Cotton Strip Soil Test: Rapid Assessment of Soil Microbial Activity and Diversity in the Field
Soil has always been considered as a living system due to its biological components: fungi, bacteria and plant roots. Under several ongoing research projects, we started researching how we can use ‘cotton strip assay’ to compare different cover crop mixes to optimize field soil activity and build up better soil health.
