The Difficulty in Winter Wheat Stand Assessments

From freak snow storms to sub-zero temperatures and on to a recent lack of moisture and a cool spring, the climate in South Dakota has left many winter wheat growers and agronomists wondering about the health of their stands.

Yellow Soybeans

Yellow soybean areas within fields are being noticed in some areas of the state. There are six factors which could be causing the soybean plant yellowing: nitrogen (N), potassium (K), or sulfur (S) deficiency, iron deficiency chlorosis (IDC), soybean cyst nematode (SCN), or yellow flash from Roundup application.

Brown Wheat Mite Affecting South Dakota Wheat

Recently, there have been reports of brown wheat mites throughout central and western South Dakota. The brown wheat mite is generally more of an issue in the drier parts of the state, or in areas experiencing drought. The feeding injury caused by these mites leaves white or brown spots that are referred to as stippling.

Factors Affecting Wheat Production Decisions: Producer survey findings

Recent USDA data shows that during the past 3 years acres devoted to wheat production continue declining in both South Dakota and North Dakota (USDA, 2018). South Dakota wheat acres experienced a remarkable decrease of 31.5% during the past 3 years, compared with a relatively mild drop of 16.4% by North Dakota.

Trade Impacts on Soybeans

Agricultural trade agreements were first established in the General Agreement on Tariffs and Trade (GATT), legal treaty signed initially by 23 nations in 1947. The purpose was to promote international trade by reducing barriers such as tariffs.

Water Use by Plant Stage

Over the growing season, solar radiation, air temperature and plant size are the dominant factors in determining evaporative demand and the rate of water use by wheat. Water use can vary dramatically on a day-to day basis, depending on climate and wheat health.

Monitoring Nutrient Status of Beef Cows

Managing cows through the winter provides different challenges compared to managing those same cows during the growing season. With snow cover, cows should oftentimes receive supplemental feed to meet nutrient requirements during late gestation and into calving season due to low forage or limited quantity.

Managing Cattle Through Winter Weather Conditions

Winter weather conditions often present challenges to cattle managers in the Northern Plains. Although we can’t alter the weather, there are management steps that can be taken to help maintain cattle health and performance.

Kentucky Coffeetree

Kentucky Coffeetree (Gymnocladus dioicus) is a medium-sized tree that will fit into many landscapes and provide interest all year with its bark, leaves, flowers, fruit and even great fall color, if weather conditions are right.

Cottonwood Galls

Just about every year I receive samples of fallen cottonwood leaves with a “bump” at the base and the first one for this year was from Winner. This is the cottonwood petiole gall formed by the feed activity of a very small green aphid.
