Results of a research project on optimizing irrigation methods by utilizing thermal and multispectral center pivot sensors to gather crop data.
Figure 1. Early installation of sensors helps to minimize root and leaf damage and makes it easy to get around the field with the pickup or ATV to install the equipment.

This free tour will provide an opportunity for individuals interested in interseeding cover crops to view interseeded corn and soybean fields at several locations across Nebraska.
Figure 1. In 2019 in York County (left), the grower built his own interseeder and tested a nitrogen mix (4 lb/ac crimson clover, 3 lb/ac red clover, 2 lb/ac yellow sweet clover, 4 lb/ac Winterhawk annual ryegrass, 1.5 lb/ac impact forage collards, 1.5 lb/ac Trophy rapeseed) vs. diversity mix (2 lb/ac red clover, 2.5 lb/ac Hubam white seed clover, 4 lb/ac Winterhawk annual ryegrass, 1 lb/ac purple top turnip, 3 lb/ac golden flax, 0.5 lb/ac phacelia Angelia, 0.5 lb/ac chicory) interseeded at V5-V6 corn vs. check treatment. Seward County (right), a Hagie was used to broadcast interseed 10 lb/ac red clover and 5 lb/ac buckwheat into V6 corn vs. check treatment.
