“…Moreover, previous studies have shown that the primary driver of soil multifunctionality was microbial biomass/abundance rather than microbial diversity ( Garland et al, 2021 ; Wang et al, 2021 ; Frew et al, 2022 ). In line with the previous studies, planting hairy vetch significantly increased the soil AMF abundance ( Jiang et al, 2021 ; Figure 1A ). A higher AMF abundance could result in the degradation of organic matter to release mineral nutrients for plants ( Treseder and Cross, 2006 ; Figure 4 ).…”

Multiple agricultural practices are being applied to increase crop yield in order to overcome the food shortage. Green manure has emerged as an appropriate practice to improve soil fertility and crop yield. However, the potential functions of arbuscular mycorrhizal fungi (AMF) in the below-ground ecosystems following the application of green manure in Ultisols remain largely unexplored. In this study, qPCR and high-throughput sequencing were used to investigate the response of AMF abundance and communities in different treatment groups, i.e., control (without fertilization), mineral fertilization (NPK), mineral fertilization with returning peanut straw (NPKS), and with green manure (hairy vetch; NPKG). The NPKG treatment significantly increased soil fertility compared to other treatment groups. Compared with control, the NPK, NPKS, and NPKG treatments increased peanut yield by 12.3, 13.1, and 25.4%, respectively. NPKS and NPKG treatments significantly altered the AMF community composition decreased the AMF diversity and increased AMF abundance compared to the control. The AMF network of the NPKG treatment group showed the highest complexity and stability compared to other treatment groups. The structural equation modeling revealed that the application of hairy vetch improved soil nutrients and peanut yield by increasing the soil AMF abundance and network stability. Overall, the results suggested that the application of hairy vetch might trigger positive feedback between the peanut and AMF community, contributing to fertility and yield improvement in the dryland of Ultisol.

“…Usually, acidic soils with high levels of Fe and Al will fix P, keeping available P low, but a large part of the variation here is linked to a high gradient of soil phosphorus in a few fields treated with organic liquid fertilizer during the growth phase of the crop. A meta-analysis from 54 published studies conducted over the last 20 years reported that even nutrient enrichment of organic origin can reduce native AMF richness in soils relative to no fertilization (Jiang et al 2021 ). This reduction is mentioned to be influenced by a shift in the balance of native AMF species (Johnson et al 2015 ).…”

Spatial variability and environmental drivers of cassava—arbuscular mycorrhiza fungi (AMF) associations across Southern Nigeria

Cassava, forming starch-rich, tuberous roots, is an important staple crop in smallholder farming systems in sub-Saharan Africa. Its relatively good tolerance to drought and nutrient-poor soils may be partly attributed to the crop’s association with arbuscular mycorrhiza fungi (AMF). Yet insights into AMF-community composition and richness of cassava, and knowledge of its environmental drivers are still limited. Here, we sampled 60 cassava fields across three major cassava-growing agro-ecological zones in Nigeria and used a DNA meta-barcoding approach to quantify large-scale spatial variation and evaluate the effects of soil characteristics and common agricultural practices on AMF community composition, richness and Shannon diversity. We identified 515 AMF operational taxonomic units (OTUs), dominated by Glomus, with large variation across agro-ecological zones, and with soil pH explaining most of the variation in AMF community composition. High levels of soil available phosphorus reduced OTU richness without affecting Shannon diversity. Long fallow periods (> 5 years) reduced AMF richness compared with short fallows, whereas both zero tillage and tractor tillage reduced AMF diversity compared with hoe tillage. This study reveals that the symbiotic relationship between cassava and AMF is strongly influenced by soil characteristics and agricultural management and that it is possible to adjust cassava cultivation practices to modify AMF diversity and community structure.

“…In cases where greater C org is detected in F i treatments compared to zero input controls is often due to a reduced rate of SOM loss rather than net SOM accrual (Ladha et al, 2011;Ndung'u et al, 2021;Tiefenbacher et al, 2021). Use of organic amendments, either alone or paired with F i , accelerates SOM accrual, and provides other benefits including increases in microbial abundance/activity, including beneficials such as arbuscular mycorrhizae fungi (Figure 5; Jiang et al, 2021). While fertilizers often improve crop yields in smallholder systems, sole reliance on F i does not provide expected yield boosts (Jayne et al, 2018) or deliver substantive soil health benefits (Ndung'u et al, 2021;Young et al, 2021).…”
