Implementing New Technology

Earlier this month we had the opportunity to talk with Christy van Beek, Chief Agronomist at AgroCares and Director of the SoilCares Foundation, about the importance of using soil-scanning technology in emerging market countries like Uganda.

She gave some incredible insights on why giving farmers access to real-time information on their soil is crucial to improving yields:

Uganda, like most countries in sub-Saharan Africa, is facing an escalating soil fertility crisis and without immediate interventions, the country will continue to lose nutrients and thereby threaten its resource base. To halt and revert the trend of continuous depletion of the farmers’ most precious resource, the current practice of farming needs to be revisited. Increasing productivity while decreasing soil fertility decline demands balanced fertilization. At present, farmers are refrained from on-site information and base their fertilizer selection on intuition or on tacit knowledge and advice from local agro-dealers, without knowing the actual nutrient status of their soils. This results in a mismatch between applied nutrients and required nutrients for productive soils. More so, applying non-limiting nutrients result in economic losses and environmental degradation.

This problem can be overcome when farmers are able to base their fertilizer selection on real-time information of the nutrient status of their soils. However, in Uganda, as in many parts of the world, farmers hardly have access to reliable and specific soil information. Conventional soil test laboratories can’t give real-time information; soil samples need to be taken, sent to the laboratory and be analyzed there–a slow, expensive method, with results that are often difficult to interpret by farmers.

Recent technological innovations in IT, sensor technology and machine learning, have opened the possibility to use Near InfraRed (NIR) sensors for on-the-spot, real-time and affordable soil tests within 10 minutes using a Bluetooth connection between the NIR sensor and a software application for data interpretation on a smartphone. Hence, within 15 minutes the farmer receives a fertilizer recommendation for his specific crop selection. This innovation was first released in Kenya in 2017 by SoilCares, part of AgroCares and by now (March 2019) more than 50 organizations worldwide offer soil testing services using this technology, with considerable yield increases. Good soil management is literally at the basis of production. Farmers who test their soil and adjust their soil management accordingly build the fundament for production increase. Indeed recent evidence shows 25%-200% yield increases due to improved soil management.”

World Food Bank has recently become a strategic partner with AgroCares and has already begun utilizing the NIR technology on our Mbarara farm in Uganda.
