Abstract
Two field experiments were carried out in sandy soil at the Ismailia Agricultural Research Station during winter seasons of 2017/2018 – 2018/2019. The aim is to study the effect of magnetized aqueous solutions (0.5% v/v) of potassium fulvate (KF) and/or potassium humate (KH) sprayed in presence of soil applied rock phosphate (RP) and/or super phosphate (SP) fertilizers (16.09 Kg P ha-1 application rate) on faba been (Vicia Faba L.) plant. Spraying of solutions was applied four times 30, 50, 70 and 90 days after sowing. Control treatments (0 additions), magnetized (KFM and/or KHM) and non-magnetized (mixed with tab water, KFT and/or KHT) treatments were distributed in a complete randomized block design. Cultivation was performed as recommended by the Ministry of Agriculture. At maturity stage and after harvest, yield (Mg ha-1) and some yield components, percentage (%) of N, P, and K available in soil and total in plant, pH and EC were estimated. Results showed the magnetic treatments KFM and KHM resulted in the most significant increase of the available P (mg kg-1) in soil for RP and SP treatments and the available N for RP. The increase in the available K in soil was non-significant. Magnetic solutions of KFM and KHM also exhibited a significant increase in the seed weight and dry weight of pods (g plant-1) but the increase in the yield of seeds and straw (Mg ha-1) was non-significant. Foliar application of magnetic fulvate and humate solutions may enhance the efficiency of phosphorus fertilization under sandy soil conditions.
