Meet Sales Agronomist Derek Penzkover

Red Cedar Ag • March 1, 2026

Welcome to the Team, Derek

Derek Penzkover joins the RCA team as a Sales Agronomist, bringing both strong agronomic training and hands-on field experience in Wisconsin. Originally from the Blue Hills of Rice Lake, WI, Derek studied Soil Science at UW–Stevens Point, where he developed a passion for the science, complexity, and work ethic that drive agriculture. He comes to RCA from AgGrow Solutions in Custer, WI, serving growers across the Central Sands with a focus on practical recommendations that perform in the field.


Derek is excited to be part of RCA because of the team’s innovative mindset and commitment to making management and product placement decisions grounded in solid data, always aiming to deliver the best ROI for the grower. Outside of work, he enjoys hunting, fishing, cross-country skiing, and running. He is married to his wife, Carolyn, and they’re proud to call Wisconsin home. 

Derek is looking forward to building relationships with growers and helping them make confident, results-driven decisions season after season.

Specialized potassium transport genes and elevated populations of K-solubilizing microbes indicate the soil system is under potassium limitation, even when standard soil tests may not flag a deficiency. This microbial response reflects low exchangeable K, triggering biological mobilization of mineral K to sustain plant and microbial growth. When these signals appear, looking for a highly available potassium source that directly impacts the crop rather than soil applied is recommended. Our Solution: NanoBond Ka: Potassium Acetate with Nanotechnology NanoBond™ Ka by Yield Innovations is a potassium acetate product powered by NanoBond™ 4Z nanotechnology, designed to efficiently build plant potassium levels as part of a The Agronomic Profit System. Because potassium acetate stays soluble with less soil moisture, it can help keep K available in drier conditions compared to traditional potash sources, supporting stronger nutrient uptake and overall plant function. It is positioned for foliar, in-furrow, and UAN applications (2x2, sidedress, Y-drop), with a 0-0-25 analysis derived from potassium acetate. Contact RCA for more information.
