The Mato Grosso Soybean and Corn Producers Association (Aprosoja MT) warns that the soybean harvest in Mato Grosso for the 2025/26 crop has been marked by climatic challenges, mainly due to the excessive rainfall recorded in recent weeks. According to the Mato Grosso Institute of Agricultural Economics (Imea), as of February 6th, 39.61% of the planned area had already been harvested in the state, an advance of 11.03 percentage points compared to the previous week.
Over the past fifteen days, rainfall totals have ranged between 90 mm and 150 mm in various producing regions. This excess moisture is a concern for producers. According to the president of Aprosoja MT, Lucas Costa Beber, the high volume of rain directly impacts field operations and could compromise the final quality of the crop.
“Excessive rainfall is hindering harvesting operations, making it difficult for machinery to access the fields, and can cause weight loss and reduced grain quality. Furthermore, soybean planting occurred over a longer period, which should result in a later harvest in some regions, also impacting the ideal window for the second corn crop,” the president points out.
The administrative director of Aprosoja MT, Diego Bertuol, also highlights that delays in planting and, now, in harvesting have made it difficult for producers to fulfill previously signed contracts. According to him, this scenario compromises cash flow at the beginning of the harvest, a strategic period for the financial organization of the farms. “With the delay in delivering the production, many producers face greater difficulty in honoring commitments and organizing the finances of the harvest, which has a direct impact on the economic sustainability of the farms,” he points out.
Another point of concern is the increased pressure from pests and diseases in later-cycle areas, such as stink bugs, whiteflies, and Asian soybean rust, factors that can compromise final productivity, especially in crops harvested later in the harvest window. In Vera, farmer Sandro Mick reports that the situation is challenging and requires difficult decisions daily. According to him, while some producers have already harvested about 80% from the area, others still have approximately half of the production in the field and are facing difficulties in moving forward.
“Since Sunday, nobody has been able to get machinery into the fields. The soybeans are opening their pods, sprouting, and producing damaged grains. When the weather clears up and the sun comes out, we can harvest, but it's soybeans with high moisture content, close to 30%. If left in the field, they will shatter, sprout, or rot. Since we don't have storage facilities, there are no good decisions; they are all bad. We are harvesting even with 30% moisture to avoid greater losses,” he reports.
Sandro also explains that the delay in starting the planting season contributed to the current situation. “It rained a little in September, but we were unable to plant until October 8th. When the rain returned, we were already behind schedule and accelerated the planting. Now everything has arrived at harvest time, which makes the situation even more complicated.”
The report highlights the pressure faced by producers, who need to take advantage of every window of dry weather to minimize losses and maintain the quality of production. Corn planting has already reached more than 281 TP4T of the planned area, a higher rate than that recorded in the same period last year. However, the trend is for the pace to slow down in the coming weeks, following the possible delay in the soybean harvest in some regions. Weather projections indicate accumulated rainfall between 65 mm and 95 mm for parts of the state next week, which may temporarily limit the progress of the machinery.
Given the current scenario, Aprosoja MT reiterates that it continues to closely monitor the progress of the harvest in all regions of the state. The moment demands caution and planning from producers, who face operational and phytosanitary challenges in the final stretch of the cycle, while awaiting improved weather conditions to ensure the advancement of work in the fields.
