  Our measurements were done in a soil conditioner experiment started in 2014 which was set in conventional tillage system at the Karcag Research Institute where a soil conditioner was used from 2010. Effect of two different soil conditioners on compaction, moisture content of the soil and on CO₂-emission was studied. Measurements were done after sowing of maize and millet, and on stubble after harvesting. It can be established that less degree of compaction was characteristic to the soil of the plots treated for several years with the soil conditioner during the vegetation period than in case of untreated plots. Higher CO₂-emission values were observed on the plots treated for several years than on the control plots. This effect can’t be established in case of soil conditioners used for first time in this year.

  The effect of PRP-SOL soil conditional on soil compaction, moisture content and bulk density is studied in a long-term soil cultivation experiment from 1997 on a heavy textured meadow chernozem soil, in reduced and conventional tillage at Karcag Research Institute. Our investigations were made in the vegetation period of corn, in June and after harvesting, on stubble. Soil compaction was measured with a penetrometer, the actual moisture content was determined by gravimetric method. The bulk density values of the regularly cultivated soil layer of 0–10 and 10–20 cm depths were defined from undisturbed soil samples. We established that after 3 years the application of the soil conditioner has positive effect on soil compaction and moisture status of the top layer in the reduced tillage system. We could not figure out this positive effect in the case of conventional tillage.

  Horticultural activities have been characteristic in the hobby gardens located in the northern and western areas around the town of Karcag for more than 300 years. During the droughty summer periods, characteristic to the region, the water demand of vegetables and fruit trees are covered by irrigation, for that the water is gained from drilled wells. These well waters contain high amount of dissolved salts contributing to the secondary salinization of the soil. Taking these facts into consideration an irrigation experiment was set at the lysimeter station of Karcag Research Institute. Our goal was to mitigate the risk of secondary salinization generated by irrigation with waters of high salt content and to survey the application possibilities of soil preserving irrigation.

  In our study the nutrition reaction of four varieties of winter wheat (KG Bendegúz, KG Kunhalom, KG Kunkapitány, KG Széphalom) has been investigated. In the experiment the effect of twenty different nutrition doses on the yield and thousand kernel weight of the wheat varieties has been studied. Significant difference could be figured out among the yield and thousand kernel weight of the wheat varieties, so the choice of the proper variety determines the quantity of yield. KG Kunkapitány had the highest yield, while KG Széphalom had the highest thousand kernel weight in the experiments.

  Investigating the effect of the nutrients on the yield the conclusion was that all nitrogen doses had significant yield increasing effect compared to the untreated plots, but among the 40, 80 and 120 kg ha^-1 doses there was no statistical difference. In the case of phosphorus the 40 kg ha^-1 dose showed statistically verifiable increase of the yield, while potassium doses have no influence on the yields. The thousand kernel weights reached the maximum values where the highest nutrient doses were applied.

  Irrigation involves the risk of secondary salinization on certain areas. The increase of the level of salty groundwater or the application
  of poor quality (salty) irrigation water can cause secondary salinization. Irrigation from drilled wells is very characteristic in the small
  hobby gardens located around Karcag during the frequently droughty summers. Mainly vegetables and fruits with high water demand are
  grown in these gardens, hence quite a large amount of subsurface waters are used for irrigation. Water samples were taken from 46 drilled
  wells located in the hobby gardens around the town of Karcag and analysed in order to survey the risk of secondary salinization. On the
  base of the results of the analyses and some indexes calculated from the chemical parameters of the irrigation waters, it can be established
  that none of the investigated wells supply water that is suitable for irrigation without improvement.
