Significantly higher Nt of AF field soils compared

Liming could be a suitable measure to stabilize and raise RGFP966 and lower Al3+ content, given that lime is available at a reasonable price and that it is possible to integrate the application into the crop rotation. Since free aluminium cations adversely affect plant growth (e.g. Brady and Weil, 2014 and Fageria, 2012), farmers usually tend to attain higher soil pH values. In general, farmers apply lime to acidic soils, which is not the case in Kaule, probably due to limited availability and financial constraints.
