Sugarcane Aphid
The sugarcane aphid (SCA) has not been found as of yet on sorghum in Kansas. There have been a few reports of the sugarcane aphid in Oklahoma and Texas. What can we expect this season? It’s impossible to know for sure at this time, but in 2016, sugar (More)
Fertilizing Soybeans
 Compared to corn, wheat, and sorghum, soybeans remove significant amounts of nutrients per bushel of grain harvested. Nutrient uptake in soybeans early in the season is relatively small. However, as they grow and develop, the daily rate of nutrient (More)
Wheat Streak Mosaic
The severe problems wheat producers had with wheat streak mosaic virus this year can be traced back in most cases to a lack of control of volunteer wheat – especially the volunteer wheat that got started early after widespread hail damage to wheat ju (More)
Yellow Soybeans
When soybeans turn yellow at an early stage of growth, there are several possible explanations. Nitrogen (N) deficiency. In fields that have been extremely wet or extremely dry, or under severe early heat stress, rhizobial nodule development can b (More)
Sorghum Emergence
  Some fields of sorghum may have problems with non-uniform emergence for various reasons. In some cases, the surface soil was dry and some of the sorghum did not emerge immediately, or may not have emerged at all. In other cases, cool, wet s (More)
Small Predator Control
Small predator control can be a big deal for people that raise small farm animals like poultry, goats, and sheep.  Predators like coyotes and bob cats can cause a lot of dollars in damage very quickly if they are not held in check. The two best ways (More)
Controlling Marestail in Soybeans
Controlling glyphosate-resistant marestail in soybeans has been a big challenge for Kansas no-till producers in recent years. Because soybeans are generally planted later in the season, and marestail generally germinates in the fall or early spring, (More)
Weed Control Strategies in Grain Sorghum
  Severe grass and broadleaf weed pressure will reduce grain sorghum yields and can make harvest very difficult. Good crop rotation and herbicide selection are essential components of managing weeds in grain sorghum. In a wheat-sorghum-fallo (More)
Double Crop Pig Weed Control
Getting good control of Palmer amaranth and common waterhemp in Kansas has become more of a challenge in recent years. Many populations are now resistant to either glyphosate, triazine, ALS-inhibitor herbicides, HPPD-inhibitor herbicides, PPO-inhibit (More)
Soil Compaction
Conducting field work includes planting, tillage, or traffic in general. After wet weather, it can cause soil compaction, and in particular sidewall compaction in the seed furrow. The worst cases of sidewall compaction are seen after a field has been (More)
