“…The SOC level and fertilizer rate impact both GHG emissions and energy indicators of the cultivation technique. The 12-year-long multiannual scientific research demonstrated that when the same fertilization technology is used on soils with different SOC levels, better results in terms of energy are obtained from soils with higher SOC content [27]. The largest share of energy in cultivation technology is comprised of mineral fertilizer and according to the data presented by different authors, it may account for 34% in no tillage [28]; 45.0-49.3% [27]; approximately 50% [29]; or as much as 53.5% [30].…”

Thus, in order to reduce GHG emissions and energy consumption in agriculture, some of the key objectives are to improve the soil quality and increase its SOC level which would allow to reduce the mineral fertilizer rates used in cultivation technologies without decreasing the fertility of crops.…”

Agricultural management, environmentally friendly technologies, chemical, organic and bio-based substances used, as well as meteorological factors, have a significant impact on the fluctuations of soil organic carbon (SOC). The aim of this research was to analyze the effect of different biopreparations on the changes of SOC content and the winter wheat and winter oilseed rape yields by assessing the energy consumption efficiency and the environmental impacts. The experimental research was conducted from 2017 to 2019 in three different treatments, in two of which were used either a molasses and magnesium sulphate based-biopreparation (T1) or a bacteria-based biopreparation (T2), while treatment T3 was applied as a control where no biopreparations were used. The dynamics of SOC content were analyzed at two depths: 0–10 and 10–20 cm. For the analysis of energy efficiency indicators and environmental impacts, the greenhouse gas (GHG) and energy consumption conversion equivalents were used. A summary of the results showed that both types of biopreparations had a positive effect on the changes of SOC content, which was especially evident in the deeper layers at 10–20 cm depth, where, irrespective of the crop type, a more significant increase of the SOC content was observed every year of the experiment compared to the control treatment. Biopreparations had a significant effect in increasing the winter wheat and winter oilseed rape yield. The best energy efficiency ratio was observed in winter wheat (4.84) and winter oilseed rape (5.11) in treatment T1. The results of the environmental impact assessment showed that the lowest GHG emissions were recorded in the winter wheat production in treatment T1 at 108.7–149.1 kg CO2eq Mg−1, while the highest were observed in oilseed rape production in the control treatment T3 at 343.4 kg CO2eq Mg−1.

“…plant material additional to the main crop, that releases nutrients for the main crop while its biomass decomposes. Crop residues from nitrogen-fixing plants grown as cover crops or green fallow preceding the main crop are considered especially sustainable N sources (Guardia et al 2019, Sarauskis et al 2019. Additional benefits of the extra biomass are the carbon input it brings to the soil (Poeplau and Don 2015) and multiple other ecosystem services like reduction of erosion and improved soil structure and microbial activity (Blanco-Canqui et al 2015).…”

We compared wheat yield, losses of nitrogen (N) in leaching, and gaseous losses as nitrous oxide (N2O) in silt and sand soil lysimeters. The studied cultivation systems were based on mineral fertilizer or mineral fertilizer together with clover green manure mulched at three different time points (August, October or May) before sowing of the main crop (either winter or spring wheat). Replacing 50–60% of mineral fertilizer N with green manure from a mixture of three clover species did not compromise the crop yield of winter or spring wheat. The results suggest that mulching of the green manure in the spring succeeding its sowing is the most beneficial practice with respect to environmental impacts. Total N leaching was higher from sandy soil than from silt loam whereas emissions of N2O were higher from the silt soil. Residual N from the clover biomass did not lead to an increase in leaching losses of N during the growing season or one year from the harvest. However, the residual N can be a source of high N2O emissions during the winter period in boreal climatic conditions.

“…doi:10.14254/2071-789X.2020 The scale of agricultural production in Poland (both plant and animal production), including relatively high consumption of agrochemicals in crop production and large livestock population poses a threat to the cleanness of water, air and soil. Intensive farming and non-sustainable fertilization exert a negative impact on the environment (Balsalobre-Lorente et al, 2019;Peoples et al, 2019;Świtek et al, 2019;Šarauskis et al, 2019). In general, it is estimated that agriculture generates 24% of the total emissions of greenhouse gases in the world, while the global food system contributes 35% of global greenhouse gas emissions.…”

The paper focuses on important and topical issues of agricultural economy development within the paradigm of sustainable development and reorientation towards a low-carbon economy. The main purpose of this study is to identify the contemporary challenges in the field of environmental protection in rural areas of Poland. Specially designed survey of a large representative sample (random sampling) of Polish agricultural producers has been used. The study is based on the results of quantitative research (questionnaire surveys) carried out among 1101 agricultural holdings and a qualitative research carried out among 24 experts (professional agri-environmental advisors). The research shows that the main challenges in the investigated material and spatial scope include lowaltitude emissions and the issues associated with waste sorting. There was a significant variation in responses, taking into account the locations of agricultural holdings as well as characteristics of the respondents and farms. Independent experts indicated and assessed environmental threats in rural areas and classified the activities and implementations in the scope of pro-environmental innovation that may reduce the negative impact of agriculture on the natural environment in rural areas of Poland.
