Inoculants are substances that contain beneficial microorganisms, such as bacteria or fungi, which are added to soil or plants to enhance growth and health. They help improve nutrient availability, promote root development, and increase resistance to diseases. Commonly used in agriculture, inoculants can boost crop yields and improve soil quality. These products are often used in conjunction with fertilizers and pesticides to create a more sustainable farming approach. Inoculants can be specific to certain crops, such as legumes, which benefit from nitrogen-fixing bacteria, or they can be general-purpose to support a variety of plants.
