  The role of retaining population in agriculture is stronger and more significant in the long run in the North Great Plain Region compared to other regions. The region has a significant processing industry along with a good basis for producing raw materials, developed food processing capicity and high quality agricultural products typical of the region. The GDP in agriculture, forestry and game management is somewhat higher than the national average.
  Variety is of cardinal importance when establishing the quality of horticultural products and determining the product value. The Hungarian breeding results of apple, quince, apricot, cherry, raspberry, red and black currant are promising.
  The regulation system of EU the vegetable and fruit market is based on Retail Cooperatives Producers. With the establishment of national vegetable- and fruit production and retail organizations, the market regulation, production and quality development issues of the sector can be handled and solved. Reaching EU standards in fruit production can only be achieved with up-to-date plantation systems and breed selection. A key issue in development is establishing the required financial resources for investments and updating production. In order to reach these standards, significant state subsidies and good credit conditions are needed. By solving these tasks, the sector is expected to become self-financed without government help.
  The pursuit of safer production, improving quality and increasing yields require the establishment of up-to-date irrigation systems. The improvement of family farms, motivating land concentration is necessary for increasing average size of plants. Establishing the above mentioned conditions is important since the vegetable-fruit sector is of great significance in the employment of rurally based population, improving their living conditions and executing rural development programs.

  During my research, I studied the 0.01 M CaCl₂ extractable NO₃^--N, NH₄⁺-N, Norg, P and K contents of the soil samples originated from a long term fertilisation trial in the experimental site Hajdúböszörmény. Relationships among the soil nutrient contents, the agronomic nutrient balances of the 2009 year, and fertilization were studied. 
  From the results of the study it was concluded as follows:
  – Fertilization significantly increased the CaCl₂ extractable NO₃^--N, NH₄⁺-N, and K contents of soil.
  – Norg fraction increased as a function of the increasing yield. Hence, it can be assumed that the greater the produced yield, the more the stubble and root residues remain on the arable land. These organic residues can result significant increase in the Norg content of soils.
  – The CaCl₂ extractable P and K contents were compared with the calculated P and K limit values. According to these, the experimental soil has a good phosphorus and lower potassium supply capacity. These results are in accordance with the results of the conventional Hungarian fertilization recommendation system.
  – It can be stated that the 0.01 M CaCl₂ is able to determine not just inorganic N forms but Norg fraction as well that characterize the easily mineralizable nitrogen reserves. The results proved that AL-P and -K (ammonium lactate acetic acid, traditional Hungarian extractant) are in good agreement with the P and K reserves, but it is important from the aspect of environmental protection and plant nutrition to measure the easily soluble and exchangeable K-, and P-contents of soil. 0.01 M CaCl₂ method is recommended for this.
