“…However, when the fertiliser dose was increased even more, it did not have a statistically significant effect on the activity of this enzyme. Yang et al (2008), Zhao et al (2009) and Symanowicz et al (2014) also observed that mineral fertilisation significantly influenced variation in the urease activity. In our study the soil sampling term did not have significant effect on the urease activity in either of the crop rotation systems.…”

“…Enzymes present in soil can be used as bioindicators of the quality of the soil environment [Symanowicz et al 2018, Adetunji et al 2017. Each type of soil is characterized by a specific level of enzymatic activity [Piotrowska-Długosz et al 2021], that is influenced by the type of mineral, natural and organic fertilization [Chu et al 2007, Symanowicz et al 2014, Szymanowicz et al 2018]. In addition to the type of fertilization, its dose is also important [Natywa et al 2014].…”

The aim of the study was to determine the influence of habitat, cultivar and developmental growth stage on catalase activity in soil under two amaranth cultivars – Rawa (Amaranthus cruentus L.) and Aztek (Amaranthus hypochondriacus × Amaranthus hybridus L.). In a 3-year field experiment (2013–2015), amaranth’s plants were grown in a wide-row spacing on the soil of the good wheat complex in south-eastern Poland (50°71'N, 23°04'E). The field experiment included 4 variable factors: weather conditions; selected amaranth growth stages (5-leaf, full flowering and seed maturity stages); NPK dose combinations (I: 40 kg N ∙ ha–1, 30 kg P ∙ ha–1, 30 kg K ∙ ha–1; II: 60 kg N ∙ ha–1, 40 kg P ∙ ha–1, 40 kg K ∙ ha–1; III: 80 kg N ∙ ha–1, 50 kg P ∙ ha–1, 50 kg K ∙ ha–1; IV: 120 kg N ∙ ha–1, 70 kg P ∙ ha–1, 70 kg K ∙ ha–1) and two cultivars (‘Rawa’ and ‘Aztek’). No pesticides are applied in the cultivation due to the absence of pathogens and pests of this plant in Poland. Plant protection was limited to reducing weed infestation twice. The conducted research showed that weather conditions were the main factor affecting catalase activity in the soil under amaranth cultivation, followed by other factors, such as fertilization, cultivar and growth stage. All the analyzed factors proved to exert a significant impact on organic matter content in the soil, while only the applied NPK fertilization had effect on sorption capacity. Moreover, it was found that the cv. Aztek positively influenced the activity of catalase and humus accumulation in the soil in comparison to the cv. Rawa. The beneficial effect of amaranth on the soil environment and its enzymatic activity was ascribed to the lack of introduced pesticides.

This study examined changes in soil enzymatic activity caused by constant mineral fertilization with NPK and diversified fertilization with Fe and Mo micronutrients. A field experiment was conducted in a completely randomized design with four replications in Siedlce (central-eastern Poland) between 2012 and 2014. Alfalfa (Medicago sativa L.) was used as the test plant. The first factor consisted of fertilization treatments: control; NPK; NPKFe1; NPKMo1; NPKFe1Mo1; NPKFe2; NPKMo2, and NPKFe2Mo2. The second factor was composed of the time of soil sampling (15 August 2012, 20 September 2012, 17 June 2013, and 20 July 2014). Mineral fertilization was applied: N-20; P-22; K-124.5; Fe1-0.5; Mo1-0.5; Fe2-1.0; Mo2-1.0 kg ha−1. Application of molybdenum (Mo2-1.0 kg ha−1) in alfalfa fertilized with NPK was optimal for obtaining the beneficial nitrogenase activity. The applied NPKFe1Mo1 fertilization in alfalfa cultivation was optimized to achieve high dehydrogenases activity, alkaline phosphatase activity, and acid phosphatase activity. The highest of soil urease activity was determined in soil fertilized with NPKFe2Mo2. The biochemical index (BCHI) of soil fertility reached its highest mean value (254.9) after applying the NPKFe1Mo1. A high BCHI soil fertility index indicates the possibility of generating high alfalfa yields and maintaining good soil culture.
