Manure and fertilizers are used to replenish nutrients in soil and promote healthy plant growth. Manure is an organic substance obtained from decomposed plant and animal waste that is added to fields to improve soil texture, increase friendly microbes, and replenish nutrients. Fertilizers are chemical substances made in factories that are also rich in nutrients like nitrogen, phosphorus and potassium but can pollute water sources and make soil less fertile over time. Both manure and fertilizers are beneficial for farmers but have advantages and disadvantages.
