The search for the best solutions to restore soil balance is essential for attaining a stable and sustainable agricultural development worldwide. This research, which makes a contribution to these investigations, focuses on four substances (two innovative ones: basalt flour, brown algal extract, and two classic soil improvers: finely ground barley straw and compost) which can potentially alleviate...
Celem badań było określenie wpływu zanieczyszczenia gleby kadmem na aktywność fosfatazy kwaśnej, fosfatazy alkalicznej oraz ureazy. Doświadczenie wykonano w warunkach laboratoryjnych w 3 powtórzeniach. Glinę piaszczystą zanieczyszczono kadmem w postaci wodnego roztworu CdCl2-2,5H2O w ilości odpowiadającej: O, 20, 40 oraz 60 mg Cd2+ kg-1 s.m. gleby. Materiał glebowy inkubowano w temperaturze 25 °C...
W doświadczeniu polowym badano wpływ przedplonu i sposobu zagospodarowania resztek pozbiorowych na aktywność dehydrogenaz glebowych, ureazy, fosfatazy kwaśnej i fosfatazy alkalicznej. Oznaczenia wykonano czterokrotnie w 3 roku trwania doświadczenia. Rośliną doświadczalną była pszenica ozima (odm. Olivin), a przedplonami; rzepak ozimy, rzepak jary i gorczyca biała. Czynnikami zmiennymi obok rodzaju...
W doświadczeniu wazonowym (3 kg gleby w wazonie) określono wpływ zanieczyszczenia gleby (piasek gliniasty) herbicydem Harpun 500 SC na aktywność enzymów glebowych. Harpun 500 SC stosowano w następujących dawkach: 0 - kontrola, 1 - dawka zalecana przez producenta oraz dawki większe od zalecanej: 10, 50, 100, 150 i 200-krotnie. W celu złagodzenia ewentualnego inhibicyjnego wpływu herbicydu na enzymy,...
The effect of soil contamination with copper on soil biochemical properties and oat yields was assessed in a pot experiment. Copper was applied alone or in combination with other heavy metals. The study was conducted on samples of brown soil consisting of heavy loamy sand and brown soil developed from light silty clay. On days 28 and 56 of the experiment the following were determined: activity of...
The effect of soil contamination with CuSO₄ · 5H₂O applied in the following doses of Cu kg⁻¹: 150, 300, 450 and 600 mg on the activity of dehydrogenases, urease and acid phosphatase and alkaline phosphatase was studied in a pot experiment. Two types of soil were examined: heavy loamy sand and silty sandy loam. The experiment was completed in two series: with yellow lupine cultivation and without plant...
The purpose of this study was to use magnesium (50 and 100 mg Mg kg-1) to neutralise possible nega-tive effects of soil contamination with cadmium (10, 20, 30 and 40 mg Cd kg-1) on the enzymatic activity of soil. Soil contamination with cadmium depressed the activity of dehydrogenases, urease, alkaline phospha-tase and, to a smaller extent, acid phosphatase. In addition, cadmium pollution narrowed...
This experiment was performed under laboratory conditions in three replications. Three types of horticultural soil were put in plastic pots using 200 dm(3) per pot. Prior to filling the pots, the soils were carefully mixed with dusty elementary sulfur at 0.0, 1.0, 2.0, 3.0, 4.0 and 5.0 g.dM(-3) and incubated for three months at 18-20 degreesC, maintaining moisture at 60% of capillary water holding...
