Add sulphur to soil (alongside planting/seeding)
A randomized, controlled study in 1994–1996 in an arable field near Aberdeen, UK (Lawson et al. 2004) found that the addition of sulphur to arable soil increased the survival of heather Calluna vulgaris seedlings after six months, but after two years almost all seedlings had died. In plots where sulphur was added survival of heather seedlings (26% survival) was higher than in plots where no sulphur was added (12% survival). After two years survival in plots where sulphur had been added (2% survival) was higher than in plots where no sulphur was added (0% survival). Sulphur was applied in eight 2.6 m x 2.6 m plots, while in eight other plots sulphur was not applied. All plots were sprayed with glyphosate to kill weeds in May 1995. One hundred seedlings were planted in each plot and survival was recorded after six, 12 and 22 months.
