Common questions about Hydrated Lime in agro chemicals applications
Bordeaux mixture is a classic copper-based fungicide prepared by combining copper sulphate with hydrated lime. The lime neutralises the acidity of copper sulphate, forming a stable copper-lime complex that is less phytotoxic and provides prolonged antifungal activity on plant surfaces.
Hydrated lime (Ca(OH)₂) is a strong base that rapidly dissolves in water to release hydroxide ions, raising the pH of the formulation system. It is used in controlled quantities to adjust formulation pH into the range required for stability of the active ingredient and optimal performance.
Hydrated lime neutralises soil acidity by reacting with hydrogen ions in the soil, raising pH towards the neutral range (6.5–7.0) optimal for most crop nutrient uptake. It also supplies calcium, improves soil structure, reduces aluminium and manganese toxicity, and creates conditions favourable for beneficial soil microorganisms.
Yes. Hydrated lime (Ca(OH)₂) is much more reactive and faster-acting than agricultural lime (CaCO₃). It raises soil pH more quickly but must be applied at lower rates. CaCO₃ is slower but gentler and preferred for gradual, long-term soil pH management.
By maintaining the required alkaline pH in the formulation, hydrated lime prevents hydrolysis of pH-sensitive active ingredients that would otherwise degrade under acidic conditions. This pH buffering action extends the effective shelf life of the agrochemical product during storage.
For agrochemical use, hydrated lime should have minimum Ca(OH)₂ content of 90–95%, controlled particle size, low heavy metal content (particularly lead and arsenic), and consistent whiteness. Our Micron Lime and Hydrated Lime 2001686 grades meet these agrochemical quality requirements.
