  Tulip can be grown in parks as ornamental plant and cut flowers, or possibly in protected areas for cut flowers during winter and early
  spring.
  An important condition for the successful cultivation of tulips is the quality of the bulbs that are going to be planted and their
  biological preparation.
  Under the quality aspect bulbs have to be uniform and large, preferably with circumference greater than 11 cm and must have good
  phytosanitarical status.
  Preparation of organic bulbs for ensuring the continuation of the differentiation process of germs (floral), is made during the storage.
  It is known that the preparation of organic bulbs are made in interaction with environmental factors, among which temperature plays an
  important role. At the beginning and throughout the process of biological preparation, temperature is maintained at a higher level then the
  temperature must be low until planting.
  The temperature level and the duration of treatment varies by followed objective respectively early or late flowering and staggered
  flowers production over a longer period of time.

  After evaluating the sample sites’ soils and environmental status, we built up 2 different soil information systems. The first relies on analog data (soil maps), and is based on a regional model; its sample site is the Bihar sub-region. The second is a complex, field scale virtual 3D system, based on several types of data sources. (Aerial photos, GPS, field samples, hyper and multispectral images, soil maps). In this paper, we analyze and evaluate these systems. The greatest advantage of the models is that, with their usage, we can reveal connections which cannot be made by analyzing the individual elements of our data sources. We discovered that with the help of our systems, the monitoring and evaluating of the processes taking place in the soil is more fast and simple.
