Here are four common ways of applying fertilizers:
1. Broadcast Application: This involves spreading fertilizer evenly over the entire surface of the soil. It's often used for lawns and large fields, and can be done manually with a spreader or by using an agricultural aircraft.
2. Band Application: Fertilizer is placed in narrow bands alongside the rows of plants, typically during planting. This concentrates nutrients directly where roots will grow, making it more efficient than broadcast application.
3. Side-Dressing: This technique involves applying fertilizer alongside the rows of plants after they have emerged. It's often used for crops like corn and vegetables, and helps to provide supplemental nutrients throughout the growing season.
4. Foliar Application: Fertilizer is applied directly to the leaves of plants, allowing for rapid absorption of nutrients. This method is often used for micronutrients and quick-acting fertilizers, but can be less efficient than soil applications.
The best method for applying fertilizer depends on the specific crop, soil type, and desired nutrient levels.
