Important reasons to choose organic!

  • Organic fertilisers are of benefit to the soil, not just the immediate crop.

  • Natural products based on kelp, rock minerals, fish and animal manures have a slow release.

  • Chemical fertilisers are highly soluble so may wash into the waterways causing toxic algal blooms.

  • The fast, lush growth caused by chemical fertilisers also attracts pests and fungi to the plants.

It uses Tasmanian seaweed in a cold-press process. Kelp contains a comprehensive range of trace elements and amino acids essential to maintaining an organic garden. Use to:

  •  soak seed, seedlings and new fruit trees to reduce transplant stress

  • increase fruit production by foliar spraying

  • increase tolerance to heat, cold, drought , pests and diseases

Depending on application rate, 1 litre makes up to 250 litres; 5L makes up to 1250L..

Organic Guide to Composting 
How do you decide which fertiliser to use?

For gardeners with large areas, planning new orchards or market gardening, a soil test is essential. It gives you a starting point to judge your soil's improvement over the years and identifies initial problems that have to be addressed. Without the information from a soil test, large sums of money can be wasted on inappropriate fertiliser applications or young trees lost due to nutrient deficiencies.

For home gardeners it is hard to go wrong just adding compost to the soil, with organic seaweed or fish fertiliser to help seedlings along. Organically certified fertilisers such as Huma-Tech Liquid Humus and Organic Garden Booster can safely be used in any gardening situation. Soils vary a great deal from region to region, in some areas of Australia soils are low in magnesium whereas SE Queensland is the reverse, often far too high in magnesium but low in calcium. As a general rule Australian soils are deficient in trace elements which is why a seaweed spray such as Natrakelp is a useful addition.

Checking with a local organic gardening organisation will give you the benefit of the members long experience and understanding of your area's climate and soils. See our links page for  websites.

Why buy organically certified fertiliser?

English is a constantly evolving language and changing all the time. Many words have several meanings and 'organic' is one of these. 'Organic' meaning carbon-based is one meaning used as the opposite of inorganic. Grown without the use of chemical fertilisers and pesticides is simply another meaning, that has developed semantically since the early 1900's. This is obviously a valid meaning as the function of language is communication and this meaning is understood by millions of people world-wide.

Organically certified fertilisers are those where the original materials and the processes to manufacture them have been audited by an organic certifying organisation. This means that tests are done for heavy metal residues and chemical residues such as fungicides. To give an example, gypsum mined as rock could be available 'organically certified'; gypsum as a waste product from gyprock manufacture with residues including fungicides could not be 'organically certified'.
