CN AGRO
PSB Bio-fertilizer · Soil Rejuvenation
AGN
Puts the microbial population back into a soil that intensive cropping has stripped, so nutrients already in the ground start becoming available again.
Home/Products
Six formulations. One system.
Soil improvement, the rhizosphere, natural fertilization, plant defence and water management — used alone or assembled into a programme around what a particular soil and crop actually lack.

What is your soil short of?
Select one outcome or several. Choosing more than one narrows the range to products that deliver all of them.
Biostimulant · 100% Natural Soil Conditioner
Fulvic 25
Fulvic and humic substances that chelate trace elements, hold water in the soil and switch on the plant's own stress-response enzymes.
Biostimulant · 100% Natural Bioflavonoid
Crop4Life Biofoliar
Flavonoids from bitter orange, taken in through the leaf, prompting the plant to make more of its own — and changing how it uses everything it is fed.
Natural CO₂ Organic Foliar Spray
Nature's Green 4+
Nano-ground limestone that penetrates the leaf and releases CO₂ inside the cell, lifting photosynthesis without touching the soil.
Biostimulant · All-Natural Protective Plant Wash
Plant Armor Elite
A natural-polymer film over the plant surface that clears and prevents surface pests and disease — and needs no wash-off before harvest.
Root Zone Moisture Management
Hydretain
Hygroscopic and humectant components that pull moisture out of the root zone air and hold it where roots can reach — no polymer, no wetting agent.

Before you spray
Getting a bio-input to behave.
Hard, alkaline or heavily chlorinated spray water will strip the value out of a biological input before it reaches the leaf. Check pH and hardness once at the start of the season; correcting the water is usually cheaper than doubling the rate.
Fill to half, start agitation, then add powders before liquids and biologicals last. Never pour a concentrate into a dry or still tank. If you are combining products for the first time, run a jar test with the same water at the same ratio and leave it 30 minutes.
Leaf uptake happens while stomata are open and the droplet is still wet. Early morning or evening, on a dry canopy, with enough volume to wet the leaf without run-off.
Store packs closed, in shade, off the floor. Use a bio-fertilizer within the season it was bought, and do not leave a diluted tank standing overnight.
Foliar biostimulants show up in weeks. Soil biology moves slower — structure, organic matter and microbial population change over a full crop cycle. Leave an untreated strip so you have something honest to compare against.
Get in touch
Two ways to start.
You grow the crop
Tell us the crop, the acreage and what the soil has been giving you. We come back with a programme built around it — and, where we can reach you, an agronomist in the field.

CN Agro reaches farmers through people who already have their trust. If you run a krishi seva kendra, an input shop or a distribution business, there is territory open.
