ABSTRACT
The intensive/industrial growth activity of animals is one of the major sources of
greenhouse gases emissions (GHG) - 18% of the global emissions (according to the FAO estimation). The greenhouse potential of NO2 is over 300 times greater than that of CO2. It is estimated that two thirds of the agricultural greenhouse gases emissions is due to NO2 resulted from the decomposition of litter. By applying the volcanic tuff in bedding at a rate of 40% and 3-5% in compound food for turkey broilers, much of the nitrogen compounds that result from the breakdown of food protein, are retained in the pores of the adsorbent. In the absence of the absorbent, they contaminate the environment, mainly in two ways - by volatilization (about 40-50%) contaminates the atmosphere and the elution (about 25-30%) contaminate water sources. Only 20-25% of the initial nitrogen content of animal litter reaches (in terms of current technology) to be used as nutrients by plants. The beneficial action of volcanic tuff consists of massive retention of nitrogen compounds in the pores (contaminant stabilization) and their gradual release into soil, in the rate at which plants can use this source of nutrients. Thus, from a major source of pollution, nitrogen compounds from litter can become a good source of natural fertilizer, much more efficient than at present. During the realized tests, the average decrease in mortality is 18% in the experimental batch compared to the control batch. Moreover, there was a positive evolution, regarding the weight at the final slaughter, the experimental batch having a weight average with 3.8% higher than the control batch.
