Question

why is cow waist good for farming with?

Doesn't it contain bacteria?

Is human waist also good for farming?

Answer 1

when cow waist breaks down it fertilizes the soil making it better to grow plants in because of the nutrients that come from inside the body of the animal. i dunno about human waist.

Answer 2

Cow waste, or manure, is good fertilizer with most of the essential nutrients needed for plant growth. It does contain a lot of bacteria, some beneficial  and some harmful to your health if used improperly. The best way to use any manure is to compost it first. Always wash well any vegetables harvested from land that has been fertilized with animal waste. This will include almost all organically grown produce, also for any produce purchased from stores, as you don't know how it was produced.

Human waste can also be a good fertilizer, but comes with a lot more risk, it can contain a lot more harmful bacteria, and must be used more carefully than other animal waste. Human waste collected from municipal sources may contain a lot of other waste products that could be harmful to the soil as well as plants.

Answer 3

Plants grow and incorporate all the nutrients they need from the soil. Roots frequently go quite deep to dredge up those nutrients as they head down to the water table. Grazers come along and eat those plants. Those nutrients cycle threw their bodies, decomposed by bacteria in their gut. Those now partly digested plants and the liquid waste from this animal are excreted back onto the soil. This waste may be again picked apart by animals, and will eventually be further degraded and spread mechanically, by stomping and rain and dessication/ wind (whatever), exposed to soil bacteria, etc. It is that cycle we copy when farming by incorporating animal wastes and other composted organics, back into the soil. These waste products are very active and that level of activity changes from hot gut bacteria to a composted collection of soil flora of second level bacterias and fungi. Human waste is different in that humans eat differently than cellulose based ruminant foods, like grass. Our waste composts similarly but we have the disadvantage of being higher up on the food chain and getting more toxic materials like heavy metals. Also, some pathogens (host specific to us) can possible pass back to us so great care needs to be taken to insure adequate composting and complete cleaning of all foods upon harvest. That's the short of it.

Answer 4

Manure.

It is supposed to be composted before using and supposedly that kills bacteria.

The truth is that modern cattle production has meant high protein feeds and cattle now have bacreia in their guts that they never had before like E. coli.
