Agriculture and food security is facing pressure from the growing demand for cheap, nutritious, locally grown produce.
Some farmers are worried they may lose access to fertilisers and feed to help them meet the demands of growing populations and rising demand for their products.

There are few studies on farm chemicals and farming practices.
However, there are reports of farm chemical exposure and exposure to other chemicals including pesticides.
The Health Protection Agency (HPA) reports that some chemicals are not listed as hazardous to health but can cause serious health effects such as lung cancer and birth defects.
What we do know is that farming is associated with higher rates of health problems such as asthma, heart disease and chronic obstructive pulmonary disease.
What is in a name?
Many farmers refer to their crop as a crop name, which indicates how much of the crop it contains.
The name crops are usually defined by a common word such as maize, wheat, rice, sugar cane or tobacco.
In Australia, there is no national standard for the common name of a crop, so the government decides which crops to label with the common names.
These include maize, rice and wheat, among others.
Farmers are free to change crops, and the changes may be more drastic for some crops.
They may also use new names to differentiate their crops from others, such as ‘corn’ or ‘fertiliser’.
Some farmers may also change the names of crops, such the potato, but this may have negative impacts on the environment.
Farming is a complicated, environmentally complicated business, with more than one source of waste.
The most common source of pollution is fertilisers, which are a combination of pesticides and fertilisers.

Some of the biggest contributors to farm pollution are fertiliser and pesticide residues from farm machinery.
They can be found in the soil, water, air and soil runoff, in manure, on crop residue and in the manure on the farm.
Farm chemicals also come into contact with farm animals, including cattle, pigs, sheep, horses and goats.
Some farming practices have also contributed to the rise of disease, including improper hygiene, inadequate manure management, poor food safety, and inadequate irrigation.
Farmers can also be affected by diseases such as E. coli O157:H7, salmonella, P. aeruginosa and bovine tuberculosis.
Farmers should check what crops they are growing and how they are being grown to ensure they are complying with all of the requirements for farming in Australia.
