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

Evaluation of the most important fertilizer recommendation systems through the results of Hungarian field (IMPHOS) experiments

Summary of the IMPHOS experiments, 2004-2006

Comparison of the profitability of advisory systems on the basis of the average of the results of IMPHOS experiments I (Csathó et al, 2007;. Sulyok, 2004, 2005, 2006) winter wheat 2004 2005 maize spring barley 2006

Comparison of domestic advisory systems profitability Based on the mean yields of IMPHOS II trials. The average of 3 years and 3 areay

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). 12.

Operating references from individual farmers 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
