“…Перечисленные выше процессы цикла углерода приводят к формированию органо-профиля почв, который представляет собой определенную последовательность генетически связанных горизонтов аккумуляции и трансформации органического вещества. В ЕГРПР (2014) основные органо-генетические горизонты почв включают: поверхностный органический -O (подстилки, торфа), гумусово-аккумулятивный -A 1 и гумусово-иллювиальный -Bh. Различные почвы характеризуются специфическим набором органо-генетических горизонтов.…”

The carbon balance in forest soils (CBFS) was studied on the basis of the geostatistical process model “BIGIN” (Biosphere Greenhousegas Inventory). Warming in boreal forests in the baseline period (1990 ± 5 yr.) initiates a shift in the CBFS towards its decrease, i. e. CO2 source. In the horizon “O”, the decrease in the CBFS is minus 101.4 MtC. The warming of the climate by 1.5 °C and 3 °C will cause a further decrease in the CBFS by 345.7 MtC and 691.4 MtC, respectively. In moderately warm forests, climate warming initiates the formation of a positive CBFS, i. e. CO2 sink. In the horizon “O” of the soils of moderately warm forests, climate warming in the baseline period and in the future leads to the development of positive CBFS, i. e. CO2 sink of 62.4 MtC, 212.8 MtC and 425.4 MtC, respectively. Positive changes in the CBFS in boreal and moderately warm forests in the studied range of climatic temperatures were noted in the horizon “A1” (7.3 MtC, 24.9 MtC and 49.8 MtC) and the horizon “Bh” (14.1 MtC, 48.0 MtC, 96.2 MtC). Climate warming initiates a total negative CBFS (minus 17.6 MtC). Further warming of the climate by 1.5 °C and 3.0 °C will lead to a decrease in the CBFS by minus 60.0 MtC and minus 120.0 MtC. In terms of CO2-equivalent, this will amount to 4%, 13% and 27% of the total country annual emission in 2020. Negative CBFS is not an indicator of emission strengthening. The final conclusion about CO2 source/sink can be made only when analyzing the forest ecosystem when conducting a coupled soil-stand analysis. The error in the estimation of the CBFS in the soil organic profile in the baseline period is ± 23.0 MtC at a confidence level of P = 0.67 and ± 47 MtC at a confidence level of P = 0.95. With an increase in temperature by 1.5 °C, the error will be ± 80.0 MtC and ± 160.0 MtC at confidence levels of P = 0.67 and P = 0.95 respectively. The magnitude of the error will be ± 160.0 MtC and ± 320.0 MtC at confidence levels P = 0.67 and P = 0.95 respectively with an increase in temperature by 3.0 °C.

“…Ruski strokovni in v znanosti uporabljan izraz je počva /почва, medtem ko je zemlya/земля široko uporabljan izraz za zemljišče, posestvo, rusko zemljo kot nacionalni teritorij, … itd. Zemlya je ime planeta (Stolbovoy, 2012). Hrvatje in Bosanci v strokovnem izrazoslovju dosledno uporabljajo tlo za tla, posebej še v kontekstu tretje dimenzije (torej talni profil).…”

Skrb za natančno in bogato izrazoslovje, tako poljudno in predvsem strokovno, je nujen in pomemben prispevek k razvoju in pestrosti materinega jezika. Pri rabi strokovnih izrazov se pogosto soočamo z različnimi interpretacijami in nepotrebno pestrostjo izrazov. To praviloma ne prispeva h kakovosti jezika in prej kaže na premalo skrbno izrazoslovje, na pomanjkljive oz. strokovno neustrezne opredelitve in/ali spregledan izvorni pomen posameznih izrazov. Strokovni izrazi morajo biti nedvoumni in ne smejo dovoljevati različne interpretacije, pomena. Raba in uvajanje poljudnih izrazov v strokovno izrazoslovje je prisotno tudi v izobraževanju. Primer takih zadreg v pedologiji je tudi raba besed 'tla' in 'prst'. Na prvi pogled sicer obrobna tematika ima širšo in pomembnejšo dimenzijo. Zmeda v strokovnem jeziku se namreč pojavlja tudi v prevodih evropske zakonodaje. Tako slovenske verzije nekaterih EU dokumentov mestoma zaradi neustreznih in pomensko dvoumnih oz. zgrešenih prevodov ne odražajo pravega pomena izvornih besedil. To predstavlja zadrego, ki jo je potrebno urediti. Prispevek predstavlja terminološke nedoslednosti v pedološkem izrazoslovju, pojasnjuje in utemeljuje razloge za rabo osnovnih izrazov s področja tal, osvetljuje ljudski pomen besed 'prst' in 'zemlja', primerja s stanjem v drugih jezikih ter nakazuje ustrezno rabo nekaterih ključnih izrazov v strokovnih/znanstvenih besedilih, za potrebe prevajanja in pedagoškega procesa.

Soil organic carbon sequestration according to two Geoset long-term field experiments in the Moscow region

et al. 2020

The feasibility of implementing the "4 ppm" initiative, which assumes an annual increase in organic carbon stocks of agricultural soils in the layer 0-40 cm, was estimated with the dynamic carbon model RothC in two long-term DAOS experiments in the Moscow region, conducted in neighbouring fields for 74 and 76 years. Treatments included absolute control, application of organic, mineral, organic and mineral fertilizers at increasing rates. One of the experiments showed the growth of C stocks 12‰ in the layer 0-20 cm in the first 20 years in treatments with mineral fertilization, and 17‰ with the additional application of manure in an average annual rate of 10 Mg·ha-1. The accumulation of C allowed increasing its stock by 18-25%. Still, with the subsequent decline in crop rotation productivity, there was a loss of part of the previously accumulated C. In another experiment, at close values of annual C input, there was a loss of initial C stock due to the history of land use. The crop rotation adjustment provided a 3-8 ‰ increase of soil C in the 0-20 cm layer in the first 20 years after introduction but was insufficient to match the "4 ppm" initiative. In the long term, the organic fertilizer system had an advantage over the mineral one in ensuring the stability of organic C stocks in the arable layer. However, the management of C sequestration was complicated in the non-equilibrium state of the carbon system "plant residues-organic fertilizer-soil".
