(4) Ca-IDHA is a fertiliser providing plants with the macronutrient calcium. When assessing the conditions for its inclusion in Regulation (EC) No 2003/2003, this type of EC fertilisers has been found to be agronomically efficient. Regulation (EU) 2019/1009 should be amended to take into account the technical development occurring after its adoption and thus the minimum content of calcium oxide in straight solid inorganic macronutrient fertilisers should be lowered from 12 % to 9 %. Lowering the minimum content of calcium oxide would introduce this type of fertiliser in the scope of the harmonisation rules and thus facilitate its free movement in the single market. This adaptation is linked to the agronomic efficiency criteria of the fertilisers, and is not lowering the high standards of protection of human health and of the environment laid down in Regulation (EU) 2019/1009.

(5) Regulation (EU) 2019/1009 should therefore be amended accordingly,
