By a “spreader” do you mean a manure spreader? If so it won’t work for fertilizer or seed.
You’ve got three different products, here, and each has very different qualities so each will require a specific piece of equipment.
For seed you can use a drill or a broadcast spreader. If your local soil conservation office has one then rent a drill from them. Drilling is generally superior to broadcasting as you will have less loss and better germination.
For fertilizer we order the product from our co-op and they include the use of a “buggy” in the price.
For manure we had a spreader as did most of my tenants. Right now we don’t so we have a “manure pile.” It’s been composting for some time now. The SCS office has a spreader so later in the winter I’ll rent it and take care of the “pile.”
For the seeder and fertilizer just rent them if you can. Call your Extension office and find out who has them. For the manure spreader it might make sense to buy one. The “estate” size units are OK but I’l look around for a used “real” spreader.
Good luck in your search.
