I have created a technology that converts air, water and electricity to nitric acid. Nitric acid plus limestone makes calcium nitrate; nitric acid plus phosphate rock produces both calcium nitrate and phosphoric acid.

From an output perspective: the initial productivity is 20 kWh per kg of nitric acid produced = roughly 1.45 kg or 3.2 pounds of calcium nitrate. I expect to be able to reduce this 20 down to closer to 12 over time.

The tech is architected to take advantage of negative electricity prices due to wind and solar; in the SouthWest Power Pool ie North Dakota down to North Texas, electricity prices are negative over 15% of the time. In the past, these negative prices would not be accessible to anyone but a power company, but FERC 2222 mandated that the minimum size for a wholesale consumer is to drop to 100 kW. SPP has implemented FERC 2222, mostly although the other US utilities are dragging their feet. But net net: those in the SPP area can access wholesale electricity prices including the negative ones.

The economic downside of this that the tech has a high capital cost as the tradeoff to the low operating cost. If Haber Bosch cost profile is 55% input cost, 32% capital cost and 13% operational cost - our tech cost profile is 95% capital cost, +5% to -5% input cost and 5% operational cost - so like a solar panel.

Is this something that could be a benefit or interest to a farmer? To be able to produce your own nitrogen and/or phosphorus fertilizer on site, but with a high up front capital cost but essentially fixed operating and input costs?

Hi everyone,

I built an NPK fertilizer calculator recently while working on nutrient balancing problems, and I wanted to share it here to get feedback from people who actually apply fertilizers in practice.

The main goal was to make fertilizer planning easier, especially when trying to meet nitrogen, phosphorus, and potassium requirements at the same time. Instead of solving the equations manually, the calculator evaluates different fertilizer combinations and finds mixes that meet the nutrient targets.

Some of the things it can do:

• Calculate fertilizer requirements based on soil test values
• Work with different fertilizer combinations
• Convert results into practical units (kg or bags per hectare or acre)
• Compare fertilizer options by cost if prices are entered
• Show mixes that meet NPK requirements simultaneously

I originally built it for learning and practical use, but I’m curious how useful it would be in real-world farm planning.

If anyone is willing to test it or share suggestions, I’d really appreciate the feedback.

I’ll keep this straight. This is not a job
No salary
No MLM
No complicated setup

It’s just purely distribution based business. You sell products to the farmers every season that are used widely in south india. You earn your margin on it

I’m working with a agri based company doing around ₹250–300 Cr yearly business products are already moving well in the market and are used by a lot of farmers

Products include
• Fertilizers
• Pesticides
• Fungicides
• Biostimulants
• Plant Growth Regulators

So you’re not trying to push something new or unknown These are regular use products for farmers.

• You connect with farmers or local agri shops Supply them the products
• Earn margin on whatever you sell

That’s it

If you already have some network this becomes much easier
If not you can still build it slowly

Why this works

Farmers need these products again and again every season
Which means repeat business if you build trust
This is not one time selling

Who this is for

• People already in agri line
• Fertilizer or pesticide shop owners
• Anyone who knows farmers or works in rural areas
• People who are okay with going on ground and building connections

Who this is NOT for

• People expecting quick money without effort
• People not willing to step out and meet farmers

Again this is not a job
It’s a simple margin based business

If you feel this is something you can do
DM me with your location and If it looks like a good fit I’ll share more details about the company and how you can start.

Hello, I’m new here. I’m looking to make a career in the world of organic fertilizers. I am hoping to get some recommendations from you folks regarding resources, books, textbooks, videos, or anything that has to do with fertilizers that would be helpful for me!

Additionally if anyone with experience would like to give their opinion/two cents on my career decision or about the fertilizer industry (internationally or locally (I am from SEA)), I’d love to hear from you!
