# Lack of rain in Mato Grosso threatens the 2025/26 harvest - Cultivar Magazine

> Aprosoja MT has asked the Ministry of Agriculture and Conab to revise Mato Grosso crop estimates after a lack of rain forced some producers to replant. Rainfall for September to October is below the 26-year average, and planting is behind the five-year average. The association says the water shortage threatens the 2025/26 harvest.
