This policy brief presents results from a randomized controlled trial that compares the effectiveness of a 1-day training against a 2-day training on sustainable soil management. The training was targeted at smallholder rice farmers. The second day of the 2-day training focused on soil testing using a rapid low-cost soil test kit (PUTS). Both training groups are also compared to a benchmark scenario where farmers do not get any training. Specifically, the evaluation addresses the following questions:
- Do small-scale rice farmers change their soil fertility management behavior in response to training?
- Does training on and access to soil testing increase the effect of training?
- Does training increase farmers’ knowledge around soil nutrient management?
