How quickly do our lime-sands work locations
Aims

To determine how quickly our lime-sands work.

Key messages

• 3t/ha Little Sahara limesand will increase the pH in the top 5 cm of soil within 6 months and the effect will last for 4 years before re-acidification occurs

• It can take up to two years to get a pH change down to 10 cm in the soil profile

• Maintain surface pH above 5.5 to minimise risk of sub surface acidification.

Soil amelioration

The Lime sand treatments are described below:

  • Little Sahara lime sand applied at 3 t/ha. This treatment was replicated 3 times
  • A single replicate of Emu Bay limesand applied at 3 t/ha. This product was ground to achieve fineness comparable to the Little Sahara product
  • A single replicate Calciprill applied at 400kg/ha. Calciprill is a commercially produced ground and pelletised lime product. Calciprill recommends an application rate of 100kg/ha will increase pH by 0.1 unit. Thus 400 kg/ha of Calciprill was considered comparable to an application of 3t/ha of local lime sand
