Plan your crop fertilization based on agronomic data

FertiPRO calculates, documents and justifies every fertilization plan

FertiPRO calculates the crop nutrient balance and generates structured fertilization plans for each parcel by integrating soil, water, and organic amendment data.

Plan your crop fertilization based on agronomic data

FertiPRO calculates, documents and justifies every fertilization plan

FertiPRO permite calcular el balance nutricional del cultivo y generar planes de fertilización estructurados por parcela, integrando datos de suelo, agua y enmiendas orgánicas.

Fertilization planning is no longer optional.

Mandatory registration starting January 2026

Royal Decree 1051/2022 requires documenting every fertilization operation. Without a digital system, compliance becomes difficult to manage at scale.

The agronomist signs the plan using their REGFER number

From July 2026, advisors registered in REGFER will be technically responsible for each fertilization plan. Free tools do not generate reports with verifiable supporting documentation.

Manual calculations are no longer sufficient

NPK, mesonutrients, micronutrients, organic matter, NVZ, irrigation, cover crops… A complete nutrient balance in Excel takes hours. FertiPRO does it in minutes.

First you see what the parcel needs.
Then you decide how to supply it.

The Start plan provides a complete nutrient diagnosis — NPK balance, organic matter and NVZ alerts. The Expert plan adds execution: application distribution, fertilizer selection and a traceable report signed by the agronomist.

START PLAN – DIAGNOSIS

What does this field need?

The engine calculates the complete nutrient balance for your crop, field and growing season.
N, P, K balance + meso- and micronutrients
Soil and water data via official API
Automatic NVZ detection
Soil organic matter balance
EXPERT PLAN – FERTILIZATION PRESCRIPTION

How do I meet those needs with real fertilizers?

Define the strategy, distribute fertilization across applications and select each fertilizer product.
Basal, top dressing, foliar and fertigation applications
Fertilizer selection and real-time calculation
PDF report with REGFER number · Excel · Power BI
Campaign history and plan duplication

The agronomic calculation engine is the same in all plans

Nutrient balance, integration with official data, ZVN alerts, and fertilization strategies all work the same in both the Start and Enterprise plans. What distinguishes the paid plans is the ability to execute, document, and analyze this work at a professional scale.

Integrated SIGPAC

Five steps. A complete plan

The FertiPRO process is designed for the technician to decide—not calculate. Each step is guided, and data is automatically uploaded when available.

1
📍

Parcel

Select the SIGPAC parcel and link the farm area.

2
📊

Agronomic data

It integrates soil, water, organic amendment, or manual analysis.

3
🧮

Nutritional Balance

It automatically calculates the necessary fertilizer units for the crop.

4
🌱

Fertilization plan

Organize the base fertilization, topdressing, fertigation or foliar applications.

5
📄

Export

Generate the plan in PDF, Excel, or integrate it into analysis tools.

A complete agronomic engine

It’s not a generic recommender. FertiPRO integrates all the factors involved in the nutrient cycle — and makes them available to the technician in a real workflow.

Calculation Engine

NPK + meso + micro + organic matter

Complete mass balance for N (actual inputs and outputs), STL strategy for P and K, mesonutrients and microelements, humus balance with isohumic coefficients K₁ and mineralization rate K₂.

Automatic ZVN.
REGFER included

If the plot is in a Vulnerable Zone, FertiPRO automatically applies the limits and restrictions. The report includes the REGFER number of the responsible technician.
Analytical data

Official API + own data

Automatic connection to the ITACyL and ArcGIS databases. If you have your own more recent analytics, you can enter them manually and the plan will adjust to your actual data.
