Lime and liming / RHS Gardening

Lime and liming. Liming garden soil reduces the acidity of the soil by increasing the pH level. Plants can’t get the nutrients they need from soil that is too acid, and some materials such as aluminium can be at toxic levels in very acid soils. The pH level is a number that describes how acid or alkaline a soil is and from this it is ...

2011年7月1日  Application. Liming rates, traditionally expressed in terms of calcium carbonate, typically range 1,000 to 3,000 kg/ha. An agricultural limestone with a neutralizing value of 85 percent would have to be applied at 1,176 kg/ha to be equivalent to 1,000 kg/ha of calcium carbonate. The application rate also can be adjusted for fineness value.
