“…The differences between the higher values of ICP and colorimetric values were not uniform in the determined range of P content in soils. Similarly as in Matula (2010), the difference between phosphorus detection by ICP and that by colorimetry relatively increased as the phosphorus reserve in soils decreased. The difference between (Worsfold et al 2005, Styles and Coxon 2006, Blackwell et al 2009).…”

The simplified acid peroxydisulphate digestion of soil water extract was evaluated for determination of total dissolved phosphorus by molybdenum-blue colorimetry in comparison with direct P-detection in water extract by the ICP-AES technique. The research was conducted on 79 agricultural soils with different agrochemical characteristics. The results of the colorimetric P detection in water extract without digestion and ICP phosphorus detection were different. The median of values determined by ICP-AES was 1.7 times higher than that of colorimetry, but the correlations between the two measurements were quite close (r = 0.993). Differences between the colorimetric phosphorus and ICP-AES phosphorus were irregular, increasing as the phosphorus level in soils decreased. The simplified procedure of acid peroxydisulphate digestion is useful for routine determination of total water-extracted phosphorus in soils when the soil testing laboratory is not equipped with the ICP-AES technique. The two-tailed paired t-test did not prove any difference in the values between the direct ICP-AES P-detection in water extract of soils and colorimetric P-detection in the acid peroxydisulphate digest.

“…Nevertheless, the result of the test is generally reported as phosphorus available for plants. When the supply of 'available' phosphorus in soil is given, it is always necessary to specify the used soil test including the end-point analytical technique of phosphorus determination to avoid a misleading interpretation of the results (Matula, 2010). The need for economic use of phosphorus in agriculture is accentuated by the finite supply of economical P resources (phosphates) for the production of concentrated fertilisers.…”

The pot experiment was established in vegetation hall in the year 2015. Spring barley, variety KWS Irina, was grown. Two different soils -chernozem from Brno (with a low phosphorus content and alkali soil reaction -7.37) and haplic luvisol from Jaroměřice nad Rokytnou (with a high phosphorus content and slightly acid soil reaction -6.01) were used for comparison. The rates of phosphorus in the form of triple superphosphate (45 % P2O5) were increased from 0.3 -0.6 -1.2 g per pot (5 kg of soil -Mitscherlich pots). Nitrogen was applied in the form of CAN (27 % N) at a rate of 1 g N per pot in all the treatments incl. the control. Using statistical analysis, significant differences were found between the two soil types both in terms of the postharvest soil P content and yields of aboveground biomass. The content of post-harvest soil phosphorus increased significantly with the applied rate (96 -141 -210 mg/kg in chernozem and 128 -179 -277 mg/kg in haplic luvisol). Dry matter yields of the aboveground biomass grown on chernozem were the lowest in the control treatment not fertilised with P (38.97 g per pot) and increased significantly with the P rate applied (46.02 -47.28 g per pot), although there were no significant differences among the fertilised treatments. On haplic luvisol phosphorus fertilisation was not seen at all, demonstrating that the weight of the biomass in all the treatments was balanced (48.12 -49.63 g per pot).

“…The use of waste materials may result in aggravation of soil properties and can threat crop production with harmful consequences for end users. Therefore, before using such materials it is necessary to implement the experiments, which may reveal the beneficial and harmful effects of fertilization with waste materials, especially, considering the complexity of the behavior of P in soil (Matula 2010).…”

Irreplaceability of phosphorus as a necessary macroelement in crop production is due to limited resources and costly processing of ores and immobilization in soil, which force for seeking an alternative sources or the use of waste materials. In this paper, the waste aluminum phosphate from pharmaceutical factory used as phosphate fertilizer and its effects were compared with other phosphorus fertilizers (superphosphate and rock phosphate). Except the analysis of available phosphorus (AL-method) the sequential extraction of phosphorus (modified Chang and Jackson) and sequential extraction of aluminum (modified Tessier) were performed. The experimental plant was mustard (Sinapis alba). The pot experiment was carried out on two soil types: Stagnosol and Vertisol. Application of phosphorus with aluminum phosphate had the same effect as the application of other phosphatic fertilizers in both soil types. In Stagnosol Al-phosphate directly influenced the increase in plant fresh weight by 39% and dry weight by 43% compared to the control, and also decreased the content of mobile Al for 40% and Pb for 47% in plant biomass. Based on these results, the use of waste aluminum phosphate has a potential to be used as a phosphorus fertilizer under given conditions.
