Many areas of the south-west of the state are characterised by soils with sandy surfaces ranging from deeps sands to sands over clays, and soils dominated by ironstone gravels. Some soils are sticky, others will not stick together at all, and others feel "doughy" or "spongy". In warmer climates, like Australia, chemical weathering is more common. An ecosystem includes all the living things (plants, animals and organisms) in a given area, interacting with each other, and with their non-living environments (weather, earth, sun, soil, climate, atmosphere).

If your soil is alkaline, it means it has a high pH. Western Australia covers a vast area with a wide range of soil types. Mineral or skeletal soils exist over much of arid Australia that contain virtually no organic content and have developed little depth; they may consist merely of a rough mantle of weathered rock.

If your soil is sandy choose native species such as grevilleas, banksias, hakeas or acacias that can extract nutrients from poor quality soils. If you want to grow plants that need more fertile soil, add well-rotted animal manure, compost or leaf litter to improve nutrient levels. Workers build a plaster-like layer over their feeding areas to protect themselves from the environment, unlike other termite species which tunnel inside the wood to feed. suits many Australian native plants. The soil that is found in the Tropical grasslands is either Porous or Laterite and is acidic. Soil – relative particle sizes Soils are usually classified as Soils in the northern parts of the state, although variable, are often characterised by oxides of iron giving them a characteristic red colour. Yet appearances can be deceptive. Added to sand and clay, in soils, are various other minerals such as limestone, sulfur and the like. Abnormal moisture conditions. Soil preparation involves the addition of organic matter, a small amount of blood and bone to the soil and moisture. Australia's soil is composed of several different types, each distinguished by its consistency, primary materials, surrounding environment and climate. The Australian soil-classification system is specifically formulated to differentiate between the many types of dry soil found on the continent. Soils are a fundamental natural resource, and are the basis for all terrestrial life. Luckily there are a number of Australian native plants that are either native to, or are tolerant of, calcareous or alkaline soils. There is no easy method to lower the pH of highly alkaline soils.
