Abstract:
The dynamics of soil phosphorus (P) fractions were investigated, in the rhizosphere of fababean (Vicia faba L.) and maize (Zea mays L.) grown in calcareous and acid soils. Plants were grown in a mini-rhizotron with a thin (3 mm) soil layer, which was in contact with the root-mat, and considered as rhizosphere soil. Hedley sequential fractionation was used to evaluate the relationship between soil pH and P dynamics in the rhizosphere of fababean and maize. Soil pH influenced the dynamics of P fractions in both calcareous and acid soils. Fababean and maize roots decreased rhizosphere pH by 0.4 a

The soils were incubated as suspensions for 14 days at 25�C and the pH and Eh adjusted independently to four levels in the range of pH 4-8-70 and Eh from + 350 to -150 mV. In the prairie and krasnozem soils, the concentration of S in the soil solution at high pH increased as Eh was lowered to +200 mV and then decreased as Eh was lowered further. At low pH, Eh changes did not affect the concentration of S in the soil sol

The study of sulfur (S) forms in the soil is relevant, and its availability depends on pH. The aim was to investigate how pH affects the balance between labile and non-labile sulfur reserves. The randomized block design with four replications was used. The treatments were: 1) soil incubated without pH correction; 2) pH corrected to 6.0 before incubation; 3) pH corrected to 6.0 after incubation. An anionic resin membrane was used to determine labile S. The S extracted in 48 hours was readily labile sulfur (RLS), and that extracted after 48 hours was slowly labile and non-labile sulfur (SLS+NLS)

The application of nitrification inhibitors (NIs) based on ammonium (NH4+) is considered to be an efficient way to reduce nitrogen (N) loss by delaying the nitrification process through influencing ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB). However, the inhibition mechanisms of NIs on AOA and AOB in different soils remain unclear. Hence, we explored the two commonly used NIs (3, 4-dimethylepyrazole phosphate (DMPP) and dicyandiamide (DCD) and their combination (DMPP + DCD) on the soil nitrification and abundance of ammonia oxidizers (AOA and AOB) in three black soils

Human activities have doubled the loading of ecosystems with reactive nitrogen (N) contributing to many serious problems such as eutrophication, climate change and pollution. As most anthropogenic reactive N is created to supply plant-available N in agriculture, one of the ways to mitigate the situation is to improve N use efficiency in crop production. It is also potentially more sustainable to supply N to crops using biological N fixation (BNF) rather than synthetic N fertilisers, because BNF does not rely on energy from fossil fuels to create plant-available N.

Abstract:
Phosphorus, a crucial element for plant growth, is relatively scarce in the Earth’s crust. Its availability in surface soils ranges from 100 to 50 mg/kg. Plants can only absorb phosphorus in the form of orthophosphates, with H2PO4- being most absorbable at low pH levels. The average phosphorus concentration in soil solution is about 0.05 mg/L, but plant-satisfying levels range from 0.003 to 0.3 mg/L, underscoring the need for judicious phosphorus fertilization. Storage and stabilization reactions in soil, mainly facilitated by iron and aluminum oxides, play a key role. Compounds in most soils

The way these factors interact can influence the absorption of micronutrients by plant roots. Once absorbed by the roots, the transport of micronutrients is affected by the way they are complexed and the available concentration in the soil solution.

Abstract:
Dispersions of molybdenum-tungsten blues are promising precursors for the preparation of carbide catalysts by the sol-gel method. Stable systems were synthesized using ascorbic acid as a reducing agent at various molar ratios (Mo) :( W) = 100; 95: 5; 90:10; 80:20; 50:50. To study the properties of colloidal systems, UV / Vis spectroscopy, dynamic light scattering and electrophoretic light scattering were used. It was found that molybdenum-tungsten blue particles with different molar ratios of molybdenum and tungsten have a constant hydrodynamic radius equal to 2.0 nm. In the pH range (0.8 - 3.

Abstract:
This report refers to the activities performed in the frame of PRCI project on the refinement of the dynamic DC stray current corrosion criteria by applying an advanced DC corrosion prediction model. In order to find realistic stray current interference conditions, an industry survey was performed to retrieve dynamic DC interference signals on real-world pipelines. After analysis of the cases, a simulation matrix was proposed that covers a wide variety of interference conditions. The simulated signals were simplified as squared pulses.
