17 pages, The purpose of the study was to design a device for the dissolution of fertilizers for agricultural use in an automatic and environmentally sustainable way to facilitate the work of farmers. To achieve this goal, an outdated blade design was used, which generates turbulent and laminar flows thanks to the angle of inclination of its blades. In tests, the combination of these two flows gave a better result compared to laminar and turbulent flows separately. The best results were achieved by varying the spin and speed, the time between spins, and the rest time. The time it would take to dissolve the mixture was drastically reduced if it were conducted in the traditional way (manually) or compared with commercial mixers. In conclusion, the technique used for the dissolution of agricultural minerals is more effective and reduces time, energy, and effort. This was able to reduce the time necessary to dissolve the fertilizer by 93 percent compared to doing it manually and by 66 percent compared to using commercial mixers, in a solution of 100 L of water per 100 kg of ammonium sulfate.
16 pages, A Danish pre-industrial farming system is reconstructed and compared to its modern industrialized farming system equivalent to evaluate agricultural performance in a sustainability perspective. The investigated Danish farm system and its contributing elements have undergone significant transformations. The intensity of contemporary agriculture shows that high productivity levels have been achieved by increasing the input of energy using modern machinery. At the same time, the energy efficiency (calculations based on energetic indicators) diminishes over time as the degree of dependence on fossil fuels increases. The results from this study show significant changes in the farming system, specifically inputs from agricultural land use, livestock, and energy systems. From being highly circular, the system changed to being a clear linear farming system with highly increased productivity but less efficient at the same time, questioning the relationship between productivity and efficiency and resource utilization in modern farming systems. Through utilizing an agroecological historical approach by comparing system performance over time, the results offer opportunities to explore how agricultural farming systems evolve over time and help to describe the complexity of the system level in a sustainability perspective.

9 pages, Despite agriculture’s great potential to Tanzania agricultural development, the sector faces diverse challenges. For example, existence of gender gaps in accessing agricultural production resources and benefits obtained from the same impede the sector’s growth. Therefore, adoption of conservation agriculture (CA) has been seen as one of the measures to address the sector limited productivity. Nonetheless, there is limited knowledge on how CA has managed to reduce gender inequalities in accessing both reproductive resources and benefits accrued from agriculture. This paper examines gender gaps in conservation agriculture programme implemented by Sustainable Agriculture in Tanzania (SAT), by specifically analyzing gender participation and relations in CA in Morogoro municipality and Morogoro district. This study adopted a mixed method approach whereby both qualitative and quantitative data were collected from four sites where SAT implements its activities. Findings show that CA has significantly reduced gander gaps in accessing production resources and services as well as raising women’s participation in decision making with regards to production and use of income obtained from sales of produce. Farmers regardless of the gender can access extension services, and credit, and are involved in various initiatives collectively. Despite the economic benefits, findings show that CA is laborious and takes much of farmers’ time, women being more affected. Therefore, it is recommended that the central and local governments and various stakeholders should promote the spread of conservation agriculture technologies since it reduces the biasness in agriculture and empowering women. Ensuring access to advanced cheap technologies to farmers. Nonetheless, there is need to ensure that female farmers are not overburdened in the process.
