Fertilizer and seed can both be broadcast. When seed, for example, is broadcast it is spread by handful or by a spreader as evenly as possible over the soil. For best results, it is usually most effective to prepare the soil beforehand. When seed is light or small, mixing it with sand can make even distribution easier. After the seed is broadcast, water it gently; you might also need to rake soil lightly over the seeds, depending on the variety.
