Understanding the Critical Role of Broadleaf Pollinator Plants in Pastures
Understanding the economic role of pollinators is the first step towards understanding their diverse values to grassland and crop systems.
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.
Sorghum Trial Results
In 2023, sorghum trials were conducted in 2 locations in South Dakota.
Noxious Weed Control in Pasture and Range
Noxious weed control in pastures is becoming more of a challenge. Most ground commercial spray businesses are no longer spraying pastures. If they are, there may be restrictions on the time they will spray, what products they will spray, or they may only spray if they also have all of the rest of your spraying business.
Spring Wheat Variety Trial Results
The 2023 spring wheat reports include data from 10 locations with regional summaries.
Field Pea Variety Trial Results
In 2023, field pea trials were planted at different locations in South Dakota.
Lawn Weed Control
Cultural weed control practices must be included in weed management programs to optimize control and inhibit re-infestation. A healthy, dense turf cover is the best overall defense against weed invasion. Some common cultural weed control practices include planting the most adapted turfgrass species for your environment (i.e. shade, full sun, or hot, dry conditions), maintaining a mowing height of 2.5–3.5 inches, watering deeply but less frequently, and proper soil maintenance including fertilization and core aerification.
Grassy Weeds
Grassy weeds are a problem in all field crops. They must be identified at early stages of growth so they can be controlled before crop yields are seriously threatened. Control measures are not the same for all grassy weeds, so accurate seedling identification is important.
2017 Weed Control: Pasture and Range
There are 24 million acres of native and tame pasture and range as well as 1.4 million acres of grass hayland in South Dakota.
