EFFECT OF PHOSPHOGYPSUM, FYM AND SUBSOILING ON SOME SALT AFFECTED SOIL PROPERTIES AND ITS PRODUCTIVITY AT NORTH DELTA
Soil, Water and Environment Research Institute - ARC
Abstract
Field experiment was carried out during the two successive seasons 2000 and 2000/2001 to study the effect of some amelioration processes on some physical and chemical properties and yield productivity of salt affected soil at North Delta. A split-split plot design with four replicates was used. Phosphogypsum (PG) treatment with three levels: zero, 50% and 100% of gypsum requirements was assigned to the main plots. The sub plots were occupied by subsoiling treatment with two levels: without and with subsoiling. Farmyard manure (FYM) treatment with two levels: without and w'th FYM application. Amelioration treatments (organic manure and/or Phosphogypsum) have a significant effect on decreasing bulk density and increasing the aggregation parameters (WSA, opt. size, MWD, AI and SC) in the sequent layers of soil profile especially in the surface layers.
Also, amelioration processes have a highly significant effect on O.M., EC. pH and ESP.
Moreover, amelioration processes had a highly significant effect on sorghum and barley yield. PG has a highly significant effect on the yield of both crops. These results may be attributed to that Phosphogypsum affected the soil properties such as porosity. ESP, pH and nutrients availability, which enhance plant growth. Regarding subsoiling and FYM, it could be noticed that subsoiling and FYM as well have a highly significant effect on both crop yields.
