The influence of long-term regular mineral fertilization on the soil environment considering the total sulphur and the sulphur balance in the habitat of the permanent mountain meadow was investigated. The experimental field (set up in 1968) is situated at Czarny Potok (20°8' E, 49°4' N) in the central part of the Polish Carpathian. With completed annual NPK fertilisation 1.8 kg S/ha was introduced into the soil. The highest sulphur amount was found in the 0-10 cm horizon and this value slightly exceeded the content considered as natural. The sulphur content in the sward from Czarny Potok was lower than the mean sulphur content calculated in Poland...

Partial characterization of iron binding compounds in spinach above ground biomass and differences between binding of Cd, Zn and Fe in spinach biomass were investigated on two soils treated by sewage sludge in model pot experiment. After application of sludge to both soils, Cd and Zn accumulation in spinach biomass was increased in sludge treatments. Total Fe content in biomass showed opposite trend with these treatments and was decreased 2.5-2.7 fold. Results of sequential analysis of spinach biomass showed lower portions of iron in all individual fractions of both sewage sludge treatments compared to control treatments. The largest differences in...

The laboratory incubation with glucose treatment was carried out in order to estimate the possible effects of increased microbial activity on heavy metal availability. The soils from vicinity of a lead smelter operating for more than 200 years were used for the experiment. The DTPA-extractable heavy metal contents increased after glucose addition and mostly reached the highest values the second day of the incubation. The comparative study, where the chloroform fumigation was used prior to the incubation in order to decrease the microbial activities, showed especially from second day of incubation significantly lower DTPA-extractable metal contents...

Vicine and convicine were isolated from mature seeds of Vicia faba L. These compounds were separated from the relevant fractions by HPLC and identified by IR, MS and NMR. Obtained vicine was used for all bioassays. Vicine in concentration of 25 µg in 1 ml of medium had significant toxic effect. The concentration of 5 µg of vicine in 1 ml of medium had significant fungistatic effect for fungi Fusarium culmorum and Alternaria alternata. The concentration of 500 ng of vicine in 1 ml of medium had significant fungistatic effect for fungi Cladosporium herbarum and Botrytis cinerea. The effective...

The effect of addition of treated sewage sludge on the accumulation of Zn in plants was tested in pot experiment. The additions of eight months preincubated sewage sludge at temperature of 20°C under aerobic and anaerobic conditions with addition of peat and straw were tested. Two different combinations were designed: first consisted of 50% sludge + 35% peat and 15% straw, and second was made of 50% sludge + 5% peat and 45% straw (expressed as dry matter). Three different soils Chernozems, Luvisols, and Fluvisols and three sludges were tested in the experiment. Oat (cv. Pan) was planted as experimental crop. All treatments were fertilized by NPK. Green...
Aluminium induced acid phosphatase activity in roots of Al-sensitive and Al-tolerant barley varieties

Plant Soil Environ., 2002, 48(12):556-559 | DOI: 10.17221/4412-PSE
In barley roots significant increase of acid phosphatase activity was observed during Al treatment. Especially steep increase was found in the roots of Al-sensitive cv. Alfor treated with Al in the range of 1-10mM which was followed by sudden decline when higher concentration (10-100mM) was applied. Continual, but significantly lower increase in phosphatase activity was also demonstrated in the roots of Al-tolerant cv. Bavaria in the range of 1-50mM Al. In both cases, Al-induced increase of acid phosphatase activity was accompanied by the increase in the amount of one phosphatase isoforme. Contrary to cv. Alfor where Al-induced changes reached their...
