    In these uncertain times, having plans in place for your cropping practices is more important than ever. Having a plan saves time and money, and it may also help to mitigate the stress and anxiety that inevitably arises from living through the unprecedented situation of the global COVID–19 pandemic. If you haven’t developed an approach for getting your crop plans recorded, Maizex would like to help with our easy-to-use crop planning tool, which covers maturities from 82–110 day corn. It is also a great way to start record-keeping with year-over-year planning in mind. After all, it can be difficult to remember come harvest time where trials/hybrids were planted if you don’t have it written down or recorded electronically. Not only will the Maizex crop planner help you keep track of where hybrids and trials are going, but it can also be a great tool to have in the field with you for checking plant populations or recording what herbicide or fungicide options you want to deploy.

    The Maizex Crop Planner is an incredibly helpful resource. Each section is colour-coded with its corresponding “cheat sheet” to help you fill in the crop planner and make some informed cropping decision. It includes the following valuable information to assist you in making the best decisions possible to improve your productivity and profitability:

    • Hybrid Intensive Management Score and Target Populations
    • Relative Maturity vs CHU
    • Corn Plant Population Row Length Based on Row Spacing
    • Foliar Fungicides for Ear Rots
    • Insecticides for Western Bean Cutworm
    • P and K Removal Based on Yields
    • P and K Recommendations Based on Soil Tests
    • Safe Rates for Banded Fertilizer in Corn
    • Nitrogen Rate Considerations
    • Herbicide Information

    Perhaps the best thing about the tool is that all the summaries and important tables are in one place, making it a quick and easy reference tool that can provide guidance at a glance.
