Phase II continues to support projects in the three CCRP regions around issues of agroecological management and soil health so as to strengthen smallholder livelihoods and farming system resilience. The Soils team transitions from piloting and testing the soil toolkit toward design and refinement of a more usable, validated product and the public good. Toolkit outcomes will be linked with modeling and system-based analyses of farms and agroecosystems as we seek to inform larger conversations within the CCRP and beyond.
Objective 1: Refine the soil health toolkit developed in Phase I, focusing on design elements such as improved instructions, information flow to users, and ease of use, while considering options for locally sourced materials and knowledge.
Objective 2: Evaluate and quantify trade-offs of residue and nutrient management to understand implications for soil organic matter (SOM) dynamics, nutrient balances, and overall soil health in smallholder systems. These research activities aim to fill fundamental knowledge gaps in SOM and residue management, and will contribute heavily to the decision support tools and backstopping of CoP partners in the other two objectives.
Objective 3: Engage CoP and global-scale partners on soils research and sustainable cropping systems management to foster soil health, both within the three CoPs and in global-scale conversations. This occurs via activities such as research backstopping of CoP partners and agroecology hubs, formation of human capital in using the soil toolkit, and larger scale analyses that build the evidence base for sustainable smallholder management.
Outputs and Outcomes:
Adaptation, validation, and design of soil health assessment tools appropriate for different user groups
Research and modeling outputs on residue management in smallholder systems from a multidisciplinary perspective
Local, contextualized backstopping on soil health assessment and soil research for CoP projects
Participation in global dialogues with soils, assessment tool, and sustainable food systems communities of practice
A presentation made to the FRN working group about scientists’ and farmers’ assessments of soil health. It is widely acknowledged that farmers understand much about their soils. This ‘local soil knowledge’ ( LSK ) is often expressed in terms different from scientists’ soil knowledge ( SSK). Soil knowledge can be distinguished in 3 areas; this […]
Highlights: Soil tool kit pH, POXC and P correlated well with standard lab measures. Tool kit measures were able to predict maize yield as well as lab measures. Tool kit measured POM was higher after incorporation of L. purpureus residues. The tool kit can help guide soil health management in smallholder farmer contexts. Abstract Smallholder […]

The National Semi Arid Resources Research Institute (NaSARRI) conducted participatory soil health assessments with farmers in Eastern Uganda using a soil toolkit by Smallholder Soil Health Assessment https://smallholder-sha.org/. This involved working directly with farmers to determine key soil health parameters including soil pH, phosphorus, particulate organic matter, macrofaunal, and soil texture in farmers’ fields without […]
