Special Issue Information

Dear Colleagues,

Demand for food production is increasing because of the increasing population and quality of life. One of the main factors enabling the increasing demands on the volume and quality of production to be met is intensive agriculture, which has been gradually introduced since the second half of the 20th century. However, the intensification of agriculture brings more intensive production of waste and other pollutants, negatively affecting the environment and reducing the quality of life in the vicinity of agricultural holdings. Using so-called end-of-pipe technologies, which try in various ways to limit the discharge of already generated waste substances into the environment, does not lead to a successful goal. Therefore, efforts are being made to use technologies and technological practices in intensive livestock farming to prevent such substances' formation. This effort is formulated as integrated pollution prevention and control (IPPC).

Intensive livestock farming is a source of gaseous emissions, which have a negative impact on the welfare of breeding animals, human health, and the environment. These influences of modern intensive agriculture have led to numerous protocols, national regulations, and directives that monitor individual farms, publishing tools for estimating gaseous emissions and issuing technical measures to reduce them. The underlying assumption is that preventive measures will reduce pollution. To enable any effective implementation in this area, it is essential to understand the risk, production, and monitoring of gaseous emissions.

This Special Issue is open to submissions on strategies and approaches to monitoring or predicting gas emissions from the whole process of agricultural production. Contributions to determining gas emissions from animal housing, manure storage, landspreading management, crop production, composting, biogas production, product processing, etc., are welcome. From a precision agriculture perspective, estimating gas emissions using computer models or intelligent systems, as well as their impact on animal welfare, and managing microclimatic conditions on the farm are topics of interest.

Biochar application has the potential for mitigating N2O emissions from agricultural soils and has been suggested as a management practice to ameliorate soil fertility and increase crop productivity. Nevertheless, the influence of biochar addition on N2O emissions from soils with different pH levels is not yet clear, which results in a poor understanding of the mechanisms regarding biochar application to soil N2O mitigation. A 40-day incubation experiment was carried out in the present study to investigate the impact of biochar on N2O emissions from soils with different natural pH. Four treatments (control, nitrogen fertilizer application, biochar amendment, and N plus biochar amendment) were set up separately in soils with three different natural pH levels (acidic vegetable soil, neutral rice soil, and alkaline soil). Our results showed that adding biochar significantly decreased N2O emissions by 20.8% and 47.6% in acidic vegetable soil for both N and no N addition treatments, respectively. For neutral and alkaline soils, the reduction of N2O emissions by biochar amendment was only significant for N addition treatments in alkaline soil. Soil pH and NO3-N concentration were significantly affected by biochar amendment (soil pH increased by 1.43–1.56, 0.57–0.70, and 0.29–0.37 units for acidic vegetable soil, neutral rice soil, and alkaline soil, respectively). Thus, biochar amendment could be used as an effective management practice for mitigating N2O emissions from acidic and alkaline soils. Full article
