Agro-phenological response to climate development in past and present

Popis výsledku v původním jazyce

This paper consists of two parts: i. analysis of phenological data ii. calculation of the protective effect value of vegetation. Crops with low ground cover were analysed i.e. maize, potato and sugar beet. Phenological data were obtained from direct phenological observations of the Czech Hydrometeorological Institute. The period 1990-2012 was analysed at maize and potatoes. A shorter period was analysed at sugar beet namely the period 1992-2012. Outline of the possibilities of using phenological data from phenological observations in calculation of soil erosion is the aim of this paper. Phenology can be understood as a tool for detecting changes in the development of vegetation while recent global warming. It was found that phenological data in individual years show great variability. Primarily the influence of vintage has a significant influence on the onset of phenological phases and conducting agricultural operations. The length of growing period of the crop has a major influence on the resulting value of the protective effect of vegetation (C factor). The higher value of the C factor was found at the shorter growing season. The largest percentage difference between short a long growing season was found in sugar beet and to 17.60% (locality Kroměříž). If we are able to reduce the value of one element of the equation through crop management (in this case C factor), then the total erosion value is reduced by a given percentage.
