What is PROM?

Rock Phosphate Meets
Organic Power

Phosphate Rich Organic Manure (PROM) is produced by co-composting high-grade rock phosphate with organic matter — typically farm biomass, compost, or manure. During composting, beneficial microorganisms solubilize the rock phosphate, making its phosphorus bioavailable to plants.

The result is a product that delivers far more available phosphorus than plain organic manure, while releasing it slowly over months — feeding roots, flowers, and fruit continuously without risk of burn or leaching.

The Science

How PROM Works
in Your Soil

Three mechanisms work together for outstanding plant results.

🔓

Phosphorus Solubilization

Phosphate-solubilizing bacteria in PROM continuously break down rock phosphate compounds, converting locked phosphorus into plant-available orthophosphate — making every gram count.

🌐

Root Zone Activation

As PROM breaks down in soil, it creates a phosphorus-rich zone directly around plant roots. Roots grow towards this zone, developing a denser, more extensive network for superior nutrient uptake.

🌸

Flowering & Fruiting Trigger

Phosphorus is the key signal for plants to transition from vegetative growth to reproductive growth. High available phosphorus from PROM triggers earlier, more abundant flowering and improves fruit set dramatically.

Why PROM

The Phosphorus Powerhouse
for Every Garden

More phosphorus, more roots, more flowers, more yield — naturally.

🌱

Explosive Root Development

High available phosphorus directly drives root cell division — creating dense, deep root networks that anchor plants and dramatically improve nutrient and water uptake.

🌸

Maximum Flowering

Phosphorus is the primary trigger for bud initiation. PROM's sustained high-P release means more buds, earlier flowering, and extended bloom periods season after season.

🍅

Higher Fruit Yield

Improved phosphorus supply at flowering time increases fruit set rate significantly — more flowers that set into fruit, more fruit that reaches full size.

🔬

Builds Soil Biology

Organic matter in PROM feeds soil microbes, improving overall soil health and nutrient cycling — benefits that compound with every application over seasons.

Application Guide

How to Apply PROM

Apply at planting for best root establishment, or top dress to boost flowering.

1

Measure

Use 50–100g per medium pot at planting, or 150–200g per sq. metre in garden beds and farm rows.

2

Incorporate into Soil

Mix PROM into the root zone — ideally the planting hole or the top 10 cm of soil — for direct root contact and maximum phosphorus uptake.

3

Water Thoroughly

Water well to activate microbial solubilization. PROM begins releasing phosphorus within days and continues feeding roots for 3–5 months.

💡 Pro Tip: Apply PROM 2–3 weeks before the expected flowering period for maximum bloom impact. Combine with Biya Organics Vermicompost for a complete NPK package — PROM covers phosphorus while vermicompost provides nitrogen, potassium, and micronutrients.

Customer Stories

Real Results, Happy Gardens

★★★★★

"My rose plants never bloomed so heavily. After applying PROM two weeks before the flowering season, I had almost double the number of buds compared to previous years. Incredible product."

"Used PROM for my chilli and tomato farm. Root development improved visibly after the first application. Yield this season was 30% higher than last year. I'm making it a permanent part of my routine."

★★★★★

"I was spending a lot on chemical phosphate fertilizers. Switched to PROM and the results are just as good — actually better because the release is gradual and my plants aren't getting stressed. And it's organic!"

FAQ

Frequently Asked Questions

Our PROM contains 12% or more available phosphorus (P₂O₅), which is significantly higher than standard organic manures which typically contain 1–3% phosphorus. This is achieved through co-composting with high-grade rock phosphate and microbial solubilization.
Regular organic manure has a low phosphorus content (1–3%) and provides it slowly. Bone meal has higher phosphorus (~15%) but no organic matter benefits. PROM combines rock phosphate (high P source) with organic matter — giving you high available phosphorus plus the soil-building benefits of organic matter, with microbial activation for sustained release.
Yes — PROM is recognised as an approved input for organic farming under Indian organic standards. It contains no synthetic chemicals and is produced through natural composting processes. It is safe for all organic certification programs.
Yes — PROM works excellently alongside nitrogen-rich organics like vermicompost, neem cake, or organic manure. Combining PROM with vermicompost gives your plants a complete and balanced NPK profile entirely from organic sources.
For maximum flowering impact, apply PROM 2–3 weeks before the expected start of the flowering period. This gives the phosphate-solubilizing microbes time to build up phosphorus availability in the root zone just as the plant begins initiating flower buds.
