“…Joanisse et al 2007;Liu et al 2002). The activities of key soil enzymes (such as invertase, protease and urease) are also sensitive to abiotic factors, particularly fertilizer application (Monokrousos et al 2006;Yuan et al 1997;Zakarauskaite et al 2008;Balezentiene and Klimas 2009;Allison 2005).…”

“…One of the basic conditions of producing optimal yields is supplying the plants with indispensable macro-and micronutrients (Zakarauskaitė et al 2008, Skwierawska et al 2012. Unfortunately, recently it was observed that to increase the yields, excessive amounts of nitrogen fertilisers are applied without maintaining the right proportions with the other nutrients.…”

The paper presents the contents of phosphorus and potassium available in soil, soil sorption properties against the activity of alkaline and acid phosphatase. The fertilisation applied involved P, K, Mg, Ca and S: (P K Mg Ca S), (K Mg Ca S), (P Mg Ca S), (P K Ca S), (P K Mg S), (P K Mg Ca) as well as nitrogen fertilisation at the following rates: 0, 50, 100, 150, 200, 250 kg N/ha. The application of high nitrogen rates with no liming applied resulted in an unfavourable increase in hydrolytic acidity and a decrease in the total bases, cation exchange capacity as well as the sorption complex saturation with bases. According to the criteria provided in PN-R-04023, the soil investigated can be classified as the 3 rd class with an average available phosphorus (P E-R ). The analysis of Luvisol salinity demonstrated that the unbalanced mineral fertilisation applied did not trigger any chemical degradation. Significant values of the coefficients of correlation were recorded between the activity of alkaline and acid phosphatase and the parameters investigated (hydrolytic acidity, total exchangeable, base stauration, P E-R ). The calculated enzymatic index of soil pH (AlP/AcP) ranged from 0.11 to 0.72.

“…During the other wheat phenophases, their effect was non-significant, as was the effect of the other types, rates and combinations of mineral fertilizers throughout the growing season. The results of the research conducted over several years by Zakarauskaitė et al (2008) also suggest that low rates of mineral fertilizers have no significant effect on urease activity, whereas application rates above 150 kg/ha significantly reduce the activity of the enzyme in cambisols. Yao et al (2006) and Balezentiene and Klimas (2009) observed that the decline in urease activity during the wheat growing season may be due to lowered mineralization substrate availability and increased soil temperature.…”

“…In this regard, special importance is given to the type, rate and combination of fertilizers as the pillar of effective soil fertility. Zakarauskaitė et al (2008) found that low rates of NPK mineral fertilizers have no significant effect on urease activity, in contrast to high rates, particularly of P and K, which lead to a significant reduction in the activity of the enzyme in cambisols. However, Leinweber et al (2008) reported that low NPK fertilizer rates (60 kg ha -1 ), during the first month after treatment, increase urease activity up to 35 days following application, with their stimulating effect fading away thereafter.…”

SUMMARYResearch was conducted on the effects of mineral fertilizers and manure on urease activity and total nitrogen and ammonium nitrogen contents, and their correlation in a chernozem soil during four developmental stages of wheat.The study involved the following treatments: unfertilized control; N2 (100 kg/ha N); P2 (100 kg/ha P); K2 (100 kg/ha K); N2P2; N2K2; P2K2; N1P1K1 (50:50:50 kg/ha); N2P2K2; N3P3K3 (150:150:150 kg/ha), and N1P1K1 + solid manure (20 t/ha). Urease activity was determined by the method of Hofmann, and total nitrogen and ammonium nitrogen by the Kjeldahl method.The combined application of low NPK fertilizer rates and manure resulted in increased urease activity. All treatments with three-component mineral fertilizers, two-component P2K2 and phosphorus P2 applied during the first two phenophases of wheat inhibited the soil urease activity, whereas at other developmental stages their effect and the effect of other mineral fertilizers on the activity of the enzyme were non-significant. The results indicate differing effects of mineral fertilizers on total N in the soil regardless of developmental stages. Of the single-component fertilizers, the highest total N level was recorded under K treatment. The use of two-component fertilizers produced a higher total N content compared to the single-component ones. Of the NPK treatments, total N content was highest under N2P2K2 treatment throughout the growing season. The N1P1K1 + manure treatment gave the highest amount of total N. Significant differences were found in ammonium N levels between the control and most of the other treatments during the growing season, but no definite pattern could be established.There were no correlations either between the mineral fertilizers used and urease activity or between urease activity and total nitrogen and ammonium nitrogen contents.
