I have difficulty understanding how envirinment waikato can have any right to prosecute anyone for contaminating waterways when I understand they play a huge part in dumping lethal poisons such as 1080 into the water catchments I would love to see the graff boys video poisoning paradise on tv so the public can see what is really happening.

The soil bacteria best used, as a generalisation, require about a 12:1 carbon/nitrogen ratio for their cycles. which is about what green leaf/grass, most cattle manure, it can vary, are. Funny how that works out just right. If an animal does not chew off all the grass tops, growth continues well but some of the root system must die. Which is a big proportion of the plant residue you talk of. If excess nitrogen is not available for bacteria growth or not put on, the OM content of the soil can build up. In well mineralised soil, the plant is constantly sending a percentage of various sugars, in balance, down to the roots to feed the bacteria in exchange for the digestive ability of that bacteria to break down what the plant requires in other nutrients. The below surface cycle can increase OC faster than it is taken off the top.
Thus it is a simple management process in healthy plant/soil (one word) to quickly build up the percent of OM over the carbon lost/cycle. Forest floors can also build up a top soil over many years but well managed grasslands can do it quicker. The healthier the soil the deeper the roots.
Karl is correct that worms also have a symbiotic relationship with fungus and bacteria in their gut and in the break down of dead matter to the point that they can consume it and more the living soil around.

Reply to PBM Yes you are right it is Nitrous Oxide and this is formed from the Cycle working in the Soil which turns Nitrogen from the Air into Nitrogen that Plants can use to Grow . When the Soil becomes over loaded with Nitrogen this changes the Cycle instead of taking Nitrogen from the air through Legume Plants eg Clover and Bacteria. The cycle turns and starts to change the over supplied nitrogen in the soil into Nitrous Oxide which is then pushed out into our Atmosphere which we have to breath to sustain Life. This excess N20 is more harmful than CO2 and if we have to much N2 in our soils the Cycle and the Clovers and Bacteria start to shut down which then slows down Natures Natural process of sinking or storing CO2 in the Soil , This Sinking can be 3 times higher in Healthy Soils . So why are we then destroying what Nature Does Well . The Point I trying to make is Nature works very Good at what it does, if Man only would work with it instead of trying to control or manipulate what it does ,our Soils are made like they are for a reason and they have been around for Millions of years where we Man Kind has only been here for a few 1000 years (What a joke we are not Kind just Greedy to Nature) Add too much Nitrogen to our Soils and we Destroy them, slow down pasture production, breed sick stock and pass these problems onto Humans. THAT IS TRUE ! Earth Worms move up and down in the Soil and they come to the surface to feed on Dying and Decaying plant matter (Thatch) this is not green . As they tunnel through the Soil there Guts pass out 7 Times more Nutrients than when they started (Worm Casts)So yes we need the Little Buggersthis tunneling aerates the soil adds oxygen , helps with drainage, increases soil Temperture,takes Nutrients to Plant Roots faster than if they weren't there doing there JOB Little Darlings Karl Barkley

Karl Barkley,your comment " Look at Nitrogen 78.08% and a Green house GAS 310 times worse than CO2"???Nitrogen is not a Green House gas as you state! In fact it is non reactive. Therefore the 78.08 percent of atmospheric N2 you talk of does not effect GHG levels. This brings you comments no credibility.Also I thought earth worms eat green waste that usually contain around 4% nitorgen. So how is it that Nitrogen fertiliser now kills earth worms?Grant Lion...You are correct that OM is where soil Carbon is present. The largest form of this OM in may soil that I am aware of is plant residue on the surface then we go down to micron sized humus etc? How is it that these small particles store away carbon when htey are involve in the biological systems you talk of that a always cycling around?

Healthy Soils Equal’s Water HealthThe Great Carbon ConWe are having the Carbon pulled over our eyes. Is the Climate change due to Carbon or are there other more sinister gases which we breath that are causing Global Warming . Google what’s in the air we breath .We all breath in : Argon 0.93%, Oxygen 20.95%,Nitrogen @ 78.08% and Carbon dioxide @ only 0.038% such a small amount !So I ask the Question Carbon at so low a rate .038% why is this being targeted as the Source of all the Worlds problems . Look at Nitrogen 78.08% and a Green house GAS 310 times worse than CO2 and our intensified Farming practices are pouring on 10,000's kg of Nitrogen per year on to pasture that doesn't need it or either can't coup with it so that over 50% of applied N ends up in the Air we Breath as Nitrous oxide and the rest passes through our over supplied soils as Nitrates into our Water ways which we Drink. When the soil is over supplied with Nitrogen Nature Shuts Down and doesn't do it's job , Earth Worms die off and Bacteria changes when we loose EARTH Worms we end up with Very HIGH Counts of E-Coli in out Drinking Water and Food Chain . Lack of Large Colonies of Healthy Earth Worm’s Means Fertilisers get Locked up in the Soil so Farmers keep needing to pore more on to get, the same results as what Nature can give them for far Less Cost or Pollution . Earth Worm Cast’s gives your Pasture 7 Times more soil Nutrients than Chemical Fertilisers can . Other sources of Nitrous Oxide are also coming from burning of Auto Fuel’s in car’s etc.at what figure is this happening ? I want to know is Nitrous Oxide coming from the burning of Fossil Fuels greater than CO2 ?Wake up (is it Carbon) which is doing the Deed to our Climate or is it the Chemical Industries feeding our Farmers the Poison’s of there Mind's . Nature doesn't need all this added Nitrogen and Super Phosphates Acid based Fertilisers ,Won’t Grow Healthy Soils and Crop's or Live Stock ! Healthy Soils will store (Sink) 3 Times more Carbon than the Atmosphere can .So Why are We Letting them do it ?Email:email@example.com Karl Barkley

GR8 Programme 100% Pure , Well I wish OUR LOWER RIVERS were and it’s GR8 to see that the Media is finally Looking in to our Problem’s . What’s happening to our Soil’s and Water Ways are More Important to NZ as a Whole than Global Warming & Carbon Credits . I’ve been fighting for years now for Mother Nature and her Little helpers, the Earth Worm’s yes the Humble Earth Worm , working away under our feet in the Soil of our Gardens and More Importantly in our vast Agriculture Pastures, the most Important and over Looked Part of the debate over our Rivers and Water Quality. Is the Earth Worm’s - Microbes & Bacteria all in Balance working together in our Soils to make them healthy . If these are not there or they are all out of Balance because of all the Poison’s that are getting Poring onto our Farms .Then we can’t expect the water that is running off or through the Soils to be Healthy to Swim in or Drink ! We All Need Water Grant Lyon has some good points and I will add some more shortly . But I have a Big concern recently I presented a Submission to the Draft plan for Environment Southland , Councils Community Plan 2009 - 2019 . I asked for an independent study to be carried out into the use of (Urea) Nitrogen & Super Phosphate being used on our Intensified farms in Southland . As I am concerned at what harm they are coursing to our Pastures and Water Ways which flows onto Human and Stock Health? I‘ve got a reply which concerns me even more, as the Council who are supposed to be our Environment Council. Tell me that they considered my request but Declined it saying that this was outside the Councils Jurisdiction , especially with the financial constraints that Council is facing . Finance is got nothing to do with it, it’s about our Environment and what’s being done to it which is going to effect us all as we have to Drink Water to Survive .

There is a way to help clean polluted waterways and ponds. Bales of hay, these create helpful enviroments when they are left in the water, by releasing enzymes, we have seen these used to great affect. The pond I saw this used in was clean again within 3 weeks.The govt should make planting the edges of all waterways on farms mandatory practice, it works!.

I have to disagree with comments about whingeing environmentalists and the so called blame game - for over a year Greenpeace has been advocating for 'smart farming' or what's commonly known as biological farming - in which the soil is looked after - i.e. less inputs, better economic sense for the farmer and way less emissions into the atmosphere. As one biological farmer said to me - "we're dirt farmers really, it doesn't matter what you grow on top whether it's olives or cows. If your soils healthy you'll have a healthy crop." www.smartfarming.org.nz
