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.
