In western Burkina Faso, in the Bondoukuy cotton zone, on silty-clay soils, the rarefaction of the perennial grass Andropogon gayanus, characteristic of old fallows, is noticed. This grass is known to restore the structural stability of the soil rather quickly, due to a stimulation of biological activity, while the storage of organic matter in the soil remains slow. The biological aspect has been prospected through the study of invertebrate populations in 3 sites, all of which present 4 situations: 30-year-old fallows, 5-year-old natural fallows, and 5-year-old A. gayanus improved fallows and 10-year-old permanent crop fields. The results show that invertebrate populations are very diverse. A total of 172 morphotypes were recorded, including 115 species of insects (24 species of social insects), 31 species of Chelicerata, 8 Myriapoda and 5 earthworms. In the fields, earthworms and Diplopoda populations are less important than in old fallows. On the other hand, the fields have the highest species diversity, 50 species on average. The most abundant population is found in natural fallows, with a density of 835 individuals/m² and 43 species represented. Improved fallows with A. gayanus have a lower stand density and species richness than natural fallows (less than 50% and 43 species). In old fallows, stands are stable with a richness limited to 30 species, while earthworms and myriapods have significantly reduced densities. Soil invertebrate communities thus recover rapidly after crop abandonment and are fully active during the most intense phase of recovery in the first 5 years. Trees do not appear to have a significant effect on the conservation and stimulation of macrofauna except for Coleoptera. Our results show that the cropping system adopted in the region allows for minimal conservation of soil macrofauna and that the macrofauna recovers rapidly during the fallow. Improved fallows with A. gayanus differ from natural fallows in limiting Termite density, while old fallows and fields are of comparable density.

“…The samples were subjected to chemical analysis in a lab. Percentage of soil moisture was determined by collecting samples from 15 cm soil depth and measuring the dry and wet weight of the sample [2], Percentage of matter and organic carbon was measured using Walky-black method, Electrical conductivity was measured using soil saturated extract [8], Nitrogen was measured using Kjeldahl's measurement technique, Phosphorus was calculated using the technique proposed by Olsen Ribeiro et al [26], potentiometric acidity was measured using a pH meter [12], soil texture was calculated using Bukas hydrometry method, and bulk density was measured using the agglomeration method). In order separate macrofauna, a soil sample collected by the sampling frame was dumped on the surface of a nylon, then the macrofauna was carefully separated, and placed in 70% alcohol for identification.…”

“…In addition, soil is recognized as a globally important reservoir of biodiversity because macrofauna is an important component of soil biodiversity [7][8][9][10]. Macrofauna can be used as a biological indicator of the impacts on land use, for its relationship with the physical and chemical properties of the soil, and for its rapid variation over a short period of time that is a product of changes in cover and transformation in vegetation [3,[11][12][13].…”

“…In another study, Tsufac et al [21] found that t increasing tree species diversity and density leads to increasing soil macro-fauna diversity and density in cocoa-based agroforestry systems [22,23]. Sembiring et al [12] investigated soil macrofauna diversity after eight years of Mount Sinabong eruption in Sumatra, Indonesia. The results of this study showed that the thicker the volcanic ash covering the soil surface, it would reduce soil moisture, soil water content, organic C, and soil pH, but on the other hand, increase the soil temperature [24,11].…”

The present study was an attempt to compare the correlation between physicochemical properties of soil and diversity and density of soil macrofauna in Juniper and amygdalus stands of Geno protected area during the growing and resting seasons. To this end, researchers field visited part of the forest at an altitude of 2200 m asl. and identified a half-hectare Juniper and a half-hectare Amygdalus stand. 10 points were randomly selected to place the sampling frame and measure the macrofauna and soil physicochemical properties. Soil samples were collected at 15 cm soil depth using a rectangular sampling frame (15 × 10. 10 cm) in growing and dormant seasons. Shannon-Wiener and Simpson diversity indices were used to evaluate the biodiversity of the identified macrofauna, and then Menhinick's and Margalef

Toba highlands is unique and covers a large area. Peat plays an important role as a carbon sink, and is currently utilized for agricultural purposes, use as firewood, and left to degrade. The use of peatlands will impact the maturity of peat, and the emission of carbon dioxides and other gases caused by the decomposition process of microbes. A brief transformation of organic carbon from peat into carbon dioxide negatively impacts the environment, especially in increasing the greenhouse gas emissions. C-organic and C-microbial biomass was observed in peatlands of the Toba Highlands in Humbang Hasundutan, employing the Walkey and Black method, and fumigation and extraction methods to calculate the microbial population involved in the decomposition process or called C-microbial biomass. Moreover, descriptive method were used to map their distribution in the peat areas. The results showed that the highest C-organic was found in barren land at 22.05% and soil C-microbial biomass population was 3.24 µg g−1 soil, whereas the least C-Organic was found in peatland transferred to coffee fields, at 5.23% while the least C-microbial biomass was in peatland transferred to onion fields at 0.28 µg g−1 soil. There was a relatively small amount of organic matter and C-microbial biomass in paddy field, shallots, and grasses. Therefore, the results indicated that converting peatland into agricultural land would likely change the value of organic matter and C-biomass population.
