Rapid, low-cost technologies generate high-value soils information for planners and farmers
A big, risky decision for smallholder farmers is what type and how much fertilizer to apply to their crops. There is lot of uncertainty about how the crops will respond, with a risk that the farmers will even lose when they harvest and sell the produce. Testing the soil beforehand and knowing how plants will respond can play an important role in reducing this risk. But the high cost and lack of access to testing services have been major bottlenecks for farmers in developing countries.
New advances in rapid, low-cost soil analytical techniques in the laboratory that simply measure light reflecting from a soil sample are reducing the cost of measuring soil properties.
