  The paper deals with the soil biological research and its contribution to the changed cropping strategy and to the sustainable and environmentally friendly farming and management. The paper emphasizes the importance of biodiversity, as one of the most important ecological functions of soil. The organisms, populations and communities living in the soil play a key importance in the preservation of soil fertility. The most important research areas are presented dealing with in the last decades the national researchers and the challenges we face regarding the current soil biological problems. We have to prepare to examine the soil biological effectiveness of the more widely spread bio-preparations, bacterium preparations, and bioregulators. The prerequisites are the versatile knowledge of the biological state of soils and monitoring examination of the different effects soils had (including the mentioned preparations).

  Nowadays, important task is using more widely the environmentally friendly production technologies. There are considerable differences
  among technologies using reduced spray programs (integrated and organic) in plant protection and plant nutrition.
  In this case integrated production has a better position as roles for organic production more strict and due to this fruits has an obvious
  temporal and permanent reduction in tree conditions. Fitotechnical elements and renewal and regeneration of cultivars are important
  factors for offseting or delaying of condition weakening.
  In this study, 5 apricot cultivars (not pruned for 8 years) were compared in their characteristics (assessment of inactive, semi-active and
  active plant parts).
  Our study showed that there were 50-70% differences among observed characteristics. Our study confirmed those cultivars which are
  suitable for organic production and which one more resistant to condition weakening and which one able to tolerate negative technological
  effects.

  The paper presents a short review of the different types of farming systems:
  Biofarming, Organic farming, Alternatíve farming, Biodynamic farming, Low input sustainable agriculture (LISA)
  Mid-tech farming, Sustainable agriculture, Soil conservation farming, No till farming, Environmentally sound, Environmentally friendly, Diversity farming
  Crop production system, Integrated pest management (IPM), Integrated farming, High-tech farming
  Site specific production (SSP), Site specific technology (SST), Spatial variable technology, Satellite farming.
  Precision farming
  It concludes that the various systems are applicable in different ratios and combinations depending on the natural and economic conditions.
  The author predicts an increase in precision technologies , the first step being the construction of yield maps compared with soil maps and their agronomic analysis. Based on this information, it will be necessary to elaborate the variable technology within the field, especially for plant density, fertilization and weed control.
  The changes in weed flora during the past fifty years based on 10.000 samples within the same fields using the weed cover method are presented.
