L&#8217;activitat dels microorganismes descomponedors t\u00e9 un paper clau, ja que la seva pres\u00e8ncia i efici\u00e8ncia depenen de les condicions ambientals. Factors com la temperatura, la disponibilitat d&#8217;oxigen i la qualitat del material vegetal tamb\u00e9 poden accelerar o alentir la descomposici\u00f3, influint en el cicle de nutrients i la fertilitat del s\u00f2l.
