Farm Audit Tool: Instant Satellite, Soil & Land Monitoring
Turn coordinates or field parcel boundaries into a structured land-screening summary. AgriAuditor cross-examines multispectral satellite imagery, global soil horizon diagnostics, NASA SMAP root-zone hydrology, 3D contour terrain models, and 220+ crop economic benchmarks to help you compare agricultural options before commissioning local tests or professional review.
What the AgriAuditor Land Audit Evaluates Across Every Parcel
Every audit runs a multi-layered diagnostic check across five independent scientific data providers.
Multispectral Satellite Remote Sensing
Sentinel-2 Bottom-of-Atmosphere (BOA) 10m multispectral analysis. Screens canopy vegetation vigour (NDVI), canopy water stress and drought vulnerability (NDMI), chlorophyll absorption and active nitrogen uptake (NDRE), and high-resolution natural True-Color RGB surfaces.
Global Soil Horizon Diagnostics
Deep soil stratification from ISRIC SoilGrids at 250m resolution across the top 0–30cm root zone. Extracts topsoil pH in H2O, Soil Organic Carbon (SOC), total Nitrogen stock, Cation Exchange Capacity (CEC), and depth to bedrock, with support for local lab-test overrides.
NASA SMAP Root-Zone Hydrology
Microwave radiometer soil moisture tracking from NASA SMAP. Evaluates 0–100cm root-zone saturation, surface water saturation deficits, drought recurrence probabilities, and seasonal irrigation replenishment needs calibrated against historical ERA5 reanalysis data.
3D Topographic Contour & Drainage
Interactive 3D elevation digital elevation model (DEM) with adjustable vertical exaggeration (1x to 5x). Calculates slope gradient percentages, identifying erosion-prone inclines, natural water runoff lines, and frost pockets that settle in low-lying depressions.
220+ Crop Viability & Gross Margins
Screens 220+ specialty, orchard, vineyard, vegetable, and broadacre row crops. Matches heat units (GDD), chill hours, pH envelopes, and water requirements, then calculates transition CAPEX, operating costs, break-even yields, and projected gross margins.
Decision-Support Land Summary
Creates a decision-support summary combining soil indicators, vegetation anomalies, downside scenarios, and relevant agricultural subsidy opportunities (USDA EQIP, ARC/PLC, EU CAP) for review by growers, agronomists, buyers, and finance teams.

| Rank & Crop | Bio-Suitability | Attainable Yield | Benchmark Revenue | Estimated Gross Margin |

| 3. Oats (Spring) | 88% (Good) | 84 bu / acre | $336 / acre | +$112 / acre |
| 4. Alfalfa Hay | 86% (Good) | 4.2 tons / acre | $756 / acre | +$278 / acre |
How to Run an Instant Farm Land Audit
Four steps from coordinate entry to a structured agricultural screening result.
Define Parcel Location
Type an address, enter decimal lat/lon coordinates, or draw your exact field boundaries directly on the interactive satellite map.
Set Farm Assumptions
Enter total acreage or hectares, currency, experience level, target annual profit, and any existing soil test reports to override default estimates.
Execute Instant Audit
Select 'Run Audit'. The engine queries Sentinel-2, SoilGrids, NASA SMAP, and 220+ crop matrices via real-time streaming calculation.
Review Results & Export
Inspect 3D slope contours, canopy health indexes, limiting soil factors, and economic budgets. Export to PDF for further review.
Frequently Asked Questions About Farmland Audits
Common questions regarding satellite resolution, soil accuracy, guest tiers, and agronomic methodology.
What does the AgriAuditor Land Audit evaluate for a parcel of farmland?▾
The AgriAuditor farm audit evaluates parcel geometry, multispectral satellite vegetation vigor (Sentinel-2 NDVI, NDMI, NDRE), physical and chemical topsoil stratification (SoilGrids 250m: pH, organic carbon, total nitrogen, CEC), NASA SMAP active root-zone soil moisture, 30-year historical climate reanalysis, 3D elevation contour hydrology, and biological/economic viability rankings for over 220 commercial crops.
What is the spatial resolution of the satellite and soil monitoring layers?▾
Multispectral vegetation indices (NDVI, NDMI, NDRE) and True-Color RGB imagery are sourced from the European Space Agency Sentinel-2 constellation at 10-meter to 20-meter pixel resolution, refreshed every 3 to 5 days under cloud-free passes. Global soil profiles are derived from ISRIC SoilGrids at 250-meter resolution across 0–30cm depth. Root-zone soil moisture is calibrated via NASA SMAP at 9-kilometer to 1-kilometer downscaled resolution.
How accurate are the mapped soil estimates compared to a physical laboratory soil test?▾
SoilGrids provides spatial machine-learning screening estimates based on thousands of soil profiles and environmental covariates. These estimates are useful for initial regional screening, but they do not replace a physical laboratory core sample. AgriAuditor allows growers to override mapped pH, nitrogen, and organic carbon with their own accredited laboratory soil test results.
Can I test custom financial constraints like equipment capex and labor wages?▾
Yes. The audit control panel includes an advanced farm business profile where you can define minimum annual profit targets, operator wages, annual business overhead, available investment capital, and maximum payback periods. The engine cross-references these against real crop establishment costs (transition CAPEX) and operating budgets.
How many free land audits can I run as an anonymous visitor?▾
Anonymous guest visitors can run up to 2 complete parcel audits for free without creating an account. Creating a free AgriAuditor account grants 5 new-location audits each month plus one active monitored field. The Grower plan provides 50 audits per month under fair use and 25 active monitored fields.
How does AgriAuditor determine which crops are most viable?▾
Viability is calculated using fuzzy agronomic envelope matching across five critical dimensions: thermal requirements (base temperature and growing degree days to maturity), seasonal water requirements vs. rainfall and irrigation, soil pH tolerance bounds, winter chill hours / frost windows, and slope/drainage tolerance. Biologically viable crops are then ranked by gross margin per hectare and net profit potential.
