Abstract

This study was conducted to test the effects of a sponsored fertilizer containing micronutrients on Kentucky bluegrass and creeping bentgrass. The data was collected on the shoot and root growth, turf performance and tissue nutrients within the shoot system. The root system in the turf pots with no additional NPK started to decline after the second trial and was therefore harvested. The turf pots receiving NPK continued in the trials. The results show that both species NPK fertility rates and rootzone had a great effect on root growth. 2 of the creeping bentgrass treatments had a greater number of shoots and root growth than the Kentucky bluegrass. Overall the liquid carboxy used in treatments had a greater increase on the chlorophyll index, root growth and shoot growth than the other treatments.
