Application of Filter Mud with Potassium and Magnesium Fertilizers to Improve Sandy Soil Properties and its Productivity of Faba Bean Plant

The experiments were established to study the effect of filter mud with K and Mg fertilizers on physical and chemical properties of sandy soil and its productivity of faba bean plant (Vicia faba L., c.v. 843).A split-split plot design with three replicates was applied.The obtained results showed, the filter mud levels at the same K and Mg levels improved soil physical and chemical properties.There are noticeable increases in total porosity, fine capillary pores, water holding pores, available water (AV), EC, organic matter (OM), penetration resistance (PR) and soil available N, P, K and Mg.On the contrary, there was a decrease in soil pH, bulk density, hydraulic conductivity and quickly drainable pores as compared with the control.The best combined treatment for the parameters under study was at rate of 20 Mgha -1 (FM2) with 119 kgha -1 for potassium (PF2) and magnesium (MF1).Addition of filter mud integrated with potassium and magnesium fertilizers, led to an increase in all yield parameters of faba bean i.e. total yield, seeds yield and straw yield (kgfed -1 ) as compared to the control.These results can be recommended that, using filter mud at rate of 20 Mgha -1 (FM2) with K and Mg fertilizers leads to improve the physiochemical properties of sandy soils and plant productivity which reduces the used of mineral fertilizers.
