The general characteristics of sandy soils are the light mechanical composition, the low content of humus and mineral colloids, large pore size and a bad aggregate stability. They have a poor nutrient supply capacity, due to its high porosity the organic matter is degraded very quickly to mineral colloids (Stefanovits et al., 1999). By the compost application the soil is enriched mineral and organic colloids, thereby improving the soil structure. The effect of addition of compost to soil the water- and nutrient-holding capacity and porosity could be increased and the bulk density could be decreased (Martens and Frankenberger, 1992). The aim of our experiment is to carry out physical measurements to determine the effects of compost treatment. In this study the results of the first year are presented.Tétel Szabadon hozzáférhető The effect of various composts on vegetable green mass on two soil types(2017-05-16) Szűcsné Szolomájer, Judit; Makádi, Marianna; Demeter, Ibolya; Tomócsik, Attila; Aranyos, Tibor; Fehér, Bernadett; Kovács, BélaComposting of sewage sludges makes easier the utilization of sewage sludge in the agriculture and the composts in good quality could increase the nutrient content of soil. Due to the composting process, the sewage sludge composts with high organic matter content can be utilized in the same way as other composts or farmyard manure. Composts produced in different ways have different effects on the physical, chemical and biological properties of different soils, although their positive effects have already proved in the literature. In our study the effects of composts from different composting processes were investigated in soil-plant systems. The different physical and chemical properties of the two examined soil types (arenosol and chernozem)strongly influenced the nutrient supply capacity of composts which could be characterized by the growth of ray-grass as a test plant in the pot experiment. In this work we examined the effects of three different composts on the green weight of plants on the fourth and eighth weeks after the treatment and sowing.Tétel Szabadon hozzáférhető The effect of wet compost extract on the root tubers of green pea(2017-05-16) Fehér, Bernadett; Demeter, Ibolya; Aranyos, Tibor; Tomócsik, Attila; Makádi, MariannNitrogen plays significant role in the life of plants, it could be the main limiting factor of plant growth. Sustainable plant nutrition pays attention to satisfy the plants’ nutrient demand without chemical fertilizers, e.g. by bounding the atmospheric nitrogen. The nitrogen fixing organizations play important role in supplying plants with nitrogenbecause the N2-fixingbacteria can fix high amounts of nitrogen. Many effects of the sewage sludge compost extracts is known in the literature. We studied the effect of sewage sludge compost water extract in laboratory conditions on the growth of Rhizobium spp. isolated from green pea, while in a small plot experiment thepea-Rhizobium symbiosis were studied on sandy soil in the Nyírség region. The extract was produced under aerobic conditions. The compost extract was applied before and/or after sowing. In the laboratory experiments we used the sterile version of extract, in different doses. In our work we present the effect of compost water extract on the number of green pea roots nodules, dry weight of the plant and reproduction of the Rhizobium bacteria.Tétel Szabadon hozzáférhető Field and laboratory evaluation of the long-term effect of various organic fertilizers on sandy soil(2023) Aranyos, Tibor; Zulkipli, Liyana Binti; Makádi, MariannaTétel Korlátozottan hozzáférhető Field and Laboratory Tests for Evaluation of Soil Treatment on Soil Respiration and Its Temperature and MoistureZulkipli, Liyana Binti; Aranyos, Tibor; Kovács, Elza; DE--Mezőgazdaság- Élelmiszertudományi és Környezetgazdálkodási KarThe study determined to discover how living organisms in soil feeds on waste input in exchange of carbon dioxide emission. Soil respiration is a key indicator to the behaviour of soil components and carbon dioxide diffusion from soil to atmosphere. Organic waste is crucial to incorporate into soil to return organic materials to the natural environment and feed microbial communities. Disturbance on soil regulates soil temperature and moisture due to the change in soil structure and aggregation on soil. Soil respiration experiment requires comprehensive understanding of its physiochemical properties and response towards organic input.Tétel Szabadon hozzáférhető Komposzt kezelés hatása homoktalaj fizikai tulajdonságaira(2013) Aranyos, Tibor; Blaskó, Lajos; Tomócsik, Attila; Makádi, MariannaTétel Szabadon hozzáférhető Szennyvíziszap komposzt alkalmazásának hosszú távú hatásai savanyú homoktalajon(2017) Aranyos, Tibor; Tomócsik, Attila; Demeter, Ibolya; Fehér, Bernadett; Makádi, MariannaTétel Szabadon hozzáférhető Toxic elements in the sewage sludge - soil - plant chain(2012) Tomócsik, Attila; Orosz, Viktória; Aranyos, Tibor; Makádi, Marianna; Füleky, György
