Organic matter humification is a process conducive to the soil since thanks to it organic matter resources increase and as well as soil nutrient stocks available for plants.
The main soil-forming process in Rendzic Leptosols is humification and subsequent removal of carbonates.
The [C.sub.FA] was calculated as the difference between [C.sub.EX] and [C.sub.HA] x Humification index (HI = [C.sub.HA]/SOC) and polymerisation index (PI = [C.sub.HA]/[C.sub.FA]) were calculated according to Abril et al.
As can be seen from Table 2, the humification levels were significantly higher in the R2 and R3 treatments than in the other treatments (p < 0.05), and, as shown in Figures 3 and 5(a), the behavior of the temperature and changes in the water states at the same time were also more beneficial to composting in treatments R2 and R3 than in the other treatments.
The increase in microbial biomass is determined by the water and nutrient availability in the soil, mainly by the presence of the organic substrate (Diogenes et al., 2013) and plays an important role in mineralization and humification of organic matter (Figueiredo et al., 2012).
In the light of global change scenario, soil humification mechanisms have acquired renewed interest.
The results showed some variability in soil processes of humification and formation of the cambic horizon on different parent materials.
In this case, the reactions involved in humification, and thus in the conversion of compounds into more refractory forms, would have been favoured by bacterial consumption of the low molecular weight DOM.
due to peat depth or peat quality such as humification, aeration or water content).
Evidently, the sharp increase in the NaOH-P fraction at treatment with concentrated NaOH was caused by the humification of organic matter within the sample.
Because the C:N ratio in woody litter is so high, the humification of fine woody debris may also he an important component of N retention by organic matter.
