AN OLD MANURE DAM
WHAT TO DO?

PROBLEM:

A leading pig farmer has a problem with his manure dam (6000m). He is looking for ways to empty the dam and hopefully to use the contents either on his fields or selling it as fertilizing compost.

OPTIONS:

  1. The Negative solution (higher costs in labour, energy, fertiliser, etc. and less income)

Brings little income.

Will burn everything that is growing, pollute the ground water, destroy the micro-organisms

in the soil. Animals do not enjoy grazing on this land and also the grazing has poor

nutritional quality.

2. The Positive Solution

selling natural, high quality fertiliser or using the compost himself and no need to buy

chemical fertilizers .

*Since most farmers in South Africa do not have the means to distribute liquid fertiliser onto their fields

(tank on trailer behind tractor), it might be advisable to compost the contents of the dam and bring it out

with a tractor, labourers, forks, etc.

HOW TO GET FERTILISING COMPOST FROM MANURE DAMS

  1. Situation:

Often pig farmers let their manure through straw bails to catch most of the solids. These solids are sold or used by the farmer. The liquid with the remainder of the solids flows into the dam. After years the dam is partially filled with sediments, some liquid and above that the solids. Over- flow of liquid in adjacent dam mixed with rain or other water (maybe waste or grey water from the house etc.).

2. Composting the Dam Contents :

Use for the composting of average manure 1kg Penac K 1541 per 100m. In case of obnoxious manure go up to 1.5 kg/100m - 2 to 3 months later compost should be ready. Then go in with front loader or similar device and take out the fertilising compost for the use you choose. Since the dam is so large and most probably no agitator available - check if sediments and manure are mixed - if not premix it before bringing it out.

 

3. Gain:

healthier animals, higher quality meat (leaner), milk etc. all these bring much higher

income.

HOW TO PRODUCE LIQUID FERTILISER FROM PIGS

Use Starter Kit 1141 1 kg per 100m - to 1.5 kg if problematic manure.

If too difficult to disperse beneath the solid layer of the dam - apply 2/3 of the G over the inflow into the dam or even better the manure collector chamber. 1/3 of the G must be applied directly to the dam liquid.

IMPORTANT:

    1. If inflow of manure continues while conversion takes place, add small quantities of

Penac from time to time. (100g/100m)

2. Once the process is completed and fertilisers as well as liquid fertilisers are stored

for a longer time (from approx. 2 to 3 months on) then add from time to time G

100g/100m to keep the micro organisms active. This way storage is no problem.

 

IN CASE OF AN OVER- FLOW- DAM

Treat the dam with G 1141 or W Wastewater 4541 1kg/100m.
