  1. they are probably better for you, being that the manure acts as a fertilizer the plant is probably healthier


  2. They are better,healther.The manure helps them to grow and gives them introgen and other things that help them.

  3. 'Manure is organic matter used as organic fertilizer in agriculture. Manures contribute to the fertility of the soil by adding organic matter and nutrients, such as nitrogen that is trapped by bacteria in the soil. Higher organisms then feed on the fungi and bacteria in a chain of life that comprises the soil food web.

    The word manure came from Middle English "manuren" meaning "to cultivate land," and initially from French "main-oeuvre" = "hand work" alluding to the work which involved manuring land.

    There are two main classes of manures in soil management: green manures and animal manures. Compost is distinguished from manure in that it is the decomposed remnants of organic materials (which may, nevertheless, include manure).

    Most animal manure is f***s — excrement of plant-eating mammals (herbivores) and poultry — or plant material (often straw) which has been used as bedding for animals and thus is heavily contaminated with their f***s and urine.

    Green manures are crops grown for the express purpose of plowing them under. In so doing, fertility is increased through the nutrients and organic matter that are returned to the soil. Leguminous crops, such as clover, also "fix" nitrogen through rhizobia bacteria in specialized nodes in the root structure.

    Other types of plant matter used as manure or fertilizer include: the contents of the rumens of slaughtered ruminants; spent hops left over from making beer.

    Manure has been used for centuries as a fertilizer for farming, as it is rich in nitrogen and other nutrients which facilitate the growth of plants. Liquid manure from pig/hog operations is usually knifed (injected) directly into the soil to reduce the unpleasant odors. Manure from hogs and cattle is spread on fields using a Manure spreader. Due to the relatively lower level of proteins in grasses, which herbivores eat, cattle manure has a milder smell than the dung of carnivores — for example, elephant dung is practically odorless. However, due to the quantity of manure applied to fields, odor can be a problem in some agricultural regions. Poultry droppings are harmful to plants when fresh but after a period of composting are valuable fertilizers.

    The dried manure of animals has been used as fuel throughout history. Dried manure (usually known as dung) of cow was, and still is, an important fuel source in countries such as India, while camel dung may be used in treeless regions such as deserts. On the Oregon Trail, pioneering families collected large quantities of "buffalo chips" in lieu of scarce firewood. It has been used for many purposes, in cooking fires and to combat the cold desert nights.

    Another use of manure is to make paper, this has been done with dung from elephants where it is a small industry in Africa and Asia, and also horses, llamas, and kangaroos. Other than the llama, these animals are not ruminants and thus tend to pass plant fibres undigested in their dung.

    In 2008, chemists at the National Institute of Standards and Technology (NIST) developed the first detailed chemical analysis revealing what processing is needed to transform pig manure derived 'crude oil' into fuel for vehicles or heating. Mass production of this type of biofuel could help consume a waste product overflowing at U.S. farms, but it will require a lot of refining. Their analysis is described in the 2008 issue of Fuel.

    Manure generates heat as it decomposes, and it is not unheard of for manure to ignite spontaneously should it be stored in a massive pile. Once such a large pile of manure is burning, it will foul the air over a very large area and require considerable effort to extinguish. Large feedlots must therefore take care to ensure that piles of fresh manure (faeces) do not get excessively large. There is no serious risk of spontaneous combustion in smaller operations.

    There is also a risk of insects carrying f***s to food and water supplies, making them unsuitable for human consumption.

    In 2007, a University of Minnesota study indicated that foods such as corn, lettuce and potatoes have been found to accumulate antibiotics from soils spread with animal manure that contains these drugs, and organic foods are most likely to contain these drugs because manure is often the main source of crop nutrients for organic food production.


  4. They should be MORE healthy because manure provides a number of nutrients which are useful to plants, chief among them nitrogen in the form of ammonia (NH3), nitrate (NO3-), urea and/or uric acid.  f***s is simply undigested and waste product, a lot of which is useful to other organisms.  It may contain electrolytes like potassium and phosphate which are crucial for plant growth and development.
