01AGRONOMY
Crop rules na first estimate.
Crop traits and scoring weights na hackathon estimate from public extension guidance. Agronomist need to check dem. New combinations from the rotation search never prove well: try dem for small part of the farm first.
WETIN E MEANHow much heat, water or frost each crop fit bear, and how much each factor dey count for the score, come from general public guidance, no be from study of your region.
FOR YOUUse the scores to compare options and start conversation, no be as final judgment. If something no match your experience, trust your experience and tell the bot.
HOW WE GO CLOSE THE GAPAgronomists go check am, we go test am with farmers for real farms, and the knowledge of farmers wey get experience go enter the knowledge base wey the AI dey check.

02RESOLUTION
Satellites dey see for blocks, no be for farms.
POWER na ~50 km model grid, and one MODIS pixel (250 m) fit mix farms. CDL fit label some years wrong. GRACE na ~300 km signal: the aquifer trend for the region, no be one well.
WETIN E MEANNASA POWER climate dey describe square wey wide reach 50 km. One MODIS pixel for plants cover 250 × 250 m, so small or narrow farm fit mix with the ones wey dey near am. The USDA crop map (CDL) na satellite dem take make am too, and sometimes e dey get one year wrong. GRACE groundwater trends dey describe region wey wide reach 300 km.
FOR YOUThe climate reading dey describe your area, no be your exact plot. Small climate like valleys, slopes or frost pockets fit no show. If the crop history look wrong, correct am for the chat.
HOW WE GO CLOSE THE GAPSources wey get finer resolution like Landsat (30 m) for plants, plus the farmer’s own corrections, wey always dey come first pass wetin satellite read.

03PRICES & YIELDS
No local prices yet.
No local prices yet. “Income” na relative index plus the yield effect from trials, and the bot dey ask farmers for local prices and buyers.
WETIN E MEANFarmPartner no know your market prices or your own yields. The “income” score dey rank rotations against each other, with relative market index and the yield gain wey 3,663 field trials show after each previous crop (Mudare et al. 2025); e no be forecast for dollars or euros.
FOR YOUBefore you change crops, check local prices, buyers and contracts. The bot go ask you about dem so the comparison go show your real market.
HOW WE GO CLOSE THE GAPTo connect local price and yield data, and to learn from the prices and buyers wey farmers share for the conversation.

04COVERAGE
E deep pass for U.S., e useful for the whole world.
E deep pass for U.S.: CDL and SSURGO na only for U.S. Climate, NDVI and the forecast dey work for the whole world; outside U.S. the farmer go type dia crops and FAOSTAT go limit the search to crops wey the country dey plant.
WETIN E MEANCrop history (USDA CDL) and detailed soil data (USDA SSURGO) dey only for United States. NASA climate, plant health (NDVI), soil moisture, crop stress, groundwater trends and the weather forecast cover the whole world.
FOR YOUOutside U.S., tell the bot which crops you dey plant and how your soil be. The climate analysis dey work the same way; crop history and soil details go come from you.
HOW WE GO CLOSE THE GAPGlobal soil and crop-type datasets, so farmers everywhere go get the same deep analysis without say dem type am.

05SATELLITE TIMING
Some satellites dey answer some minutes after, and no be every day.
SMAP na 9 km grid. ECOSTRESS no dey pass at regular time, and cloud dey leave gaps. Both dey arrive 20–30 minutes after onboarding, and until then the report go list dem as “processing”.
WETIN E MEANWe dey request SMAP (soil moisture) and ECOSTRESS (crop water stress) from NASA AppEEARS for each new farm. NASA dey process dem one by one for queue, so dem dey come 20–30 minutes after the first answer. SMAP dey describe 9 km square; ECOSTRESS dey see 70 m but only for the days wey the space station pass for top, and cloud dey hide some of those passes.
FOR YOUYour first comparison dey use climate, plants and crop maps; soil moisture and crop stress go enter the report and the watering advice once dem arrive. If your soil wet or dry pass wetin the bot think, talk am.
HOW WE GO CLOSE THE GAPTo request the satellite data before time for common farming regions, and add soil-moisture products wey finer and dey come more often as dem dey available.
■ WHY WE DEY TALK THIS
Advice dey useful only if you know how far you fit trust am. Na why every answer dey come with im evidence, the data gaps and the risks wey you suppose check for your area.
■ FarmPartner dey support the farmer judgment and local agronomy experts, e no dey replace dem.Known limits for GitHub ↗
