Table 3. Laboratory Analysis of the Upper Four 

 Inches of Soil for Selected Plant Communities 



In evaluating these data, the following remarks of Sandoval et al. (1973) 

 may be useful: Productive soil have pH values between 6.0 and 8.0. EC values 

 between 2 and 4 are considered slightly saline; 4 to 8 is moderate; 3 to 16 

 is severe. SAR values greater than about 12 indicate potential problems in 

 structural stability and permeability. 



See Dodd et al. (1964) for a discussion of saline soils and plant 

 communities, some of which are similar to the communities mentioned here. 

 Ungar et al. (1969) discusses some plant communities and associated soil 

 characteristics for saline areas in Nebraska. Hayward and Bernstein (1958) 

 reviewed the salt tolerance of many plants.
