Cacl₂ extractable N fractions and K₂SO₄ extractable N released on fumigation as affected by green manure mineralization and soil texture

A soil incubation experiment was carried out over 70 days (aerobic, 15°C) using a clay and a sandy soil produced by amendment with bentonite and quartz sand respectively. Fresh endive leaves were added as green manure (109 mg N kg⁻¹ soil). Controls without green manure were also included. Samples we...
