    Weather conditions have an important role in fruit production. In the last few decades, this role is increased and basically determines the
    fruit quality and quantity. Despite of this statement, there is but very few information about impacts caused by weather anomalies in
    Hungarian orchards. Regarding this, the relation between the external, and internal values of the Idared and Golden Reinders apple varieties,
    the changing of the temperature and precipitation in a dry year (2009) as well as in a rainy year (2010) were investigated. The examined
    apple varieties are grown at the same training system (rootstock, spacing, training, pruning system). The average weight, average diameter,
    acid content and soluble solids were higher in 2009 than in 2010, although the precipitation was higher in 2010. Due to the many rainy days
    the intensity of sunshine and the number of sunny days were less. To produce better quality it is very important the amount of the sunshine
    and heat, the optimal temperature and the precipitation rate.

    With the help of this report evaluating the current situation of the region, characteristics of the development in agricultural production and regional differences can be clarified. By mapping out the regional soil, land use and climatic conditions and organizing these into a geographical information system, one can easily determine which plants are the most ideal to cultivate in that particular region. Moreover, it is a useful tool that enables us to
    establish the most favorable land use structure suited to ecological demands and also helps to determine the methods of soil protection.
    During our work, we chose administrative units in Szabolcs-Szatmár-Bereg County, based on the latest aspects of regional cultivation.
    Our pilot areas are: the small regions of Nyíregyháza, Nyírbátor, Nagykálló, Mátészalka and Csenger.
    Using the database, we separated and uncovered the soil conditions of the pilot areas: the chemical and physical properties of the soil layer which is exploited by the roots of the plants, the humus content, the nutrient supply, the thickness of the cultivated layer and the water management conditions.
    We separated the districts of regional cultivation, where the basic elements of the traditional Kreybig color systems were applied (light yellow, dark yellow, light brown, dark green, blue, pink, red, gray, greenish brown, reddish purple, light purple, dark purple, light green).
    By using the data collected from the pilot areas, we compiled a map database, which is suitable to illustrate the plant cultivating characteristics of the region. We made recommendations to determine the most favorable plants to cultivate in the specific region with the given meteorological and soil conditions, as well as for the shifting of crops.
    Our recommendations were also illustrated in a map with a resolution of 1:25000.

    Forests are unique global factors which ensure life for almost every living being on Earth. They play a major role in controlling water flows, preventing erosion and controlling the oxygen content of Earth’s atmosphere. By the end of the XXth century, it was realized that forests help to nature maintain and are vital parts of our natural environment. By the time societies realized this fact, economic and environmental effects had amplified which endanger forests. Due to their good water control and water protection abilities, and their function in climate control, mountain forests can provide a suitable environment for themselves, for their successful growth.
    Forests play a major role in soil protection, especially in mountain areas where they prevent soil erosion. By converting surface waters into subsurface waters, forests help with the accumulation of subsurface waters, which are the sources of springs, rivers and streams. In the summer, they protect the soil from drying out by creating a special microclimate. They positively affect the climate of surrounding territories.

  • The influence of fertilization on the soil characteristics of a calcareous chernozem in a long term experiment

    In the long term fertilization experiment of the University of Debrecen, Centre for Agricultural and Applied Economic Science(CAAEC) (Debrecen Látókép), the effects of a 25-year-long fertilization were examined in terms of some chemical and microbiological properties of soil. With the growing doses of fertilizers, the available nutrient content of soil increased. At the same time the pH significantly decreased, while the hidden acidity increased. Moreover, the ratio between the soil bacteria and microscopic fungi, and the occurrence of microbes also changed. The number of sensitive physiological bacteria groups decreased dramatically. These changes indicate the reactions of living organisms; they correspond to the „resistance stage” of stress effects, but in the case of nitrifying bacteria, they reach the „exhaustion stage”.

    The social care has been accompanying phenomenon of mankind from ancient times. An individual's social and economic processes that affect the lives basically forced the representatives of the powers to help those in need. The concepts used in social care today (equality, solidarity, etc.) have evolved over the centuries, shaped by political ideologies of the content. This wide range of people living in today's society for granted the fact that life is present in the social care system, which is necessary for security.
