VAN Engineering.
This page lists what VAN can change in a formulation, and how far each one can be changed.
016 axes of customization
The questions we will ask you first.
A blend that is right for cotton on a canal-irrigated sandy loam is wrong for the same crop on a saline block under tube-well water.
| Axis | What it decides |
|---|---|
| Crop | Nutrient ratio and form matched to the species and the variety’s demand curve. |
| Soil | pH, calcareousness, organic matter, texture and the fixation behaviour they cause. |
| Growth stage | Germination, early growth, mid-life, reproductive, maturity, each takes a different product. |
| Coating | Release control and deficiency correction built onto the granule rather than blended beside it. |
| Stress | Moderate through severe. Heat at grain fill and cold nights in storage are both formulation problems. |
| Water and delivery | Canal, tube well or hybrid; and increasingly drip, pivot and drone, which dictate solubility and salt index. |
02What VAN can formulate
What can actually be varied, and how far.
Ranges below describe VAN’s commercially practised capability; anything outside them becomes a development question rather than an order.
| Parameter | Range VAN works in | Notes |
|---|---|---|
| Physical form | Powder · granular · pellet · crystalline · liquid | Solid grades can be produced in more than one form from the same chemistry. |
| Compound (complex) NPK | Granules in which every granule carries the full declared analysis | The route when the customer needs a uniform granule that cannot segregate in the bag or in the spreader. |
| Bulk blending | Physical blending of single-nutrient and specialty granules to a target ratio | The flexible route: a ratio can be changed between batches without changing the chemistry. |
| Coating | Sulfur · humic · boron · iron coating, all at commercial scale. Dual-layer and biological coating in development. | Boron and iron coating are the house speciality: the micronutrient is built onto the granule rather than blended beside it, so it cannot segregate in the bag and it lands where the granule lands. |
| Chelation | Chelated zinc and chelated iron manufacturing; micronutrient compatibility work | Chelate type is stated per formulation. |
| Solubility | Fully water-soluble grades for fertigation and foliar | Solubility figures are declared per formulation from COA data, not estimated. |
| pH / acid activation | Acidic microenvironment granulation; pH-corrected solubles | The core answer to phosphate fixation in calcareous soil. |
| Application grade | Broadcast · basal · fertigation · foliar · drone ULV · centre pivot | 6 VAN products are already in commercial production in drone and ultra-low-volume grades; extension to the rest of the range is under review. |
| Batch size | 1 tonne minimum · 50 tonnes maximum in a single lot | Larger orders run as repeat lots to the same frozen specification. About 50,000 tonnes are made a year. |
| Pack formats | 1 L · 1 kg · 10 kg · 20–50 kg bags · 200 L drum · 1000 L IBC · jumbo bag | Formats offered per formulation, not as a fixed set. |
037 technology platforms
A brief is answered by combining platforms.
Each one is a capability VAN practises commercially today, not a research ambition.
| Platform | What it is | Where it already runs |
|---|---|---|
| Controlled release | Sulfur coating of urea at commercial scale; dual-layer variants in development. | Vital Urea (sulfur-coated urea) |
| Acid activation & humic coating | Acidic-microenvironment granulation with a humic seal, to slow phosphate fixation. | Green Phosphate 6-32-0 |
| Micronutrients | Zinc, boron, iron and multi-micronutrient formulation, granular and liquid; compatibility work for the tank. | V-Transform · V-Zinc · VL-Micromix |
| Humic delivery | Potassium humate in crystal, powder, pellet and liquid at several concentrations. | Humi Grow · Humi Grow Plus |
| Biologicals | A dedicated biological laboratory, established and running, with test production alongside it; phosphorus-solubilizing bacteria; compost and organic-carbon carriers. Strains are isolated locally and selected against Pakistani soil pH, climate and weather. | PSB · V-Compost |
| Micronutrient coating | Boron and iron coated directly onto the granule. The house speciality. Biological coating is a current development track. | Coated NPK grades and micronutrient-fortified phosphates |
| Solubles & precision grades | Fully soluble NPK and potash lines; low-salt, pH-corrected, drone-grade concentrates. | Vital Potash · VL-Potash Liquid · V-Germinator Pro |
04What VAN will not do
2 rules that do not move.
A formulation developed for a client does not reappear as a VAN brand or as a library code. Ever.
If an analysis will not survive 12 months on a Pakistani warehouse floor, it does not go on the label. We will tell you the fallback instead.
Start by telling us the problem: the crop, the stage, the soil and the price the market will carry. VAN works out the chemistry.
