Failure to scale in digital agronomy: An analysis of site-specific nutrient management decision-support tools in developing countries
While many have extolled the potential impacts of digital advisory services for smallholder agriculture, the evidence for sustained uptake of such tools remains limited. This paper utilizes a survey of tool developers and researchers, as well as a systematic meta-analysis of prior studies, to assess the extent and challenges of scaling decision support tools for site-specific soil nutrient management (SSNM-DST) across smallholder farming systems, where “scaling†is defined as a significant increase in tool usage beyond pilot levels.
