After winter the wheat has not grown much more, so in the Springtime the Farmer spreads a Nitrogen fertiliser.
Then between now and April the wheat is sprayed (to prevent nasty diseases growing on the wheat).
In April and sometimes in May or June, the wheat is spread again with a nitrogen fertiliser and if there has been a lot of rain it is sprayed again with fungicide.
An insecticide is also applied to stop all sorts of nasty little bugs getting at our wheat!
There is a lot of spraying going on!
