The quality of silages made from raw potatoes preserved preliminary with sulphuric, hydrochloric, phosphoric and formic acid and with the Acidol preparation was compared with that of silages made in acid whey. The period of ensiling whole tubers in whey pickle is approximately fourfold longer than that of ensiling tubers without peel and/or cut tubers. Tubers cut into pieces are ensiling as quickly as suedes, beets, pumpkin or cabbage. In the whey pickle tubers damaged during harvest and tubers infested by dry rot can be ensiled. This ensiling way is not suitable for tubers heavily infected by soft rot. Silages made from raw potatoes preserved with acids have got the estimates from bad to statisfactory. The quality of silages made in whey pickle was good or very good. Potatoes ensiled in whey contain a very low amount of butyric acid and are willingly eaten by pigs.
Decomposition in soil is crucial importance in biogeochemical cycling and ecosystem functioning, because soil organic carbon (especially in northern forest ecosystems) is large potential source of CO₂, a greenhouse gas. The stability of the stored carbon under changing climatic conditions has been the subject of recent concern due to the expected climate warming, which is predicted to be most pronounced in northern regions. Temperature is a primarily factor affecting on decomposition processes of organic matter in soils, so temperature response functions are central to models simulating the effects of global warming on the mineralisation of soil carbon pools. The relationship temperature-decomposition rate is complicated, because there are many factors which affect on, for example soil moisture, biogens access for microorganisms and other. There are important and very intensive studied recently problems. Also numerous studies have been specially devoted to soil biota, mainly soil microorganisms.
