| dc.description.abstract | In order to improve growth and productiveness of plants usually the farmers use strategies which are mainly dependent on inorganic chemical-based fertilizers. Fertilizer had caused a serious threat to human health and environment. Damages in the environment due to the intensive use of soils cause the followings: increase the loss of soil fertility and productivity, and decrease the soil organic matter In contemplation to get food safety and sustainable crop production is mandatory to look for new and healthy agricultural management system. The researches about beneficial microbes as a biofertilizer has become predominant importance in agriculture sector for their potential role achieving higher crop yields while minimizing negative impacts on the environment. The number of studies investigating the effect of organic biofertilizers is increasing because of its importance on the sustainable agriculture and environmental quality. It is well known that biofertilizers increase plant yield and improve soil fertility. However, there are few studies about the effect of biofertilizers on soil microbial biomass and enzyme activities. We hypothesized that biofertilizers increase the soil microbial activity. Therefore, I evaluated the effect of Phylazonit nutrient solution on soil respiration. To define the parameters of the samples, the effect of the applied biofertilizer and the application times in order to measure respiration with Witkamp method, we tested four treatments (categories): Control, Control + Glucose, Bio and Bio + Glucose which were tested at 2nd, 3th, 7th days. Therefore, the treatments were 12, combination of four treatments and three different days; and each treatment was replicated four times. The experimental design was completely randomized. With the measurement data of pressure loss in Witkamp method we performed an analysis of variance (ANOVA) and we compared the treatment means using the Tukey test (p£0.05) The results of the first sequence are comparable in the 2nd and 7th days while in the 3th day were not possible to observe clear difference between the treatments. On the other hand with Witkamp method was possible to see clearly the effect of the treatment in the third day. At the first set of experiments is possible to realize two groups as the induced treatments and the non-induced treatments. In case of Witkamp method we can see that the values were 37 growing continuosly. We can see that the values of the second sequence were growing continuously at both of the methods. | hu_HU |
