Zinc for Human Health: From Soil to Feed to Food, the Zinc Sulfate Value Chain
Published on: 2026-07-28 | Author: Niraj Kedia, Managing Director | Read time: 6 min read
Zinc is essential for human health. It supports immune function, wound healing, growth and the sense of taste and smell. What many people do not realize is that the zinc in our food often traces back to zinc sulfate (zinc sulphate) applied to soil and added to animal feed. This article explains that value chain and where a manufacturer like Chakradhar Chemicals fits, as an upstream supplier of agricultural and feed grade zinc sulfate.
Note: Chakradhar Chemicals manufactures zinc sulfate for agriculture and animal feed use. We do not sell human supplements. This article is educational, to explain how the zinc supply chain connects to human nutrition.
Why the Body Needs Zinc
Zinc is involved in more than 300 enzymes and is central to immunity, cell growth, DNA synthesis and healing. The body does not store much zinc, so a steady dietary intake matters. Zinc shortage is a recognized public health concern in many parts of the world, which is why food systems work to keep zinc in the chain.
From Soil to Plate
Crops can only deliver the zinc that is available in the soil. When soils are zinc deficient, the grains, vegetables and forage grown on them carry less zinc, and that shortfall passes up the chain to animals and people. The links look like this:
- Soil: zinc sulfate corrects deficient soils so crops can take up zinc.
- Crops: better zinc nutrition raises the zinc content of grain and produce.
- Animal feed: zinc sulfate in feed and premix keeps livestock healthy and supports zinc in meat, milk and eggs.
- Food: the zinc in what we eat reflects the zinc that entered the chain upstream.
Agronomic Biofortification
Adding zinc to soil and foliar programs to raise the zinc content of edible crops is known as agronomic biofortification. It is one practical lever to improve dietary zinc at scale, and zinc sulfate is the workhorse input that makes it possible because it is concentrated, affordable and effective.
Where a Zinc Sulfate Manufacturer Fits
A reliable zinc sulfate manufacturer sits at the start of this chain, supplying the agricultural and feed grade zinc that ultimately supports human nutrition downstream. Chakradhar Chemicals has produced zinc sulfate since 1990 in an ISO certified plant, serving agriculture and animal feed buyers who keep zinc moving through the food system.

Chakradhar Chemicals has manufactured zinc sulfate since 1990 with 30,000 plus MTPA capacity and an ISO certified plant.
Frequently Asked Questions
Does Chakradhar Chemicals sell zinc supplements for people? No. We manufacture zinc sulfate for agriculture and animal feed. We are an upstream supplier in the food chain, not a consumer supplement brand.
How does zinc sulfate in farming affect human health? By correcting zinc deficient soils and feed, zinc sulfate helps raise the zinc content of crops, meat, milk and eggs, which supports dietary zinc intake for people.
What is agronomic biofortification? It is the practice of applying zinc (and other nutrients) to crops to increase the nutrient content of the harvested food, a practical way to improve dietary zinc at scale.
