Název v původním jazyce

The fluctuation of molybdenum content in oilseed rape plants after application of nitrogen and sulphur fertilizers

Popis výsledku v původním jazyce

The effect of N-S fertilizers on the molybdenum content in oilseed rape plants was investigated in precision field trials. Evaluation was carried out on unfertilized control and two treatments of single fertilizer rates in the first spring fertilizer application, using 100 kg N.ha-1 in AN treatment (nitrochalk) and 100 kg N.ha-1 + 50 kg S.ha-1 in ANS treatment (ammonium nitrate and ammonium sulphate). The results confirmed the significance of sulphur fertilization for the winter oilseed rape plants cultivation technology, even on fertile soils in the Czech Republic. An antagonistic relationship between the sulphate and molybdenum anions in their absorption by plants was demonstrated. Higher and statistically more significant molybdenum levels were determined in the AN treatment. The total above-ground biomass of the plants in the flowering period had accumulated molybdenum at 6.06 g.ha-1 in the ANS treatment, and 8.44 g.ha-1 in the AN treatment.
