| Abstract | ||||
| The major goal of this study was to evaluate the impact of organic fertilizer (i.e town refuse, biogas and FYM) combined with bio-fertilizer (effective microorganism [EM] and the N2 fixer Compomax [CoM] on improveing some physical and chemical properties of sandy soil as well as productivity of faba bean –maize cropping rotation, an alternative cropping system under sprinkler irrigation system. Two field experiment were conducted at the experimental Farm of the Agricultural Research Station, EL-Ismailia Governorate,Agric. Res. Centre (ARC), Egypt, during two winter seasons 2014/2015 and 2015/2016 and two summer seasons 2015 and 2016. A split plot design with three replicates was employed applied treatments, included control mineral fertilizer (recommended dose of N, P & K) (Conventional Agricultural) , organic fertilizer town refuse; biogas manure and farmyard manure [FYM] each applied alone and\or combined with bio-fertilizers i.e EM and the N2 fixer Compomax [CoM] . The obtained results can be summarized as follows: Application of Biogas manure combined with EM recorded the highest yield parameters followed by FYM application and the lowest one was recorded with that received town refuse, likewise the highest available of NPK . Similar trend of available of NPK was also observed with the residual crop (maize). Application of the tested organic fertilizer improved the physical and chemical properties of used soil,[ increasing total porosity (T.P), fine capillary pores (FCP), soil moisture contents at field capacity (F.C), wilting point (W.P), available water (A.W). ECe, O.M, and available N, P and K. On the contrary, pH, bulk density (B.D), hydraulic conductivity (H.C)], as compared with the control. | ||||
