Ascophyllum extract application can promote plant growth and root yield in carrot associated with increased root-zone soil microbial activity

by acadianplant on March 10, 2017 in Publications

 

Abstract Root growth and soil microbial activity were examined in two cultivars of carrot following treatment with Ascophyllum nodosum marine-plant extract. Field experiments were established in grower-managed fields of Maverick and Pronto carrots during 2010 and 2011. Soluble Ascophyllum extract powder (SAEP) was applied weekly, bi-weekly or tri-weekly at rates of 0 (control), 0.25, 0.50, […]
