OceanFert® Granular Seaweed Fertiliser is a slow release fertiliser. Soil micro-organisms breakdown and decompose the solid granules over a long period of time; slowly releasing nutrients and compounds as the growing plants require them. OceanFert® is a naturally derived soil conditioner. It will increase soil organic matter; improve soil physical structure and enhance fungal and bacterial activity in the soil. Use as part of your conventional fertiliser program and is certified for use on organic crops.
