South-Central ND

During the past week (May 12 to 18), the south-central regionís rainfall ranged from 0.16 inches at Robinson to 1.03 inches at Streeter as recorded at NDAWN (North Dakota Agricultural Weather Network) sites. Most of the area received one-third to one-half inch of rain. Topsoil moisture generally is adequate but the subsoil has additional water-holding capacity. The regionís average soil temperature at the 4-inch depth ranged from 54 to 64 F on May 18.

The regionís cool-season crop and corn planting is essentially complete. Wheat is at the 2.5- to 3-leaf stage with April 15 planting date and 1- to 1.5-leaf stage with May 1 planting. Corn planted during the last week in April has emerged. Soybean planting continues, with about 50 to 75% of the acreage completed. Dry bean and sunflower planting also has started.

The regionís daily low air temperatures recorded by NDAWN during May 13-14 ranged from 23 to 30 degrees F. Emerged corn had leaves killed but plant regrowth is occurring. Minimal or no injury has been observed or reported on cool-season crops.

POST herbicide spraying for wild oat and early-emerged broadleaf weeds in small grain has started. Weed emergence and growth is expected to accelerate with recent rainfall and warmer air temperatures. Farmers are considering fungicide tank mixtures with herbicides on tillering wheat.

Northeast ND

Last weeks precipitation amounts of 1" along highway two to 3", mostly as snow, in northern areas stopped field work May 11. Field work begin again over the weekend in lighter precipitation areas. May 19 rain has again stopped field work. No field work was possible in northern regions this last week. About 20% of small grains acreage is left to be planted and 50% of the Canola is yet to be planted in Cavalier, Towner and Rolette Counties. Very little crop or weed growth last week due to extreme cold. Temperatures in the low 20's resulted in only minor damage as most crops have not emerged yet. Alfalfa tops were frozen and scattered reports of frost injury to Canola were reported. Winter wheat looks good. Earliest planted wheat and barley is in the1 to 2 leaf growth stage. Cold soil conditions is elevating concerns for untreated soybean seed that has been in the ground for two weeks in some cases. Corn, generally, has not yet emerged. Some wild oat emergence has occurred.
