Plant and Soil Nutrition

Balanced fertility and nutrient availability are critical to maximizing production. Giving your soil the proper nutrients significantly impacts the growth of your crops. We partner with quality suppliers to provide essential fertility and products to protect plant nutrients to maximize yield and reduce damage or disease.

Browse top brands and fertilizer products that help ensure your crops receive all the nutrients they need to succeed.

Our Seed Selection

Growth and development start with seed. Selecting quality seeds impacts the success of your crop and can affect critical factors such as germination rates, plant vigor, disease resistance, and yield potential. Our agronomists work with farmers throughout the region on a seed selection strategy to choose hybrids and varieties for their specific growing conditions and operation needs. We also advise on proper planting techniques to ensure optimal growth and nutrition intake.

CP5550 VT2P/RIB

5550 is a no-miss variety. Year after year, it’s at the top of our plots, including SILAGE PLOTS. Recently taking 2nd place in the Top Ag yield contest, 5550 gets up and goes out of the ground, a girthy ear with excellent test weight that stands like an oak tree. Plant at medium to high populations and, if possible, keep off the lighter producing acre.

CP5760 TRE/RIB

An exciting hybrid that will chase yield on the better acre. High response to nitrogen (good two pass nitrogen option). A low to medium population is recommended. This hybrid will flex. Fungicide is highly recommended to maximize yield potential. 5760 is stacked with the trecepta trait, giving you great corn earworm protection. Plant where your landlord can see!

CP3920E (Winpak)

For two years in a row, 3920 has taken 3rd place in our Top Ag plots with yields of 77 and 85.5 bushels per acre. Emergence and Standability are second to none while maintaining that high yield potential across all yield environments. If you want to win a yield contest, 3920 is a no-brainer.

CP4521E

4521 is a medium-tall plant with excellent emergence and standability. The plant health of this soybean makes it a broad-acre yielder. It has an acceptable disease score with tolerance to FELS, SDS, and SSC, which makes it suitable for managing nematode-prone acres

DKC 66-18 VT2PRIB

Yield Chaser Hybrid! 66-18 is no stranger to the yield book, with three top 5 finishes in the last three years across the Southern Illinois territory. Starting from the ground up, 66-18 has excellent early-season vigor with unmatched roots and stalk strength. Its semi-flex ear allows for increased population while maintaining that late-season green appearance. Keep off the lighter acre and manage disease pressure with a fungicide.

DKC 117-78 VT2PRIB

Exceptional yield performance across all soil types. 117-78 offers excellent root and stalk strength with a relaxed leaf structure, shading the rows quickly for maximum weed control. Consider fungicides to manage fungal diseases and help maximize grain fill and late-season appearance.

AG39XF3

39XF3 is a broad acre bean with the stress tolerance to go anywhere. Flies out of the ground with a canopy like a Christmas tree, 39XF3 will shade the ground for the ultimate weed control while maintaining excellent standability. Plant it in early April or late May, and watch it put money in your pocket.

AG40XF4

A new soybean to the Asgrow 4.0 lineup. Expect a yield comparison equal to its counterparts 40XF1 and 39XF3. As we are still learning about this bean, the potential is very strong, with just a few watchouts to consider. Keep off the lightest acres and avoid phytophthora-prone acres.

Crop Protection

Pests, disease, and other environmental factors can negatively impact crops’ quality and yield. Top Ag offers the leading crop protection products to help you maximize your yield potential. By selecting herbicides, fungicides, insecticides, and more, our agronomists employ the latest technology along with traditional farming practices to suggest the right agronomy products to eliminate threats to your crops.
