Megjegyzések:Over the last few decades, the rate of soil acidification has been increased by intensive land use in most agricultural production systems. The objective of this study was to identify in which extent the acidification of a calcareous chernozem soil could be affected by fertilisation, irrigation, and tillage. This study was conducted in 2007 at the Látókép Experiment Site of the Centre for Agricultural and Applied Economic Sciences, Debrecen University located in the north-eastern part of the Great Hungarian Plain. The examinations were carried out under irrigated and non-irrigated conditions, in the 0, 120 and 240 kg N ha-1 plots, respectively. The investigated tillage treatments were winter ploughing (WP) to a depth of 27 cm, spring ploughing (SP) to a depth of 22 cm and disk tillage (DT) to a depth of 12 cm. Soil pH measurements were made using portable Sentron Argus pH Meter equipped with Sentron Hot-line LanceFET probe to a depth of 0-10 cm. Soil acidification was significantly affected by all investigated factors. Typically low soil pH was measured in the DT treatment with 240 kg N ha-1 under irrigated conditions. Based on the results of this study, the applied high dose of nitrogenous fertiliser with inappropriate tillage practice could accelerate the acidification of soils to a great extent under irrigated conditions. Land users have to support the regeneration of soil conditions by regularly applying lime to counter the acidification processes.

Cím:Modelling the soil-plant water cycle in maize production : a case study for simulation of different sowing dates on chernozem soil / Huzsvai László, Megyes Attila, Rátonyi Tamás, Bakó Károly, Ferencsik Sándor
Dátum:2012
ISSN:0546-8191
Megjegyzések:The more and more extreme distribution of rainfall enforces the development of the most accurate water management and soil moisture detecting possible. Monitoring and modelling are two possible solutions. The aim of our examinations was to simulate the effect of different sowing dates of maize on the soil-plant water cycle on chernozem soil in the 2009 growing season. The modelling was performed by the AGROAQUA irrigation decision support system. This study was conducted at the Látókép Experimental Station of the Centre for Agricultural and Applied Economic Sciences, Debrecen University (47?30' N, 21?36' E, 111 m asl). The investigated sowing date treatments were early sowing (ES) at 5th April, optimum sowing (OS) at 20th April and late sowing (LS) at 14th May. In the OS treatment, the soil was dried out to the wilting point at the sowing depth; water deficit was 13 mm from emergence to the end of May. From the intensive grain filling period (18th July) severe water deficiency (60?75 mm) was observed. In ES, compared to the OS treatment, water deficit was eliminated at emergence. Significant water deficit (75?90 mm) was developed after 15th July, during the grain filling phase only. At delayed sowing the water shortage of the sowing depth was significantly higher at emergence than in the ES and OS treatments. A more moderate water deficiency was simulated at silking and in the grain filling period, since the potential evapotranspiration (PET) decreased at this time.
