Humic acids. VIII. Characteristics of humic acids in soil.



Humic acids. VIII. Characteristics of humic acids in soil.



Z. PflErnahr. Dung 71: 33-57



An experimental study, including brief reviews with 64 references, comparing the physical and chemical behaviour of humic acids, isolated from black earth and podzol, precipitating in NaOH and NaCl (G fraction = "grey humic acid") and remaining in suspension (B fraction= "brown humic acid").
