Cleaner, cheaper ammonia: Cheaper fertilizer

Source: Science Daily

Ammonia — a colorless gas essential for things like fertilizer — can be made by a new process which is far cleaner, easier and cheaper than the current leading method. Researchers use readily available lab equipment, recyclable chemicals and a minimum of energy to produce ammonia. Their Samarium-Water Ammonia Production (SWAP) process promises to scale down ammonia production and improve access to ammonia fertilizer to farmers everywhere.
