Phase VI – Year 1 of Implementation and Monitoring

Project overview

Number of participating farmers	Project area (hectares)	Annual SOC sequestration potential (tCO2e)
36	136	59

Implementing Institution	Centro Internacional de Mejoramiento del Maíz y el Trigo - CIMMYT Secretaría de Agricultura y Desarrollo Rural - AGRICULTURA
Region (municipality)	Michoacán, Jalisco
Main Crops	Agave; Lemon; Corn

Soil management:

Soil threats addressed	Soil erosion Soil compaction Soil fertility loss Acidification Soil organic carbon / soil organic matter loss Soil moisture loss
SSM practices implemented	Soil organic cover (e.g. cover cropping, organic mulch…) Crop diversification (e.g. crop rotation, intercropping…) Organic matter additions (e.g. manure additions, green manure, compost application, residue management…) Addition of other living organisms (e.g. bioinoculants, phytohormones, bioremediation, earthworm inoculation…)

Soil analysis:

Number of samples taken	72 samples for laboratory analysis (36 sampling stations)
Soil indicators analysed	Soil organic carbon Organic matter Total nitrogen Soil respiration Bulk density pH Nitrates P – Bray 1 P - Olsen Cations (Ca, Mg, K, Na, Al, H) Cation Exchange Capacity Soil nutrients (P, K, Ca, Mg, Na, Fe, Zn, Mn, Cu, B, S, N-NO3) Carbonates

Baseline results highlights

Soil testing revealed low hydraulic conductivity in Michoacán (0.88 cm/h in Cuitzeo and 2.8 cm/h in Huandacareo), which suggests that further testing and management for compaction and erosion should be introduced.

Trainings and workshops conducted

“RECSOIL technical training: stratification of the project area, definition of sampling design and density” - virtual – Spanish – 29 March, 31 March, 3 April 2023 - 10 participants. Participants were trained on how to collect necessary soil samples and farm activity for data, as well as how to use geospatial data to design a soil sampling strategy.

“RECSOIL field training for soil sampling and visual soil analysis” - in person - Spanish – 26-28 - 10 participants. Participants were trained on how to carry out necessary field evaluations and field sampling techniques for RECSOIL.
