4. The intensive and environment-friendly fertilization
advisory systems philosophy
Intensive nutrient supply system
(NAK MÉM 1979, 1981)
Strive to reach Maximum yield
The goal was to fertilize the soil
To reach and maintain good or very good PK supply of the soil
To fill the soil with PK fast
Each year PK-fertilization
PK-fertilization by all kinds of PK supply level
Bigger critical values for soil nutrient supply
Unified critical values for soil nutrient supply
Bigger specific nutrient content
The specific nutrient contents are independent from the planned yield levels
Environmentally friendly fertilization system
(TAKI ARI-1998)
Strive to reach economic yield
The goal was to fertilize the plant
To reach and maintain medium PK supply of the soil
To fill the soil with PK slowly
Periodic PK-fertilization
PK-fertilization by good, medium or weak PK supply level
Smaller critical values for soil nutrient supply
critical values for soil nutrient supply are depending on plant species
Smaller specific nutrient content
The specific nutrient contents are dependent on the planned yield levels

15. The farmer can make a double fault known from tennis:
He fertilizes, where he should not fertilize
( More fertilizer than necessary).
He does not fertilize, where he should fertilize
( Less fertilizer than necessary).

Baranya County 120 acres of £ 1.5 million in fertilizer price savings / 1 year
Heces County: 300 acres of £ 4.5 million in fertilizer price savings / 1 year
So far,
about 750 thousand hectares advised by our
Pro Planta system
