does anyone have an idea of how much protein is typically found in cow manure?

There are some nitrogen compounds though that are useful as plant nutrients. If you particularly want to increase the nitrogen content of your soil bird manure (chicken, turkey, pigeon, etc) has much more N compounds than cow but be careful as it will burn your plants when fresh or if applied too heavily, whereas cow is not likely to. http://www.primalseeds.org/npk.htm David |

Andy comments If you're using it as fertilizer for your garden, be aware that unless it is really composted well, the hundreds of undigested seeds in it will keep you busy weeding for years. I have mixed feeling about cow poop, and might suggest using bird poop, if you have access to it, instead.... Andy in Eureka, Texas |

Those complex substances may be food for organisms that do eat (heterotrophs) like cows and us. The inputs we are interested in, NPK and other elements, are often loosely called "plant food" which can be confusing in comparison with animal nutrients such as protein, carbohydrates etc as the two are not similar classes of substances nor do they have the same role in metabolism. Gardening terminology is also loose in talking about inputs as elements when to a chemist none of them are present in the form of elements but as compounds and molecules. This leads us to the case of N (nitrogen) as a plant input which is what I think you were asking about. Although it is four fifths of air plants cannot absorb N directly as nitrogen gas is a molecule of two atoms (N2) and that molecule is extremely stable and chemically inaccessible to the plant. So plants need some help to absorb N. This can be from microbes that fix nitrogen, such microbes can take in N2 from the air and produce useable N compounds. Often such are symbiotic with plants as in legumes. Plants can also get N as compounds as part of synthetic fertilisers, manures and composts, and from rain during electrical storms. This is why the N component of manures in its NPK value is of interest not the protein content. descends soapbox If this was not the point of your question ask and I will try again. David |

But I agree with your summation. IF I ate any of the cow poop I put on my plants or considered the poop to be human 'food', I might want to know it's protein content. Or if one or more of our cattle were ill, I may be interested in protein passed in the animal's faeces. When it comes to cow poop I use on my plants, however, I am only interested in the NPK of the poop. (And I too wondered if the OP really might have meant to ask about the N content of cow poop. But that was not the question asked even though asking that question of other gardeners would make sense whereas asking about protein didn't. Given how many trolls we've had here in the past who knows what prompted the OP to ask such a question.......) |

The ecology of the soil encapsulating the life and death cycles in the microorganisms, as well as their symbiotic relationships with the garden plants is what nurtures plants naturally (think slow release). One of the problems with chemical fertilizers (chemferts) is that they are water soluble. Clay in the soil will mitigate this to some extent by ionic bonding, but, by and large, the the chemferts get washed away to become someone's else's problem (blue babies, ocean dead-zones). what is annoying about much of the extra nitrogen problem is that it is largely preventable. songbird |

David ascends soapbox Uh, you forgot the amino acids that come from micro-organisms, which is what organic gardening is all about, i.e. the feeding of micro flora and fauna. descends soapbox That's true but the context was inputs not stocks. Once present the microflora act as a storage and exchange medium but the OP cannot feasibly add microflora to his soil as a source of N for the whole community. D |

What are you on about? Are you looking for the fate of the applied NO3-, or what? nitrogen isotopes used in studies of actual nitrogen uptake by plants. yes, the fate of applied nitrogen compounds, but actual studies of tagged compounds using nitrogen isotopes. i've come across only one reference so far in my readings and was wondering if anyone else here had come across any other studies of this type. Ammonium ions are positively charged and therefore stick (are sorbed) to negatively charged clay particles and soil organic matter. The positive charge prevents ammonium nitrogen from being washed out of the soil (or leached) by rainfall. In contrast, the negatively charged nitrate ion is not held by soil particles and so can be washed down the soil profile, leading to decreased soil fertility and nitrate enrichment of downstream surface and groundwaters. yes, but this is different than what i am asking about.

Especially with the implementation of organic farming methods. .... songbird |

I've heard that people use isotopes for these kinds of experiments. Hmm. Bit tricky that. Natural Nitrogen (N) consists of two stable isotopes, nitrogen-14, which makes up the vast majority of naturally occurring nitrogen, and nitrogen-15. Stable huh? Well they're out. ah, but that is ok, just that if most natural nitrogen is N14 then you use a high portion of N15 and then track how much of that gets adsorbed. this must be what the experiment i saw in passing did because they didn't say anything about it being difficult or very short term. or they were using other atom isotopes for tracking... can't say for sure. Fourteen radioactive isotopes (radioisotopes) [radioactive! That's more like it] have also been found so far, with atomic masses ranging from 10 to 25, and one nuclear isomer, 11mN. All of these radioisotopes are short-lived, with the longest-lived one being nitrogen-13 with a half-life of 9.965 minutes. Nine minutes? You'll have to be quick about your experiment ;O)) All of the others have half-lives below 7.15 seconds, with most of these being below five-eighths of a second. Oh, how the time flies! heh, good to know. songbird |
