Natural fertilizers are organic materials that enhance soil fertility and promote plant growth without the use of synthetic chemicals. Common examples include compost, manure, and bone meal. These fertilizers provide essential nutrients like nitrogen, phosphorus, and potassium, which are vital for healthy plant development. Using natural fertilizers can improve soil structure and increase its ability to retain moisture. They also support beneficial microorganisms in the soil, which help break down organic matter and release nutrients. This sustainable approach to gardening and farming can lead to healthier crops and a more balanced ecosystem, benefiting both plants and soil life.
