Cím:	Advanced evaluation of spatial inhomogenity of light sandy soil / Tamás János, Nagy Attila
Dátum:	2009
Megjegyzések:	The aims of our study was to survey the spatial distribution of physical and water management properties of soils in order to evaluate the effect of high precipitation intensity on orchards and to supply complex research evaluation activities for further studies. The main goal is to establish such a precision decision support system, with which the water management properties of soil can be meliorated, and can be reduced the effect of high precipitation intensity on orchards. The examinations were carried out at an intensive apple orchard in Debrecen-Pallag. The examination site is the part of the Experimental Pomology Site and Study-Farm of the University of Debrecen, Centre of Agricultural Sciences and Engineering, Faculty of Agronomy. Grain-size distribution, upper limit of plasticity according to Arany, element content by X-Ray fluorescence spectrometry, maximum and minimum waterholding capacity, water capacity of gravity pores, soil density acidity, electric conductivity of soils were measured to obtain appropriate information on the physical and water management properties of the soil. Based on the results, the accurate spatial positions of those sites were characterized where soil loosening should be implemented in 30-40 cm depth. Spatially precise soil physical barriers were determined for micro-irrigation system. Based on the micro-element content and pH, the accurate spatial positions of those sites were selected where melioration and micro-nutrient fertilization is needed.
