Organic fertilizers are derived from plant or animal sources and are often considered a more environmentally friendly option than synthetic fertilizers. They release nutrients slowly over time, reducing the risk of nutrient burn and providing long-term nourishment to plants. Examples include manure (from cows, chickens, or horses), compost, seaweed, worm castings, and bone meal. Aside from providing essential nutrients like nitrogen, phosphorus, and potassium, organic fertilizers also enhance soil structure and stimulate beneficial microbial activity, which can improve soil health and fertility over time.
