Nu-Gro liquid fertilizers are finely ground fishmeal suspensions and are universally acknowledged as the best organic liquid fertilizers available. It is our belief that the unique combination of nutrients, amino acids and proteins in fishmeal produce a high quality fertilizer. Trials by the Henry Doubleday Research Association have shown superior results over other organic based-liquid fertilizers and Nu-Gro is the market leader in its class.
All Nu-Gro products are manufactured using micronised fishmeal derived from a Soil Association approved source. This is combined with other approved additives, which are also micronised and filtered, to give a fine colloidal suspension, capable of being sprayed or applied through drip irrigation systems.
All products in the Nu-Gro range are fully accredited by the Soil Association as "approved organic fertilisers under the Restricted Use Scheme".
The Nu-Gro range has recently expanded to 4 liquid products, in order to cover a broader range of crops, soil types and growing conditions:
Nu-Gro Original
A high analysis fertilizer with a full range of secondary and micro-nutrients. Used as a starter feed for transplants or as a tonic for plants growing in waterlogged/stress conditions.
Nu-Gro 5-2-5
A balanced NPK liquid suitable as a general feed for all plants
Nu-Gro 6-1-3
A high Nitrogen feed suitable for use on leafy plants or where a Nitrogen boost is needed on vigorously growing plants.
Nu-Gro 4-2-8
A high Potash feed suitable for flowering/fruiting plants or where a Potash boost is needed in deficient soils.

Nu-Gro liquids provide a high level of Calcium in gradual release form, together with organic constituents (proteins, amino acids and globulin) which decompose slowly to provide improved earthworm/microbial activity in the soil. Nu-Gro liquids have also been observed to act as a sticker/spreader helping to improve the efficacy of other spray materials.
Nu-Gro liquids are packed in 10 litre bottles (2 per outer), or non-returnable 200 litre drums
