...Much of the N in the gliricidia leafs and litter 192 kg ha–1 is rapidly mineralised when the gliricidia fallow is slashed and becomes available to the succeeding crop Hartemink and O’Sullivan 2001 ....

...Important amounts of alkaline nutrients like K or Ca supplied by litter, can change the soil conditions as fast as 24 weeks, which is important for the growth of some crops (Hartemink and O’Sullivan 2001)....

...A similar dynamic of decomposition has been observed in other important agroforestry species like Gliricidia sepium, which virtually stops decomposing after 4 months, when relative lignin content are elevated, exceeding 18 % (Hartemink and O’Sullivan 2001)....

...It is hard to estimate whether allelopathic effects influenced the sweet potato yield in our experiment, although the polyphenolic content of gliricidia leaves was indeed much higher than that of piper or imperata (Hartemink and O’Sullivan, 2001)....

...However, imperata biomass returned less N to the soil, and vine biomass was lower due to the slow decomposition of the biomass and the N immobilization (Hartemink and O’Sullivan, 2001)....
