All deposited N is consumed by sinks of nitrogen (immobilization and uptake), and only in this case CLmaxS is equivalent to a critical load of acidity. 

The work of Kimber (3, 1 4, 1 5), on phytotoxicity of plant residues, received comparatively little attention prior to the widespread adoption of reduced cultivation/plant residue retention in Australia during the past decade. Reports by farmers of reduced emergence of crops, often accompanied by chlorosis, were commonly attributed to nitrogen immobilization. Such data as were available related to phytotoxicity from residues of cereal crops.

The biological immobilization is a conversion of mineral nitrogen, in which it is bound into organic structures. It occurs as a result of the assimilation of mineral nitrogen by plants and by the rich microflora. The immobilization by plants is the most important form of nitrogen immobilization. 

The basic requirement for nitrogen immobilization by microorganisms is the presence and biological decomposition of organic matter with a low nitrogen content or with a high C N ratio. Under these conditions, the mi-...

Tracer studies conducted in flooded soils by Broadbent and Nakashima (1970) showed that immobilization values were intermediate between those obtained under aerobic and anaerobic conditions. Rice straw containing 0.47% nitrogen immobilized an additional...

In percentage of dry weight of wood. To obtain nitrogen immobilization values per ton of wood, multiply percentage figures by 2,000. This gives values of about S-25 lb. N for the various woods.
