Effect of magnetic saline irrigation water and soil amendments on growth and productivity of Kalamata olive cultivar

Abstract

he field experiment was conducted at Al-Salam International for Development and Agricultural Investment private farm at 64 Kilometer (Cairo-Alexandria Desert Road), Egypt to study the effect of magnetic saline irrigation water (MW) and soil amendments; magnetic iron (MI) and Nile fertile (NF); on vegetative growth, fruit characteristics, nutrients statues in leaves, fruits and some soil properties, besides proline content in the leaves and fruits of Kalamata olive trees under soil salinity of 3430 ppm and water salinity of 3904 ppm

Improvement of Hyany Date Palms Production as Affected by Magnetite Soil Application and Magnetic Water at South Sinai

“…The best treatment resulted in a pH drop of around 40% and a rise in CEC of about 20% when 750 gm/tree magnetic iron was combined with magnetic water. This result agreement with Mohammed (2013), Fanous et al (2017), Zlotopolski (2017), Abo Gabien et al (2020) and Mohamed and Sherif (2020). According to Fanous et al (2017), this outcome is caused by an increase in the magnetic field's impact on soil organic matter, which releases considerably more organic acids into the rhizosphere.…”

“…Also, the increase in yield due to use the Magnetite treatments as a soil application can be attributed to promote soil structure, capability for exchanging cations, organic matter, Water characteristics and how they impact the growth of plants (Abo-Gabien et al, 2020 andSherif 2020). These outcomes matched those that were shown by (Abobatta, 2015) at Valencia orange trees, (Mohamed, 2017) and (Abdalla, et .al, 2022) on Mango trees.…”

“…The removal of excessive amounts of soluble salts, the lowering of pH levels, and the dissolution of slightly soluble substances like phosphates, sulfates, and carbonates are the three most notable effects of MW in soil. Mohamed and Sherif (2020).…”

“…Additionally, the magnetic device isolates wholly harmful gases like chlorine of the soil, which increases salt growth and nutrient dissolvability. Abo-Gabien et al, (2020) and Mohamed and Sherif (2020).…”

Citrullus lanatus plant response to irrigation water magnetized in sandy soil

“…Likewise the increase in the soil content of P, Cl, and Ca by the moral effect of irrigation as a result of contributing to the liberation of elements from soil granules and the analysis of the organic matter, which was explained by the difference between the estimation of organic matter at the beginning and end of the experiment, which was estimated at 3.81%, then it became 1.5% in the treatment of non-magnetized water and 1% in the treatment of magnetized water. It is worth noting that magnetized water has a higher effect (Table 1), and this is a result of changing the properties of water by magnetic treatment, especially surface tension and solubility (Mohamed and Sherif, 2020).…”
