Gypsum , also know as calcium sulfate , is unremarkably used to serve lawns in addition to fertilizer . When applied to contract soils , specially those with high clay capacity , gypsum serves to yield the humus by conk out up and loosening soil structure . Nontoxic and safe to deal , gypsum is not a magic bullet to lawn repair , but part of a multitiered lawn vitalisation process that can take age to show termination .
Gypsum Uses
A balmy mineral , gypsum occurs in nature in a lechatelierite sort and observe in large masses call selenite or satin spar . deposit are find in shale beds and are formed as a by-product of sulfide oxidization . The mineral is mined all over the earth with large domestic depositary found in New York , Michigan , Indiana , Texas and California . Well utilize by the manufacturing sector , gypsum is the primary textile used in trash , plaster of Paris , plaster , Sheetrock and as an additive in medicines , bean curd and a clean shape of key called gesso . The vast majority of gypsum is used as a fertilizer or a lawn amendment .
Gypsum Benefits
The Western Farm Press report that the benefit of gypsum are numerous . As a fertilizer , it provides both calcium and S , two of the 16 nutrients essential for lawns and plant . Dr. Brent Rouppet , an husbandry advisor and proponent of gypsum diligence , note that use of gypsum improves soil body structure in compacted solids by merge guts , silt , clay and humus particles together improving atmosphere trend . The mineral helps replace harmful salts prejudicious to lawn growth , reduces water run off and dirt crust all of which allow for preservation in irrigation price . An inexpensive material , gypsum is natural , constitutive and convenient to employ .
Application
Gypsum does not contain any plant nutrients so it can be put on during the fertilization process and will not cause incinerate . program is best achieved using either a drop broadcaster or a broadcast spreader . The recognized pace of practical program is 40 pounds per thousand feet . Backyard gardener should use a mealy form of the mineral .

Argument Against Gypsum
The Agriculture Center at Louisiana State University contends that the software program of gypsum on most grease found in the United States has little consequence due in part to the common mixed bag of native and non - native subsoils . Gypsum has little effect on layered soils that are already open and uncompacted . The exceptions to this are the arid areas of the westerly United States and coastal areas where sodium in the soil incline to be high . As an alternative to gypsum , the LSU Agriculture center suggests core aerify in the leap and summer to reduce grunge compaction .
