Soils will be analyzed for pH, salinity, texture <br />and sodium adsorption ratio (SAR). <br />Refer to Table 14-7 page 2/2 for location of area represented by each soil sample. <br />Soil sample boundaries were determined by giving each sample equal influence. Thus, <br />the boundary between poor and good quality soil would be located one half way between <br />the two soil sample sites. <br />• <br />4/01 <br />
