Nutrition status of greenhouse tomato grown in intert media. Part I. Macroelements by Piotr Chohura, Andrzej Komosa

“…Two feeding solutions were used: I, containing (in mg dm-3): N-NO3 – 189, P – 62, K – 371, Ca – 190, Mg – 49, Fe – 0.84, Mn – 1.87, B – 0.32, Zn – 2.01, Cu – 0.048, Mo – 0.048, pH 5.5, EC – 3.2 mS cm-1; and solution II with the concentration increased by 20%, and three inert media: rockwool (Grodan), polyurethane foam (Inert) and expanded clay (granulation 4–8 mm). …”

DIFFERENTIATION OF MICROELEMENTS CONTENTS IN NUTRIENT SOLUTION AND DRAINAGE WATER IN GROWING OF ANTHURIUM (Anthurium cultorum Birdsey) IN EXPANDED CLAY by Tomasz Kleiber, Andrzej Komosa

“…Plants were grown in expanded clay with the use of drop fertigation with standard nutrient for anthurium in inert substrates (in mg·dm-3): N-NH4 < 14.0, N-NO3 105.0, P 31.0, K 176.0, Ca 60.0, Mg 24.0, S-S04 48.0, Fe 0.840, Mn 0.160, Zn 0.200, B 0.220, Cu 0.032, Mo 0.048, pH 5.5–5.7, EC 1.5 – 1,8 mS·cm-1. Subject of studies was the differentiation of microelement content in drainage waters driped from the substrate in relation to the supplied nutrient. …”

DIFFERENTIATION OF MACROELEMENT CONTENTS IN NUTRIENT SOLUTION AND DRAINAGE WATER IN GROWING OF ANTHURIUM (Anthurium cultorum Birdsey) IN EXPANDED CLAY by Tomasz Kleiber, Andrzej Komosa

“…Plants were grown in expanded clay with the application of fertigation with a standard nutrient solution (in mg·dm-3): N-NH4<14.0, N-NO3 105.0, P 31.0, K 176.0, Ca 60.0, Mg 24.0, S-SO4 48.0, Fe 0.840, Mn 0.160, Zn 0.200, B 0.220, Cu 0.032, Mo 0.048, pH 5.5 – 5.7, EC 1.5 – 1.8 mS·cm-1. Significant changes of macroelement contents were found in drainage water in comparison to nutrient solution. …”
