The Effects of Soil and Water Salinity in Crop Production<br />

Salinity and Sodicity in New<br />

Mexico and Texas Soils<br />

• Concern on soils with salinity and sodicity<br />

levels high enough to affect production<br />

• Soils with high amounts of soluble salts are<br />

called saline soils (exhibit whitish surface<br />

crust when dry—Na2SO4; NaCl; CaCO3—from 3 types of salts: SO4, CO3, and Cl)<br />

• Soils high in sodium (sodic sodic soils) soils may present<br />

physical restrictions to plant growth from high<br />

amounts of sodium, Na + )<br />
