  Maize production is of primary importance in Hungary, especially considering that its cultivation takes up one of the greatest ratios of land used for agricultural production. As a result, the number of farms where maize is not cultivated for either food production or foraging purposes is insignificant. For this reason, establishing economic production is of decisive importance when it comes to determining the efficiency of farms. Profitable maize production depends on a number of conditions, including the professional suitability of farmers, while some aspects of production are independent from these. Heat-sum calculations form a transition from this aspect, since temperatures ocuring during the growing season cannot be influenced by man. However, the method of calculation and evaluation and thus the tool to improve production is in the hands of the farmer. This scientific paper aims to give a general description of heat-sum calculation methods.

  Since the development of remote sensing nearly 60 years ago, there have been many applications for agriculture. Some have proved effective, while others have not succeeded in assisting farmers with problem solving. Recent advances in the spatial, spectral and temporal resolution of remote sensing as well as potential positive changes in cost and availability of remotely sensed data may make it a profitable tool for more farmers. The target area of my research program is the fields cultivated by Kasz-Coop Ltd. considering that this firm is one of the main agricultural firms in the region and its cultivated fields are quite heterogeneous.

  Hungarian agriculture may be characterized by the industry-like, conventional farming of the past decades. This form of management concentrated exclusively on functions aimed at production. We have to decrease this disproportion, especially when joining to the EU, by reducing the intensive agricultural regions and adjusting to the goals of the 2000-2006 NAEP programmes, forming such an agricultural system which integrates the advantages of both environmental protection and complex agricultural systems based on rational foundations. Nevertheless it’s a rational decision to make the soil information system with an exact spatial informatics background as a foundation of agricultural system, because this promotes easy handling as well the connection to possible subsequent modules.
