Research - Posters Effect of coffee grounds on the soil nematode population of Meloidogynehaplaunder greenhouse conditions
Root-knot nematodes invade crop roots, form galls, and steal plant nutrients causing 125 billion dollars of crop loss worldwide (Ara and Hossain, 2011). Biological control methods such as compost, yard waste, and organic fertilizers can release nematicidal compounds as they decompose (McSorley, 2011). Coffee grounds are high in nitrogen, similar to other organic amendments that reduce galling from nematodes (Cooperband, 2002). When decomposing, coffee grounds release potentially-nematicidal compounds such as caffeine, tannins, and polyphenols (Yamane et al, 2014).
