Thekey difference between manure and compost是肥料通常是动物粪便，是牲畜耕种的副产品，而堆肥是各种成分的混合物，是不同废物的集合。
Manure and compost are important soil fertility enhancers. These materials can increase the nutrient content in the soil to enhance the growth of plants.

5.Summary – Manure vs Compost
Manure is the organic matter used asorganic fertilizerin agriculture and mostly contains animal feces. There can be other components in manure as well, such as compost and green manure. Manure typically contributes to the fertility of the soil and the total nutrient content of the soil. It can add organic matter and nutrients to the soil. The most common nutrient manure can add to the soil is nitrogen, which is used by soil bacteria, fungi, and other organisms in the soil.
In the modern days, we use three main classes of manure in soil management. These are animal manure, compost, and green manure. Animal manure is a common type of manure containing feces. The most common forms of animal manure include farmyard manure and farmslurry。农院肥料还含有植物材料，例如用作动物床上用品的稻草。这些植物材料还吸收动物的粪便和尿液。
When manure is in a liquid form, we call it slurry. It is formed from livestock rearing systems that are intensive. Concrete or slats are used for this formation. Manure from different animals have different qualities and compositions. Therefore, their uses are different as well. For example, manure coming from horses, cattle, pigs, sheep, chickens, turkeys, rabbits, and guano from seabirds have different compositions. This is because these animals eat various things. For example, sheep manure is rich in nitrogen andpotash。Pig manure has relatively low amounts of both. Since a horse typically eats grass and some weeds, their manure contains grass and weed seeds because they cannot digest seeds as cattle do.
Compost can be described as the decomposed remnants of organic materials, and it is a type of manure. Generally, compost has a plant origin but can often contain animal dung and bedding material. Therefore, compost is a mixture of different ingredients useful in improving soil fertility. Typically, compost is formed from thedecomposingplant and food waste, including recycling organic matter. This decomposition results in a mixture rich in plant nutrients and some beneficial organisms. These organisms include worms and fungal mycelium. Typically, compost can improve soil fertility in gardens, agricultural landscapes, horticulture, urban agriculture, etc.
The use of compost has various different benefits, including nutrient providing to crops, acting as a soil conditioner, increasing the content of the humic substance in soil, and introducing new bacterial colonies to the soil to suppress the pathogenic species in the soil.
At a simple level, composting generally requires the collection of a mix of greens coming from green waste and browns coming from brown waste. Greens come from plant parts rich in nitrogen, such as leaves, grass, and food scraps. Browns, on the other hand, come from woody materials such as stalks, paper, and wood chips.
