Irrigation salinity – causes and impacts
www.dpi.nsw.gov.auSalinity is the accumulation of salts (often dominated by sodium chloride) in soil and water to levels that impact on human and natural assets (e.g. plants, animals, aquatic ecosystems, water supplies, agriculture and infrastructure). Irrigation salinity occurs in irrigated landscapes (Figure 1). Primary and secondary salinity
Inherent Factors Affecting Soil EC
www.nrcs.usda.govSalinity Management Soil EC is affected by cropping, irrigation, land use, and application of fertilizer, manure, and compost. When managing for salinity on irrigated land, irrigation water salinity must also be measured. Irrigating in amounts too low to leach salts, or with water high in salts, s salts to accumulate allow in
