May 21, 2018 Iron deficiency is not as common in Illinois as other parts of the Corn Belt, particularly in states like the Dakotas, Nebraska, Western Minnesota and Northwestern Iowa due to the presence of either poorly drained or tight clay soils with high pH, and calcareous soils. Symptoms of iron deficiency are chlorotic leaves, hence the name “Iron Deficiency Chlorosis,” or IDC for short. The primary symptom of iron deficiency is interveinal... |

In recent years there has been a movement to plant soybeans earlier to take advantage of early season sunlight accumulation (building more nodes and canopy to capture more energy). Considerations for balancing the art and science: ... |

Over a decade ago I interviewed some growers in southern Illinois who double-cropped soybeans mostly after wheat. One of the things I determined was that the growers focused primarily on growing wheat and maximizing its yield and soybeans were left to fend for themselves... |

May 10, 2018 Scouting for early season soybean insect pests is beneficial in determining if your pre-planting management strategies are working as expected. Many growers are wisely choosing to treat their early planted soybean seeds with a minimum of an appropriate combination of fungicide/insecticide seed treatment product(s) because history has shown that those costly seeds can become life sustaining food for other natural creatures trying to survive in... |
