I agree completely with Kris Ringwall, Beef Specialist, NDSU Extension Service. For to long manure has been looked upon as a waste product and an environmental hazard. Manure, not only is it a soil ammendment, it also supplies back to the soil nutrients that are available to plants, and organic matter so necessary for the soil. How many times have farmers been encouraged to get rid of their manure and buy fertilizer. Why not use manure effeciently as a source of nutrients and supplement with fertilizer when and if necessary.

The word waste should not be allowed to be used. In Africa, the technology of harnessing manure to produce energy for lighting and as a fuel for cooking in poor small-scale households is documented. The slurry arising from livestock operations is passed through appropriate biodigesters to enable this. The type of digester used has been modified such that even the very poor farmer is able to afford the same. It is because of the opportunity seen in the animal manure that efforts of this nature have been accelerated. We hear that other countries, that are developed, have started programmes to harness the energy in manure! Such a by-product shouldnt be looked at as a waste.

It is about time that someone picks up this very important issue and what he writes as also the comments are absolutely true - however valuable points need still to be mentioned:
Manure is anaerobe - thus it usually contains as a negative aspect parasites and pathogenic bacteria - and as a positive point the so very important N (Nitrogen) which is needed so badly in agriculture. I must not forget that in many countries newly born animals do still get
antibiotics mostly seen as a growth hormone - this is insane. Luckily at least the EU has outlawed antibiotics in this form but only allow same in case of absolute need when the animals are sick.
1) Just imagine - if your mother would have given you antibiotics from the start you would never have been able to develop a strong immune system - we would b e like zombies - same goes for the animals. The result is that they need much more medication during their life than they would otherwise. This besides so many other negative aspects as e.g. higher costs again increases the contamination of our environment.
2) The animals partially expel these substances including antibiotics through their pings, the manure. These then (antibiotics, parasites and pathogenic bacteria) infiltrate into soil and plants and from there into the groundwater polluting our most precious water resources.
From a pure human point of view (which of course goes for the animals too only that they dont live as long as we do) more and more people are becoming resistant to antibiotics as these residues build up in their body from the water they drink and the plants they eat. Throughout our planet scientists are searching for new life saving new antibiotics to break the resistance.

Are there any environmental friendly cost effective solutions?

Yes - what I am stating here is based not on hearsay but on own experience over more than 10 years and the experience of my colleagues in many countries - we all consult and work with the same natural technology developed in Germany in the 1970s/80s.
a) It is a proven fact that due to proper composting of the manure antibiotic residues, foot and mouth disease, swine fever etc. etc. become eliminated hence no antibiotics etc. in water, soil and plants anymore - a huge progress.
b) But it goes much further: With this composting process the N is bound in the compost and thus later on slowly released to the soil. Where manure is not collected as e.g. on pastures once or twice a year the manure is dispersed by a harrow, the pasture is then sprayed with the additive used for the composting - the effect is that the life forms in the soils multiply in an unbelievable rate breaking down the manure, bring it back into the soil and the pasture grows vigorously and healthy - replacing the need for chemicals fertilizers and thus reduces the input costs dramatically and improves the fodder quality.

The contents of manure dams, lagoons or pits which usually are considered as a problem waste as it is very difficult to empty them.
A two dam system is ideal. The contents become without using agitators liquid and aerobic, non smelling with high N and very high in resonance energy - and ideal natural organic fertilizer that can even be sprayed onto the plants.

A great side effect - no fly breeding and no rodents anymore - they only go to anaerobe sources never to aerobic conditions.

With these undertakings we not only heal and protect our environment but we also strongly reduce farming costs.
