Soybean Replanting Decisions

-Understanding the cause of an inadequate soybean stand is important to help prevent a reoccurrence of a poor stand if the decision is made to replant. -Final soybean plant stands of 73,000 plants per acre or more consistently provide 90 percent or more of maximum yield potential. -Make weed control a high priority in fields…


Chloride & Sodium Toxicity in Soybean

– Soybean productivity can be significantly hampered by toxic elements. – Plant toxicity normally occurs when certain ions in irrigation water are absorbed and accumulated at high concentrations in the leaves. -Excessive levels of chloride (Cl) and sodium (Na), which can be found in the irrigation water, are considered toxic ions and can damage the…


Uneven Early Season Growth in Corn

Several factors can contribute to uneven corn emergence and growth early in the season. Replanting is not often justified due to uneven stands; however, understanding why uneven emergence occurred can help minimize the risk in the future. Additionally, consideration should be given to how uneven early growth can affect the implementation of some management tools…


Managing Nematodes in corn

 When left undetected and untreated, nematodes can significantly reduce corn yield potential. Symptoms of nematode feeding can easily be misidentified as herbicide injury, soil compaction, sandy soils, and other problems. Corn growers should pull soil samples from low performing areas of fields to determine whether or not nematodes are present. The evaluation of samples taken…


Waterhemp Species

Abutilon-theophrastiAlthough native to the U.S., waterhemp was not considered a major agronomic problem until the 1980’s-reduced tillage systems, herbicide-resistant biotypes, and simplified weed management programs contributed to its increased prevalence.
