Environmentally-benign plant protection possibilities against domestic Monilinia spp. in organic apple and stone fruit orchards
101-105Views:519In this study, possibilities of environmental-friendly plant protection against domestical brwon rot species were summarized for oecological pome and stone fruit orchards. Symtomps of the two most important brown rot species (Monilinia fructigena (Aderh. & Ruhl.) Honey and Monilinia laxa (Aderh. & Ruhl.) Honey) were described and then cultivar susceptibility to brown rot was discussed. Furthermore, mechanical, agrotecnical, biological, and other control possibilities (stone powders, plant extracts and restricted chemical materials) were shown.

Optimized balance between crop productivity, restoration and maintenance of vital soil functions and soil carbon sequestration and storage – the SmartSOIL (FP7) project
213-215Views:246Soils provide the most indispensable function of supporting the production of food and feed for a growing human population. At the same time they provide a range of regulating and supporting functions related to climate change and removal of greenhouse gases. The majority of the soil functions are closely linked to the flows and stocks of soil organic carbon (SOC); low levels of both flows and stocks may seriously interfere with several of the essential soil functions and thus affect the ecosystem services that soils deliver. Soil degradation is considered a serious problem in Europe and a large part of the degradation is caused by intensive cultivation practices in agriculture. The aim of the SmartSOIL project is to link the results of different scientific fields through a holistic and multidisciplinary approach and as a result develop a decision making tool contributing to sustainable development.

Comparative examination of a bacterium preparation (BACTOFIL® A10) and an artificial fertilizer [CA(NO3)2] on calcareous chernozem soil
75-80Views:365In a small-pot experiment a bacterium preparation, Bactofil® A10 and an artificial fertilizer containing Ca(NO3)2 in different dosages were studied on calcareous chernozem soil, concerning the readily available nutrient content of soil (nitrate-nitrogen, AL-phosphorus, ALpotassium content of soil, some soil microbial characteristics (total number of bacteria and fungi, cellulose-decomposing and nitrifying bacteria, CO2-production of soil), and the amount of the plant biomass.
The readily available nutrient content of the calcareous chernozem soil increased due to the treatments, except for the change in the soil nitrate-nitrogen content, which did not measure up to the control due to the effect of high-dosage Bactofil.
The treatments also influenced the examined microbial characteristics of the soil positively. The artificial treatments significantly increased the total number of bacteria and the number of cellulose-decomposing and nitrifying bacteria. The low-dosage Bactofil significantly increased the number of cellulose-decomposing bacteria and both Bactofil dosage significantly increased the number of nitrifying bacteria. The measure of the soil respiration grew in all treatments, but significantly only in Ca(NO3)2 fertiliser treatments.
The quantity of the plant biomass was grew in a low-dosage Bactofil and significantly in the artificial fertiliser treatments. The highest plant biomass quantity was measured in the high-dosage artificial fertiliser treatment.
In the correlation analyses we found some medium positive correlation between the soil chemical, microbiological parameters examined, and the plant biomass in the case of both treatment-forms.
Based on our results Ca(NO3)2 artificial fertiliser treatments on calcareous chernozem soil proved to be more stimulating regarding the
examined soil characteristics and the amount of the plant biomass, but the low-dosage Bactofil also positively influenced the majority of the
soil characteristics examined in terms of nutrient supply. -
Significance of biogas production in Hungary
127-129Views:232It is known that the quantity of fossil energy sources are rapidly reducing, therefore it is necessary to determine a new direction which has to point directly to renewable energy sources. Increasingly comes into view the agriculture’s energy producing nature next to it’s traditional food producing one. The enviromental protection is connected to the energy production by the ultilization of biomass for energy purposes, within the biogas production has an emphasized importance. Quasi every organic material can be used in biogas production, such as: food processing by-products, manure, sewage sludge, hoousehold waste.
