After you figure out what fertilizers you need for your garden or yard, you need to apply them properly. Proper application is based on the method and the timing.
You can broadcast fertilizers evenly across the soil. You can also till them into seedbeds before planting the seeds. These simple ways of fertilizer application can allow you to prepare the soil for the next planting season. To provide nutrients in concentrated amounts, you can band fertilizers in trenches in the root zones of plants. This is where the seedlings need the nutrients most. This method is particularly useful when adding phosphorus because phosphorus usually gets absorbed slowly yet is critical in seedling establishment. Side dressing fertilizers are effective when providing nutrients to already established plants in the middle of the season. Liquid fertilizers such as fish emulsion are created for foliar application that provides an immediate boost of nutrients during the growing season to fix previously neglected nutrient shortages.
If your garden is small you can spread the fertilizers by hand using a bin, bucket or some other small container. For larger areas, you can get a special spreader such as a drop or a rotary spreader. These tools are available online and at local garden stores. Rotary spreaders can cover large areas very quickly but not always evenly. Drop spreaders are better if you want to cover an area with uniformity, but there is a danger of fertilizer band overlap that can lead to salt issues and growth obstruction. You may want to consult with an expert like Jeffry Hill to find a solution that is right for you.
