The reclamation of new territories which are limited in energy and materials needs resource- and energy-saving techniques. One of such technique is the processing of water and artificial fertilizer solutions in a magnetic field. The aim of this research is to work out the impact of a magnetic field on water and solutions of artificial fertilizer and to find out the most effective way to process. The authors have figured out that a magnetic field enhances the speed of chemical reactions, the solvability of salts and fertilizers, and increases the concentration of oxygen in a water solution. The most effective processing of water solutions in magnetic field is when magnetic induction is 0,065 Тl, a four-time back magnetization takes place, and the velocity of a solution is 0.4 m/s. These parameters of the processing increase crop yield by 15-20%, decrease the consumption of artificial fertilizer by 10-15%, and enhances the product quality.

The reclamation of new areas and distant lands with limited energy and material resources demands using resource- and energy-saving technologies. One of such technologies can be magnetic treatment of irrigating water and artificial manure solutions, and presowing treatment of seeds of agricultural crops in magnetic field. The authors found that magnetic field accelerates the velocity of chemical reactions, enhances salts and fertilizers solvability, and increases oxygen concentration in a solution. Magnetic field improves membrane cells permeability which accelerates molecules and ions diffusion through it. This process improves the ability of a seed to absorb water and increases the concentration of oxygen in a cell. Presowing treatment of seeds increases their ability of germination by 26–50%, sprouting by 20–30%. The best regime of water solutions and seeds of agricultural crops treatment in magnetic field is when magnetic induction is 0.065 Tl and the velocity of a solution is 0.4 m/s.

While irrigated crops produce much higher yields than rain-fed crops, the ionic components of irrigation water have important effects on crop yield. Groundwater is widely used for irrigation in the Baojixia irrigation area in China. The chemical characteristics and water quality of groundwater in the Baojixia irrigation area were analyzed and evaluated to study the impact of groundwater quality on crop yield. Results showed cations in the groundwater to mainly be Na+, Ca2+, and Mg2+, whereas the anions are mainly HCO3−, SO42−, and Cl−. Water-rock interaction and cation exchange were identified as the main factors affecting hydrogeochemical properties from west to east. The study found salinity and alkalinity of groundwater in the western region of the study area to be low, and therefore suitable for irrigation. Groundwater in the eastern part of the study area was found to have a medium to high salinity and alkalinity, and is therefore not recommended for long-term irrigation. The groundwater irrigated cultivation of wheat and corn in the research area over 2019, for example, would have resulted in a drop in the annual crop output and an economic loss of 0.489 tons and 0.741 × 104 yuan, respectively. Irrigation using groundwater was calculated to result in the cumulative loss of crop yields and an economic loss of 49.17 tons and 80.781 × 104 yuan, respectively, by 2119. Deterioration of groundwater quality will reduce crop yields. It is recommended that crop yields in the study area be increased by strengthening irrigation water management and improving groundwater quality.

Our study area in the People's Victory Canal Irrigation District of Henan Province in China has been transferring agricultural water to the city for municipal use. This study starts with an examination of the impacts of irrigation frequency, irrigation water sources, and irrigation water supply performance on crop yield and net crop revenue, using data from a survey of 182 households in the study area. Thereafter, it analyzes the impact of agricultural water reallocation (AWR) on crop yield and revenue. The study ends with an estimation of the compensation for affected farmers and a discussion of the compensation methods. Regression results indicate that irrigation frequency shows a significantly positive impact on crop yield and net crop revenue. The change of irrigation water source from canal water to well water and local small river water decreases the integrated crop yield of wheat and rice by 9% and 12%, and decreases the net integrated crop revenue by 16% and 19%, respectively. AWR decreases the integrated crop yield of wheat and rice by at least 2%, and decreases the net integrated crop revenue by at least 3.5%. Estimated compensation for affected farmers is between 78.72 and 97.85 USD/ha.

Abstract: Nanomaterials are widely used in all walks of life, bringing great changes to our life and production. In addition, nanomaterials have also been used in agriculture. The most common ones are carbon-based nanomaterials and TiO2 nanoparticles, which can stimulate plant growth and increase crop yield. However, not all nanomaterials have a positive effect on plant growth. Therefore, it is necessary to understand the influence of nanomaterials on plants after entering the environment. Nanomaterials can be inhaled directly or through endocytosis. Some nanomaterials will become the corresponding ion state to enter the plant, while some larger nanomaterials will block cell wall channels or adsorb on the surface of plants. Nanoparticles (NPs) enter the plant can produce positive or negative effects on the plant's genes, proteins. This paper discusses the impact of nanomaterials on plant growth and the molecular level.

The reclamation of new areas or distant lands, which have limited energy and material resources, requires the use of energy saving technologies, which include presowing processing of seeds in magnetic field. The aim of this chapter is to reveal the effect that magnetic field has on seeds and to detect the most effective condition to process seeds in magnetic field before sowing and constructive parameters of the equipment. Magnetic field accelerates chemical reactions, which occur in plant cells, salts and fertilizers dissolve better, and the permeability of cell membranes increases, which accelerates the diffusion of molecules and ions. Due to this, the concentration of ions and oxygen molecules in a cell increases and seeds absorb water better. Presowing processing of seeds stimulate 25–40% seedling emergence and 30–35% germination. The most effective condition of presowing processing of seeds in magnetic field is 0.065 Тl magnetic induction with four times magnetic reversal and 0.4 m/s seed velocity. As a result, agricultural crop yield increases approximately by 20–25%.

Rice and wheat are major cereal crops in Nepal. Climate change impacts are widespread and farmers in developing countries like Nepal are among the most vulnerable. A study was carried out to assess the impact of climate change on yield and irrigation water requirement of these cereal crops in Bhaktapur, Nepal. Laboratory and soil-plant-air-water analysis showed silt-loam being the most dominant soil type in the study area. A yield simulation model, AquaCrop, was able to simulate the crop yield with reasonable accuracy. Future (2030–2060) crop yield simulations, on forcing the Providing Regional Climates for Impacts Studies (PRECIS) based on regional circulation model simulation indicated decreased (based on HadCM3Q0 projection) and increased (based on ECHAM5 projection) yield of monsoon rice for A1B scenario, and rather stable yield (for both projection) of winter wheat. Simulation results for management strategies indicated that the crop yield was mainly constrained by water scarcity and fertility stress emphasizing the need for proper water management and fertilizer application. Similarly, a proper deficit irrigation strategy was found to be suitable to stabilize the wheat yield in the dry season. Furthermore, an increase in fertilizer application dose was more effective in fully irrigated conditions than in rainfed conditions.

Application of low quality water for irrigation is compulsive in facing water scarcity. Use of a magnetic field is an approach to overcome this challenge. This study examined the impact of magnetic field technology on improving germination under water of different salinity levels. An experiment was conducted to determine the effects of saline water levels, i.e. (S1):0.5, (S2):2, (S3):4 and (S4):6 dS/m combined with magnetized technology (with or without) on maize growth. Thus, magnetic treatment was applied by passing the irrigation water through a 1,500 mT magnetic field at 3 litres per minute (lpm) flow rate. Some emergence indices, such as emergence index, emergence rate index (ERI) and mean emergence time, were used to evaluate the germination of maize seed. As for soil properties after plant harvest, the use of magnetically treated irrigation water reduced soil pH but increased soil electrical conductivity and available N and P. ERI increased from 7.6 to 10.2, 9.1 to 11.1, 10.3 to 13.3, and 11.8 to 13.3 when applying the magnetized field for S1, S2, S3 and S4, respectively. Overall, the growth parameters of maize were improved by using magnetic technology with saline water, while the opposite trend was shown for increasing salinity without magnetic treatment.

In this paper, polymer composites based on polylactide (PLA) and epoxy resin (Epidian 5) were studied in terms of the influence of magnetic induction on their changes in physicochemical properties. The composites contained admixtures in the form of magnetite (Fe3O4) and crystalline cellulose (Avicel PH-1010) in the amount of 10%, 20%, and 30% by weight and starch in the amount of 10%. The admixtures of cellulose and starch were intended to result in the composites becoming biodegradable biopolymers to some extent. Changes in physical and chemical properties due to the impact of a constant magnetic field with a magnetic induction value B = 0.5 T were observed. The changes were observed during tests of tensile strength, bending, impact strength, water absorbency, frost resistance, chemical resistance to acids and bases, as well as through SEM microscopy and with studies of the composition of the composites that use the EDS method and of their structure with the XRD method. Based on the obtained results, it was found that the magnetic induction value changes the properties of composites. This therefore acts as one method of receiving new alternative materials, the degradation of which in the environment would take far less time.

Magneto Rheological Elastomers (MREs) are composite materials based on an elastomer filled by magnetic particles. Anisotropic MRE can be easily manufactured by curing the material under homogeneous magnetic field which creates column of particles. The magnetic and elastic properties are actually coupled making these MREs suitable for energy conversion. From these remarkable properties, an energy harvesting device is considered through the application of a DC bias magnetic induction on two MREs as a metal piece is applying an AC shear strain on them. Such strain therefore changes the permeabilities of the elastomers, hence generating an AC magnetic induction which can be converted into AC electrical signal with the help of a coil. The device is simulated with a Finite Element Method software to examine the effect of the MRE parameters, the DC bias magnetic induction and applied shear strain (amplitude and frequency) on the resulting electrical signal.
