• February 27, 2020   Saturated Media Extract    Zack Grant

For decades the Saturated Media Extract (SME) test has been a routine method used for greenhouse bench crops growing in soil-less mixes and also in irrigated arid production systems. Many protected culture growers and high compost input farmers grow in media or soil that can exhibit very high nutrient levels above the capacity of the soil or media to retain those nutrients. SME represents an option to monitor and manage nutrients at the water-soluble level.
