CropTalk: Mid-Season PFR Proven™

May 2021

Published on Monday, May 10, 2021

Planting is underway for the 2021 growing season! Moving on from the early-season PFR Proven™ products and practices discussed last month, what are the next steps to implement on your farms? The following PFR Proven™ strategies will help to protect your corn and soybean yields in the field as the growing season progresses.

SIDEDRESS NITROGEN ON CORN: In addition to applying nitrogen through a 2x2x2 system at planting, a second dose of nitrogen fertilizer made at the V3 growth stage on corn is a PFR Proven practice. Sidedressing nitrogen on corn lessens the risk of applying all your corn nitrogen needs 100% pre-plant incorporated. Making a nitrogen pass at sidedress timing has provided PFR a four-year average +$53.87 return on investment (ROI) and up to a +$72.36 ROI when applied in conjunction with planter-applied nitrogen.

FOLIAR PRODUCTS ON CORN: Feeding the corn what it wants when it needs it is key with nutritional management. Foliar feeding corn nutrition products from V4 to V5 is an insurance before the V6 growth stage. At V6, the development of corn ear size is being determined; the number of rows around the ear are set at the beginning of this stage. PFR has an array of foliar products that have shown consistent yield and profitability bumps across locations. Tissue sampling with a local lab can provide a baseline of what foliar nutritional products are best targeted for your crops’ needs.

FOLIAR PRODUCTS ON SOYBEANS: Foliar feed products on soybeans that have proven to deliver positive yields and profitability in PFR include Versa Max™ Mn and Max-IN® Ultra Manganese. Versa Max Mn contains 5% manganese and 3% sulfur. Max-IN Ultra Manganese’s formulation is composed of 5% manganese and 2% sulfur. Providing nutritional fertilizer products to soybeans before R1 (beginning bloom) gives a chance for soybeans to be adequately supplied before rapid growth takes place. Rapid growth on soybeans occurs at the R1 growth stage. This is when abundant amounts of essential nutrients are required to sustain growth. As with corn, tissue sampling can help determine a guideline for plant nutrient deficiency and sufficiency levels.

FOLIAR PRODUCT TIMING – CORN & SOYBEANS: What is a cultural practice that can enhance foliar products even more? Making your foliar applications in the morning. This PFR Proven practice refers to foliar product timings on both corn and soybeans. The ‘why’ behind this practice is that when plants’ stomata are open in the morning, guard cells have their pores exposed. This physiological characteristic could explain why products are absorbed more efficiently in the morning than at the heat of the day – when stomata are more closed.

NEXT STEPS: Once corn and soybean seeds are in the soil, caring and maintaining for your crops early in the growing season will set the foundation for a healthy harvest. For any in-season crop heath diagnostic questions, reach out to your local Beck’s sales representative, agronomist, or local PFR team member.
