Before You Prepay for Phosphorus, Read This
Red Cedar Ag • November 18, 2025
Phosphorus prices are high. Many fields already hold a large P bank that crops cannot access. Sound Agriculture and EarthOptics help you unlock more of what you own and place new fertilizer where it pays.

Products and tools we recommend
- SOURCE® (Corn, Soybeans, Cereals): Foliar that stimulates beneficial microbes to mineralize phosphorus and nitrogen in the root zone. More availability with fewer applied pounds.
- Blueprint by Sound Ag: A field-by-field planning tool that uses your data to target where SOURCE fits and how to adjust rates.
- EarthOptics Soil Mapping: High-resolution maps for compaction, organic matter, and soil variability to guide variable-rate fertilizer, variable-rate tillage, and zone trials.
Why it matters now
- Improve P availability instead of only increasing applied tons.
- Use EarthOptics zones with Blueprint to focus inputs and stretch fertilizer dollars.
- Keep yields competitive while lowering risk on high-cost acres.
Red Cedar Ag is a proud dealer for Sound Agriculture. We also provide EarthOptics mapping services to ground-truth your plan. Contact Justin or Zachary for mapping, pricing, and a plan.

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.
