Producing chickens or eggs on land treated or contaminated with organochlorines (OC) is not recommended for domestic consumption or commercial purposes. Any land with a soil OC level of 0.10 parts per million (ppm) or more is regarded as a risk area for grazing livestock and consumption of soil.
The description of road boundaries for each Restricted Movement Zone (RMZ) are as follows.
To produce potatoes with high specific gravity follow good agronomic practices. Use high quality seed of the correct variety. Plant the variety at the right spacing and time of year. Apply nitrogen and potassium fertiliser to meet crop needs. Apply addequate irrigation.
The Animal Biosecurity and Welfare program within the Department of Primary Industries and Regional Development (DPIRD) manages evidence-based systems to maintain and verify our high animal health, food safety and animal welfare status.
Technology plays an integral role in ensuring our State’s agricultural sector remains profitable and sustainable.
A fertiliser program for potatoes growing in sandy soils must balance environmental risk with maximising returns. Coastal sands are naturally infertile and require higher rates of nutrients than loams.
Plants require trace elements in smaller quantities than macro nutrients but deficiency or toxicity can cause similar losses in yield and quality. Soil tests for trace elements in sandy soils are not as accurate as for macronutrients but can provide a guide.
Rainfall to date graphs show the amount of rainfall accumulated from the start of the grain growing season and can be used as a tool in the seasonal decision-making process.
Western Australia has many insect and mollusc pests (snails and slugs) that can affect the quality and yield of vegetable brassicas crops.
Globodera rostochiensis, golden or potato cyst nematode (PCN) and G. pallida, pale or white potato cyst nematode, pose a threat to the Western Australian potato industry.
