high-n_5HIGH N

High N (12%N) is an organic granular, fertiliser based on feather and malt waste. All the N is available within three months of application. Each granule also contains 1% phosphorus, 0.5% Potassium, magnesium, calcium and trace elements (Fe, B, Mo, Mn, Zn

High N is GMO free and approved for use in organic agriculture according to EU regulation 889/2008 (requires justification as per Organic Food and Farming Standards in Ireland)


DOLOPHOS P 11 is a granular mineral based product that provides slow release Phosphate throughout the growing season for use in Horticulture, Tillage and Grassland.  It also contains important secondary nutrients including 30% Calcium, 2% Magnesium (MgCO3). also Manganese, Zinc, Copper and Molybdenum.

Phosphate is vital for root growth and plant establishment.  Due to the gradual release High P matches crop uptake.

Symptoms of Phosphorus deficiency
- poor growth and root development
- leaves that turn blue/green and become stiff
- fruits small and acid tasting
- poor yield of fruit
Phosphorus deficiency may be confused with nitrogen deficiency.
Particularly susceptible are Carrots, Lettuce, Spinach, Apples, Currants and Gooseberries.

Application rate
Maintenance application appr. 2 - 3kg DOLOPHOS P 11 /100m2.
Tillage 200-400kg/ha
Grassland 200-300kg/ha
Higher application rates depend on the scale of the deficiency which can be determined by a soil test.

DOLOPHOS P 11 7% is soluble in a 2% formic acid solution

Approved for use on organic holdings subject to approval from your certification body.


High K

High K (26%K) is a granular, plant extract, that supplies 100% water soluble potash. Each granule contains 26% potassium, 8% sulphur and a range of trace elements (Mn, Cu, Zn,I,Mg).

Potassium (K) is vital to crop yield and quality and is usually the nutrient required in the largest amount compared to other major nutrients. It is also vital for flowering, colour, sugar formation and water balance.

High K does not contain chlorine, unlike synthetic sources of potash. Chlorine interferes with nitrogen uptake and can have an adverse impact on the microbial health of the soil. The potash in High K is much more readily available to the crop than rock potash which is not water soluble.

High K is GMO free and approved for use in organic agriculture according to EU regulation 889/2008 (requires justification as per Organic Food and Farming Standards in Ireland)



Patentkali is sulphate of Potash containing Magnesium.

Patentkali is a highly concentrated fertiliser containing the nutrients potassium, magnesium and sulphur in an ideal ratio:

  • 30 % K2O water-soluble potassium oxide (25%K)
  • 10 % MgO water-soluble magnesium oxide (6% Mg)
  • 17 % S water-soluble sulphur trioxide (17% S)

Patentkali is a unique, naturally occurring potash fertiliser from Germany where there are vast deposits underground. How was it created? Most of Central Europe was covered by an inland sea more than 250 million years ago, which was largely cut off from the open sea by shallow straits, known as Bars. Since a desert-like climate predominated at that time, the intensive solar radiation evaporated the water, like in a gigantic evaporating pan.

The salinity of the body of water increased until the dissolved minerals (carbonates, sulphates and chlorides) crystallized out and formed layers of potassic minerals. This led to the development of vast deposits, some of which are several hundred meters thick. As a result, we have a natural product at our disposal today that was created from pure sea water by the heat of the sun at a time when there was no pollution.

Patentkali is approved for use on Organic holdings (restricted input - requires justification as per Organic Food and Farming Standards in Ireland)


seaweed-dustSeaweed Dust

Seaweed Dust is a completely natural product made from Seaweed (mainly Ascophyllum Nodosum) which grows in the inter-tidal zones of rocky shores at the Irish Atlantic coast. Seaweed is unique in it's ability to absorb from the sea the abundant supply of minerals and trace elements.

The benefits of seaweed to the soil are well known - farmers in coastal areas have applied seaweed to potato and vegetable plots for centuries.

Seaweed Dust is an unaltered natural product which contains an unequalled range of minerals, trace elements, vitamins and amino acids.

Seaweed Dust is GMO free and approved for use in organic agriculture according to EU regulation 889/2008

(requires justification as per Organic Food and Farming Standards in Ireland)


Trace Elements & Minor Nutrients

Minor Nutrients and Trace Elements are vital to plant growth - but are only needed in small amounts. Deficiencies should be identified by either soil or plant inspection and analysis.

Some of the major soil factors which can cause micronutrient deficiencies in crops are:

  • High soil pH levels
  • High salt content can adversely affect uptake
  • A high calcium carbonate content in the soil
  • Sandy or peaty soils with low nutrient content
  • Failure to add micronutrients to the soil in the wake of intensive cultivation

Our Trace Elements are GMO free and can be used in organic agriculture (requires approval from the Certification body - as per Organic Food and Farming Standards in Ireland)

Give us a call on 027 50710 to discuss your soil analysis and we can suggest appropriate organic approved products.


Liquid fertilisers

vinasseVinasse liquid - is a natural N(4.5) -K(6) fertiliser

Vinasse is a by-product of the sugar industry, made through fermentation of molasses. Vinasse liquid can be taken up by plant foliage immediately because the Nitrogen is available in protein form. The proteins together with the sugar residues have the additional effect of stimulating the micro-organisms in the soil. Due to the high potassium content Vinasse is very good for finishing crops.

Vinasse is GMO free and approved for the use in organic agriculture according to EU regulation 889/2008.

Myko Activ Bio

Myko Activ Bio 7-3-7 is a natural fertiliser and soil activator with mycorrhizal fungi

Myko Aktiv Bio contains living mycorrhizal fungi. Most plants have a symbiotic relation with these natural funghi. This means the plants benefit from the fungi while the fungus is supplied with nutrients by the plant. mycorrhiza form a very dense mycelium root network around the roots of the host plant. This network transports water and nutrients to the plant andmyko-activ enhances the plants metabolic processes. The plant roots get an extra growth stimulation.

Myko Aktiv Bio contains plant based waste from food processing, living mycorrhiza (Globus sp) on substrate, micro-organisms, hornmeal, vinasse.

What are effects of mycorrhizal Symbiosis on plant-soil system?

  • Increased efficacy of nutrient acquisition, plant growth, flower formation and crop yield.
  • Enhanced resistance to drought, environmental stress and some root pathogens.
  • Reduced plant mortality after transplantation.
  • Improved plant fitness in stressed environment.
  • Positive effects on soil aggregation and stability and soil water retention.
