As we know, the mineral cycle is important for balancing in ecosystem.

1. MINERAL CYCLE Q&A
1. What do you think is the function of effective microbes, EM?
 I think the function of the Effective Microbes or Microorganism (EM), is to increase
the microbial diversity of soil ecosystem. Also, it is beneficial as the uses of it can
enhance the crop yield and biomass, then can make better quality compost.
2. During composting, what are the types of gaseous released to the air?
 Methane, CH4
 Carbon Dioxide, CO2
 Ammonia, NH4
 Nitrous Oxide, N2O
3. Could you list all the advantages of good mineral cycle management in the
farm?
 Improve soil structure
 Reduce the need of fertilizers and the feed from outside the farms
 Transfer of elements from one location to another. For example, the soil contains the
nutrients or minerals, then it transfer to the crops, and the animal like cattle eat them,
next, the crops inside the cattle digest and become faeces/ dung. The dung become
biofertilizers to the soil ecosystem. Then, it repeat and repeat again.
 Save costs because we don’t need use chemical substances to obtain fertilizers.
