Lamotte 5012 Soil humus kit

$286.55

Lamotte 5012 soil humus kit. This kit is self contained and provides 50 tests for soil humus. As organic matter in soils is comsumed and broken down by microorganisms, nutrients are released for plant growth. Towards the end of this process longer lasting humus is produced and this can build up in soils. The important benefits of humus include binding that provides soil structure, water holding capacity and nutrient holding capacity.

Humus can be extracted from soil using an alkaline EDTA solution. The resulting yellow-brown colour can be compared against a standard colour chart to determine the amount in the soil. The Lamotte kit estimates humus on a 5 point scale corresponding to 1.5% to 8%. The instructions show how to interpret this level for agricultural soils, greenhouse soils and composts.

Apps Laboratories provides lab tests for reactive soil organic matter and moderately oxidizable organic matter that can be used alongside the humus test to show what is happening to the OM in your soil.
