Conservation tillage (CT) is an effective tool for maintaining crop productivity under adverse climate conditions, while its adoption conditioned by the possible negative response of weed. Research with CT and liming (L) was conducted at different experimental sites on acid soils (ES 1 ES 2) to determine maize weediness yield. The treatments used were ST (conventional tillage), CTD (deep loosen...

Infections of common carp Cyprinus carpio and koi, its coloured morphotypes, with the cyprinid herpesvirus 3 (CyHV-3) can induce severe clinical signs and increased mortality in affected stocks. This may significantly challenge the economic basis of carp farming in Central Europe. To limit virus spread in carp farms, effective disinfection measures for ponds stocked with infected populations ar...

The objective of this work was to evaluate the effect of liming and phosphate applications on the retention of triadimenol in microcolumns of soil material of a distrophic Red-Yellow Latosol (Typic Hapludox) and a distrophic Red Latosol (Typic Hapludox). Lime and phosphate applications decreased retention of triadimenol on LVAd samples (7.7% and 8.6%, respectively, for 2.67 and 10.68 kg ha-1 of...

The aim of this paper is to assess the effect of liming and low doses of municipal sewage sludge (5%, 10%, 15% of the soil mass) on lead, chromium and nickel speciation in soil. The 420-day experiment was carried out in laboratory conditions. In all the samples lead, chromium and nickel concentration was determined with the ICP-AES method, while the content of those metals in different fraction...

To characterise the coatings formed and to analyse element partitioning between the aqueous and solid phase, suspensions were prepared with four grain sizes of limestone and three different amounts of acidic solution from oxidized pyrite tailings. In all cases, red coatings with three different layers covered the grain surface, sealing off the acidic solution. The inner layer was composed mainl...

The contents of this paper are based on experimenThe most important part of the procedure was to tal and practical observations collected over the past establish whether the settling apparatus gave comyears. parable results to the factory or not, and whether there was a correlation. between the. two laboratory settling (1) An Investigation into the of Laboratory tubes. Initially this latter poi...

Phosphorus (P) losses from clay soils can be mitigated by introducing measures for improving soil structure. These include structure liming, where a mixture of CaO or Ca(OH)2 and CaCO3 is added to the soil. In field experiment with separately tile-drained plots on loam in Sweden, we examined effects liming leaching total-P, phosphate P (PO4-P) total nitrogen (N) during three years after initial...
