Lime may occur naturally in some soils but may require addition of
sulfuric acidfor its agricultural benefits to be realized. Gypsumis also used to supply calcium for plant nutrition.
Other forms of lime have common applications in agriculture and gardening, including
dolomitic limeand hydrated lime. Dolomitic lime may be used as a soil input to provide similar effects as agricultural lime, while supplying magnesiumin addition to calcium. In livestock farming, hydrated lime can be used as a disinfectantmeasure, producing a dry and alkalineenvironment in which bacteriado not readily multiply. In horticultural farming it can be used as an insect repellant, without causing harm to the pest or plant.
Spinner style lime spreaders are generally used to spread agricultural lime on fields. Several companies such as
Stoltzfus Spreadersmanufacture spreaders for this purpose.
