Turn Soil Tests Into Client Value

Our methodology is built on agronomic evidence, documented nutrient values, & tax-defensible standards. We focus strictly on fertilizer-equivalent nutrients that are verifiably present, still plant-available, & supported by soil tests—nothing theoretical or inflated. Different providers use different assumptions, often including background soil levels or applying aggressive nutrient-measurement models. We don’t. We price nutrients off real market data, tie values to actual fertilizer management practices, & ensure every estimate can hold up under professional review. If a number can’t be supported with sound agronomy and tax law, we don’t use it.

You can cancel anytime. No long-term commitments, penalties, or hidden terms. Your access remains active through the end of the billing cycle, and there are no extra steps or conditions to leave. The subscription is designed to be flexible and predictable.

It’s an organized reference library covering the agronomy, tax foundations, and practical workflows behind residual fertility. You’ll find IRS code summaries, soil science fundamentals, valuation logic, case studies, checklists, and guidance for common scenarios brokers, CPAs, & bankers run into. Content is added regularly, and if a topic is missing, we document and publish it.

Instant estimates are designed for marketing purposes and internal decision-making—they’re based on our standards and data, but they are not certified or suitable for IRS filings. For tax documentation, you need an agronomist-certified report. Those reports are reviewed by a professional agronomist, supported by full documentation, and prepared to withstand professional or regulatory scrutiny. If the goal is audit-ready support, use the certified report.

Basic and Professional plans are for individual users only. Enterprise allows the highest estimate volume and is required if you want multiple team members to log in or collaborate. Need to upgrade? Just let us know and we'll adjust your access.

We serve clients in all 50 states. Our agronomic models and fertilizer price index cover every major cropping region in the U.S.—with the most robust data for the Midwest, Great Plains, California, and the Delta. If you operate in a unique or specialty area, we apply trusted agronomic principles and draw on the most relevant regional or national price data, so your estimates always reflect the real market and field conditions where your property is located.

Agronomist-certified reports: Typical turnaround is 2–3 wks depending on completeness of the soil data and project scope. If information is missing or unclear, we’ll let you know before work begins. Rush support is available when feasible.
