The aim of the study was to assess influence Trichoderma spp. and different fertilization levels on flowering nutritional status Begonia × tuberhybrida Voss. ‘Picotee Sunburst’ plants. Before planting, tubers were soaked in water or a mixture spore (T. viride Schumach–Tv14, T. harzianum Rifai–Thr2, hamatum/Bonord/Bainier–Th15) form suspension for 24 h. plants fertilized every 7 days with multi-...

Ethylenediaminetetraacetic acid (EDTA), when used as a main chelator for complex plant microfertilizers, causes many negative environmental effects; therefore, new compounds or use of the known to replace EDTA have been widely studied. In present study, biodegradation rate, (Raphanus sativus) growth stimulation and ecotoxicity towards Daphnia magna Chlorella vulgaris iminodisuccinic (IDS), cons...
