Abstract: | The Adenosine triphosphate (ATP) content, dehydrogenase, phosphatase, urease, and β-glucosidase activity decreased after manure
amendment plus solarization (biosolarization), but they recovered after cropping, reaching levels higher than or similar to
those before the biosolarization. However, these biochemical parameters decreased and did not recover with time in the methyl
bromide (MeBr) treatment. Potential negative soil effects were assayed by measuring, ecotoxicity (Vibrio fisheri luminescence), germination index, electrical conductivity, and heavy metals content. Biosolarization did not negatively affect
these parameters, while MeBr application irreversibly decreased the germination index and ecotoxicity. Higher-quality pepper
production (extra and first class) were observed with biosolarization but not with MeBr, but no differences were found for
pepper yield. Biosolarization gave a Meloidogyne incognita (M. incognita) incidence similar to that of MeBr application. |
