One of the main challenges in crop-livestock systems is an inefficient use of nitrogen, which precipitates a variety of negative economic, human/animal health, and environmental impacts. “The biotreatment impact assessment confirmed that proper application of biotreatment can reduce ammonia emissions from manure and environmental pollution from agriculture”. By the saving nitrogen loses priority, manure biotreatment could reduce nitrogen losses from manure and inorganic N fertilizers by approximately 5%, also could reduce approximately 5911.1 thousand tones nitrogen fertilizer in the world and reduce approximately 5.5 Eur ha−1. The maximum effect of the biodegradable compound on gaseous propagation was assessed after 28–35 days of manure storage and proved all biotreatment effect time of 49–56 days. About 32% manure biotreatment effect on reduction of ammonia emissions was established. Gas emission was obtained via laser gas analyzer using a spectroscopic method in a specially reconstructed wind tunnel chamber. ![]() Experimental research was carried out to determine significant differences of dynamics in agrochemical composition of manure, NH3 gas emissions, depending on biotreatment, manure storage duration, and ventilation intensity of the barn. (N) (number of bacterial colonies −1 × 109 cm−3), Frateuria aurentia (K) (number of bacterial colonies −1 × 109 cm−3), Bacillus megaterium (P) (bacterial colony count −1 × 109 cm−3), seaweed extract (10% by volume), phytohormones, auxins, cytokinin, gibberellins, amino acids, and vitamins) on the emission of ammonia from organic waste. In view of the reason for the agricultural waste management by formation and propagation of ammonia gas-the bacterial and enzymatic degradation of organic components in excrement-it is important to evaluate the effect of biotreatment of 100% natural composition (contain Azospirillum sp. In EU countries, the agricultural sector is the source of above 94% of the total anthropogenic emissions of ammonia, of which manure removal systems account for 56%. ![]() Increasing control of localized air pollution caused by ammonia is identified, including limiting the maximum emissions from agriculture. The use of robot scrapers in pig housings is recommended, although slight technical modifications should be made to the robot scraper. Within half an hour of observation, up to 8.2 of 120 sows were occupied with the robot scraper, but without harming it. Dry-cleaning led faster to nonslip surfaces for the sows than wet-cleaning. Even 6 h after the cleaning its effect was still visible. Although the faeces of pigs had a firmer consistency than bovine excrement, excrement quantities of up to 1.4 kg m−2 were almost completely removed. In order to assess the animals’ interactions with the robot scraper, their behaviour towards the device was observed. ![]() Selected excrement quantities removed by the robot were weighed. For evaluating the suitability of the robot scraper with regard to the cleaning performance (polluted surface area and occluded slots), the whole housing area was divided into score-squares, which were individually scored at defined intervals. The present study examined for the first time whether a robot scraper usually applied in dairy farming is usable in sow housings for cleaning the slatted floors and improving hygiene and thus animal welfare. Successful pig farming needs the best conditions of cleanliness in the housings. ![]() In SF barns, no significant difference in ammonia emission between periods with 6 manure removals per day or 0 or 1 manure removal per day was observed. The SDF barns emitted 1.0☐.2 kg NH3-N year-1 m-2 production area or 5☑% of excreted total-N or 11☒% of excreted TAN. The SF barns emitted 1.2☐.3 kg NH3-N year-1 m-2 production area (mean ± SD) or 5☑% of excreted total-N or 10☒% of excreted TAN. The on-off periods was repeated 6 times in each barn. The effect of manure removal from the slatted floor was tested in 2 SF barns applying an on-off test design, where a period of frequent manure removal was followed by a period of 0 or 1 manure removal per day. The ammonia emission was measured using the constant tracer injection technique using carbon dioxide produced by the animals as tracer. Each barn was measured 6 times over a period of a year, each period lasting 1-3 weeks. The manure was removed from the slatted floor 6 times per day and 12 times per day from solid drained floor. Four barns had slatted floor above slurry channels (SF), while four barns had solid drained floor (SDF). The mean annual ammonia emission was determined from eight naturally ventilated dairy cubicle barns.
