Aglime and nutrients


Aglime increases availability of major nutrients nitrogen, phosphate and potassium by:

1. increasing nitrogen fixing in legumes and free living bacteria
2. increasing N, P & K release from organic matter through higher microbial activity
3. releasing phosphate from iron and aluminium
4. decreasing potassium loss from leaching


Aglime increases availability of minor nutrients sulphur, calcium and magnesium by:

1. increasing S, Ca and Mg release from organic matter through higher microbial activity
2. decreasing calcium and magnesium loss by reducing leaching
3. supplying calcium and magnesium


However, Aglime can decrease availability of trace elements

With the exception of molybdenum, most trace elements, especially manganese and zinc, may be less available to plants after liming. In some soils, particularly if trace elements are not regularly applied, deficiencies can occur as the soil pH increases after liming.


Plant sampling and analysis is highly recommended to ensure crops and pastures have sufficient nutrients to achieve high yields.


The information below is a guide to minimal levels (ppm) for trace elements in legumes or canola (Source Top Crop West).


Manganese 20-35ppm; Zinc 12-20ppm; Copper 2-5ppm; Iron 70-100 ppm; Boron 10-22 ppm.


We recommend farmers plant test and maintain trace elements above these minimal levels to achieve the best results from liming.


Note: Plant growth stage and plant weight can affect minimal levels. A consultant can help interpret your nutrient tests.


Acid Soils lead to inefficient fertiliser use.

Aglime helps fertiliser work = greater production and more profit.
