  This paper focuses on the corporate environmental performance and its motivating factors. The background of the study is a questionnaire survey covers 82 Hungarian manufacturing companies. The identification of the environmental performance based on the study of György Pataki and László Radácsi who create a group of environmental indicators. The motivating factors are several stakeholders of the companies who have affect on an organization's environmental actions. These motivations can be divided into internal and external factors. According to the questionnaire survey the combination of internal and external factors seems to the most important to the better environmental performance.

  that the world of business, profit and work is not a hermetically closed area, but is in interaction with its closer and wider surroundings, ultimately with society and the natural environment.
  The affectedness of each sector and company varies. To be able to tackle these problems, first and foremost the commitment of companies towards environmentally conscious attitude is necessary, which can form as a result of inner obligation or outer pressure. Thus companies will be concerned to measure and quantify the environmental effects of all activities.
  Some of the companies have already given their votes for environment-protection. Both internationally and at home it seems that the responsible leaders of more and more companies build social, human rights and environmental protection considerations in the objects and values of the company apart from profit maximization.
  In my thesis I present the data gathered from a questionnaire survey carried out with food-industry companies in the Northern-Plain Region. The aim of the survey was to evaluate the commitment of companies towards environmental protection via solid data. The fact that more than half of the respondents found the positive effects of environmental protection of little importance and that environmental protection was the last among the aims of some companies reflected greatly in the following outcomes.

  In Europe, there has been a significant change in the way tillage is approached in recent years. This change is due to a growing awareness among farmers, politicians and society as a whole that soil is not a renewable resource in itself. From an agricultural point of view, the greatest impact on soil condition can be achieved through the use of the applied tillage systems.  My research takes this approach as a basis when examining the different tillage systems and their impact on the environment. In this context, conventional and a variety of no-tillage systems are examined in this paper. As a next step, it is examined how the environmental conditions created by the different tillage systems influence the emergence of maize hybrids. The analyses are carried out in a multi-factorial, long-term tillage field experiment. The same batch of the same hybrid seed was sown in several crop years, and the effects of environmental conditions on the emergence process were examined. Environmental effects and emergence-related uptake were measured in the examined plots. Measurements of environmental effects included air temperature, precipitation, soil temperature measured at seeding depth, as well as % cover of stem residue on the surface in the treated plots. The first emergence time measurements of the sown crop in the plots of each treatment were compared and relationships between these factors were investigated.

  Recent years have seen an increasing emphasis on child-friendly concepts in landscape architecture and urban planning, as well as a growing emphasis on school grounds and environmental education, both in terms of pedagogy and landscape design. School grounds provide places for active engagement with the environment, for experiencing what is taught in class, and, are therefore of particular importance for education and for building children's connection with nature. The aim of this research is to develop a set of landscape architecture tools that can be used to promote child-friendly and education-centered design of school grounds. The research collects and organises the different school ground features, drawing on literature research, and the analysis of the Framework Curriculum. The toolkit presented in this paper lists and evaluates each feature according to its function, its relevance to school subjects and the specific knowledge or skills it can help to acquire, its space requirements and feasibility. To conclude, school grounds offer opportunities for teaching almost any subject and can therefore be linked to educational activities in multiple ways. The results of this research are to be developed into design guidelines in order to be used by designers and teachers alike, to help develop school grounds contributing to the well-being and environmental awareness of new generations.

• Effect of soil-compost proportion on the abiotic and biotic parameters of soilplant system

  The environmental awareness, coming to the front in the 21^st century, motivates us to supply the plant nutrient demand (in point of the plant, the environment and the human health) with natural materials.
  Composting is known since the beginning of civilization. We came to know more the processes of composting as a result of last decades’ research, but numerous unexplained questions remained up to this day. The good compost is dark gray or brown, and it should not create an odor. It has aggregate structure, and it’s pH is neutral. Compost is soil-like (Fehér, 2001), nutrient-rich material, which contains valuable nutrients extracted from soil, so if we recycle this, we can decrease the chemical fertilizer and other (example: mineral energy) expenses.
  The reason of that we chose the more accurate cognition of compost utilization is to do more effective the site-specific nutrient supply. This increases the average yield and the quality of yield. Besides we can decrease the harmful effects, which endanger the plant, the environment, and the human body.
  During the compost utilization experiment we blended the  acid sandy soil with compost in 4 different volumetric proportions (5 treatments) than we set the pots randomized. The advantage of this method is that we can provide equal conditions for plants so we can measure the effect of  treatments correctly. Our experimental plant was ryegrass (Lolium perenne L.), that grows rapidly, tolerates the glasshouse conditions, and indicates the effect of treatments well. After the harvest of ryegrass we measured the fresh and dry weight of harvested leaves and the total C-, N-, S-content of the dry matter and of the soil, we examined the pH and the salt concentration of  soil as well. 
  Our aim was to study and evaluate the relations between the compost-soil proportion and the nutrient content of soil and plant. In our previous experiments we confirmed (based on variance analyses) that the compost has a beneficial effect on soil and increases the nutrient content of the soil (Szabó, 2009). But it’s important to appoint that the compound of compost is seasonally change: in winter the selective gathered municipal solid waste contains salt that were applied for non-skidding of roads, but salt has a negative effect to the plant. We proved that in our experiment the 25/75% compost/soil proportion was ideal for the plant. This content of compost effected 6 times higher green matter weight compared to the 100% sandy soil.

  This paper intends to give an overview on some results of our studies carried out on the public opinion of the above aspects (settlements’
  comfort level and the use of renewable energy sources) directly or indirectly linked to the topic of climate change and possible adaptations.
  These studies were carried out by applying questionnaire survey in the (altogether 25) settlements of the Gyöngyös Micro-region.
  Knowledge on general human perceptions related to climate change and its impacts is considered to be important as it should advance the
  elaboration of adaptation and applied scientific works. They are highly required as rural areas, due to their closer relationship (dependence)
  to the physical environment, are more susceptible to changes resultant from the climate change with their possibilities to adaptation also
  being impeded.
  The beauty of environment plays an important role in the settlements studied within the micro-region with more than two third of pollees
  opting the environment as a factor they most proud of, especially among those residing in the villages for more than 10 years. It can be
  presumed that any change in this environment would greatly impact their everyday life and emotional relationship to their home villages. The
  overall picture after analysing the public opinion on the use of renewable energy source (as possible way of adaptation to the impacts of
  climate change) is rather controversial. Even basic knowledge and information are limited regarding the relevant technologies calling
  attention to the importance of raising environmental awareness and providing full information seems to be essential and should be
  implemented, through the media and education.
