To investigate the effects of different sources of organic matter on soil biochemical properties and crop productivity and to find the best substitute for cow manure in the fields, a field experiment was carried out in a wheat-maize cropping system during 2012-2015. Three types of fertilizer applications, including a mineral fertilizer (CK), straw (S) and biogas slurry (B) were compared with cow manure (M) under an equal dose of nitrogen. In the 0-20 cm soil layer, the soil total nitrogen, microbial biomass nitrogen and carbon content of the M treatment was the highest, and the total organic carbon equivalent ratio of...

Pot experiments were carried out to study the effects of a novel stabilizer of 2,4,6-trimercaptotriazine, trisodium salt, nonahydrate (TMT) on the bioavailability of heavy metals (Cu, Zn, As, Cd and Pb) in soils and heavy metals accumulation in tobacco. The results showed the optimal TMT dosage 200 mL/kg could effectively reduce the bioavailability of heavy metals in soils, and the bioavailability of Cu, Zn, As, Cd and Pb in soils was reduced simultaneously by up to 73.1, 63.2, 48.0, 68.9 and 57.2%, respectively. Application of TMT could significantly decrease Cu, Zn, As, Cd and Pb contents of all parts of tobacco. Furthermore, the contents of available...

In this study, the difference of Se content in brown rice of different rice genotypes was evaluated on natural seleniferous soil. Firstly, the Se content of brown rice in 80 rice germplasm resources was determined, which ranged from 0.0249-0.1426 mg/kg, showing obvious differences. Next, two cultivars with a significant difference in Se content in brown rice, i.e., cv. Wuyangeng (high) and cv. IR68144 (low), were used to study the distribution pattern of Se in different organs. Moreover, the physiological mechanism of the Se content diversity in brown rice of the two cultivars was explored preliminarily. The results showed that the Se content of cv....

The habitus of oilseed rape and its yield component values can be strongly affected by the structure of its stand. Field experiments took place in Central Bohemia in years 2013-2015 aiming at determining the influence of row-spacing (12.5, 25, 35 and 45 cm) on the yield components. Chosen parameters (the number of plants per unit area, the number of pods per plant, the number of seeds per pod and yield) were evaluated at the monitored stands (30 seeds/m2 sowing rate, cv. DK Exquisite). The study confirmed the statistical significance of the influence of row-spacing on some winter oilseed rape yield...

The impact of precipitations and air temperatures on winter wheat yields was evaluated in a 34-year long- term field trial with mineral and organic fertilization established at two experimental sites with different soil-climatic conditions: Ivanovice na Hané with well fertile soils (degraded Chernozem), higher average year temperatures and lower precipitations; Lukavec situated in Bohemian-Moravian highlands with less fertile soils (Cambisol), lower temperatures and higher precipitations. At both sites, a significant positive effect of used fertilizers was noted from the dose of 80 kg N/ha; the best yields were generally obtained at 120 kg N/ha and...

Phosphorus (P) stratification in no-tillage (NT) systems has important implications for crop growth and potential P loss, but little is known about P forms and their distribution when mineral P fertilizers are placed to the depth of 5 cm in NT soil. A 10-year field experiment was used to study the effect of NT and mouldboard plough (MP) on soil P forms at three depths (0-5, 5-10 and 10-20 cm) and their relationship with Fe and Al oxides. The results indicated that stratification of organic P forms occurred under NT treatment, and Fe oxides may have a stronger capacity for adsorbing the P forms. When mineral P fertilizers were placed to the depth of...

The impact of non-treated and primed seeds on molasses components, sugar content and technological white sugar yield of the same cultivar of sugar beet root was investigated. The study was conducted in 2012-2014 at the Experiment Field Station of Warsaw University of Life Sciences - SGGW in Skierniewice (51°97'N, 20°19'E) in the central region of Poland. The use of primed seeds resulted in a higher technological white sugar yield with higher sugar content and lower content of α-amino nitrogen in the roots. Also, seed priming increased the technological value of the roots by a lower share in the root yield fractions of the root weight less than...

This study analyses the effects of expressways on physiology and risk elements content in plants (Quercus cerris L., Prunus spinosa L., Melica uniflora Retz.) and soils. Study forest stands are located at a distance of 30 m to 8100 m from the expressway 'R1 Nitra - Tekovské Nemce' (southwest Slovakia). The effect of distance from the road on the content of cadmium (Cd) in soils indicated an increase of the element in mineral layers in the 30 m variant; excessive Cd values were recorded in O-horizons and in the background zone. Also copper (Cu) showed a marked enrichment of surface horizons caused by car traffic. The results...
