Carrier Material



For slurry

g 1041


Calcium Carbonate*



Starter for slurry

g 1141


Calcium Carbonate*

Stronger initial effect (pigs)

*Calcium carbonate: (98.1% CaCO3 + 0.9% MgCO3 = 99%)


Problems with slurry

Slurry treated with penac-g

Slurry is in a rotting condition (anaerobic)

Unpleasant ammonia and sulphur smell

Crusty layer as well as increasing layer of sediment present

Frequent agitation necessary

Scorching of plants and microbes

Possible loss of nutrients

Contamination of soil and water

Slurry becomes aerobic and decomposes

Good composting smell

Slurry homogenizes; formation of bubbles and blisters forming crust

Later sediments will dissolve

No scorching not even in hot weather

Nutrients are contained and become available to plants

Humus build up in the soil, no water contamination


First Use

Regular Application (min fortnightly)

1-1.5kg penac-g/100m slurry mixed in a bucket of water must go under the crust.

5g penac-g /LSU weekly or 1kg /100m

Application to canal system without a crust

Mix penac-g in a watering can or bucket, stir and distribute evenly over the canal. A better result is

achieved when 2/3 of the recommended amount is applied through the in-flow canal.

Application to canal system with a crusty layer

Numerous holes must be made through the crust. Apply the penac-g mixed with water by pouring it so that it gets under the crust.

In the dam

The penac-g and water mixture should be applied with the agitator running or where there is no agitator, poke a large pipe through the crust and apply the mixture, then if using a transporter, suck the mixture back, mix and re-apply to the pit. Large dams should be inoculated in various places.

In the slurry pit

Mix penac-g with water and distribute evenly. Repeat after emptying.


Observation is important!

The effectiveness of the penac-g is observable by blisters. Should no reaction occur due to contamination of the slurry (eg antibiotics) inoculate with live slurry. Important: using 1141 in slurry other than pig slurry for too long, can result in total composting and solidifying.
