20.500.12556/RUL-120095 Pomen snežne odeje in nizkih temperatur v kmetijstvu The importance of snow cover and low temperatures in agriculture Snežna odeja in nizke temperature imajo ključno vlogo pri razvoju velikega števila kmetijsko pomembnih rastlin. Ekstremno nizke temperature lahko povzročijo veliko škodo ali propad rastlin, vendar določene rastline kot je sadno drevje, potrebujejo take temperature za normalno rast in razvoj. Preživetje povzročiteljev bolezni je prav tako v veliki meri odvisno od temperature. Snežna odeja deluje kot toplotni izolator, saj so pod njo temperature višje in na ta način so rastline bolj zaščitene pred ekstremno nizkimi temperaturami. Prisotnost oziroma odsotnost snežne odeje je močno povezana s stopnjo razgradnje in mineralizacijo dušika v tleh, vpliva na mikrobiološko aktivnost tal ter biodiverziteto, razvoj določenih bolezni. Zaradi vse višjih zimskih temperatur in zmanjšanja višine snežne odeje v zadnjem obdobju se veliko raziskav ukvarja tudi z modeliranjem teh sprememb in njihovim vplivom na bodočo kmetijsko pridelavo. Snow cover and low temperatures play a key role in the development of a large number of agriculturally important plants. Extremely low temperatures can cause great damage or decay to plants, but certain plants, such as fruit trees, need such temperatures for normal growth and development. Survival of the pathogenes is also largely dependent on temperature. The snow cover acts as a thermal insulator, as the temperatures below it are higher and in this way the plants are more protected from extremely low temperatures. The presence or absence of snow cover is strongly related to the degree of decomposition and mineralization of nitrogen in the soil, affects the microbiological activity of the soil and biodiversity, the development of certain diseases. Due to the rising winter temperatures and the decrease in the height of the snow cover in recent times, much research is also being done on modeling these changes and their impact on future agricultural production. snežna odeja nizke temperature kmetijstvo snow cover low temperatures agriculture true false false [M.
