“…Species richness was higher on abandoned kraals for both belowground and aboveground habitats, an indication that abandoned kraals are a favorable habitat in terms of feed quality and quantity that supports a variety of macro‐invertebrates (Wardle et al., ). Other studies have also recorded a high species richness of soil macro‐invertebrates on nutrient‐rich habitats (Ayuke et al., ; Doblas‐Miranda et al., ; Hemerik & Brussaard, ; Manyanga, Mafongoya, & Tauro, ). Unlike belowground macro‐invertebrates, species abundance for the aboveground habitats was similar at both sites, possibly indicating that aboveground macro‐invertebrates were less sensitive to soil nutrients and plant biomass than belowground macro‐invertebrates.…”

This can be accounted for by the generalist feeding behavior and habitat preference (relatively unresponsive to small changes in resource quality) by aboveground invertebrates (Laossi et al, 2008).…”

Abandoned cattle (Bos taurus) kraals are sources of habitat heterogeneity in dystrophic semi‐arid African savannas with a strong positive effect on soil nutrients and plant productivity. However, little is known regarding how macro‐invertebrate assemblages vary between abandoned kraals and the surrounding savanna matrix. We tested whether herbaceous biomass and basal and aerial covers and soil nutrients have an effect on aboveground and belowground macro‐invertebrate assemblages. Twelve abandoned kraals were contrasted with their paired control plots for soil characteristics, herbaceous productivity, and macro‐invertebrate assemblages in Save Valley Conservancy, Zimbabwe. Abandoned kraals had significantly higher concentrations of soil nitrogen (N), phosphorus (P), potassium (K), and calcium (Ca) as well as herbaceous biomass and basal and aerial covers than control plots. Both aboveground and belowground macro‐invertebrate species richness were higher on abandoned kraals. However, only belowground macro‐invertebrate diversity (Shannon H′ and Hill number 1) was significantly higher on abandoned kraals. Soil nutrients and herbaceous productivity had positive and significant correlations with the dominant taxa (Coleoptera, Hymenoptera, Hemiptera, Isoptera, and Myriapoda) on abandoned kraals. These results add to the growing body of evidence that abandoned kraals exert significant effects on savanna spatial heterogeneity years later, with implications on ecosystem processes and functioning.

“…Nutrient input is still necessary under fallow management (Gregory et al, 2016). Improved fallow systems in Africa have also involved the addition of organic amendments to improve soil fertility, and maize yields increased after the fallow period (Manyanga, Mafongoya & Tauro, 2014). According to some studies, plants belonging to Fabales can improve soil quality and fallow efficiency by promoting nitrogen fixation (Akobundu, Ekeleme & Chikoye, 1999; Sileshi & Mafongoya, 2006; Wick, Kühne & Vlek, 1998).…”

Fallow management can improve the soil nutrients in the topsoil and upper subsoil. However, little is known about the effects of short-term (one year) fallowing with different treatments, such as vegetation and fertilization, on subsoil (20–40 cm) properties. We conducted field trials to explore the changes in subsoil properties in response to such treatments in the Yellow River Delta region in China. Different vegetation and fertilization treatments were applied, and we measured the carbon and nitrogen contents, microbial biomass and microbial community structure in the subsoil. Fallowing without manure resulted in the storage of more total nitrogen (16.38%) than fallowing with manure, and meadow vegetation improved the ammonium nitrogen content (45.71%) relative to spontaneous vegetation. Spontaneous vegetation with manure improved the microbial biomass nitrogen (P < 0.05). Although the impact of short-term fallowing on microbial community structure was low, an effect of management was observed for some genera. Blastopirellula, Lysobacter, and Acidobacteria Gp6 showed significant differences among fallow treatments by the end of the year (P < 0.05). Blastopirellula abundance was related to the microbial biomass nitrogen and nitrogen mineralization rate in the subsoil. Manure retained a high abundance of Lysobacter, which may strengthen soil-borne disease resistance. The response of Acidobacteria Gp6 showed that meadow vegetation without manure may not benefit future crops. Although the treatments did not significantly improve microbial community structure in the one-year period, annual fallowing improved certain subsoil properties and increased the number of functional genera, which may enhance crop productivity in the future.

“…Soil physical attributes lead to improved quality of chemical and biological attributes of soil, especially soil biological attributes that are directly influenced by the fauna. Macrofauna diversity causes an increased mikrofauna cluster so that the cycling of nutrients process becomes faster (Manyanga et al, 2014). There is no significant correlation between available P and diversity macrofauna proofen in this study, because P available more influenced by microfauna (Setälä et al, 1990)…”

Indonesia is a country with the third largest biodiversity after Brazil and Madagascar. Of the about 325.530 species of flora and fauna globally, an estimated 25% of the world's species are found in Indonesia. Macrofauna, a land animal that plays a role in influencing the soil ecosystem has specific environmental requirements that enables it to be used as biological indicators of ecosystem conditions, mainly rice paddy ecosystem. This research is necessary owing to the demand for an easy and accurate indicator in predicting soil fertility for farmers. In addition, this study conducted in July TO August 2018 can be used as an inventory of macrofauna indigenous species that may still remain in the paddy field, Dukuhseti district. The implementation of observations was done in paddy fields in the Dukuhseti district in Pati regency, Central Java. Macro fauna specimens and soil samples were taken at various points. 121 individual macro faunas were found and divided into three phyla and 10 Order. The results showed that macro fauna diversity was not always positively correlated with soil chemical properties. Total N, available P, organic C and pH is not directly proportional to the increasingly diverse types of macro fauna in a rice field. The soil's chemical nature in the form of base saturation has a positive correlation with macro fauna diversity that makes it serve as an indicator of fertility. Base saturation in the fields can be associated with the presence of different kinds of macrofauna decomposers such as earthworms, millipedes and denitrivor. Indigenous macrofauna species was not found in the paddy fields in the Dukuhseti district due to intensive land management.
