The main purpose of this paper was to present ammonia (NH3) emissions from agriculture, on a regional scale, in 2017, and identify recommendable agricultural practices limiting ammonia emissions. The methodology used to estimate emissions was based on the approach of the National Centre for Emissions Management (KOBiZE). Analyses were based on statistical data of Statistics Poland (GUS), from 2017. The results of the conducted study showed significant spatial differentiation of ammonia emissions from agriculture. The region of Wielkopolska had the highest NH3 emissions at a level of 34.5 kg NH3 per ha UAA. Lower ammonia emissions were identified in the following regions: Kujawsko-Pomorskie, Łódzkie, Mazowieckie, Podlaskie and Warmińsko-Mazurskie, between 20.3-24.7 kg NH3/ha UAA. In total ammonia emissions from agriculture, in Poland, 76.8% constituted emissions from the management of natural fertilisers. The Wielkopolskie and Podlaskie voivodships have a majority share in the emissions of ammonia from animal production – 29.1 and 21.3 kg NH3/ha UAA, respectively. Whereas, ammonia emissions from plant production in 2017 was 66 Gg, which equals 4.6 kg NH3/ha UAA. The highest emission of ammonia from plant production was detected in the Kujawsko-Pomorskie, Opolskie and Dolnośląskie voivodships, in regions characterized by the most intensive crop production. Estimated emissions were 6.9, 6.2 and 6.0 kg NH3/ha UAA, respectively. A reduction of ammonia emissions from agriculture can be obtained through the proper maintenance of livestock and natural fertilisers, and the implementation of low-carbon methods of the application of mineral nitrogen fertilizer.

The aim of the study was to present ammonia emissions from animal production on a regional scale in 2016. Emission estimates in particular regions were based on methodology developed by EEA in 2016 and applied in Poland by The National Centre for Emissions Management (NCEM). The conducted analyses were based on the size of livestock population, farming system and emission factors at every stage of manure management. The analysis showed substantial spatial differentiation of ammonia emissions from animal production. Voivodships that accounted for the biggest share in emissions from cattle farming were as follows: Mazowieckie, Podlaskie and Wielkopolskie. Estimated emissions in these voivodships amounted to: 47.4, 32.8 and 21.7 Gg NH3, respectively. The highest levels of ammonia emissions from pig production were identified in the region of Wielkopolska. Ammonia emissions in this voivodship amounted to 16.2 Gg NH3. The Wielkopolska region is also distinguished by the highest ammonia emissions from poultry production. The emissions equaled 11.4 Gg NH3 and accounted for 24.1% of total emissions in this region. The realization of reduction commitments for ammonia imposed by the NEC Directive depends on the introduction of a set of changes in livestock production: regarding the housing method, animal nutrition, fertilizer storage and application as well as dissemination of good agricultural practices aiming at ammonia emission reduction.

The main source of ammonia emissions in Poland is agriculture. In 2017, approximately 94% of the total ammonia emissions in Poland came from agriculture, of which the largest part (78%) was related to livestock manure and 22% to nitrogen fertilization. This study presents the results of representative research on the implementation of technologies and techniques that reduce ammonia emissions on farms in Poland. The research methodology, including statistical data analysis (multiple correspondence analysis), allowed comparisons to be made of the applied low-carbon practices, taking into account farmers’ characteristics (e.g., age and education) and farm attributes (area size, location, etc.). According to the research, both in the case of mineral fertilization and animal production, farmers in Poland relatively rarely undertake pro-ecological practices aimed at reducing ammonia emissions. The most frequently undertaken activities include dividing the doses of nitrogen fertilizers (in terms of plant production) and the use of feed additives (in terms of livestock production). Empirical studies, supported by correspondence analyses, confirmed a significant differentiation of coexistence and strength of the relationship between the studied variables. The use of correspondence analysis made it possible to precisely recognize the differentiation and co-occurrence of variable categories. In the course of analytical work, a relatively strong correlation was found between the use of divided doses of nitrogen fertilizers and the economic size of farms (φ2 = 0.11571). In turn, the use of feed additives was most strongly determined by the economic size of farms (φ2 = 0.072614) and the location of farms (φ2 = 0.072223).

AbstractMicrobial activity is an integral part of an agricultural ecosystem and influences the quality of agricultural commodities. Microbial ecology influences grapevine health and crop production, conversion of sugar to ethanol during fermentation, thus wine aroma and flavour. There are regionally differentiated microbial patterns in grapevines and must but how microbial patterns contribute to wine regional distinctiveness (terroir) at small scale (<100 km) is not well defined. Here we characterise fungal communities, yeast populations, and Saccharomyces cerevisiae populations during spontaneous fermentation using metagenomics and population genetics to investigate microbial distribution and fungal contributions to the resultant wine. We found differentiation of fungi, yeasts, and S. cerevisiae between geographic origins (estate/vineyard), with influences from the grape variety. Growth and dominance of S. cerevisiae during fermentation reshaped the fungal community and showed geographic structure at the strain level. Associations between fungal microbiota diversity and wine chemicals suggest that S. cerevisiae plays a primary role in determining wine aroma profiles at a sub-regional scale. The geographic distribution at scales of less than 12 km supports that differential microbial communities, including the dominant fermentative yeast S. cerevisiae can be distinct in a local setting. These findings provide further evidence for microbial contributions to wine terroir, and perspectives for sustainable agricultural practices to maintain microbial diversity and optimise fermentation function to craft beverage quality.

The Impact

The growing world population and the necessity to meet its nutritional needs despite the limited area of agricultural land pose a serious challenge for agriculture. Agriculture is responsible for 80–95% of total ammonia emissions to the atmosphere, but at the same time it has great potential to reduce them. Fertilisation with mineral nitrogen (in particular urea) is responsible for 19.0–20.3% of total ammonia emissions emitted from agriculture. Ammonia emissions have a negative impact on the environment and human health, therefore it is important to minimize the volatilization of ammonia and increase fertiliser efficiency. This is important due to the need to mitigate the negative impact of anthropopressure on the environment in terms of air pollution, negative effect on soils and waters. The application of urease inhibitors during fertilisation with nitrogen fertilisers is one method to reduce ammonia emissions from plant production. Another option to achieve this goal is to reverse the global trend toward maximizing the production of energy crops (intensive fertilisation inevitably increasing ammonia emissions to the environment) for the production of biofuels, which is growing rapidly, taking up arable land that could be used for food production. The aim of the review is to identify the impact of recently introduced technologies for reducing ammonia emissions from urea on agricultural productivity, environment, and crops. It is of importance to reconsider optimization of crop production in arable land, possible owing to the progress in the production, modification, and application of mineral fertilisers and changes in crop structure. A broad debate is necessary with policymakers and stakeholders to define new targets allowing introduction of technologies for conversion of energy crops into energy with a minimal impact on food production and environmental issue.

Irreversible Damage

The use of unsustainable levels of chemical fertilizers and plant protection chemicals has resulted in a steady decline in soil and crop productivity the world over. Soil biology has undergone irreversible damage, coupled with a high concentration of toxic chemical residues in plant tissues and human bodies. Agricultural practices must evolve to sustainably meet the growing global demand for food without irreversibly damaging soil. Microbial biocontrol agents have tremendous potential to bring sustainability to agriculture in a way that is safe for the environment. Biopesticides do not kill non-target insects, and biosafety is ensured because biopesticides act as antidotes and do not lead to chemical contamination in the soil. This article is part of a larger study conducted in Ukraine by researchers at the Université de Montréal with the support of Mitacs and Earth Alive Clean Technologies. The responses of farmers who use biofertilizers (“user farmers”) and those who do not (“non-user farmers”), along with the responses of manufacturers or suppliers of biofertilizers, and research and development (R&D) scientists are captured to demonstrate the advantages of applying microbial biopesticides to field crops. Participants reported a 15-30% increase in yields and crop production after the application of biopesticides. With the use of biopesticides, farmers cultivated better quality fruits, grains, and tubers with a longer shelf life. Moreover, while the risk of crop loss remains high (60-70%) with chemically grown crops, this risk is reduced to 33% on average if crops are grown using biopesticides. The findings indicate that a large proportion of farmers would prefer to use biopesticides if they are effective and high quality products. In this context, the quality and effectiveness of products is therefore very important. Despite their benefits to soil, human health, and ecosystems, biopesticides face significant challenges and competition vis-à-vis synthetic pesticides for a variety of reasons. Therefore, the development of biopesticides must overcome the problems of poor quality products, short shelf life, delayed action, high market costs, and legal/registration issues.

From a ‘farm to fork’ perspective, there are several phases in the production chain of fruits and vegetables in which undesired microbial contaminations can attack foodstuff. In managing these diseases, harvest is a crucial point for shifting the intervention criteria. While in preharvest, pest management consists of tailored agricultural practices, in postharvest, the contaminations are treated using specific (bio)technological approaches (physical, chemical, biological). Some issues connect the ‘pre’ and ‘post’, aligning some problems and possible solution. The colonisation of undesired microorganisms in preharvest can affect the postharvest quality, influencing crop production, yield and storage. Postharvest practices can ‘amplify’ the contamination, favouring microbial spread and provoking injures of the product, which can sustain microbial growth. In this context, microbial biocontrol is a biological strategy receiving increasing interest as sustainable innovation. Microbial-based biotools can find application both to control plant diseases and to reduce contaminations on the product, and therefore, can be considered biocontrol solutions in preharvest or in postharvest. Numerous microbial antagonists (fungi, yeasts and bacteria) can be used in the field and during storage, as reported by laboratory and industrial-scale studies. This review aims to examine the main microbial-based tools potentially representing sustainable bioprotective biotechnologies, focusing on the biotools that overtake the boundaries between pre- and postharvest applications protecting quality against microbial decay.

The Cost

In many circles, brown coal continues to be viewed as a cheap source of energy, resulting in numerous investments in new opencast brown coal mines. Such a perception of brown coal energy is only possible if the external costs associated with mining and burning coal are not considered. In past studies, external cost analysis has focused on the external costs of coal burning and associated emissions. This paper focuses on the extraction phase and assesses the external costs to agriculture associated with the resulting depression cone. This paper discusses the difficulties researchers face in estimating agricultural losses resulting from the development of a depression cone due to opencast mineral extraction. In the case of brown coal, the impacts are of a geological, natural-climatic, agricultural-productive, temporal, and spatial nature and result from a multiplicity of interacting factors. Then, a methodology for counting external costs in crop production was proposed. The next section estimates the external costs of crop production arising from the operation of opencast mines in the Konin-Turek brown coal field, which is located in central Poland. The analyses conducted showed a large decrease in grain and potato yields and no effect of the depression cone on sugar beet levels. Including the estimated external costs in the cost of producing electricity from mined brown coal would significantly worsen the profitability of that production.

The depletion of fossil fuels and climate change concerns are drivers for the development and expansion of bioenergy. Promoting biomass is vital to move civilization toward a low-carbon economy. To meet European Union targets, it is required to increase the use of agricultural residues (including straw) for power generation. Using agricultural residues without accounting for their energy consumed and carbon dioxide emissions distorts the energy and environmental balance, and their analysis is the purpose of this study. In this paper, a life cycle analysis method is applied. The allocation of carbon dioxide emissions and energy inputs in the crop production by allocating between a product (grain) and a byproduct (straw) is modeled. Selected crop yield and the residue-to-crop ratio impact on the above indicators are investigated. We reveal that straw formation can consume between 30% and 70% of the total energy inputs and, therefore, emits relative carbon dioxide emissions. For cereal crops, this energy can be up to 40% of the lower heating value of straw. Energy and environmental indicators of a straw return-to-field technology and straw power generation systems are examined.

Food And Feed

By 2050, 9.8 billion people are projected to live on Earth, which means that we need to double our current food production to keep pace with such a large population increase. In addition, rising greenhouse gas emissions and the associated climate change are placing a significant strain on the planet’s ability to sustain itself. However, in order to increase the quantity of proteins of plant origin, it is necessary to increase crop production areas, harvesting frequencies and the quantity of crops produced. Unfortunately, the optimization of these factors is already very close to the available maximum in the current situation. The developed cultivation systems and maximum utilization of the soil power leads to very serious environmental problems, soil destruction, loss of biodiversity and serious environmental pollution through the transport of the produced plant raw materials. This poses a serious challenge to food security and further increases the risk of hunger. There is therefore a need for agricultural practices that can lead to the cultivation of food and feed crops that have better sustainability indicators and are more resilient to climate change, which can be used to safely produce health-promoting feeds, as well as novel and value-added foods. Within this group, a particular problem is presented by the protein supply of the population, as currently about one billion people do not have adequate protein intake. However, conventional protein sources are not sufficient to meet growing protein needs. As mentioned above, food and feed proteins are based on plant proteins. In recent years, a prominent role has been played by the research into alternative proteins and the mapping of their positive and negative properties. Among alternative proteins, special attention has been paid to various yeasts, fungi, bacteria, algae, singe cell proteins (SCPs) and insects. In this paper, we focus on the presentation of algae, particularly microalgae, which are of paramount importance not only because of their significant protein content and favorable amino acid composition, but also because they are also sources of many valuable molecules, such as polyunsaturated fatty acids, pigments, antioxidants, drugs and other biologically active compounds. It is important to learn about microalgae biomass in order to be able to develop innovative health food products.

Introduction. The intensification of globalization processes that characterize the beginning of the new millennium has led to the emergence of supranational structures of regional and global scope. The deepening of Ukraine's integration into the international trading space causes new opportunities and threats. The relatively large size of the territory of Ukraine as a European state and its administrative structure causes a number of differences in the socio-economic development of its regions. Identifying regional differences in foreign trade in agri-food products and their causes is an urgent task of the study, given the leading role of the agro-industrial sector in Ukraine's foreign trade. The aim of the study is to identify regional differences of foreign trade in agri-food products and identify their causes. Results of work. The analysis results of foreign trade in agro-food products on the average for 2016-2018 by regions are given. It is determined that the four leading export regions are Mykolaiv, Odesa, Kyiv and Vinnytsia, as they account for about 47,9 %. The regions were evaluated according to the following indicators: the volume of regional exports, the volume of production of cereals and legumes, the production of sunflower seeds. According to the results of the analysis, each region was assigned a corresponding rank, on the basis of the values of which the correlation coefficients of the regions ranks were calculated. It is determined that there is a close link between the region's place in the national agri-food export ratings and the production of cereals and legumes; and there is a median link between the region's place in the national agri-food export and sunflower seed ratings. Imports of agro-food products by regions are considered, where Kiev region is the absolute leader, which together with Odessa, Lviv and Dnipropetrovsk regions have 64.5 % of all corresponding imports. The analysis of agro-food products import by groups of goods is presented. The regions ranking by import volumes of agri-food products and disposable income per person has been done. The obtained coefficient of correlation of ranks testifies to the average degree of relation close to high. Conclusions. It is proved that the differences in the volumes of crop production mainly cereals, legumes and sunflower are the basis for regional differentiation of agricultural food exports, which testifies to the raw nature of exports, stagnation of livestock and unsatisfactory development of the domestic food industry. Differentiation of imports of agro-industrial products is caused by the difference in income of the population by regions. Keywords: agro-food products, export, import, balance, production, raw materials, processing, disposable income.
