USGA Summary Points:Subsoil sodicity (SAR) ranges from ~7 to 12 across treatments. SAR has increased to the greatest extent (SAR = 12) with no gypsum regimes, although only a slight decrease can be seen due to the 10 lbs./ 1000 sq. ft./ month application. The single spring application of 100 lbs. gypsum/ 1000 sq. ft. has been the most effective treatment at reducing subsoil sodicity in all cases (SAR = 7-8). Addition of monthly wetting agent applications did not noticeably enhance gypsum efficacy on reducing SAR of subsoil (Fig. 1) Water Droplet Penetration Times obtained at the 0.5" depth of 4" and 8" sand caps indicated no hydrophobicity within either sand cap treatment where wetting agent treatments are being applied. In the absence of wetting agents, moderate hydrophobicity is being noted at the surface of the 8" capping depth, likely due to the greater extent of drying following irrigation/rainfall relative to the 4" sand cap (Fig. 2). Surface infiltration rate measurements range from 2.4 to 2.9 mm/ second across the various secondary cultural management treatments, with slightly lower infiltration rates noted for the 4" relative to 8" sand cap. No significant treatment differences due to secondary cultural practices are occurring at the end of the initial season of testing.
