Abstract Despite the increasing interest in applying composts as soil amendments worldwide, there is a lack of knowledge on short-term effects compost structural and hydraulic properties. Our goal was to study effect vermicompost-based structure, water retention characteristics, aggregate stability plant use efficiency compared that mineral fertilizers food-waste digestate examine if these are evident within short time after application. We set up pot experiment with spring wheat using sandy...

Biochar is produced from a wide range of organic materials by pyrolysis, specifically for improvement poor quality soils. One the main issues nowadays in studying biochar as soil amendment to upscale experiments and move short-term, laboratory conditions long-term field trials. This paper presents study, being final step scale-up technology development, on grain husk fibre sludge application with focus two degraded types temperate region. The effects an acidic calcareous sandy agricultural...

Nitrogen (N) fertilisers should be utilised as efficiently possible. In addition to N fertiliser doses, nitrogen use efficiency (NUE) is influenced by other factors. The effects of four different N, phosphorus (P), and potassium (K) supply levels (0–3) rainfall periods (dry, normal, wet) were investigated on NUE indices in six selected years a field experiment. Generally, had the strongest effects. × interaction increased biomass production from 0.915 t ha−1 (N0, dry) 10.4 (N3, wet). balance...

Abstract Main conclusion Quantitative and qualitative selenium speciation analyses of the root white cabbage reveal presence elemental Se, selenate, selenomethionine deaminated derivatives selenohomolanthionine. White ( Brassica oleracea convar. capitata var. alba ) is one most consumed vegetable brassicas species whose production compatible with recent strip-till no-till type farming policies. has been in focus research for decades as a possible source food-derived supplementation; however,...

Increasing the fertility of sandy soils is a worldwide problem. A field experiment investigated combination two increasing methods, application biochar (BC) and plant growth-promoting rhizobacteria inoculum in acidic calcareous from temperate region. The treatments studied were BC alone; with inoculum; on carrier; conventional carrier at four dose levels. levels 3, 15 30 t/ha. As test maize was sown. Based chemical biological changes observed soil, more decisive factor treatments. increased...

Achieving a sustainable increase in the fertility of sandy soils is major problem. The application biochar (BC) relatively new method, but results for temperate climate are scarce. This work investigates various combined doses BC and plant growth-promoting rhizobacteria inoculants on acidic calcareous soils, hypothesising that joint could have synergistic impact. effects were followed by measuring chemical (pH, organic matter, nutrient availability) microbiological properties soil maize...

Determining the maturity of compost and other organic fertilizers is very important because possible phytotoxic or phytostimulative effects. The can be assessed on basis chemical analyses, germination test with different plants most often used to determine phytotoxicity. In this research, using results produced from plant residues after maintenance green public areas was assessed. At same time, a carried out 4 species (cucumber, garden cress, triticale, barley) phytotoxicity (i.e. extract in...

A soil column experiment was set up to investigate the effect of red mud from Ajka (Hungary) on a typical profile affected area. The chemical changes caused by leachate and effects these living organisms were assessed. Ecotoxicological tests performed with Vibrio fischeri, Sinapis alba Folsomia candida number aerobic heterotrophic microorganisms determined. total, plant-available, exchangeable water-soluble fractions Na, Mo, Cu Cr increased in soil, mostly owing their leaching layer, but...

Iodine uptake and translocation was studied in cabbage tomato cultivated on different soil types (sand, sandy silt, silt) by applying irrigation water containing iodine at concentrations of 0.1 0.5 mg/L. treatment the applied did not significantly influence photosynthetic efficiency chlorophyll concentration leaves. The growth leaves sand silt with slightly stimulated, while, soil, it remained unchanged; for plant parts, independent soil-type, dry mass values constant. It can be concluded...

Accumulation of iodine by potato ( Solanum tuberosum L.) and carrot Daucus carota L. var. sativus ) plants cultivated on different soils (sand, sandy silt, silt) using irrigation water containing at concentrations 0.1 0.5 mg/L was investigated. In the edible organs control grown sand, silt soils, were 0.15, 0.17, 0.20 mg/kg (potato) 0.012, 0.013 (carrot); after treatment applying dosage, 0.21, 0.19, 0.27 3.5, 3.7, 3.0 (carrot), respectively. Although had no significant effect biomass...

Stabilization capacity of 5% by weight lignite added in three particle size ranges (<0.5; 0.5–1.0 and 1.0–2.0 mm) to acidic (pH = 5.0) or calcareous 7.7) sandy soil samples <2 mm grain artificially contaminated with 375 mg/kg Cr(III) was assessed through fit-for-purpose leaching tests performed CH3COOH, NH2OH·HCl EDTA. About 90% 60% were immobilized soils per se, respectively. Although the point zero charge measurements (pHpZC≈4.5) indicated that could effectively bind positively charged Cr...

When making management decisions regarding the conditions of Great Hungarian Plain, it is important to consider soil clay content and salinity. Because moisture vary from extremely dry wet throughout year, this limits use electric methods. In study, we looked for fast, independent techniques estimate Gamma dosimetry X-ray fluorescence spectroscopy (XRF) were tested showed consistent values. two contrasting transects: one passing top dune valley (Sanddune-Valley), another an elevated...

Vermicomposts and composts prepared from sewage sludge digestate additives (spent mushroom compost, straw, biochar) after 43 days pre-composting followed by 90 vermicomposting with Eisenia fetida or compost maturing were investigated regarding the potentially toxic element (PTE) As, Co, Cr, Cu, Mo, Ni, Pb Zn contents. The average increment in total PTE concentration for entire process was ten times higher (104 %) compared to solely composting (9.3 9.5 %, respectively) pretreatment. Compared...

Phytoremediation is an approach designed to extract excessive heavy metals from contaminated soils through plant uptake. Cadmium (Cd) among the elements most toxic living organisms. Health hazards associated with lethal intake of Cd include renal (kidney) damage, anaemia, hypertension and liver damage. A greenhouse experiment was carried out Indian mustard ( Brassica juncea ) grown on artificially spiked soil (100 μg g −1 EDTA (2 mmol kg in 5 split doses), FYM, vermicompost (VC) microbial...

Abstract A uniform multivariable model system was used to investigate whether lignite from Visonta (Hungary) has a stabilizing effect on the heavy metals Cr, Pb, and Zn in case of complex soil contamination with these metals. The investigated acidic sand. Soluble element concentrations extracted by distilled water, ammonium acetate buffer, ammonium-acetate + EDTA extractant were determined. humus quality its influence cation exchange capacity also measured. results evaluated using analysis...
