For clay soils, a general application rate is about 40 to 50 pounds of gypsum per 1,000 square feet. Again, it's important to conduct a soil test for more accurate recommendations. How much gypsum do I add per acre? A rough estimate is to apply 1 to 2 tons (2,000 to 4,000 pounds) of gypsum per acre for soil amendment.

The net C sequestration rates of combined incorporated lime and gypsum applications ranged from 0.10 to 0.26 Mg ha −1 year −1, whereas combined surface lime and gypsum applications were higher and ranged from 0.24 to 0.35 Mg ha −1 year −1. Therefore, the results of the present study support the conclusion that, along with …

NWGR's Gypsum Waste Recycling System is capable of processing an average of 25 tonnes of wet or dry drywall per hour and requires just a 745sqm (8,000sq ft) footprint for setup. Requires 480sqm (5,200sq ft) of space for the unit plus an operating area and a coverered storage area for processed material. 12m wide by 40m long by 7.5m high.

Gypsum application rates ranged from 2.2 Mg ha −1 in Indiana to 20 Mg ha −1 in Ohio and Alabama. These rates are 2 to 10 times higher than typically recommended. The length of time from gypsum application to sampling was 4 mo in Wisconsin, 5 and 18 mo in Ohio, 6 mo in Indiana, and 11 mo in Alabama.

1. Introduction. Titanium gypsum (TG) is a industrial gypsum produced during the manufacture of titanium dioxide (TiO 2) by the sulphuric acid process, after neutralisation of the acid waste solution with lime or calcium carbide slag (Zapata-Carbonell et al., 2019, Zhai et al., 2020).At present, every 1 ton of TiO 2 produced in China …
