Cím:	Elaboration of the methodology of dew measurement by means of weighing lysimeters / Krisztina Czellér, Lúcia Sinka, Géza Tuba, József Zsembeli
Dátum:	2017
Megjegyzések:	Records of the frequency of occurrence of or the total amounts of dew are scarce. The lack of such records can undoubtedly be attributed to the difficulty of making quantitative measurements of dew. Within some limitations large precision weighing lysimeters can be suitable for the accurate determination of dew amounts. The lysimeter data completed with meteorological data provide the possibility to identify such periods with positive water balance when no rainfall occurred hence dew formation is probable. Nevertheless some "data noises" (oscillations) are characteristic to weighing lysimeter data gained with a high frequency for a longer period. These oscillations can be easily mixed up with the weight increase due to dew formation, therefore filtering or smoothing functions must be used to separate them. Our research aimed to elaborate a method that is suitable to separate true dewfall periods from oscillations and to quantify the amount of dew occurred on the surface of 2 weighing lysimeters of Karcag Research Institute of RISF UD for a longer period. The method we applied for filtering was the application of weight data measured with 1 hour frequency instead of 10 minutes frequency. The investigation period lasted from 1/4/2015 to 30/9/2016. Two high precision weighing lysimeters were involved, one with bare soil surface and one with grass cover. 43.11 and 49.35 mm dew was calculated for the grass covered and the bare surface lysimeters for the total 18-month-long investigation period with the application of our method.

Cím:	Correlation of secondary salinization and soil conditioning in vegetable production under irrigation with saline water / Arzu Rivera-Garcia, Géza Tuba, Györgyi Kovács, Lúcia Sinka, József Zsembeli

Megjegyzések:	Secondary salinization is a main problem around the world due to climate change and intrusion of salts in the soil by improper irrigation. Our aim was to study the soil salinization process by simulating vegetable production under irrigation with saline water (total soluble salt content 700 mg L??1). We tested 6 different technologies of soil conditioner application and 3 vegetable crops with different sensitivity to salinity in a small plot experiment set up on a meadow chernozem soil. During the irrigation season in 2020, we regularly measured the electric conductivity (ECa) and the soil moisture content (v/v%) in the topsoil (0.1 m) and analysed these parameters with Pearson's bivariate correlation (PCC) method. As our hypothesis, we expected that there is correlation among ECa, soil moisture content, soil conditioning, and providing the possibility to quantify the secondary salinization process.We found that all the 4 biosynthetic soil conditioners technologies minimized the harmful effect of saline irrigation. In the case of the not salt tolerant (NT) peas, the PCC correlation was higher to compost application and control expressing more intense salinization. NT beans showed a weaker correlation with lower PCCs, which must be due to its higher root activity leading to intensive leaching resulting in a lower degree of salinization. In the case of chilli with low salt tolerance (LT), micro dosing of soil conditioners was not effective in mitigating the harmful effect of secondary salinization, only full doses decreased the PCC. The salt tolerance of the investigated vegetable crops was also manifested in the yields. We found that PCC is a suitable statistical method to understand and quantify the process of secondary salinization.
