    uptaking macroelements by spring triticale
    Opis:
    Taking into consideration the acid pH soil, high content of potassium in relation to nitrogen and phosphorus and the insignificant quantity of heavy metals in the potato pulp and the slight alkaline pH soil as well, high amount of nitrogen and phosphorus in relation to potassium in the municipal sewage sludge, the experiment was carried out in order to define the effect of composts from these waste on uptaking macroelements by the grain and the straw of the Wanad variety spring triticale. The vegetative - pot experiment was carried out on the brown incomplete soil of the slight acid pH (pH(KCl) 6,1), of the granulometric composition of slight loam (V complex), an average content of available forms of phosphorus and potassium and a high content of magnesium. The obtained results show that the grain and the straw of spring trticale took distinctly more macroelements under the influence the fertilization of the composts with the municipal sewage sludge (30%) and the potato pulp (30%) in comparison with the composts with the 60% participation of the potato pulp. The supplementary mineral fertilization which was used against in comparison to composts, increased uptaking the macroelements by the tested plant. The double dose of composts and mineral fertilizers visibly increased nitrogen, phosphorus, potassium, cooper, magnesium and sulphur absorbance by the grain and the straw of spring trticale in comparison with the series with a single dose of composts and a supplementary mineral fertilization.

    Opis:
    The pot experiment was set up under the conditions of the hall of vegetation in 2002. The municipal sewage sludge and composts produced with the GWDA method in 2001 based on municipal sewage sludge with the 30% addition of structuring materials, in conversion to the dry matter, were used in the experiment. The pot experiment was set up with the split-split-plot method in three repetitions. The objects of the first factor were the doses of sewage sludge and composts (1 dose = 13 g , 2 dose = 26 g, 3 dose = 39 g, 4 dose = 52 g of dry matter in relation to the soil weight in the pot), the objects of the second factor were the types of organic fertilization (sewage sludge, 0,5-year compost prepared from sewage sludge, 1,5-year compost prepared from sewage sludge), objects of the third factor were the variants with and without nitrogen and potassium fertilization in the rates of 0.27 g N and 0.26 g K per pot. The experiment was conducted in Kick-Brauckmann's pots of 9 dm3 capacity in which 8 kg of soil were placed. The test plant cultivated in the experiment was Miscanthus sachariflorus. Seedlings of Miscanthus were planted in the first year of the experiment. The obtained results show that the content of macronutrients: nitrogen, phosphorus, potassium in straw of Miscanthus sachariflorus was not dependent on the type of organic fertilizers used in the experiment. However, supplemental nitrogen-potassium fertilization significantly increases the content of potassium in the test plant in all three years of research and nitrogen in the second year. The conducted research shows that the uptake of macronutrients depended on the dry matter yield quantity and the content of a given element in the yield. Within three years the straw of Miscanthus sacchariflorus took up the most of potassium - 11.63 g from the pot and the least of magnesium 1.20 g from the pot. The amount of the absorption of nitrogen, phosphorus and magnesium by the biomass of Miscanthus sacchariflorus from the pot on the objects fertilized with organic fertilizers was the highest in the second year of the research, which was a result of mineralization of the applied fertilizers.
