 | Irrigation of Pastures with Gypsiferous Mine Water |
Expanded Title: | Problems associated with the disposal of mine waste water and the shortage of irrigation water created an opportunity. Various studies using mine water for irrigation have been conducted. Soil appears to act as an effective salt sink, through precipitation of salts. Long term studies showed an increase in soil salinity with time although unacceptable levels of salinity in soil are not expected. Various agronomic crops have been researched under these conditions, but very few pasture crops. Economic returns from pastures, usually a cheap food source, are primarily a function of the production of the animals grazing these pastures and the costs associated with irrigation and fertilization. |
