Fertilizer sprayers are tools used to apply liquid fertilizers to plants and crops. They help distribute nutrients evenly, promoting healthy growth and maximizing yields. These sprayers can vary in size and design, from handheld models for small gardens to larger, tractor-mounted versions for extensive agricultural fields. Typically, fertilizer sprayers consist of a tank to hold the liquid fertilizer, a pump to create pressure, and a nozzle to disperse the solution. Proper use of fertilizer sprayers ensures that plants receive the right amount of nutrients, which is essential for their development and productivity.
