In the face of a changing climate, intensive efforts are needed for limiting the global temperature increase to 1.5 °C. Agricultural production has the potential to play an important role in mitigating climate change. It is necessary to optimize all of the agricultural practices that have high levels of greenhouse gas (GHG) emissions. Among the plant production processes, mineral fertilization is of the greatest importance in the formation of the carbon footprint (CF) of crops. There are many possibilities for reducing GHG emissions from the application of fertilizers. Further benefits in reducing the CF can be obtained through combining tillage treatments, reduced and no-till technologies, and the cultivation of catch crops and leguminous plants. Organic farming has the potential for reducing GHG emissions and improving organic carbon sequestration. This system eliminates synthetic nitrogen fertilizers and thus could lower global agricultural GHG emissions. Organic farming could result in a higher soil organic carbon content compared to non-organic systems. When used together with other environmentally friendly farming practices, significant reductions of GHG emissions can be achieved.

Given the problem of climate change and the requirements laid down by the European Union in the field of gradual decarbonization of production, it is necessary to implement solutions of reducing greenhouse gas (GHG) emissions into agricultural practice. This research paper aimed to evaluate the carbon footprint and life-cycle costs of grain maize production in various tillage systems. The material for the analyses was data from 2015–2017 collected on 15 farms located in the Wielkopolska region (Poland) and growing maize for grain in three tillage systems: conventional, reduced, and no-tillage. The life-cycle assessment and life-cycle costing methodologies were applied to assess the GHG emissions and costs associated with the grain maize production in the stages from “cradle-to-farm gate”, i.e., from obtaining raw materials and producing means for agricultural production, through the processes of maize cultivation to grain harvesting. The calculated values of the carbon footprint indicator for maize production in conventional, reduced, and no-tillage systems were 2347.4, 2353.4, and 1868.7 CO₂ eq. ha⁻¹, respectively. The largest source of GHG emissions was the use of nitrogen fertilizers. Non-inversion tillage with cover crops and leaving a large amount of crop residues in the field increased the sequestration of organic carbon and contributed to a significant reduction of the carbon footprint in maize production. The conventional tillage system demonstrated the highest overall life-cycle costs per hectare.

In light of the environmental challenges currently facing humanity, the issue of the environmental sustainability of crop production is becoming increasingly pressing. This is due to the fact that global population growth and the related demand for food are placing significant pressure on the environment. Wheat is a strategic crop globally due to its extensive cultivation area, high production and consumption levels, and vital nutritional properties. It is cultivated across diverse climatic conditions and within various agricultural production systems. It is of the utmost importance to pursue sustainable wheat production on a global scale, given the necessity to protect the environment and climate. The application of life cycle assessment (LCA) enables the identification of potential avenues for enhancing wheat production processes, thereby reducing the negative environmental impacts associated with these processes. This paper presents a synthesis of the existing literature on the environmental LCA of wheat grain production. It compares the impacts of different production systems, highlights critical stages in wheat cultivation, and provides recommendations for sustainable practices and directions for future research.

Biological plant protection is a crucial component of integrated pest management strategies. It is considered a safer alternative to chemical plant protection, with reduced risks to human health and the environment. The significance of biological plant protection has been on the rise, driven by the European Union’s mandate to decrease the reliance on chemical pesticides, the discontinuation of certain chemical active substances, and their limited availability. Microbiological plant protection products find application in organic farming systems. Among these, mycoinsecticides are prominent examples, utilizing insecticidal fungi such as Beauveria bassiana, Cordyceps fumosoroseus, C. farinosa, and Metarhizium anisopliae complex. Due to the high sensitivity of these organisms to unfavorable weather and environmental conditions, their use in the protection of field crops may not bring the desired effect. The enhancement of their efficacy may be accomplished through the use of adjuvants. Adjuvants are substances incorporated into plant protection products, including microbial insecticides, or used alone to enhance their effectiveness. They can play a pivotal role in improving the performance of mycoinsecticides by ensuring better coverage on plant surfaces and increasing the likelihood of successful pest control, thereby contributing to the overall success of biological methods of pest control. Consequently, it becomes imperative to investigate the impact of various adjuvants on the survival and effectiveness of microorganisms. Furthermore, there is no officially approved list of adjuvants for use in organic farming, the use of inadequate adjuvant may result in failure to obtain an organic certificate. The origin of adjuvants determines their classification, which significantly impacts for employment in organic farming practices. Included tables provide a list of adjuvants and additives known to enhance the efficacy of pest and disease control.
