Selected Indicators of Sustainability on Organic Farms in the Czech Republic

摘要

The aim of presented work was to figure out values of selected indicators on organic farms in the CR and find out how these values are influenced by farming system. There are some limitations valid for use of fertilisers in organic farming and furthermore some farmers in the Czech Republic themselves apply lower amounts of farmyard fertilisers because of situation on the farm and in the region. Therefore nutrients management is a factor of great importance for maintenance of soil fertility and long term stability and productivity of agrosystem. Other up to date question is energy. It can be supposed that organic farming, as more extensive system, has lower energy inputs but also energy outputs. Important is efficiency of utilisation of this energy for production.
