Fertilisers

A fertiliser is a natural or synthetic, chemical-based substance that is used to enhance plant growth and fertility. Fertilisers may also enhance water retention and filter any excess liquid, hence enhancing soil effectiveness. Rolfes Agri has 8 different groups of fertilisers, each with their own products as listed below.
