● DATA & SCIENCE · WHERE EVERY NUMBER COME FROM

Every answer get source.

FarmPartner dey read five NASA missions, USDA farm maps, global open data, research wey experts don check and one library of farm handbooks for your exact farm — and e go tell you where each number come from, wetin e no fit see, and wetin you suppose check for your area.

01 ·

NASA Earth observation

Satellites and models for 20 years — the climate, water and plants of the farm.

MERRA-2 reanalysis · every day

NASA POWER

~50 km · 2006 → today · global · REST

Rain, temperature and how wet the soil be for root zone. FarmPartner dey calculate evaporation demand (Hargreaves ET₀), frost dates, growing degree days, heat-stress days and heavy-rain days from am.

If every rotation fit the climate, frost & heat alerts

Terra satellite · every 16 days

MODIS NDVI · MOD13Q1

250 m · via ORNL DAAC · global

How green the farm be through the year: the months wey the soil dey bare and how strong the crop be.

Months wey soil dey bare → time for cover crop

SPL4SMGP · every 3 hours

SMAP L4 soil moisture

9 km · via NASA AppEEARS · global

Root-zone and surface soil moisture now compared to the months before: “25% water by volume, e don go up from 18% for July”.

Advice on whether make you water

Evaporative Stress Index · ISS

ECOSTRESS ESI

70 m · via NASA AppEEARS · global

Actual vs potential evapotranspiration: whether the crop for this farm no get enough water, each time the satellite pass.

Crop water stress for farm level

JPL mascon RL06.3 · every month

GRACE / GRACE-FO

~300 km · 2002 → today · global

How total water storage dey change — groundwater inside — for inches every year. For the Ogallala, e dey go down.

Aquifer risk for rotations wey dey drink plenty water and need irrigation

Field & farm maps

Wetin dem plant for this exact farm, and the soil wey dey under am — USDA, na only U.S.

USDA NASS CropScape · every year

Cropland Data Layer

30 m · 2017 → 2025 · U.S.

The crop wey dey that pixel every year — wheat, sorghum, fallow… — and wetin cover the land, like water or town.

E dey find today's rotation without form; e dey reject pin wey fall for water or town

USDA NRCS Soil Data Access

SSURGO soil survey

Soil map units · U.S.

Organic matter, texture, slope, how easy e dey erode (K factor) and drainage of the farm's soil.

Erosion risk and soil-health scores

03 ·

Global open data

Forecast, places and wetin each country dey plant — so e dey work far pass Kansas.

FAO · 2020–2024

FAOSTAT crops

Every country · CC BY-NC-SA

Harvested area and yield of each crop, country by country.

Main crops wey we dey show outside U.S.; the search dey suggest only crops wey the country dey plant

Forecast · elevation · geocoding

Open-Meteo

Global · e free

7-day rain, temperature and ET₀; elevation (0.0 m mean say na open sea); town names to coordinates.

Watering, frost & heat; “I dey stay near Bilbao”

Places & postal codes

GeoNames · Census · Zippopotam

Global / U.S. county names

Pin → country offline, county names, postal codes for the farmer's country.

Research & experiments

Evidence wey experts don check and many years of field trials behind each suggestion.

Mudare et al. 2025 · Nature Communications

Crop-rotation meta-analysis

3,663 paired field trials · 1980–2024

After legume, the next crop dey yield ~23% more, ~16% after another crop; legume rotations dey reduce N fertilizer for corn and wheat by 41–46%.

📚 How much yield each option fit add

Diverse Rotations Improve Valuable Ecosystem Services

DRIVES long-term experiments

22 sites · U.S., Canada, Mexico · some since 1963

Rotations wey research stations don run for many years — corn–soy–wheat with rye or clover, alfalfa, small grains.

✅ “Dem don test am since 1981 for Lincoln, NE”

SARE handbooks · Best4Soil · UNLP · La Fertilidad de la Tierra

2,991 passages · cited by title and page

Managing Cover Crops Profitably, Building Soils for Better Crops, Crop Rotation on Organic Farms and more.

Practical how-to answers: cover crops, soil, pests

AI wey dey show source, e no dey invent

Language models dey understand the farmer; the numbers always come from the data wey dey up.

Anthropic · tool use

Conversation for the farmer's language

E dey read the question, call FarmPartner's tools (farm data, comparisons, library) and explain for simple words. E no dey ever make up number.

Claude Haiku 5.5 + web search

Fast translation · last-resort search

E dey translate the ready-made messages to the farmer's language; e dey search the web only for wetin the data no fit cover, with sources.

20+ languages, Basque inside

E dey turn WhatsApp voice notes to text for English, Spanish, Basque, Catalan and more.

Farmers fit just talk

How one number dey reach the farmer

  1. 1 · Pin

    Pin, Maps link, coordinates, postcode or town name.

  2. 2 · Fetch · ~30 s

    All the sources at the same time; slow satellites (SMAP, ECOSTRESS) dey arrive some minutes after.

  3. 3 · Derive

    Na only the features wey we calculate we dey store — rain vs ET₀, bare months, frost dates — never raw rasters.

  4. 4 · Score

    Scores wey no dey change anyhow and wey we fit explain, for today's rotation and 2–3-year options wey the search find.

  5. 5 · Explain

    Why, evidence with the source, benefits, gaps and risks — for the farmer's language.
