Harvest wheat early and use artificial drying. Wheat harvested before repeated drying and re-wetting can also result in more harvested bushels and a higher quality product with higher test weights. No-till soybean immediately after harvest. Conservation tillage, particularly no-till, preserves valuable soil moisture for a double crop. For best results leave the tillage tools in the shed and chase the combine through the field with a no-till planter or drill.
Narrow rows favor quick canopy closure to help preserve soil moisture and compete with weeds.
If you don't already plant or drill 15-inch rows or narrower, consider doubling back with the planter. Irrigate the second crop so that the growing season starts as soon as you plant. If irrigation isn't available and the soil moisture isn't there, don't plant a second crop in the northern extremes of the double cropping region of Missouri. The growing season clock is ticking and the seed is just sitting. Residue management is very important under a no-till management system, especially when planting a double crop into fresh residue.
