摘要：
Nitrogen mineralization from 15N labelled red clover (Trifolium pratense L.) and yellow sweetclover (Melilotus officinalis Lam.) plant fractions of three different ages (8-, 14- and 20-week old) was studied in an out-door pot experiment during 8.5 months. Individual plant fractions (leaves/stems/roots/flowers), 23 g dry matter pot-1 (corresponding to 7300 kg ha-1), were incorporated into a sandy soil. The net mineralization of N was measured as 15N recovery in spring wheat (Triticum æstivum L.), perennial ryegrass (Lolium perenne L.) following the wheat and in the soil mineral N pool.
