Paragraph 9 I1
England, Wales and Scotland
In the case of fluid fertilisers, additional information on the fertilising components may be expressed in equivalent terms of weight versus volume (kilograms per hectolitre or grams per litre). In the case of fluid fertilisers which are for foliage spraying, the soluble calcium content may be declared if it is not less than 8% calcium oxide (5.7% calcium).
