Orthosilicic Acid & Silicon Nutrition

Silicon nutrition is emerging as a critical enabler of sustainable crop productivity. Fenton Chemicals develops orthosilicic acid solutions that integrate into progressive agricultural systems to enhance plant vigor, resilience, and long term yield stability.

Orthosilicic Acid 2% WSL

Orthosilicic Acid Product

Introduction

Fenton Chemicals is pleased to introduce its new innovative product based on highly Stabilized Orthosilicic Acid Liquid at 2% Concentration. Silicon is an essential nutrient for plants and is present in soils, minerals, and ocean water. But this silicon is poorly absorbed and not available for plants uptake. Silicon in the form of orthosilicic acid is the highest bioavailable form of silicon to plants.

ORTHOSILICIC ACID HAS THE FOLLOWING BENEFITS TO PLANTS

  • Stimulates photosynthesis process.
  • Increases uptake of primary and secondary nutrients which results in enhanced crop yields.
  • Reduces water consumption.
  • Enhances resistance to conditions like drought.
  • Improves resistance to bacteria, insects, and fungal diseases.
  • Improves Color, Size, Number, and Quality of Fruits.
  • Increases Plants Growth.
  • Enhances mobilization of nutrients.
  • Reduces consumption of Fertilizers and Pesticides.
  • Increases Grain and Straw yield along with Silicon Content.
  • Increases Leaf Area and Chlorophyll Content.
  • Increases resistance of Plants towards Biotic and Abiotic Stresses.
  • Excellent results in most crops like Rice, Sugarcane, Papaya, Apples, Grapes, Onion, Potatoes, Chilli, Wheat, Sunflower, Corn, tomatoes.

Frequently Asked Questions

What is orthosilicic acid 2 percent WSL and how is it used?
Orthosilicic acid 2 percent WSL is a water soluble liquid formulation containing stabilized plant available silicon at 2 percent concentration. It is used in silicon based fertilizers, foliar nutrition products, and agrochemical formulations to improve crop stress tolerance, cell wall strength, disease resistance, and overall yield.
Is Fenton Chemical India's largest orthosilicic acid manufacturer?
Fenton Chemical is among India's largest manufacturers of orthosilicic acid 2 percent WSL, with dedicated production capacity, stabilized formulations, and export ready supply to serve fertilizer companies and agrochemical formulators globally. Our OSA facility supports high volume domestic and export orders.
How stable is Fenton Chemical's orthosilicic acid 2 percent WSL formulation?
Fenton Chemical's orthosilicic acid is manufactured with proprietary stabilization chemistry to prevent polymerization and maintain plant available silicon content across shelf life. Detailed stability data, storage recommendations, and batch consistency records are available on request for formulation approval.
Does Fenton Chemical offer FCO approved orthosilicic acid for the Indian market?
Yes, Fenton Chemical supports FCO compliance requirements for orthosilicic acid used in fertilizer applications. We provide regulatory documentation, registration support, and Certificate of Analysis with every batch dispatched to fertilizer brands and formulators in India.
What is the minimum order quantity for orthosilicic acid 2 percent WSL?
Minimum order quantity for orthosilicic acid 2 percent WSL from Fenton Chemical is flexible, with options ranging from small trial batches to bulk container loads. Please contact sales@fentonchemical.com for MOQ, pricing, and delivery details based on your specific requirement.
Can Fenton Chemical export orthosilicic acid 2 percent WSL to international markets?
Yes, Fenton Chemical is an established orthosilicic acid exporter India, shipping OSA 2 percent WSL to Asia, Africa, and other international markets with proper export packaging, dangerous goods documentation where applicable, MSDS, and reliable delivery lead times.
Is orthosilicic acid safe to use in agricultural applications?
Yes, orthosilicic acid is widely regarded as safe for agricultural use when applied at recommended dosages. Fenton Chemical's OSA 2 percent WSL is manufactured under ISO 9001:2015 quality standards with documented specifications, and application guidance is provided in the Technical Data Sheet for safe handling and dosing.
How is orthosilicic acid different from regular silica or silicate fertilizers?
Regular silica and silicate fertilizers contain silicon in forms that plants cannot directly absorb until they slowly convert to orthosilicic acid in the soil. Fenton Chemical's OSA 2 percent WSL supplies silicon already in the orthosilicic acid form, making it immediately plant available without relying on slow soil conversion. Suggestions Is orthosilicic acid safe? Is orthosilicic acid the same as silicon dioxide?

Orthosilicic Acid & Silicon Nutrition

Crop nutrition strategies increasingly recognize silicon as a performance-enabling element rather than a supplementary input. Structural integrity, stress resilience, and nutrient efficiency are directly influenced by the availability of plant-absorbable silicon.

Fenton Chemicals develops orthosilicic acid-based silicon nutrition solutions engineered to support modern agricultural programs. Designed for bioavailability and formulation stability, our products integrate effectively into progressive crop nutrition systems across varied agronomic conditions.

Manufactured at our facility in Indore, India, our silicon nutrition solutions are produced under structured quality protocols to ensure reliability at commercial scale. As a speciality chemicals manufacturer in India, we support fertilizer companies and agri-input brands across domestic and export markets with technically grounded, scalable solutions.

Performance Advantages

  • Bioavailable silicon for efficient plant uptake
  • Enhanced structural strength and lodging resistance
  • Support for abiotic stress tolerance
  • Improved nutrient utilization efficiency
  • Consistent batch-to-batch manufacturing reliability
