Soil water content profiling using EnviroSMARTTM in Northern Ghana

December 2011

Soil moisture is very important in crop cultivation. Farmers in Ghana usually cultivate crops by guessing the available moisture content of the soil by means of observation and feeling. Major drawbacks with these methods are that estimation is subjective and not exact. These methods normally lead to either soil water deficits or water logging on crop fields. The need for soil moisture profiling to understand the...
