One natural source · a broad spectrum of nutrients
One litre.
Four hundred litres of feed.
SaproGro™ is a registered organic liquid fertiliser made from Baltic freshwater sapropel — a mineral-rich lake sediment that naturally carries a broad range of macro and micro nutrients. Highly concentrated: one litre makes up to 400 litres of ready-to-use feed.

Beyond N-P-K
Most feeds cover three nutrients. Plants draw on many more.
Standard fertilisers concentrate on nitrogen, phosphorus and potassium. Plants also use a wide range of other macro and micro nutrients — and SaproGro™ delivers that broader spectrum from a single natural source, in one bottle.
-
A broad nutrient spectrum
Nitrogen, potassium, calcium, iron and a range of trace elements — from one natural source, not a synthetic blend.
-
Highly concentrated
Diluted 1:400. One litre makes up to 400 litres of feed, so a little goes a long way.
-
Naturally derived
Made from certified Latvian sapropel — a freshwater lake sediment laid down over thousands of years.
-
Registered & labelled
A registered Group 2 organic liquid fertiliser: Act 36 of 1947, Reg. No. B6628. Used strictly per the approved label.
-
Low application rate
Applied at 1–2 L per hectare at the registered general-use rate, or 30 ml per tree — gentle, low-dose feeding.
-
Tank-mix friendly
Compatible with mineral fertilisers and all common irrigation and spraying systems.
The fix
One bottle. A broad spectrum of nutrition.
SaproGro™ is a registered organic liquid fertiliser made from freshwater sapropel. Diluted 1:400 and applied at low rates, it feeds your plants a broad range of naturally occurring macro and micro nutrients — from a single natural source.
01
Where it comes from
Most feeds are blended. SaproGro comes from one source.
Most liquid feeds are manufactured blends of separate ingredients. SaproGro™ is different — it is drawn from a single natural material, freshwater sapropel, which already carries a broad nutrient profile.
SaproGro™ is made from sapropel, a freshwater organic sediment laid down over thousands of years. It naturally contains organic matter, a broad mineral profile and a range of trace elements — delivered to your plants in a single registered fertiliser.
What's in it?
In addition to the basic macronutrients — nitrogen, phosphorus and potassium — sapropel also contains a wide range of trace minerals essential to plant growth and development. These include calcium (Ca), magnesium (Mg), iron (Fe) and sulfur (S), which support photosynthesis, enzyme activation and protein synthesis.

A broader story
Sapropel is an ancient freshwater organic deposit — not a single-source marine extract or by-product. SaproGro™ contributes a naturally broader composition profile to a regular soil-care routine, at low application rates.

From the garden
Why growers choose SaproGro.
SaproGro has become part of my regular garden routine. It’s easy to mix and apply, a little goes a long way at the 1:400 dilution, and I like that it’s a registered organic product from a single natural source. I’ve been using it across my whole garden and I’m glad I made the switch.
I started using SaproGro on my garden in Ras Al Khaimah. The concentrate goes a long way, it’s simple to apply through my normal watering, and I appreciate knowing exactly what’s in it and where it comes from. It’s become a regular part of how I look after my garden.
