Good luck

thank i have look at the link and find what i was looking for. thank

Aduol, this question is good however the answer can not be precise given that the levels of nutrients in the manure depend on various factors some being  the type of the feed/fodder the animal consumes, the management (handling) of the manure at farmstead among others. So much as you will have a universal data from various research studies yet they will just give you the inference of where the data comes from but the truth of the matter is that if you are working on a project that deals with that material it is good to do your own analysis to be precise. Test if you want just for indication may be the data available can suffice. However I would advice you to get manure analytical data from where you are coming from or close to where you are because I believe the main factors that influence the manure in a locality can be the same so you are likely to get more or less info that suits your condition

Arvind, thanks for sharing the info, it is useful in some cases yet not so much in the context of some areas. The organic materials vary a lot depending on the management thus even the pdf document you shared highlights that ".....They also vary greatly for a given organic fertilizer. For example, as the table on the following three pages shows, the nitrogen in raw bone meal ranges from 2 to 6%, and the phosphorus from 15 to 27%. Differences reflect variations in the age of organic material, its decomposition rate, application method and timing, incorporation time, time exposed to the elements (rain, sun), the percentages of organic matter and water the material contains, carbon-to-nitrogen ratio, microbe population, and soil type. Values for manures vary according to time of year, time in the open air, percentage of added straw, and rate of incorporation. The speed of release shown in the table indicates how quickly nutrients are made available to plants....."  So the scientist who asked looks like is based in Kenya, so the situation in Kenya in terms of manure management may differ from what you shared which looks like the data is from the States. It would have been convenient if he got at least data from Kenya which will reflect some how the real situation where the data could be applicable.

@ Kenneth,

You are perfectly correct.  From the point of excretion, nutrients in manure undergo rapid transformation.  Especially, for Nitrogen.  Gaseous losses of N as NH3 can be substantial, depending on the way manure is handled (until applied to crops).

An estimate

Goats manure contains 3%N, 1%P, 2%K

Cow manure contains  0.5%N, 0.2%P, 0.5%K

I will advise Mr. Athuai to strictly adhere to Dr. masuki's submission and not the values quoted on Arvind singh's shared facebook article. Nutrient composition of animal manure varies from location simply because of differences in environmental conditions, type of feed/feeding regimen, animal management practices, handling/disposal of manure, all these listed factors significantly influence your manure nutrient composition.

Some fascinating responses on the issue..Here is a very informative piece of work, hope it will be liked...

Effect of composting on the extractability of plant nutrients in organic wastes is essential for their recycling in sustainable soil fertility management. Therefore, an experiment was carried out to determine the concentrations of total C, total N, extractable P, K, Na and B in five types of fresh and composted manures (namely buffalo, camel, cow, goat and poultry). Laboratory results showed that the extractability of elements varied considerably with the type of composted manure. Total C varied in the order cow > goat > buffalo > poultry > camel while total N was in the order buffalo > poultry > cow > camel > goat. Total C, total N, extractable K and Na decreased with composting, whereas extractable P and B increased. Goat manure had higher pH and EC values than cow and poultry manures whether in fresh or composted samples. A marked increase in the EC value was observed in composted manures, whereas pH was reduced with composting.

Dear Aduol,

Although NPK contents of cow and goat manure varies with several factors as stated by Kenneth Masuki, you may use the following average values of N, P and K for comparison of the two animal manures:

Cow manure: 0.6%N, 0.2%P, 0.5%K

Goat manure: 0.7%N, 0.3%P, 0.9%K
