Socio-economic and sharecropping influence on the adoption of practices beneficial to soil quality and nitrogen retention in Nepal

Soil degradation is a pressing issue in Nepal. The interrelation between soil degradation and nitrogen deficiency often creates feedback loops that exacerbate both problems. Further, there are debates as to whether sharecropping poses challenges to sustainable soil management. This study examines the comparative likelihood of sharecroppers and non-sharecroppers to adopt minimum or no-till, use of crop residues, incorporate fertiliser in the soil or deep placement of fertiliser, use compost and organic fertiliser, and adopt good water management practices. This study also investigates whether there are differences between adoption drivers/barriers of sharecropper and non-sharecroppers Seemingly Unrelated Regression (SUR) models are estimated. The results show that being a sharecropper is associated with a decrease in the likelihood of adopting no-tillage/minimum tillage and incorporating fertiliser rather than broadcasting. However, being a sharecropper is associated with a greater likelihood of adopting organic fertiliser, compost and crop residues. The main differences between the determinants of adoption among sharecroppers and non-sharecroppers are that older farmers were more likely to adopt certain practices for sharecroppers but not for non-sharecroppers. There are also differences in the adoption of no-tillage/minimum tillage and incorporation of fertiliser for non-sharecroppers between male and female farmers. However, for sharecroppers, male-headed farms were less likely to adopt most practices. Labour size, subsidy for synthetic fertiliser, and awareness of the soil/environment linkages also influenced adoption differently across sharecroppers and non-sharecroppers. Contrary to assertions that sharecropping acts as a barrier universally, the findings suggest that Nepalese sharecroppers' adoption of soil management practices is more context-dependent than uniformly hindered.

Towards enhanced adoption of soil‐improving management practices in Europe

AbstractSustainable agricultural soil management practices are key to restore, maintain and improve soil health. The European Joint Programme for SOIL (EJP SOIL) has identified twelve main soil challenges in Europe. To assess the potential and eventually increase the adoption of soil‐improving management practices, it is necessary to know (i) the current levels of adoption of the practices, (ii) socio‐technical barriers influencing their adoption, and (iii) their bio‐physical limits. This study compiled an inventory of soil‐improving management practices relevant to European conditions, and used a survey among soil scientists to assess the levels of adoption of these practices in Europe. In total, 53 soil management practices were identified that address one or several of the soil challenges. The adoption of most practices was low or spatially heterogeneous across Europe, highlighting region‐specific limitations to sustainable soil management. Qualitative interviews were conducted to explore the importance of socio‐technical aspects of adoption. Using conservation agriculture as an example, factors that can hinder adoption included the availability of knowledge and adequate machinery, financial risks, and farming traditions. Through a modelling approach, 54% of arable land in Europe was found to be suitable for cover cropping, indicating that the adoption of soil management practices is frequently limited by climatic constraints. We propose a region‐specific approach that recognizes the importance of identifying and overcoming socio‐technical barriers, and by acknowledging bio‐physical limits that may be expanded by innovation.

Perceptions and sociocultural factors underlying adoption of conservation agriculture in the Mediterranean

The Mediterranean region is facing major challenges for soil conservation and sustainable agriculture. Conservation agriculture (CA), including reduced soil disturbance, can help conserve soils and improve soil fertility, but its adoption in the Mediterranean region is limited. Examining farmers’ perceptions of soil and underlying sociocultural factors can help shed light on adoption of soil management practices. In this paper, we conducted a survey with 590 farmers across Morocco, Spain and Tunisia to explore concepts that are cognitively associated with soil and perceptions of tillage. We also evaluated differences in perceptions of innovation, community, adaptive capacity, and responsibility for soil. We found that farmers’ cognitive associations with soil show awareness of soil as a living resource, go beyond agriculture and livelihoods to reveal cultural ties, and link to multiple levels of human needs. Beliefs about the benefits of tillage for water availability and yield persist among the surveyed farmers. We found that openness towards innovation, perceived adaptive capacity and responsibility for soil were associated with minimum tillage, whereas community integration was not. Education, age and farm lifestyle were also associated with differences in these perceptions. CA promotion in the Mediterranean should emphasize the multiple values of soil, should demonstrate how sufficient yields may be achieved alongside resilience to drought, and be tailored to differing levels of environmental awareness and economic needs across north and south.

Factors Affecting Adoption of Sustainable Soil Management Practices among Fluted Pumpkin Producers in Ikorodu, Lagos State

Proper soil management is germane to sustainable vegetable production. The greatest threat to sustainable agricultural productivity is the declining soil productivity. The reason for this declining soil productivity might not be unconnected with the soil management practices by farmers. This study attempts to isolate factors that are contributing to vegetable farmers’ adoption of soil management practices. Primary data were collected from purposively selected 120 fluted pumpkin vegetable farmers, adopting pre-tested semi-structured interview schedule in Ikorodu Local Government Area. This is predicated on the facts that Ikorodu environment seems to be well adapted for fluted pumpkin production as many hectares of land are cultivated to fluted pumpkin by hundreds of small holders. Probit regression model was used to isolate factors affecting the adoption of sustainable soil management practices. Overall, the model predicted 85.76% of the sample correctly. The findings of the study revealed that number of economically active family members, farmers’ education, livestock holding, membership in farmer's group and credit availability were significantly positive while age of farmer negatively affect adoption of sustainable soil management practice. A unit increased in economically active family members, years of education and livestock standard unit would increase the probability of adoption of technology by 21.3, 5.8 and 7.6% respectively. Likewise, if farmers were made member in the groups and credit made available, the probability of adoption of technology would increase by 46.2 and 46.3% respectively. But a unit increase in the age of household head would decrease the level of adoption by 1.4% indicating old aged farmers do not adopt innovative technologies in agriculture.Keywords: Lagos, adoption, probit, sustainable soil management, vegetable, fluted pumpkin

Subsoil constraints to grain production in the cropping soils of the north-eastern region of Australia: an overview

In dryland agricultural systems of the subtropical, semi-arid region of north-eastern Australia, water is the most limiting resource. Crop productivity depends on the efficient use of rainfall and available water stored in the soil during fallow. Agronomic management practices including a period of fallow, stubble retention, and reduced tillage enhance reserves of soil water. However, access to stored water in these soils may be restricted by the presence of growth-limiting conditions in the rooting zone of the crop. These have been termed as subsoil constraints. Subsoil constraints may include compacted or gravel layers (physical), sodicity, salinity, acidity, nutrient deficiencies, presence of toxic elements (chemical) and low microbial activity (biological). Several of these constraints may occur together in some soils. Farmers have often not been able to obtain the potential yield determined by their prevailing climatic conditions in the marginal rainfall areas of the northern grains region. In the past, the adoption of soil management practices had been largely restricted to the top 100 mm soil layer. Exploitation of the subsoil as a source of water and nutrients has largely been overlooked. The key towards realising potential yields would be to gain better understanding of subsoils and their limitations, then develop options to manage them practically and economically. Due to the complex nature of the causal factors of these constraints, efforts are required for a combination of management approaches rather than individual options, with the aim to combat these constraints for sustainable crop production, managing natural resources and avoiding environmental damage.
