“…This implies that incorporation of labile organic matter particularly in Irabari, Kaninwathiga and Mutugu will be crucial so as to improve bacterial mediated decomposition (Ferris and Matute, 2003). The two decomposition pathways should be active and coupled in a healthy agricultural system (S anchez-Moreno and Ferris, 2018). The EI values in our study were similar among the eight regions as previously reported (Okada and Figure 3.…”

“…The CI and EI provide a useful tool for evaluating levels of soil fertility and nutrient resource availability (Ferris et al, 2001). The CI values <50% and >50% denote bacterial and fungal mediated decomposition pathways, respectively (Ferris et al, 2009;S anchez-Moreno and Ferris, 2018). In the present study, the CI values ranged from 39.99 AE 4.90 to 73.58 AE 17.41 indicating the occurrence of both bacterial and fungal decomposition channels across the eight regions.…”

“…In recent decades, one significant achievement is the development of a biodiversity perspective to assess soil health, which helps address long‐term sustainability challenges beyond a focus on only crop productivity (Lehmann et al, 2020). Nematodes are the most abundant and functionally diverse Metazoan and have been widely accepted as valuable indicators of soil health (Ferris & Bongers, 2009; Neher, 2001; Sánchez‐Moreno & Ferris, 2018). Indeed, nematodes are distributed in multiple trophic levels within the soil food web and link tightly with plants, microbes, and other soil organisms (Ritz & Trudgill, 1999; van den Hoogen et al, 2019; Yeates et al, 1993).…”

Plants act as ecosystem engineers playing fundamental roles in steering their surroundings, including soil abiotic and biotic conditions, soil organisms, and the complex soil food web they comprise. Trait‐based approaches have been considered a ‘Holy Grail’ in linking plants to ecosystem functions, but the mechanistic relationship between plant traits and the soil food web as an indicator of soil health remains poorly understood. We examined this relationship for 16 cover crop species differing in leaf and root traits in a field experiment where corn, Zea mays was the main crop. Based on functional traits, the cover crop species were categorized into two ecological strategies at either end of the resource acquisitive‐conservative spectrum. We investigated the effects of cover crop ecological strategies on corn productivity and soil health. We used soil nematodes as an indicator of soil health and analysed soil physico‐chemical properties and microbial community activities. We found that acquisitive cover crops supported higher soil resource availability, bacterial energy channels in the soil food web, and greater corn productivity than conservative cover crops. In contrast, conservative cover crops supported higher abundances of fungivores and omni‐carnivores than acquisitive cover crop, which reflected a more structured and complex soil food web, implying a healthier soil ecosystem. Conservative cover crops also increased corn productivity compared to the no cover crop control treatment. Synthesis and applications. Collectively, this work shows that cover crops with distinct ecological strategies had their own strengths to enhance ecosystem functions: acquisitive and conservative cover crops improved crop productivity and soil health, respectively. These results indicates that farmers and policy makers can make trait‐based choices in selecting cover crop best serving the local needs. This points to a win‐win solution for food production and ecosystem sustainability.

“…After 11 days, which is the period it takes for L. bethae egg to hatch, 5 g of tomato S. lycopersicum (variety: Money Maker) root galls were buried into each L. camara plant of all four aforementioned treatments. This was equivalent to 150 M. javanica females per plant, according to the formula of 1000 μg root galls containing 30 Meloidogyne females . After 62 days, when M. javanica was presumed to have completed a life cycle in the L. camara roots and had formed galls and egg masses, all the L. camara plants in all the treatments were uprooted, washed and inspected for the presence of M. javanica .…”

BACKGROUND Changes in plants induced by one species have indirect effects on interactions with other species, thus shaping their abundances. The root‐feeding beetle Longitarsus bethae released as a biological control agent for Lantana camara has established at a few sites in South Africa. Lantana camara plants infected with the root‐knot nematode Meloidogyne javanica often exhibit an increase in L. bethae abundance, suggesting that nematode‐infected plants could be enhancing the development of the beetle. This study investigated the interaction between L. bethae and M. javanica. RESULTS The study showed that galling by M. javanica occurred at the highest inoculation of 300 eggs of L. bethae per plant. Longitarsus bethae performed over twofold better on M. javanica‐infected L. camara roots compared with healthy roots, and 275 adult L. bethae progeny, with slightly larger body size, emerged from M. javanica‐infected compared with 167 adults that emerged from healthy plants. Fresh gall weight from treatments where both L. bethae and M. javanica were combined was 36% higher than that from M. javanica only, suggesting that the combination of both species induces more galling than the nematode does alone. The total biomass of plants with M. javanica only, L. bethae only, and the two species combined was reduced by 48%, 24% and 50%, respectively. CONCLUSION Meloidogyne javanica improves the performance of L. bethae, and combination of the two species has an additive negative effect on L. camara. The interaction between M. javanica and L. bethae could enhance the biological control of L. camara. © 2019 Society of Chemical Industry
