The new weekly report from the Agricultural Estimates System (SEA) of the Santa Fe Stock Exchange, corresponding to the period between January 21 and 27, 2026, once again focused on the impact of climate on agricultural activity in the 12 departments of the central north of the province, including Castellanos.
According to the survey, during the week rainfall that ranged between 10 and 40 millimeters was recorded, with the highest accumulated in the General Obligado department. These rains, although they were beneficial for the crops, once again conditioned the normal development of various tasks, such as the application of fertilizers, herbicides and insecticides, the chopping and bagging of early corn and the sowing processes of sorghum, cotton, late soybeans and late corn.
As for sunflowers, the harvesting process continued with different rhythms in the departments of northern and central Santa Fe. The activity was regulated by the rains, although for three or four days significant progress was made in those sectors where the physical conditions of the soil allowed the entry of machinery.
With a larger harvested area, yields began to consolidate, with values that ranged between 20 and 24 quintals per hectare as a minimum, and maximums of 28 to 30 qq/ha. In some specific plots, outstanding yields of between 38 and 40 qq/ha were recorded. Regarding pests, the report indicates a lower incidence of bird attacks, limited to some plots where herbicides were applied to accelerate the drying of the cultivars, which would allow the harvest to be brought forward and reduce losses.
On the other hand, premium corn maintained good to very good status, with excellent cultivars that managed to express their full potential. The SEA highlights that these results were favored by the adequate moisture content in the soils, the genetics used and the post-emergence nitrogen fertilization strategies.
The campaign has been carried out so far under ideal climatic conditions and no diseases or pests have been detected. Furthermore, chopping and bagging for self-consumption in dairy basins and in livestock establishments and feedlots continued at an intense pace, with yields that ranged between 12 and 13 meters per bag per hectare, reaching maximums of up to 18 m/bag/ha. The material obtained was rated as good to very good quality.
Likewise, the harvest of early corn for commercial grain began. The first data, still indicative, showed minimum average yields of 50 to 54 qq/ha and maximums of 100 to 115 qq/ha, with exceptional lots that reached between 123 and 125 qq/ha.
Meanwhile, early soybeans showed a very good evolution, with cultivars that advanced in their growth, presenting adequate structure, height, leaf mass volume and uniformity. The plots that normally went through the vegetative stage closed between the rows and began flowering without problems, favored by the environmental conditions.
For its part, second-grade soybeans completed their implementation process. The planting intention was estimated at 600,000 hectares and finally about 595,000 hectares were covered. So far, the crop has good germination and development, although sowing was delayed due to rainfall in recent weeks.
Likewise, the report indicates that the area planted with grain sorghum would be 10% lower than that of the previous cycle, which reached 132,450 hectares, due to the poor results obtained due to the water deficit in the last campaign. To date, planting progress is 99%.
As for late corn, there is a planting intention of 90,000 hectares, which represents an increase of 22% compared to the previous cycle. The process reached 80% progress, with a weekly progression of 10 percentage points, also conditioned by the recorded rains.
