I would like to draw the attention to the different side-products and wastes that contain lots of organic matter, micro and macro elements, and the fact that they do not have any harmful effect. These materials can be used as micronutrient fertilizers, therefore quantity of the produced CO2 and other greenhouse gases will decrease. C...ompost, sewage sludge and lime sludge were used in our experiments. The usability of these materials in crop production was examined in crop production within laboratory conditions.
The produced plants reduce the greenhouse effect because they fix CO2 that contributes to the causing of the greenhouse effect with about 50%. The production of fertilizers is not only a costly process but it needs a considerable energy at the same time. Nowadays, the reduction of the proportion of the fertilizer is significant. One...of the reasons of this is that during the production such by-products are produced in a big quantity in which the necessary vegetal nutrients can be found in a considerable measure these enrich the organic matter of soil. The latter is essential condition for the microorganisms in the soil, without which the sustainable plant cultivation can not be achieved. Besides high prices of artificial fertilizers the utilization of the wastes is economically justified. Finally the other reason for the reduction of a usage of artificial fertilizer is that the wrong use of the fertilizer may cause environmental pollutions. I examined the cultivation application of the sewage sludge in laboratory circumstances during my work.
The earth's population is growing steadily, currently accounting for about 7.3 billion people. Population growth causes food demand to rise, approximately 36 million people die each year due to starvation or related diseases. One solution to this problem is the continuous examination and development of the agricultural economy. In this study, m...atrix-assisted laser desorption/ionization time-of-flight mass spectrometer (MALDI -TOF MS) were used to analyse of sunflower, soybean and hemp. In order to analyse the protein of maize, this method has already been applied. However, for sunflower, soy and hemp, it is necessary to develop a sample preparation method. Choosing the optimal matrix solution for ionization the traget molecule is an essential part of developing the method. Our aim is to compare two different matrix solutions (α-HCCA, SA matrix), based on the properties (intensity, noise ratio, value of spectra) of the spectra.
The protection of the environment is our common task. All pollution that exposes our soils, plants or the environment – as taken in any proper or extended sense – will appear sooner or later in the food chain and in human beings who are on the top of the food-chain pyramid. The aim of our work is to give a brief overview of the effects of s...elected industrial wastes on the physiological parameters of corn plants. Sewage sludge and lime sludge were examined. These materials contain lots of useful element for plants (e.g. iron, phosphorus, potassium, zinc). However, their aluminum, chrome and lithium contents are also considerable. The element contents in sewage sludge and the filtrates of lime sludge, as well as the dry matter accumulation and relative chlorophyll contents, were measured. The disadvantageous and advantageous physiological effects of the examined materials were confirmed. The compensation effect of the environment is excluded; however, the neutralization of environmental impacts is not infinite under natural circumstances.
