Influence of magnetised irrigation water on the fertigation process and potato productivity

Abstract

An experiment was conducted for two seasons on a farm in the Mit Kenana village, Qalyobia, Egypt. The aim was to study the influence of a magnetised water technology on the fertilisers during irrigation (fertigation) and its impact on the water, soil as well as the yield and yield components for potatoes. The experiment included: Normal water (NM), magnetic water (MW), adding fertiliser before (FMW) and after magnetism (MWF). The results indicated that irrigation with magnetised water and then adding fertiliser (MWF) had a positive significant effect on the water and soil properties, the tuber engineering parameters improved and the potato productivity increased by 40.5% higher than the NM method.<br />The fertigation unit has to be installed after the magnetic device because the direct magnetisation of the water with the fertilisers contributes to the cracking and increases the solubility of the fertilisers that may lead to the possibility of leaching some of them away from the roots, which implies losing some of them and, therefore, decreasing the effectiveness of the fertilisers

Impacts of Magnetic Field Treatment on Water Quality for Irrigation, Soil Properties and Maize Yield.

“…The results have shown that MTW changes the distribution of salts between soil layers reducing their content in the upper layers which are more important for agriculture. Magnetic water treatment technologies are needed to reduce the rate of salt accumulation and improve the leaching of salts below the root zones of salt-sensitive agricultural crops and in general in salt-affected soils under arid conditions [24] and [35]. An additional interesting finding of this study, was that the total distribution area and volume of water, soil field capacity and consequently the available water in the investigated sandy soil irrigated with magnetized water was higher than soils irrigated with unmagnetized water.…”

“…The reason that soil moisture was higher for the magnetized irrigation water might be due to that water molecules are released to make the water more cohesive as influenced by hydrogen bonds and Van der Waals forces. Thus, the water molecules were easily attached to soil particles and did not leach to lower depths and also the water molecules easily penetrated into the micro spaces of soil particles and were thus impeded from moving to the lower depths [24] and [35].…”

“…In conclusions, magnetic field treatment of irrigation water can improve fertigation performance in drip irrigation systems. Fertigation of NPK fertilizers using magnetized water compared to unmagnetized water increased the dripper discharge which indicates less dripper clogging and higher distribution uniformity causing increased water and fertilizer use efficiencies and consequently increased maize crop yield per unit of water or fertilizer and quality parameters [24] and [35]. The results showed that the dripper discharge average, distribution uniformity of soil moisture, moisture content in root zone % and accordingly maize crop yield per unit of water or NPK fertilizers required are significantly influenced by type of irrigation water (magnetized and unmagnetized) and drip irrigation distances (100, 200 and 300m) from the magnetic treatment device.…”

“…An additional interesting finding of this study, was that the total distribution area and volume of water, soil field capacity and consequently the available water in the investigated sandy soil irrigated with magnetized water was higher than soils irrigated with unmagnetized water. It could be assumed that saline irrigation water after magnetic treatment has higher capacity to stay in such sandy soil due to reduction of magnetized water surface tension and viscosity [24], [35] and [40]. Results by [40], indicated that magnetic field treatment of water decreased the contact angle of water and increased water ability to enter into soil micropores.…”

Meta-learning Prediction of Physical and Chemical Properties of Magnetized Water and Fertilizer Based on LSTM

“…In modern agriculture, magnetic treatment of water and fertilizer irrigation has been the underlying physical technology to increase crop yields [1]. Some studies have confirmed that irrigation with magnetized water and fertilizer can enhance the ability of some crops to absorb nutrients [1][2][3]，and also improve some specific goals [4][5][6][7][8].In fact, the essence of magnetized water and fertilizer is that under the action of a magnetic field, its physical and chemical properties, such as surface tension coefficient, viscosity, conductivity, PH value, will change [9][10][11], this has an impact on the growth of crops. This article hopes that by predicting the physical and chemical properties of magnetized water and fertilizer(PCPMWF ) , it will further help to explore the impact of magnetized water and fertilizer irrigation on crops.…”
