Why is mulch compost not infectious?
Composting plant residues is a safe and scientifically validated method for eliminating plant diseases. During decomposition, microbial activity generates heat—often reaching 55–70°C (131–158°F)—that destroys harmful fungi, bacteria, and nematodes. Beyond this thermophilic phase, compost becomes a living shield thanks to beneficial microorganisms. Species such as *Bacillus subtilis* and *Pseudomonas fluorescens* produce antibiotics and enzymes that suppress pathogens, while *Streptomyces* (actinomycetes)…
