Construction drywall as a soil amendment
Article Abstract:
A research conducted to study the effect of construction of dry wall waste in agriculture showed that it increased the fertility of land. The concentration of metals such as cadmium, lead and mercury was less in dry wall waste, with an increase in the concentration of calcium, magnesium and sulphates. The quality of soil improved, increasing the production of grain corn by 25 percent in 1990. The research carried out in a cornfield near Tully, New York shows the benefits of using pulverized dry wall for improving the nutritional status and fertility of the land.

Cropland utilization of ground drywall
Article Abstract:
The use of ground scrap drywall in agricultural lands improves crop production and saves valuable landfill space. A study at the Ohio State University shows that drywall is a good source of nutrients, calcium, magnesium and sulfur. It functions as a soil conditioner and also increases grain yield and test weights. Municipal or ordinary landfills do not accept drywall due to certain problems. Under high temperature and anaerobic conditions of the landfills, bacteria attack the sulphate of gypsum and generate hydrogen sulphide at concentrations toxic to humans.

Reclaiming acid mine soil with drywall and manure
Article Abstract:
Strip mining can lead to problems of soil acidity, and this problem can be tackled by adding organic matter to the soil. A large amount of new construction drywall waste is generated on Ohio. This scrap is mostly comprised of gypsum, with some reinforcing glass fibers, glue and paper backing. The usage of this drywall as a way of restoring acid mine soil has been investigated, and the project has been successful in improving the mine soil for germinating corn and rye.
