Special Issue Information

Dear Colleagues,

Current agricultural practice faces challenges related to environment degradation and food security due to unsustainable customs and traditions. Realizing the sustainable development of agriculture has become a worldwide concern in line with the increasing ecological global crisis and demand for food safety. Sustainability in agriculture is fundamental to achieving the Sustainable Development Goals of the United Nations, many of which reflect the central role of soil in sustaining food, water and life. Healthy soil provides multiple ecosystem services, e.g., regulating soil nutrient cycling, reducing greenhouse gases from the atmosphere, and maintaining water quality and plant productivity. We must recognize the contribution of soil health to basic ecosystem services, food security, climate change mitigation and adaptation, and sustainable development.

To improve soil health and achieve sustainable agricultural development, we need to focus on the major threats to soil function: soil organic carbon loss, nutrient imbalance, soil erosion, soil contamination, soil acidification, and the loss of soil biodiversity. Agricultural practices should adhere more closely to the principles that govern the functioning of natural ecosystems. Appropriate agronomic technologies, such as cover crops, crop rotation, and organic amendments, need to be studied and evaluated in depth.

This Special Issue will publish papers highlighting the significance of various soil health indicators and management practices for improving soil health. Research on improving soil health, food safety, the ecological environment, and economic benefits through sustainable agronomic management will be the focus of this Special Issue. We are also interested in any research related to soil health. We welcome original research articles, technical articles, reviews, meta-analyses, and perspective articles pertaining to the relevant aspects mentioned above, even if not exhaustively.

Soil serves as the fundamental foundation for agricultural production; however, inappropriate utilization of soil in conventional cropping systems (CONV) coupled with agricultural practices focused on maximizing profit through the attainment of high-quality grain yield contributes to its degradation. An alternative to the CONV is the integrated cropping system (INTEG), which is based on sustainable plant cultivation by reducing the use of chemical pesticides and fertilizers. An interesting two-factor field experiment with winter triticale (×Triticosecale Wittm.) was conducted in 2019–2022 in south-eastern Poland. The experimental factors in this study included three winter triticale cultivars, namely Avokado, Medalion, Rotondo, and SU Liborius, and two cropping systems, CONV and INTEG. It was found that the use of the CONV brought out higher grain yield with higher protein and lower fat content. The cultivation of triticale grain under the CONV resulted in a higher thousand-grain weight (TGW), improved grain uniformity, and higher test weight values compared to INTEG. Additionally, the use of the CONV system resulted in improved values of physiological parameters (chlorophyll content and fluorescence and gas exchange), and that was caused by improved photosynthetic efficiency of triticale plants as a result of increased doses of mineral fertilizers, despite being cultivated in the INTEG; cv. SU Liborius achieved better values of yield parameters among the tested triticale cultivars grown in the CONV. Therefore, the selection of a suitable, efficient cultivar allows its growth under lower fertilization conditions and produces high grain yields of good quality. This knowledge can be valuable to farmers, as it would facilitate the selection of a triticale cultivar with the appropriate genetic profile for cultivation under specific agronomic conditions. Eventually, it would allow for the propagation of sustainable agricultural practices and contribute to enhancing soil biodiversity while maintaining the cost-effectiveness of agricultural production.

Soil structure is a crucial constituent influencing soil organic richness, rooting systems, and soil moisture conservation. Adding biochar to the soil, which directly affects aggregation, can significantly alter the soil moisture status. The extent of this impact is influenced by the temperature at which pyrolysis biochar is formed. The impact of biochar derived from wheat straw made at 350, 450, 550, and 650 °C (B350, B450, B550, B650) on soil aggregation and moisture retention was evaluated in this study. Based on the results, B550 had the largest mean weight diameter, most water-stable aggregates, and highest available water content compared to the control, with increases of 235%, 39% and 166% compared to the control. On the other hand, B350 was identified as the weakest treatment, with no significant difference from the control. Using B550 and B650 significantly reduced the soil bulk density by 13% and 12% compared to the control. Therefore, the formation of micro-aggregates, the development of soil porosity, and the subsequent increase in soil available water are unavoidable during the addition of B550. The change in the hydrophilic character of biochar and the attainment of an optimal oxygen/carbon ratio with pyrolysis degradations is a critical factor in soil hydrology issues. Full article
