N2  - Successful irrigated agriculture is underpinned by answering two
critical questions: when and how much to irrigate. This article quantifies
the role of the Chameleon and the Wetting Front Detector,
monitoring tools facilitating decision-making and learning about soilwater-
nutrient dynamics. Farmers retained nutrients in the root zone
by reducing irrigation frequency, number of siphons, and event
duration. Water productivity increased by more than 100% for farmers
both with and without monitoring tools. Transitioning smallholder
irrigation systems into profitable and sustainable schemes
requires investment in technology, farmers and institutions.
Importantly, technologies need embedding in a learning environment
that fosters critical feedback mechanisms, such as market
constraints.

and Zimbabwe through On-Farm Monitoring, Adaptive Management and Agricultural Innovation
Platforms and funded by the Australian Centre for International Agricultural Research [grant no.
FSC/2013/006]. The project was also supported by the CGIAR Research Program on Water, Land and
Ecosystems and CGIAR Fund Donors.
