Abstract
The main objective of this study is the assessment of some methods for improving the fertility of calcareous soils in Nubaria area
Three field experiments were conducted at Nubaria
Agricultural Research Station Farm -North Tahreer- during
1998/1999 and 1999/2000 growing seasons to study the effect of seed inoculation with phosphate dissolving bacteria "PDB" (under a trade name ofPHOSPHORINE) with or without adding mineral P fertilizer to the biological yields and dry weights of wheat (Triticum aestivum L., var. Sakha 8), maize (Zea mays L., var. Single Cross 10) and soybean (Glycin mf!! L., cv. Craw ford).
Two laboratory experiments were also conducted. One assesses NH3 volatilization using ammonium sulphate (AS), ammonium nitrate (AN) and urea (U) under field capacity and low moisture levels using broadcast (Br), mixing (Mx) and
banding (Bd) techniques. The other assesses the effect of amendments on crust formation, bulk density, total porosity and water holding capacity of calcareous soil.
