AGRICULTURAL LIME
The soil improver:-

Agricultural lime is Lake Preston Lime's most widely known and respected product. It has been used very successfully to improve the level of pH in acidic soils in the agricultural, horticultural and forestry industries for many years. Lake Preston Lime is an accredited lime supplier with LIME WA inc.

Lake Preston Lime's success is due to the crushing of the limestone rock and using a 2mm screen to provide a product that will give immediate as well as long lasting soil improvement.

Crushing the limestone provides a fresh new, multi facet surface on each particle that aids the breakdown of the product when weathering occurs to improve the soil condition.

We believe the crushing to be critical to allow these immediate and long lasting results in the field and are an advantage over lime sand, which has been weathered over many years before being loaded and used in agriculture.
To Quote The WA Agriculture Department:

“Soil acidity affects over two-thirds of Western Australia’s wheat belt and costs the farming community in excess of $100 million annually through lost production.

Many soils in Western Australia’s agricultural areas are naturally acidic. However, agriculture accelerates the acidification due to:

  • Leaching of nitrogen fertilisers,
  • Removal of produce such as grain, hay and livestock,
  • Use of legumes in rotations.
Soil acidity affects the availability of soil nutrients such as nitrogen, phosphorous and molybdenum and can lead to nutrient toxicity and deficiency.

The main cause of yield loss in Western Australia is from Aluminium toxicity. Aluminium begins to dissolve in soil at pH 5.5. The availability of Aluminium limits root growth making the roots short and stubby. The limited root growth can lead to nutrient deficiencies or drought symptoms of the crop. Some of the symptoms of soil acidification include:

  • Nodulation failure on legumes;
  • Deficiency symptoms of phosphorous, zinc and molybdenum;
  • Poor root growth with stubby roots and few fine root hairs;
  • Poor crop / pasture yields even in a good season and
  • Crops drought more easily because of poor root structures.
Lime is the simplest and most economical way to increase soil pH and decrease acidity. Lime should be applied at 1—1.5 tones/hectare every 7—10 years. If the soil pH is below 4.5, you will most likely have to apply lime twice within 5 years to lift the pH, then go to a maintenance liming regime.”
Lake Preston Lime has been operating under the LIME WA INC. Agricultural Lime Industry Code of Practice for several years. This Code was developed in 1999 by a group of concerned lime producers, in conjunction with the AFSA and Department of Agriculture, and assisted by Natural Heritage Trust funding.

As a LIME WA INC. accredited supplier, Lake Preston Lime is able to provide you with a Product Information Sheet presented in the Association’s standard format. This sheet contains up-to-date, accurate information about our product, which is tested at least twice in each season, according to set criteria at a Code of Practice approved laboratory.
