AI nutrient planning: Agmatix vs Fyllo vs OneSoil

Choose the fertilizer decision

A fertilizer decision can involve building a whole-season nutrient program, adjusting fertigation to crop stage, or varying an application across a field. Agmatix Digital Crop Advisor, Fyllo Nutrition Advisory, and OneSoil Platform support those tasks through different information paths. This comparison focuses on nutrient and fertilizer planning, with crop sensing and AI advice distinguished from direct laboratory measurement.

Agmatix Digital Crop Advisor

Agmatix Digital Crop Advisor creates field-level nutrition plans from agronomic data and crop requirements. Its documented workflow combines soil, water, and tissue analysis with information such as expected yield, soil characteristics, historical performance, and crop development stages. Plans can include nutrient needs, fertilizer products, and application rates, with reporting that helps advisors share the result with growers. The vendor describes support for up to twelve nutrients and a broad crop library, as well as preseason and in-season planning. Controlled-release fertilizer behavior and the timing of nutrient availability can also form part of a plan. This makes Digital Crop Advisor relevant to agronomists managing complete nutrition programs across growers rather than simply observing a stressed patch of crop. Its current positioning combines AI, environmental data, and agronomic expertise. The value lies in organizing those inputs into an adjustable recommendation. Actual crop coverage and the available local agronomic data still determine how well the plan matches a specific farm.

Fyllo Nutrition Advisory

Fyllo Nutrition Advisory connects local field measurements, crop models, and mobile guidance. Nero Infinity supplies soil-context data through a sensor and app workflow, while the wider platform combines AI with agronomy models tailored to crop, variety, and growth stage. Fyllo’s grape-specific documentation describes petiole nutrient analysis and stage-wise NPK and micronutrient fertigation recommendations. That makes it relevant to supported horticultural operations whose fertilizer timing and delivery are closely connected to crop development and root-zone conditions. Its practical interface emphasizes an actionable recommendation on the farmer’s phone rather than requiring the grower to interpret every graph. The distinction between inputs matters: sensor moisture, temperature, or electrical conductivity provides context, while tissue or soil analysis supplies different nutrient evidence. A sensor should not be assumed to directly measure every nutrient mentioned in the advice. Fyllo suits farms that can use the supported local hardware and crop-specific advisory service, with geography, connectivity, and service coverage part of the selection.

OneSoil Platform

OneSoil Platform combines field monitoring and AI agronomic support with precision-application workflows. The Pro tools build management zones and variable-rate maps using productivity information, selected satellite vegetation imagery, or soil-test results. Agronomists can edit zones, set application rates, create control strips, and move prescription data to machinery, including through John Deere Operations Center integration. Its AI Agronomist uses field context, weather, crop history, and the vendor’s own analytical models to help interpret what needs attention. This is useful when the fertilizer question is spatial: which parts of a field should receive different treatment, and how does the prescription reach the applicator? Mobile supports field observations while Pro adds planning and analysis tools. OneSoil therefore suits arable farms and advisors connecting field variability with application execution. A satellite stress signal does not by itself identify a precise nutrient deficiency, and the AI layer does not replace the soil-test inputs used to construct a nutrient-specific prescription.

A nutrition program, a timed action, or a field map

Agmatix organizes crop requirements and agronomic analyses into a nutrition program. Fyllo ties supported crop-stage advice to changing local field conditions. OneSoil organizes variability into zones and application maps. An advisor designing fertilizer products and rates over a season will find Agmatix’s planning structure relevant. A horticultural grower deciding when to fertigate can benefit from Fyllo’s sensor and crop-stage context. An arable operation applying different rates across one field should examine OneSoil’s prescription workflow. These approaches can be complementary because a seasonal plan, a timing adjustment, and a spatial map answer different questions.

How evidence reaches the next decision

Agmatix accepts laboratory and agronomic information, then produces plans and reports that can be shared with growers. Fyllo combines field sensing with phone-based recommendations and crop-specific analytical inputs. OneSoil uses field boundaries, imagery, productivity zones, and optional soil tests to create editable prescriptions and machinery exports. Their interfaces therefore fit different working relationships: advisor-to-grower planning, day-to-day farm guidance, and agronomist-to-applicator execution. Agmatix is strongest when the central task is a complete nutrient program; Fyllo when advice must follow supported crop stages and local conditions; OneSoil when rates need to vary across management zones and reach compatible equipment.

Separate advisory access from equipment and maps

Agmatix and Fyllo numeric prices and billing intervals remain unconfirmed. Fyllo’s sensor, connectivity, and advisory scope need to be considered together. OneSoil describes monthly and annual Mobile subscriptions, regional/hectare-based Pro pricing, and a limited Pro trial; exact amounts and Pro billing terms remain unconfirmed. Basic free access does not establish free variable-rate tools or unlimited AI advice. Compare supported crops, hectares, data inputs, hardware, users, and the required output. A mobile monitoring subscription is a different purchase from a complete nutrition-planning service or a sensor-supported advisory engagement.

Which should you choose?

Consider Agmatix for whole-program crop nutrition planning, Fyllo for supported horticultural fertigation advice, and OneSoil for variable-rate fertilizer maps and field execution. Choose according to whether the missing step is the nutrient program, the timing decision, or the spatial prescription.
