- Smallholder farmers making planting decisions in Ghana
- Worth noticing
- The page gives maize’s planting trigger as 20 mm of rain and says advice draws on three-day satellite estimates, plot sensors where available, and ECMWF forecasts.
Field notes
The page describes a seven-measure probe that reads soil properties including moisture, pH, and nutrients, and says it can make an on-plot decision without a network connection. For phone delivery, the instruction is designed to fit a 160-character USSD screen, with voice also offered for people who cannot read. The site says its first field test is in northern Ghana and describes the field unit as speaking Twi and English.
