Boron Manganese Iron [Chlorosis] 3.3 Fertilisation Fertilisation (organic or inorganic) should only be undertaken where and when required in order to reduce potential for water pollution (nitrogen and phosphorus leaching), air pollution and unnecessary energy costs. Guideline Achieved? Guideline categorisation YES/NO A. If fertilisers are required, organic options are used Best practice preferentially (e.g. cover crops, nitrogen-fixing and deep rooting plants, compost, manure, green manure, mulch). B. Nutrients are only applied if petiole and soil analysis, vine Minimum standard vigour, and visual observations of nutrient deficiencies indicate they are needed. Minimum standard C. Follow the IOBC guidelines in regard to Nitrogen application. D. Use of fertilisers or manure contaminated with toxic or Proscribed environmentally-hazardous substances such as heavy metals or pathogenic micro-organisms. 3.4 Cover cropping Ground cover can be: Temporary: Planted in the autumn and destroyed in the summer Permanent: Planting permanent cover crop or allowing natural vegetation to grow Plant cover can improve: water infiltration, nutrient supply for soil organisms, soil structure, soil fertility and organic matter, water-holding capacity, biodiversity, biological pest-control, and increase humus content. Plant cover can consist of grasses or legumes and is regarded as a term cost-effective way to increase the amount and persistence of soil organic matter. Guideline Achieved? Guideline categorisation YES/NO A. Ground cover is present in 50% of the vineyard throughout the Best practice year. B. Ground cover is present in vineyard inter-row alleys in the Minimum standard winter. 4. Integrated pest management Integrated Pest Management (IPM) is a pragmatic ecosystem based management practice that integrates biological, cultural, physical and chemical tools to manage pests and diseases in
