Regeneration, forest

The production of compounds which may act as allelochemicals is not restricted to higher plants. For example, Heisey, DeFrank and Putnam (41) have discussed substances produced by soil microorganisms which may have herbicidal activity. Bacteria may also mediate allelopathic activity in economically important situations such as forest regeneration (Line, personal communication) crop/weed associations ( ), and reduced cultivation systems where plant residues are retained ( ).

Due to increasing population pressure and new land use policies that prohibit deforestation and burning of primary forests, regenerating forest fallows are under increased pressure fi-om farmers. The fallows are being slashed and burned well before soil productivity has been recovered which results in rapid and...
