The existence of the Billinghamplant and others likrit, suggest a very substantial market for their nitrogencontaining fertilizers. Why is this so? We have known for many years these essential nutrients. These
nutrients include nitrogen, phosphorous and potassium, which are particularly important in promoting the
growth of agricultural crops, as well as a number of other elements some of which are required onlyinvery
small quantities. These include calcium, magnesium, sodium, sulphur, copper, iron, zinc, manganese and
boron. Adding manure and compost to the soil is one important way of returning to the soil some of the
nutrients used by plants as they grow. However, the intensive cultivation of crops developed to feed a rapidly
growing world population often removes nutrients from the soil more quickly than they can be replaced
by natural means. Artificial fertilizers are therefore added to the soil to make sure that they can continue
to support the growth of crops. Artificial fertilizers may also, of course, enable plants to be grown on land
previously unable to support the growth of crops because it lacked some, or all of the essential nutrients.
