Root-released organic acids are reported to increase phosphorus (P) availability in the soil. In this study a dynamic study of P release from soil was conducted to get more exact information of the organic acids role in P availability in soil. The results show that organic acids in different concentrations significantly affected P release. In a concentration of 10 mmol/L, no significant differences can be observed among citric acid, malic acid and acetic acid in terms of their effect on the release of soil P. However, when the concentration reduced to 1 mmol/L, both the total release amount and the maximum release amount of soil P significantly declined,...

In conjunction with soil type and climate, the use of nitrogen fertilizers is a major factor affecting nitrous oxide emissions. This study compares injection of pig slurry and pig slurry digestate at 15 or 20 cm depths with trailing-hose application followed by immediate incorporation. The work was based on a laboratory microcosm experiment with undisturbed soil cylinders (0-30 cm depth) from three arable soils (Histosol, Gleysol and Plaggic Anthrosol). Soil cylinders were fertilized with pig slurry and pig slurry digestate (150 kg N/ha) and emissions of N2O, CH4 and CO2 were monitored. The comparison of application...

Animal manure may be a primary source of cadmium (Cd) to Chinese farmlands because abnormally high values of Cd were observed in various manures. In this study, we evaluated the potential risk of Cd in soil-plant (maize and soybean) system as a result of the long-term (10 years) application of pig manure (PM). During 10 years, the loading rate of Cd through PM application ranged from 26.33-131.50 g/ha/year, while the crops removal rate of Cd was relatively small in comparison to the quantity of Cd supplied by PM application (1.03-4.36 g/ha/year). The PM application significantly increased total Cd concentration in soil. Although the Cd levels did not...

The aim of this study was to elucidate the zearalenone (ZEA) migration in the agricultural environment, from the field (wheat, corn), through soil and ending in water. All samples were collected in the agricultural area of Western Poland in period between March 2010 and December 2012 (three-year study). Determination of ZEA in environmental samples, after extraction and purification, was carried out with use of high-performance liquid chromatography. The toxin content in water samples was between 0.5 and 4.9 ng/L and increases in the late summer and autumn (after harvest). The results clearly indicate that ZEA concentration in surface waters depends...

A sand-culture experiment was carried out to investigate the effects of exogenous K2CO3 on salt resistance of moderate-halophyte Sophora alopecuroides. Thirty-day-old seedlings of S. alopecuroides were treated by two levels of salinity (0 and 200 mmol/L NaCl) in combination with four levels of K2CO3 (0, 5, 10 and 15 mmol/L). Gas exchange, chlorophyll content, K+/Na+ ratio, relative electrical conductivity (REC) and antioxidant enzymes activities were monitored after 15-day treatments. The results showed that adequate K+ application effectively counteracted...

Selenium (Se) is a significant trace element for human and livestock animals because of its physiological functions. Se in plants, especially in the crop plants, is treated as a critical dietary source. The effects of foliar spray together with soil application of Se on Se uptake, distribution in common buckwheat (Fagopyrum esculentum M.) plants were discussed in this study. The results showed that both foliar spray and soil application of Se increased Se uptake in common buckwheat significantly (P < 0.05). The highest Se content was observed in leaves (113.37-690.75 μg/kg), followed by roots (28.98-283.78 μg/kg), grains...

Drivers of soil respiration (Rs) in farmland ecosystem have already been widely studied. However, the relationship between Rs and soil fauna (Fs), hydrothermic factor in the triple intercropping system remains poorly known. An LI-6400 XT portable photosynthesis measurement system equipped with a soil respiratory chamber was adopted in the experimental field. Straw mulching treatment increased soil respiration rate but ridge tillage treatment did not have a consistent effect. A regression analysis of the relationship revealed that exponential equation fitted well the relationship between Rs and soil temperature...
