CALCULATE YOUR
NUTRIENT SOLUTION
The exact grams of fertilizer per 200 L drum — with or without a water analysis
How many grams do you add to the drum? Stop guessing it by eye.
Time just once how long your pump takes to fill the drum and the app gives you the grams for Tank A and B, per irrigation and per week — from $900 a year, VAT included. Have a lab analysis? Pro mode calculates like a chemist and warns you when something is not safe.
Most recipes
are copied, not calculated.
A brochure or your neighbor does not know your water. Applying the wrong recipe burns roots, throws money away on fertilizer and caps your yield. These are the four scenarios that show up most often in the field.
Your water is not the water in the brochure
Every water source carries its own salts, bicarbonates and sodium. A generic recipe ignores that chemistry and can throw the whole nutrient solution out of balance.
A fertigation mistake is expensive
Burning roots, precipitating salts in the tank or wasting fertilizer on a badly calculated dose adds up to losses that far exceed the cost of getting it right.
Spreadsheets do not warn you when something is wrong
An Excel sheet does whatever math you ask of it, even when the result is not safe. It does not tell a ready-to-use recipe apart from one that needs more data.
Nutritional consulting costs $8,000–25,000 MXN/season
That is the real market benchmark. Nutrisurco.App runs the same calculation for a fraction of that cost — from $900 a year, VAT included.
The first fertigation calculator
that works like a chemist.
It is not a spreadsheet with hidden formulas. It is a calculation engine with the same discipline as a laboratory: every step is explicit and every number is traceable.
Your water analysis, converted to elements
Enter your lab report and the app converts it to the elements that actually matter for plant nutrition — not just to generic salts.
Optimization with mathematical programming
The engine solves a 3-stage lexicographic linear programming problem — not an average or a rule of three — to find the optimal dose with the fertilizers you have on hand.
Salinity check (EC)
Every recipe is validated against the target electrical conductivity for your crop and stage, so it never crosses the threshold that stresses the root.
A/B tanks with no precipitates
The app automatically separates incompatible fertilizers (calcium and sulfates, for example) between tank A and tank B so nothing precipitates in the irrigation line.
Acid calculation for bicarbonates
It determines the acid dose needed to neutralize the bicarbonate in your water, a step most generic calculators skip entirely.
Honest gate: "do not release"
If your analysis does not meet the minimum quality or consistency criteria, the app refuses to hand you a released recipe and explains exactly what is missing — instead of inventing a nice-looking number.
Every extra gram does not vanish: it ends up in your soil and your water
The fertilizer you apply "just in case" does not disappear: it leaches into the water table, salts your soil and washes away in the drainage — you paid for it twice, once buying it and once degrading your land. The exact dose is the cheapest environmental measure there is: you apply what the plant asks for, with the salts your water already carries counted in, and the rest stays in the bag. That is why Nutrisurco.App calculates with the fertilizers YOU have instead of prescribing the ones in the brochure: making better use of what is already in your storeroom protects your wallet and your soil with the same decision. It is the same non-negotiable line as Nutrisurco®: what does not care for your land, we do not offer.
What if I irrigate with a drum, no water analysis? — Field mode
That is how most people work: a 200 L drum, a pump, and fertilizer "by eye." Field mode solves it with what you already have: you time once how long your pump takes to fill the drum (that is your flow rate), you say how many hours you irrigate and how many times a week, and the app delivers the exact grams for Tank A and Tank B for each irrigation, the kilos per week, the protocol in order (A → rinse → B, so nothing precipitates and no drippers clog) and you can even uncheck the fertilizers you cannot get in your area — the app recalculates with what you do have. With the Advanced package you also capture your water's EC with a conductivity meter and the app uses it as a guardrail against salts.
What is the difference between Nutrisurco.App and a fertigation spreadsheet?
A spreadsheet applies whatever formula you ask of it, regardless of whether the result is safe. Nutrisurco.App solves a real optimization problem with your water and your fertilizers, validates every result against agronomic criteria and refuses to release a recipe that does not meet the minimum quality bar.
Do I need internet to use it out on the ranch?
Not to calculate. The engine runs on your phone or computer as an installable PWA; you only need a connection to activate the license the first time and, optionally, to verify that it is still valid.
Free DEMO mode,
no sign-up.
The DEMO mode runs on sample water so you can see exactly how the engine works: the conversion to elements, the optimization, the EC check and the honest gate. When you activate your license, you use your own water and your own soil.
Four steps, no friction.

What people ask before
activating their license.
Does Nutrisurco.App work without internet?
Yes. The calculation engine runs on your phone or computer — it is an installable PWA. It needs no connection to calculate your recipe. Internet is only needed to activate the license the first time and, optionally, to verify that it is still valid.
What happens if my water is not safe for a recipe?
Nutrisurco.App has an honest gate: if the analysis does not meet the minimum quality or consistency criteria, the app tells you explicitly and explains why, instead of handing you a released recipe with no basis.
Do I need a water analysis to use it?
No. Field mode (Basic package, $900/year, VAT included) works with your 200 L drum and your pump: you time once how long it takes to fill the drum and the app tells you the grams of each fertilizer per drum and per week, with the protocol so nothing precipitates. With a lab analysis, Pro mode gives you the full calculation with your real water.
Can I upgrade my package later?
Yes, whenever you want: you keep the same code and your data. The upgrade (Basic → Advanced → Pro) activates on your next start with internet, and you only pay the difference prorated to the time left on your license.
How many devices does each license include?
Basic, Advanced and Pro Grower include 1 device. The Agronomist/Consultant plan includes 3 devices and lets you sign reports for your own clients. Need more devices? It is adjusted with your same code.
What does "professional recipe not released" mean?
It is our honest gate at work: every recipe comes out with its explicit status. Professional recipes are in field validation (trial in progress); the app shows you the full calculation, its traceability and exactly what is missing to release it — instead of faking a certainty that does not exist yet. It is also why the 14-day refund is no questions asked.
How do I receive my code?
Pay online with a card, Mercado Pago or PayPal and your activation code arrives by email automatically. Prefer a personal touch? Request it on WhatsApp and it arrives the same day.
Is there a refund guarantee?
Yes, a 14-day no-questions-asked refund from the moment your license is activated.
Why is it annual and not monthly?
Because your crop's real cycle is the season, not the month. The annual subscription saves you from reactivating mid-cycle and is the price the plans on this page are calculated with.
