In contrast to sulfur addition, peat incorporation produced an immediate reduction in soil pH without increasing soluble salts. It will be very interesting to see what effect the 1995 soil amendments have on soil pH in 1996. I expect to see the natural reaction of the central Ohio soil overcome the effect of sulfur addition, causing the soil pH in the sulfur plots to increase. Soluble salts from the sulfur addition will probably be leached away by rainfall. 0.61 6.7 0.65 6.4 1.00 6.5 Compost treatments are averaged.
All differences are statistically significant.
