Plan the season, not just check it
The crops above are gathered from every district in Diffa, and the ground under them is not all the same. Your own soil, slope and rainfall will shift the dates — the Divisi app works them out for your field, and dates each job that follows.

Planting windows shift with the forecast. Leave your email and we'll send what changed, and a note when planting time nears — a couple of emails a month at most.
Frequently asked questions
Is there a farming app that works in Diffa?
Divisi does. It reads Diffa's own rainfall, soil and terrain rather than a national average, so the planting dates and crop shortlist on this page are the same ones the app works out for a field here — then dates each job for that field, and keeps working with no signal.
Is this exact for my own field?
No — these are readings taken across Diffa, not on your field. Soil, slope and rainfall change from one farm to the next. Check your own location to see your own numbers.
