“…In total 50 permanent plots (24 m 2 each plot) which were monitored since 2014 have been considered in this study. We have used the same treatments in each studied year (for more details about the studied treatments see , Melo et al 2019, Forstall-Sosa et al 2020, Nascimento et al 2021. Sampling was carried out in each studied year from July to December, and this study shows the results obtained until 2019.…”

“…Sampling was carried out in each studied year from July to December, and this study shows the results obtained until 2019. The climatic conditions of the study area are classi ed as tropical with drysummer characteristics (As-type climate following Köppen-Geiger climate classi cation), average annual precipitation, and mean air temperature of 1.300 mm and +22.5 °C, respectively (Nascimento et al 2021). The soil type of the studied site was classi ed as a Regosol with sandy loam texture (WRB 2006).…”

“…The soil parameters evaluated were soil pH, soil exchangeable cations (K + , Na + , Ca 2+ , Mg 2+ , Al 3+ ), sum of bases, cation exchange capacity (CEC), soil organic carbon, base saturation, soil bulk density, soil microporosity, total porosity, soil macroporosity, soil eld capacity, permanent wilting point, available water content, soil aeration capacity, and soil available water capacity. Details of methods used to measure each treatment can be found in Nascimento et al (2021).…”

“…In this study, we have used data from a green manure farming system because this experiment is monitored for changes in soil physical, chemical, and biological properties using permanent plots established in tropical environment since 2014. Previous works have shown that cover crops used as green manure are key for improving soil organic carbon, shoot dry biomass production, and soil biota diversity and abundance Melo et al 2019;Forstall-Sosa et al 2020;Nascimento et al 2021). Leguminous plant species seem to promote a positive plant-soil feedback as described by Souza and Santos (2019).…”

“…From an economic point of view, the use of green manure practice provides important bene ts to smallholder farmers by reducing costs with fertilizers and other soil conditioners (Zhou et al 2020). In fact, this practice reduces in 69% the overall costs with only organic fertilizers in certain regions such as the Brazilian Northeast (Nascimento et al 2021).…”

Soil quality index shed light on soil health and its capacity to sustain high primary production. It also can assist decision-making in farming systems by integrating this valuable product into soil management planning. However, the currently existing models are based on rather local data, and thus, there is a lack of predictive tools to monitor soil quality on farming systems at tropical conditions. We characterized soil physico-chemical properties, plant biomass production under a 6-year experiment in a sandy soil from Tropical ecosystem, using ten treatments: Brachiaria decumbens, Canavalia ensiformis, Crotalaria juncea, Crotalaria ochroleuca, Crotalaria spectabilis, Lablab purpureus, Mucuna pruriens, Neonotonia wightii, Pennisetum glaucum, and Stilozobium aterrimum. We found that most of the soil physico-chemical properties were correlated with each other by Pearson’s correlation analysis. On the other hand, RDA illustrated that shoot dry biomass was related to soil C stock, K+, macro- and microporosity. Soil pH, Al3+, Ca2+, Mg2+, K+, Olsen’s P, Na+, soil C stock, bulk density, microporosity, macroporosity, and permanent wilting point were the main factors driving primary production in our long-term study. Our findings suggest that: 1) a consecutive green manure practice without any input of fertilizers after 6 years changed positively by increasing soil fertility (e.g., Ca2+, Mg2+, K+ and Olsen’s P), and improving plant growth and soil quality in tropical savanna climate conditions; and 2) the 33 multivariate predictive models may provide a deeper view about the benefits of using plant species as green manure by creating positive plant-soil feedback thus promoting soil quality.

This study analyzed arbuscular mycorrhizal fungi (AMF) activity and soil chemical properties in Aspidosperma pyrifolium, Bauhinia ungulata, Caesalpinia pyramidalis, and Caesalpinia ferrea. AMF spores, root colonization, total glomalin‐related soil protein (T‐GRSP), easily extracted GRSP (EE‐GRSP), and soil chemical properties were measured four times (July 2019, 2020 and December 2019, 2020). Significant differences were observed in AMF spores, root colonization, T‐GRSP, and EE‐GRSP among the plant species and across seasons. For soil chemical properties, we observed differences among plant species. During the dry season, B. ungulata and C. pyramidalis had the highest AMF spores and root colonization (57.3 ± 0.27 spores 50 g soil−1 and 48.8 ± 1.05, respectively), whereas during the rainy season, C. pyramidalis and C. ferrea showed the highest AMF spores and root colonization (36.6 ± 0.13 spores 50 g soil−1 and 62.2 ± 1.17, respectively). A. pyrifolium showed the highest T‐GRSP in both seasons. On the basis of the soil chemical properties, we found that (i) A. pyrifolium, B. ungulata, and C. ferrea showed the highest soil organic carbon (1.32 ± 0.03 g kg−1), phosphorus (7.01 ± 0.26 mg kg−1), and soil pH (5.85 ± 0.23) and (ii) C. pyramidalis showed the highest Ca2+, Mg2+, Na+, H+ + Al3+, K+, and soil total nitrogen (1.36 ± 0.04, 0.73 ± 0.01, 3.72 ± 0.85, 4.56 ± 0.12 cmolc kg−1, 15.43 ± 1.53 mg kg−1, and 0.16 ± 0.01 g kg−1, respectively). Our results highlight the advantage of AMF spores as perennating structures over other AM fungal propagules in seasonal vegetation like Caatinga.
