All crops have a maximum salt level they can tolerate without a yield loss.
Salt levels above a crop's maximum tolerance level sharply reduce yields. The generally accepted soil salinity ratings for field crops, pasture and hay grasses and vegetables are shown in Tables 2 through 4, respectively. As shown in Table 1, crops are often more sensitive at germination and early crop growth. Some varieties within each crop are more tolerant to salt than others. Local agronomists and seed suppliers can help select the best varieties.
