Quality of Liming MaterialsThree Steps Control Systems in Germany

1. Controlling by Producers within the Production Process

2. Controlling by National Authorities, organizedby regional boards(occasional, rare)

3. Controlling by private Organisation - external- independent- systematic

29

Quality Control Systemson Fertiliser Lime in Germany

History• 1896 Advise by German Agricultural Society (DLG)• 1930 National Farmer Leader:

„Guidelines to the Collocation of Fertiliser Lime Market“

• After World War II1st Quality Control System with VDLUFA(German Agricultural Analyse and Research Association)

• 1964 Fertiliser Lime Agreement with VDLUFA (new)• 1994 Quality Protection System by RAL-Organisation• From 2009 Quality Protection System by DLG

30

Control StrategyTrust is good - Control is better

• Occasioned by authority• Own initiative

- internal process and product control

- Independent externalprocess and product control

31

NewFertiliser Lime Control System

Independent Commission as central board:

• Setting minimum standards• Controlling the DLG system• Decisions on critical causes

• Certification

32

Control StrategyWhy independant ???

- Audits make the production process safer- Analysis shows product quality- Certification makes transparent- Transparency creates trust- Trust supports marketing

Multi benefit system:Win–win – constellation for

Producer – Trader – Advisor – Farmer - Authorities

• Products - Classification- Description and minimum requirement- Product impact on soil pH

• Analysis - Reactivity- Size distribution- Ca/Mg – content- CO2- NV- Moisture- Breakdown of granules

• Others - Vocabulary- Lime Requirement- Product impact on soil pH
