Abstract Details

The number of certified organic farms is increasing, however organic matter suitable for composting is often limited in availability. Testing additional agroindustrial wastes for their suitability in composting could benefit the industry. In this project, composts produced from brewers’ spent grains/sawdust and from horse manure/sawdust were compared for their effects on yield of kale, beets, and peas. Percent of total N for untreated plots, horse manure compost and brewers’ spent grain compost amended plots were 0.2, 0.4, and 0.25 respectively. Neither compost treatment significantly improved yields in season one and brewers’ spent grain/sawdust compost significantly decreased yield in kale (P < 0.05). However in the second season kale yield was significantly increased by the horse manure compost (P = 0.03) and fresh grain additions (P = 0.05). Although the composts provided additional nutrients to the plots other factors may have attributed to the lack of significant growth benefits in season one.
