Sufficiently high yields of oats are grown on cohesive sandy soils, chernozem and peatlands. Oats better than other grains tolerate soil acidity. Saline soils are unsuitable for cultivation.

In particular, the soil micro-nano porosity (<30 m) regulates microorganism accessibility to the soil pore system and offers surfaces for organic carbon adsorption and intercalation into soil minerals.
