Opracowanie optymnlnych dawek i form makro- i mikro elementów pożywki hydroponicznej w metodzie wrocławskiej przy równoczesnym działaniu humianoów [Elaboration of optimal doses and forms of macro- and microelements and hiLrnatcs in the nutrient used in hydroponic culture "Wrocław"]

The effectiveness of macro- and microelements of modified solution of Hampe was investigated. In general, the original doses and forms of ions were optimal. Nevertheless, a pronounced dependence on external factors was found. In aulumn, changes of magnesium doses were of no importance. A double calcium dose was optimal at that time. During summer copper, boron and molybdenum gave better effects if applied in tenfold doses. Applying of humate in non-optimal conditions was distinctly adventageous

Przydatność węgla brunatnego z kopalń Turów i Konin jako ściółki w uprawie hydroponicznej [Utility of brown coal from Turów and Konin mines as the seedbed in hydroponic cultures]

In experiments with 5 vegetables and 5 decorative species – coal from both mines proved to be appropriate as the seedbed. Both types of coal stimulated root growth and maintained iron in soluble form. In general, better and earlier crops were obtained in hydroponic cultures than in pots filled either with soil or with coal watered with nutrient solution
