Documenting the Need for Potassium in Uruguay
Agriculture in Uruguay initially developed in high potassium (K) soils, under conventional tillage and crop rotations that required no K fertilizer. The scenario changed during the last decades driven by increasing grain prices. The annual cropped area tripled between 2002 and 2014, with soybean now sown on 67% of the area. Cropping systems have intensified, shifting from crop-pasture rotations to continuous annual cropping under no-till cultivation.
