Context specific studies on the factors influencing the adoption of organic matter management (OMM) practices on smallholder farms could be crucial for soil fertility improvement. This study aimed to understand the factors influencing the adoption of OMM practices by smallholder farmers. A hybridized theoretical framework was used to map the farmers’ adoption process. This framework states: the adoption process of OMM practices can be facilitated if an individual’s characteristics and the institutional-related factors can support it; information about the OMM practices and the required inputs are available, and he/she can apply the required technology with ease. Data collection involved observations on 100 smallholder farms, interviews with 10 smallholder farmers and 18 experts, as well as two focus group discussions with 10 farmers each. The results indicated that a composite of technical, social, cultural, and economic-driven factors influence farmer adoption of OMM strategies. These factors included the farmer characteristics of age, education status, gender, culture, and knowledge about the use and application of an OMM practice; availability of labor and inputs; availability of appropriate equipment; the existence of supportive policy framework and social support. The factors cut across the adoption components of the hybridized theoretical framework: nature of technology, farmer characteristics, and input-related, information transfer-related and institutional-related adoption factors. The study findings can inform decision-makers to make investment decisions. Future studies should assess the feasibility of the hybridized theoretical framework before experts can apply it in devising strategies for the adoption of OMM practices on smallholder farms.

Above-ground biomass cover under Coffea arabica on sloping land is beneficial but difficult to sustain. Interplanting annual and perennial legumes can sustain the above-ground biomass cover, and improve soil fertility, yield, and profitability. This was tested on 26 sloping farms in a four-growing season experiment on undersowing C. arabica with new crop combinations: Mucuna pruriens var. utilis (T1); Millettia dura Dunn (T2); a combination of M. pruriens and M. dura (T3); and the control with a no-cover legume (T4). On each farm, all treatments followed a randomized single-block design. T3 produced 8.7 mt/ha/yr above-ground biomass that was significantly (p < 0.01) higher than other treatments and was increasing with the seasons. Under T3, plant-available nitrogen (N) and potassium (K) increased more than in other treatments. During the fourth season, coffee yield in T3 was 54%, 22%, and 11% higher than in T4, T2, and T1, respectively. The gross profit under T3 was 86% higher than in T4 in the fourth season. This indicates that interplanting a combination of M. pruriens and M. dura under C. arabica on sloping land can sustainably increase above-ground biomass cover, soil’s plant-available N and K, coffee yield, and profitability. Based on the results, the combination of M. pruriens and M. dura is recommended to optimize coffee production under the described conditions.
Re-assembling land degradation: toward a nature-society-inclusive soil erosion management strategy: a case of the Rwenzori region, Uganda
(Frontiers, 2023-05-02) Kahigwa Tibasiima, Thaddeo; Bwambale, Bosco; Ekyaligonza, Deous Mary; Dietrich, Phillipp; Jumba, Francis; Freyer, Bernard; Kanahe Kagorora, John Patrick
Tackling land degradation, particularly soil erosion, remains a challenge due to the gap between science, policy, and practice which hampers the adoption of control measures by farmers. Bridging this gap requires understanding land degradation as an assemblage of the natural/biophysical and anthropogenic aspects; but also, rethinking epistemologies that level the grounds between scientists, policymakers, and farmers whose farm livelihoods are at-risk due to soil erosion. This study aimed to clarify how these requirements can be met through the lens of the recently proposed hylomorphic framework. This framework structures, in three steps, the procedure of bridging real-life experiences of farmers at risk of soil erosion with the knowledge of scientists and policymakers through the embracement of diversity in ontological realities and values, self-critiques, and coalescing overlaps in theorizations. We selected a qualitative design as most appropriate using one of the cases—the Rwenzori region—where soil erosion is high. We conducted nine focus group discussions with participants selected purposefully from three stakeholder groups including scientists, policymakers, and farmers. Following the hylomorphic framework procedure, we carried out the content analysis. Drawing on insights from this study, we elaborate on how the hylomorphic framework supports deconstructing land degradation and soil erosion, and also further offers insights into a more nature-society-inclusive soil erosion management strategy.
