IDS Chelated Salts – High-Efficiency Regulators for Plant Growth

IDS chelated salts for plant growth are a new generation of biodegradable chelating agents for agriculture, widely used to enhance plant stress resistance, nutrient uptake, and physiological metabolism. Based on iminodisuccinic acid chelate (IDS) technology, these chelated micronutrients offer excellent stability, bioavailability, and environmental compatibility. Think-Do provides a complete range of IDS chelated micronutrients tailored for modern sustainable agriculture.

I. Enhancing Plant Stress Resistance

1. Improved Drought Resistance

Under drought stress, IDS magnesium chelate plays a critical role in regulating plant water balance. Magnesium chelated with iminodisuccinic acid chelate enhances the accumulation of compatible solutes such as proline within plant cells. Proline, due to its strong hydrophilicity, lowers cellular osmotic potential, allowing plants to maintain water uptake even under severe drought conditions. This mechanism helps preserve cell turgor pressure and normal physiological functions.

Field studies show that wheat sprayed with IDS magnesium chelate drought resistance formulations at the jointing and grain-filling stages exhibited a 10%–15% higher relative leaf water content compared to untreated controls. Additionally, IDS magnesium chelate regulates stomatal conductance, reducing transpiration rates and improving water-use efficiency. By promoting timely stomatal closure during water stress, plants effectively minimize moisture loss, ensuring yield stability in arid environments.

2. Enhanced Cold Tolerance

Low-temperature stress can severely damage plant cell membranes. IDS copper chelate improves membrane stability by activating antioxidant defense systems. Copper, an essential cofactor for numerous enzymes, plays a vital role in oxidative stress regulation.

Under cold stress conditions, IDS copper chelate cold stress tolerance treatments significantly increase the activity of antioxidant enzymes such as superoxide dismutase (SOD) and peroxidase (POD). These enzymes eliminate excessive reactive oxygen species (ROS), including superoxide radicals and hydrogen peroxide, which would otherwise cause lipid peroxidation and membrane damage.

In winter greenhouse vegetable production, root irrigation with IDS copper chelate markedly reduced cold injury symptoms. Plants maintained healthy green foliage and recovered growth more rapidly after low-temperature exposure, demonstrating improved cold resilience.

3. Improved Salt Tolerance

For crops grown in saline or alkaline soils, IDS iron chelate salt stress solutions effectively alleviate ionic toxicity. High sodium concentrations in saline soils disrupt intracellular ion homeostasis. IDS iron chelate promotes the compartmentalization of excess sodium ions into vacuoles, reducing their toxic effects on cytoplasmic enzymes and organelles.

Simultaneously, IDS iron chelate enhances potassium uptake, maintaining a favorable K⁺/Na⁺ ratio essential for metabolic stability. Additionally, IDS iron chelate regulates plant hormone balance by increasing abscisic acid (ABA) levels. ABA promotes stomatal closure, reduces water loss, and activates salt-tolerance-related gene expression.

Field applications in coastal saline soils showed that cotton treated with IDS iron chelate achieved higher germination rates, stronger seedling vigor, and significantly enhanced salt tolerance.

II. Promoting Plant Growth and Development

1. Root Growth Promotion

IDS zinc chelate root development formulations play a key role in stimulating root system growth. Zinc is an essential component of enzymes involved in auxin biosynthesis. IDS zinc chelate ensures efficient zinc uptake, supporting normal auxin production.

Auxin promotes root cell division and elongation, leading to increased root length and density. In ornamental flower cultivation, seed soaking or root irrigation with IDS zinc chelate significantly accelerated root establishment. For example, carnation plants treated with IDS zinc chelate before transplanting developed 30%–40% more lateral roots, resulting in stronger anchorage, enhanced nutrient absorption, and improved overall plant vigor.

2. Enhanced Photosynthesis

IDS manganese chelate photosynthesis enhancement plays a critical role in improving photosynthetic efficiency. Manganese is a key component of the oxygen-evolving complex in photosystem II, directly involved in water splitting and oxygen release.

By supplying readily available manganese, IDS manganese chelate ensures optimal photosystem II function and improves light energy conversion efficiency. Manganese also activates multiple enzymes involved in carbon assimilation.

In fruit tree cultivation, foliar application of IDS manganese chelate increased chlorophyll content by 15%–20% and boosted net photosynthetic rates by 20%–30%. As a result, carbohydrate production increased, leading to improved fruit size, sugar accumulation, coloration, and overall quality.

3. Optimized Nutrient Uptake and Metabolism

IDS molybdenum chelate nitrogen metabolism optimization is essential for efficient nitrogen utilization. Molybdenum is a critical component of nitrate reductase and nitrogenase enzymes, which are vital for nitrate reduction and biological nitrogen fixation.

IDS molybdenum chelate significantly enhances nitrate reductase activity, improving nitrate assimilation and nitrogen-use efficiency. In leguminous crops, IDS molybdenum chelate strengthens root nodule activity and nitrogen fixation by symbiotic bacteria.

Moreover, IDS molybdenum chelate promotes the uptake and utilization of phosphorus and potassium, maintaining overall nutrient balance. In soybean cultivation, application of IDS molybdenum chelate increased plant nitrogen content, enhanced protein synthesis, improved seed filling, and boosted yield by 10%–15%.
