Context In no-tillage systems, surficial lime application may induce an alkalinisation front that can correct soil acidity with depth and impact crop yields.Aims Our objective was to determine maintenance liming rates that provide the highest yield of soybean and corn in different crop rotations and to assess the speed and persistence of surficial lime application with soil depth in a no-tillage system.Methods The experiment was conducted in Southern Brazil on a clayey Oxisol under no-tillage with four lime treatments (0, 3.5, 5.7, and 11.1Mgha−1 of dolomitic lime) and three crop rotations (for grain or biomass production). Grain yield was evaluated, and soil chemical variables were annually determined on samples collected from four soil depths over 10years.Key results Soybean and corn surpassed state production levels, and grain production in winter did not compromise summer grain yield. In 10years, the alkalinisation front reached the 40–60cm soil layer. Application of lime at 5.7Mgha−1 allows for maintenance of crop yield and stable acidity levels.Conclusions In this no-tillage system, the cultivation of different winter plant species did not interfere with corn and soybean yield, lime effects in deeper soil layers, or liming need. Lime applied to the soil surface was efficient in controlling acidity in upper and deeper soil layers (up to 60cm) in soil with high buffering capacity.Implications Due to slow movement, soil samples should be collected every 4 to 5years to monitor soil acidity.

Yerba mate (Ilex paraguariensis St. Hill.) has shown a relatively high capacity for micronutrient absorption and could be a candidate for biofortification and combating a lack of micronutrients. To further evaluate the accumulation capacity of Ni and Zn, yerba mate clonal seedlings were grown in containers under five rates of Ni or Zn (0, 0.5, 2, 10, and 40 mg kg−1) with three soils originating from different parent material (basalt, rhyodacite, and sandstone). After 10 months, plants were harvested, divided into component parts (leaves, branches, and roots), and evaluated for 12 elements. The use of Zn and Ni enhanced seedling growth under rhyodacite- and sandstone-derived soils at the first application rate. Application of Zn and Ni resulted in linear increases based on Mehlich I extractions; recovery of Ni was smaller than Zn. Root Ni concentration increased from approximately 20 to 1000 mg kg−1 in rhyodacite-derived soil and from 20 to 400 mg kg−1 in basalt- and sandstone-derived soils; respective increases in leaf tissue were ~ 3 to 15 mg kg−1 and 3 to 10 mg kg−1. For Zn, the maximum obtained values were close to 2000, 1000, and 800 mg kg−1 for roots, leaves, and branches for rhyodacite-derived soils, respectively. Corresponding values for basalt- and sandstone-derived soils were 500, 400, and 300 mg kg−1, respectively. Although yerba mate is not a hyperaccumulator, this species has a relatively high capacity to accumulate Ni and Zn in young tissue with the highest accumulation occurring in roots. Yerba mate showed high potential to be used in biofortification programs for Zn.
