Changes in soil fertility

Changes in soil fertility

Code:
Result Level:
  • Outcome
Objectives:
  • Disaster Risk Reduction and Natural Resources Management
Description:

Measurement of pH, Salinity, conductivity, soil organic matter (SOM), macro and key micro nutrients in soil samples To determine effectiveness of soil fertility management interventions. Has soil fertility improved since the baseline? Is pH suitable for key crops? Is lime needed? Are there deficiencies of critical micro nutrients that are limiting crop production?

Disaggregated By:

Geography/Livelihoods zone; Wealth groups; Livelihoods group (e.g. pastoralist, farmers, traders); Period to achieve the objective;

Direction of change:
  • Increase (number)
Data source:

Both secondary and primary data collection can be used according to context. Baseline/Endline. If multiyear programme consider also a mid-term evaluation Secondary data. Reliable/relevant sources from other actors, clusters or government. Data Collection methods: Secondary data analysis; Natural resources assessment/analysis (Soil samples. Soil test kits or access to soil laboratory. Fields within the project area) Observation; Records of community meetings; Ministry records;

Sector/Subsector:
  • Livelihoods and Natural Resources Protection
  • Primary production

Measure Notes:

# of soil samples will depend on size of project, number of agro-ecological zones, soil types. Use “W” sampling pattern to take 5 soil samples from sampled field. Sample with soil auger or test pit. Collect top 30cm of soil, deeper for deep rooted crops. Dry, remove stones and organic materials (roots), mix and divide sample in half. Remix one of the halves and half again. Mix and take sample according to test kit instructions. Extract as per instructions in kit.
