To examine the effect of a mulching sheet made of nonwoven fabric on the colonization of roots of weeping love grass, Eragrostis curvula (WLG), by arbuscular mycorrhizal (AM) fungi, both laboratory and field experiments were conducted. In the laboratory experiment, the effect of mulching on the growth of WLG was examined in combination with an AM fungal inoculum containing Gigaspora margarita and slow releasing chemical fertilizer under growth camber conditions. After 35 days, growth enhancement of WLG was the largest in the mulching sheet treatment together with the inoculum and the fertilizer. In the field experiment, the effect of the mulching sheet was also examined in combination with the inoculum of two different AM fungi by using concrete framed fields. Mulching enhanced both the growth of WLG and fungal colonization in the case of both inocula after a growth period of 95 days. These results supported our previous findings showing that the use of the mulching sheet increased the effect of AM fungal inoculum on the rehabilitation of degraded soils.
