Revolutionary system approach

Plant-Soil-Environment: Three-Way Approach of FITOPEDON® concept
FITOPEDON® technology leaves behind old-fashioned approaches and - in a revolutionary new way - considers the plant-soil system as a controllable composite dynamic unit. In this controlled system there are several times more factors that can be - and should be - considered concurrently, so optimum nutrition of the given plant can be achieved by a gradual approximation. About two decades of operational experiences proved the results of previous researches in an exceptionally large number of cases.

The most important conclusions of the FITOPEDON® model are:

  • There are unique relationships existing between every soil, plant and life cycle.
  • Several soil-plant interactions should be investigated at the same time.
  • Former soil and plant testing methods are not sufficient.
  • Nutrient supply adapted to the genetic program of the plant multiplies yields (up to 5-10 times) and increases immunity.
  • Such an increase can be achieved that largely exceeds the already well-known results of GMO experiments.

The key to the FITOPEDON® technology

The key to the FITOPEDON® technology is to "serve" the plant optimally according to the current given circumstances. 

  • Service

Meeting the always-changing nutritional requirements of a given plant.

  • Specific circumstances
Soil conditions, environmental factors, plant development phases.

  • The source of data on the nutrient uptake of the plant

As a result of several decades of experimentation and data processing, a data warehouse has been built with mathematical methods that utilize it to predict the nutrient demand of the plant and to meet the development phases called phenophases.


  • Data handling

Continuous collection of measurement data from season to season and phenophases. Computer processing of data according to seasonal, medium and long term needs. Corrections, regulations on seasonal, medium and long-term levels. Making suggestions to the producer on how to reach optimum.

Components of FITOPEDON® Knowledge Base

All the elements of the soil-plant system and those of its environment
The scientifically proven techniques and knowledge which are the basis of the FITOPEDON® know-how:

  • Quantitative characteristics of the turnover of nutrient elements in soil-plant systems,
  • The technological framework for dynamic plant nutrition,
  • The system of instructions containing the practical procedure of nutrient resupply,
  • Parameters of plant mineral nutrition for 22 cultivated plant species and their varieties have been tested in experiments and applicated in farmland so far,
  • The measurements have been executed on 20 types of soil that cover the dominant part of the cultivated habitats of the plant species’ in question,
  • Results of own measurements of soil physics, soil chemistry, and the special FOFRAK and SITOBI-based experiments.

Starting point

Plants, like all other living organisms, are made of cells and their differentiated associations. Respectively they live, develop and produce in their own environment and utilize their genetic potential by their genetic program for their own benefit and survival. Both the need for water and of other essential mineral nutrients together with the energy demand can be measured and identified on any day of its development cycle or by a given period of day, according to the genetic program of the plant (even if it is perennial). The cultivated plant’s exact nutrient demand we get to know this way can be supplied, which is necessary for the plant in its different stages of development in order to optimally regulate the utilization of the genetic potential both in quantitative and qualitative sense. Therefore the increased yield, the better yield quality, and plant resilience can be realized by the application of appropriate new cultivation techniques like the FITOPEDON® method, which consider exactly these facts. 

Measuring nutrient requirements of plants per phenophase
The effects of soil-plant interaction processes are calculated and interpreted in their dynamics (changes). Examining these processes leads to the exact determination of what the plant „needs”. This is where the plant’s own genetic program development is also expressed (indicated). 

  • FITOPEDON® Soil Nutrient Supply Model
The temporal changes in nutrient absorption, nutrient fixation, and nutrient supplying capacity of the soil should be determined.
The soil test methods providing static data would not be sufficient, so the soil nutrition service dynamics are determined by the FOFRAK1 soil test method.

  • FITOPEDON® Plant Nutrition Model
To determine the mineral nutrient needs of economically most significant plants, our database now contains 16 000 - 36 000 measured cases on 15-64 levels of nutrient supply. The currently known FITOPEDON® models are related to numerous varieties of the 22 remarkably important plant species. 

  • FITOPEDON® Environmental Model
In addition to the traditionally considered environmental variables, it is necessary to take into account the optimum mean temperatures of the given periods in the phenophases and the irradiated energy quantities of photosynthetically active radiation in the self-learning decision-supporting algorithms.


  • Previous soil and plant examination methods alone are not sufficient for the application of FITOPEDON® cultivation technology and therefore new ones should be used.
  • The dynamic changes in soil-plant system should be simultaneously examined and the steps of cultivation technology imporvements should be adjusted to these.
  • The nutrient supply adapted to the plant genetic program can multiply yields (up to 5-10 times), improve quality and enhance plant resilience and immunity.
  • A remarkable increase can be achieved without the significant risks of genetic modification. The better utilization of the given genetic potential of the given plant species is far beyond the results of GMO experiments (which often indicate hardly a few percent excess). The advantages of the preservation of the main features crafted by long evolution are obvious, and it has proven to be a reliable genetic inheritance that has never been harmful in crop production practices of hundreds of years. This fact is well-known for anybody.

Plant Nutrition by „Pinpoint” Precision - Multiple Crop Yield

  • During its growth, the plant gradually approaches the optimum state - significant yield increase, better content, higher resistance are expectable.
  • With a few years of FITOPEDON® soil-plant management, the yields of plants can be enhanced to the upper limit of the utilization of their genetic potential and the cultivated plants will provide several times more crop yields than what was usually expected on a given soil.
  • The elimination of the ineffectively used doses and/or nutrient leaks reduces both the production costs and harmful soil loads.
  • By optimizing the nutrition supplying power of the soil, the unnecessary load on the environment decreases.
  • By applying the FITOPEDON® procedures and following its expert advice, even a less experienced farmer can achieve good results.
  • Crops of extra quality can be grown, that are competitive for both domestic and foreign markets.
  • Production of "bio" quality crops can be enhanced.
  • Due to the purposeful crop rotations and the reasonably planted permanent plant infrastructure, land prosperity can be achieved several times in a year, meanwhile soil fertility is also maintained or even improved.
  • The areas of main or complementary industrial and agricultural activities and mining activities can be revitalized and recultivated in a nature-friendly way in suitable harmony with the characteristics of the microregions.
  • It is possible to create a significant number of new jobs.
