Effect of soil moisture regulation method in young peach orchard on selected physical properties of soil

The experiment was set founded in 2012 in the Research Station in Samotwór belonging to the University of Life Sciences in Wrocław. The soil moisture in the peach orchard was controlled by the using of drip irrigation and geocomposite placed in the soil. The impact of these factors on the formation of some physical properties of soil was estimated in the 2 nd year of cultivation. It was the 1st year of the peach trees yielding. The soil under irrigation had the higher bulk density in the surface layer and lower values of porosity. The use of polymer gel alone and with irrigation reduced the soil bulk density in the soil layer at 15-20 cm of depth. The soil under polymer and irrigation was characterized by the lowest value of the capillary porosity. Introduction geocomposite into the soil at the time of planting trees can improve the ability of the soil to retain water in the soil and its efficient management throughout the growing season of trees ...

INFLUENCE OF GEOCOMPOSITE APPLICATION ON SELECTED BIOMETRIC FEATURES OF ROSA 'WHITE MEIDILAND' AND BERBERIS THUNBERGII 'GREEN CARPET' IN THE CONTAINER NURSERY PRODUCTION

An innovative technology of superabsorbent application in a form of agrotextile filled with polymer, called geocomposite, is a solution that allows preserving the beneficial effect of using superabsorbents with simultaneous reduction of their negative influence on soil environment. Research was carried out in 2012-2014 on one year old cuttings of Rosa 'White Meidiland' and Berberis thunbergii 'Green Carpet' in unheated foil tunnel at the Research Station belonging to the Department of Horticulture at Wrocław University of Environmental and Life Sciences. First factor was the use of geocomposite, while the second was fertilization with full (3 g) and half (1.5 g) dose of Osmocote Plus 3-4M and 3 g of YaraMila Complex fertilizer. The aim of this study was to assess the influence of geocomposite application with the use of fertilizers on selected biometric features and fresh weight of plants. Geocomposite had the positive influence on tested shoots and roots biometric features of Rosa ‘White Meidiland' and Berberis thunbergii 'Green Carpet', on the fresh weight of roots and total of both species, as well as on their root:shoot ratio. In both species there was a tendency to obtain the highest values with 1.5 g Osmocote fertilization. ...
