Fertiliser is a solution for growing crops. It makes plants grow better and faster. Thanks to fertilisers, worldwide, food production is on the rise. Fertiliser has been around since 1845. Now, 30% of the world's food production and 90% of the world's population depends on it. The main component for the production of fertiliser is urea, a product consisting of ammonia and CO2. Its high level of nitrogen guarantees a low (transport) price for fertiliser.
