The aim of this study was to provide an overview of the approaches and methods used to assess the dynamics of soil organic matter (SOM). This included identifying relevant processes that describe and estimate SOM decomposition, lability, and humification for the purpose of sustainable management. Various existing techniques and models for the qualitative and quantitative assessment of SOM were evaluated to gain a better understanding of advances in organic matter transformation. This evaluation aimed to identify the strengths, limitations, and applications of these techniques and models, and to highlight new research directions in the field. Quantitative analysis of SOM can be performed using various parameters, including oxidation kinetics, lability, carbon management index, humification degree, humification index, and humification ratio. On the other hand, qualitative evaluation of SOM can involve techniques such as oxidizability, high-performance size-exclusion chromatography, electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry, visual examination, smell, assessment of microorganism content, plant growth, cation exchange capacity, type of organic material, and decomposition. These techniques and parameters provide valuable insights into the characteristics and transformation of SOM, enabling a comprehensive understanding of its dynamics. Evaluating SOM dynamics is of utmost importance as it is a determining factor for soil health, fertility, organic matter stability, and sustainability. Therefore, developing SOM models and other assessment techniques based on soil properties, environmental factors, and management practices can serve as a tool for sustainable management. Long-term or extensive short-term experimental data should be used for modeling to obtain reliable results, especially for quantitative SOM transformation analysis, and changes in the quality and quantity of SOM should be considered when developing sustainable soil management strategies.

The demand for wheat production is increasing and is associated with environmental effects. To sustain the increased demand, there is a need to find sustainable methods of wheat production. The choice of cropping system can significantly affect the environmental burden of agricultural production systems. This study presents the results of monitoring emission loads resulting from winter wheat cultivation under different cropping systems: organic unfertilized (ORG), organic fertilized (ORG-F), conventional unfertilized (CON), and conventional fertilized (CON-F). The system boundaries include all the processes from “cradle to farm gate” and the functional unit was 1 kg of wheat grain. The primary data were obtained from experimental field trials and secondary data from Ecoinvent v3.5, WFLDB, and Agri-footprint v5.0 databases. The results of this study are related to eight impact categories. The SimaPro 9.2.0.1 software and ReCiPe Midpoint (H) V1.13/Europe Recipe H were used for calculation. The results show that fertilized variants recorded higher environmental impacts compared to the unfertilized variants. The results indicate that ORG-F was more environmentally friendly compared to the CON-F variant at the expense of lower yields. Overall, ORG imposes the lowest environmental impact and is deemed to be more environmentally friendly.

Carrot cultivation in south-eastern Nigeria could reduce the need to transport carrots from northern regions. To explore this, a field experiment with three replications was carried out in Nsukka, south-eastern Nigeria, focusing on four carrot varieties (Carotte Touchon, Touchon Mega, Super Mega, and Touchon France) and three poultry manure rates (0, 10, and 20 t ha⁻¹). The study revealed that Carotte Touchon had the highest root production (11.6 t ha⁻¹) with 20 t ha⁻¹ of manure, followed by 7.5 t ha⁻¹ at 10 t ha⁻¹, while Touchon Mega had the lowest root yield (1.4 t ha⁻¹) in the control group. Proximate quality of carrots was mostly unaffected by the varieties, except for fat content. The study found significant variations in vitamins A, C, and E, phytochemicals (phytate, tannins, and oxalate), and minerals (Fe, Mg, Na, and K) among the varieties, although no impact on Zn and Ca was observed. This research suggests that carrots have substantial growth potential in south-eastern Nigeria, offering a solution to vitamin and mineral deficiencies prevalent in this area. Additionally, Carotte Touchon with either 20 t ha⁻¹ or 10 t ha⁻¹ of poultry manure is recommended for optimal carrot cultivation in this region.

Conflicts between crop farmers and herdsmen in Nigeria have intensified in recent decades, posing a danger to agricultural sustainability, rural livelihoods, and food security. This study investigated coping strategies that arable crop farmers have adopted in Enugu State, Nigeria, against herders’ incursions. Data were collected through the use of a structured questionnaire. According to the result, herders’ activities, including crop destruction, assaults on women, and intimidation, have severely affected livelihoods, which has resulted in reduced income and declining productivity. In response, most farmers applied some measures such as fencing, group farming, and cultivating small plots near homesteads to avoid clashing with the marauding Fulani pastoralists. Among all the measures adopted by the farmers, results reveal that only collective strategies, such as group farming and cultivating small plots close to homesteads, were sustainable. The study pointed out the limited capacity of rural households to cope alone and suggested the need for government assistance, such as the provision of less expensive protective infrastructure and stronger community security arrangements. The study recommends that the government should ensure and employ conflict management strategies through empowering traditional institutions with delegated legislation to ameliorate further occurrences. The research contributes to the body of literature by revealing the farmers’ viewpoints and strategies within the broader discourse on farmer–herder conflicts in Nigeria.

In the agricultural sector, where factors like the type of agriculture, management techniques, and access to funding are critical, disadvantaged people face significant barriers to employment. This study investigated the effects of these factors, especially with regard to sustainability and social farming, on the employment of disadvantaged persons in the Czech Republic. We sent questionnaires to 2036 agricultural businesses within the Czech Republic, and the data we received were sorted and analyzed. There was a favorable relationship between farm size and employment chances. Disadvantaged people were more likely to be hired by large farms, especially those larger than 250 hectares. Furthermore, mixed-production farms were more capable of employing disadvantaged persons, unlike conventional farms, which reached their maximum employment levels at one, three, or six workers. Organic farming had a more even distribution, while biodynamic farming showed limited capacity to employ disadvantaged persons. Farms involved in fundraising had fewer farms but employed more disadvantaged persons (number of employees peaked at two, four, and six), while farms that did not engage in fundraising hired more disadvantaged individuals (peaked at one and three employees). The motivations for employing disadvantaged persons were primarily social concerns, as well as labor shortages and economic and innovative factors. These findings show the importance of agricultural enterprises using these factors to improve the social and economic well-being of disadvantaged persons.
