The main objective of the study was to determine the nutritional status in terms of the content of microelements, such as iron, manganese, zinc, copper and boron in several standard cultivars of anthurium (Anthurium cultorum Birdsey) called Baron, Choco, Midori, Pistache, President and Tropical. The plants were grown in expanded clay (ř 8-18 mm) using drip fertigation with standard nutrient for anthurium...
The experiment was established in the spring of 1999 on grey brown podsolic soil formed from boulder clay. Apple trees of cv. Golden Delicious were planted on rootstock at 3.5×1.2 m (2381 trees⋅ha-1). The first factor in the experiment consisted of the levels of potassium in the arable soil layer: 120, 160 and 200 mg K⋅kg-1 of soil d.m., on the basis of annual chemical analyses and determined by universal...
Vegetation studies were conducted from 2002 to 2004, in two leading farms, located near Poznan where have obtained optimum anthurium (Anthurium cultorum Birdsey) yielding. 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...
