Conservation agriculture (CA) is an important form of sustainable land management, provided that the three basic principles - no tillage, permanent soil cover, diverse crop rotation or intercropping - are always observed.

Wind or water erosion are common phenomena on the majority of arable land. The resulting soil losses are generally higher than the rate of formation of new soil, so that the depth of fertile soil is decreasing. Moreover, eroded soil can cause severe off-site damages. One way of reducing erosion is the implementation of conservation agriculture (CA); this is a production system in which the soil is no longer ploughed.

According to the Food and Agriculture Organization of the United Nations (FAO), CA is based on three principles:

  • minimum soil disturbance (no tillage),
  • permanent organic soil cover and,
  • a diverse crop rotation or intercropping.

Conservation agriculture has been practised on a large scale for about 30 years.
