Reference soil MY052: Humic Podzols
A humus podzol on old coastal ridge (4th succession from coast, 6 m above high tide level), mainly derived from adamellite (biotite granite and granodiorite), subordinately from metamorphosed pellitic rocks, greenstones and cherts. Rootlets are only observed to 26 cm. There are humus stains in A2, extending to thin bands of humus stained sand (7.5 YR 5/2) with colour intensifying with depth. At 96 and 106 cm there are dark reddish brown (5 YR 2/2) placid horizons of 5 mm thickness, weakly cemented. B2C is slightly micaceous. The soil is extremely poor, and the cultivation of crops is only possible if all nutrients are supplied by fertilizers. (additional climatic data: days with precipitation >0,1 mm)
