Effect of heavy metal and nutrient uptake by soils in Indian Cardamom Hills

August 2012

  Indian cardamom hill soils were studied to understand nutrient and heavy metal uptake and consequent fertility level changes. Extensive cultivation of cardamom and conversion of forest land to cardamom agriculture resulted in decline of OM and lower pH. Application of chemical fertilizers in the recent past helped enhance the available phosphorus (P). This is surprisingly contrary to the general observation...

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...
