danger. Pasture and Range are dry and being used up.
5: Central
Eddy: Moderately Dry. Has not rained in nearly 2 months in the majority of Eddy County. The very Eastern end of the county received its last rain well over a month ago. We started the spring with a moisture shortage stemming from last year and received just enough moisture during the first part of the growing season to keep the early crops looking good. When the rain stopped the beginning of July, things went backwards quickly. With the hot conditions and great demand for moisture from a maturing crop there is no soil moisture left. Corn is being chopped over a month sooner than normal. Many soybean fields have lost their leaves. Some corn fields will be close to harvest moisture in the next week or two if there is anything worth combining. Lawns are brown and some producers are considering starting to feed hay. Pastures are brown. No regrowth has taken place after cattle removed over a month ago.
6: East-Central
Griggs: Moderately Dry.
7: South-West
Slope: Moderately Dry.
8: South-Central
9: South-East
McIntosh: Mildly Dry.
Logan: Moderately Dry.
LaMoure. Moderately Dry. We've received a small amount of rain this week but it’s not enough to help much.
