1). the main health issue is E Coli. In recent years there have been many vegetables sold to the public which have caused the outbreaks E Coli. Most of the public outbreaks have occurred in lettuce and tomatoes. All backyard gardeners should especially beware of placing manure on carrots, beets, turnips, and potatoes.
2). Manures will burn the roots of growing plants, especially chicken manure. Chicken manure is high in ammonia. Ammonia will burn the roots. It will also burn the leaves and the stems if allowed to touch.
3). Nitrogen is very slow to release in manures. Nitrogen is usually not available until after the first year it hits the soil. At that time only 50% is released the first year, 25% the second year, and 25% the third year.
4). Manures are very high potential for weed seeds. Weeds can be a major problem when applying horse or cow manure.
5). Salt build-up in the soil over the long run. The results can be drought like conditions and root damage. Plants/trees will be subject to diseases and insect problems. This will result in smaller crops and sometimes death of your plants/trees.

Controlled contents and releases are reasons why fertilizers can be better than manures. Fertilizers have to comply with application, labeling and proportion requirements. Plant and soil enrichment programs offer pathogen-, pest-, weed-free, slow-release applications that will not be guaranteed by manure (that is not composted).
Farmers add manures and fertilizers to the soil to replenish nutrients that are essential for plant growth. Manures provide organic matter and nutrients, while fertilizers supply specific nutrients like nitrogen, phosphorus, and potassium that may be deficient in the soil. This helps promote healthy plant growth, increase crop yields, and maintain soil fertility.

because fertilizers are rich in nutrients
Farmers often prefer to use chemical fertilizers over manures because chemical fertilizers provide nutrients in an easily accessible and precise form, allowing for better control over nutrient levels in the soil. Additionally, chemical fertilizers are typically cheaper and more convenient to transport and apply compared to manures. However, manures can provide additional benefits such as improving soil structure and increasing organic matter content in the long term.
the plants grows well and it will not last long after the yield
H. V. Garner has written: 'Manures and fertilizers'
Fertilizers are preferred over manures because they provide nutrients in a precise and concentrated form, allowing for better control of nutrient levels in the soil. Fertilizers are also easier to handle, transport, and apply compared to bulky manure. Additionally, fertilizers have a faster nutrient release rate, providing quicker results in terms of plant growth and yield.

Fertilizers and manures used on plants include Bone meal, Compost, Rock phosphate, Alfalfa meal, Feather meal, Liquid kelp, and many others.
Fertilizers and manures are added to soil to provide essential nutrients like nitrogen, phosphorus, and potassium that plants need for healthy growth. These nutrients help plants to develop properly, produce higher yields, and resist diseases. Manures also improve soil structure and increase its organic matter content.
