Depending on the area, 10 to 60% of the corn crop has been planted. Provincially corn planting is estimated at 35%. Soil conditions remain dry and friable in most areas; the lack of soil moisture is an increasing concern and has forced deeper planting especially on light textured soils. Cold temperatures and rain/snow mix has caused some concern over seed or seedling damage due to the uptake of cold water. The most vulnerable time is when the cold water is imbibed by the seed in the first 24 to 48 hours after planting. A relatively dry 14 day forecast should heighten grower’s awareness of soil moisture conservation. Avoid secondary tillage that is too aggressive (too deep, too many passes) and causes excessive drying. Packing or rolling to conserve moisture is advised.
