Essential Nutrient Solutions for Thriving Hydroponic Tomato Plants
Altering the pH is critical because a slight deviation can lock out essential nutrients, hindering plant growth. We also measure electrical conductivity (EC) to assess the nutrient concentration in our solutions. A precise EC level indicates that our tomatoes are getting the right amount of nutrients without risking toxicity or deficiency.

Inorganic compounds form the majority of the soil solution. Plants access water though the soil. Water is absorbed by the plant root, transports nutrients throughout the plant, and maintains the structure of the plant. Essential elements are indispensable elements for plant growth. They are divided into macronutrients and micronutrients.

Abstract Legumes and cereals contain high amounts of macronutrients and micronutrients but also anti-nutritional factors. Major anti-nutritional factors, which are found in edible crops include saponins, tannins, phytic acid, gossypol, lectins, protease inhibitors, amylase inhibitor, and goitrogens. Anti-nutritional factors combine with nutrients and act …

Iron Nutrition in Plants: Towards a New Paradigm?
Iron (Fe) is an essential micronutrient for plant growth and development. Fe availability affects crops' productivity and the quality of their derived products and thus human nutrition. Fe is poorly available for plant use since it is mostly present in soils in the form of insoluble oxides/hydroxides, especially at neutral to alkaline pH.
Effect of iron nanoparticles and conventional sources of Fe …
High concentrations of soluble salts alter the nutrient acquisition in soils and availability of essential nutrients to plants. The application of Fe in salt-affected soils increased rice yields by maintaining the balance of nutrients in soil and plants (Fig. 4 and Fig. 5). Maximum decrease in SAR was recorded with the application of FeNPs at ...
Interaction Between Macro‐ and Micro-Nutrients in Plants
