Entressafra: what to plant between harvests

A decision-support tool for family farmers in Santa Catarina, Brazil. Mark your field on the map and tell us what you grow today (tobacco, onion, corn, soybean, irrigated rice or garlic). Entressafra shows the 3 crops that most often succeeded on that land before the next season, when to plant them and why.

How it works

• Daily NASA POWER climate data from 1995 to today: temperature, rainfall and soil moisture.
• NASA SRTM 30 m terrain: elevation, slope, aspect and lowlands, which adjust temperature and frost risk.
• 29 crops simulated in every past season: growing degree days, daily water balance, frost, heat, waterlogging, harvest rain and time to the next planting.

Em português: ferramenta para agricultores familiares de Santa Catarina escolherem o que plantar entre uma safra e outra, com 30 anos de clima da NASA e o relevo da lavoura.
