“…Wardle et al [ 41 ] found that arthropod taxa increase with addition of organic matter as well as in organic farming systems. A significant effect of soil carbon on soil fauna has also been found in previous studies [ 42 – 44 ]. Furthermore, the carbon content of the roots greatly affected the species formation of Oribatida mites probably via rhizodeposition, as it feeds on dead roots or root-associated fungi [ 45 ].…”

Background: In Egypt, calcareous soils represent a large part of desert soils suffering from a shortage of nutrients and organic matter, affecting production and biological diversity in agroecosystems. Organic wastes, negatively affect the environment, recycling it as a promising technology in different farming systems, and its impact on crop productivity and soil fauna is largely unknown. In this study, the effects of integrating poultry manure (PM) alone or combined with vinasse (V) at rates of 4.2 g kg− 1 and 6.3 g kg− 1 in pots, on improving soil fauna diversity, soil fertility, soil consistency and yield of barley (Hordeum aestivum L.) grown in a calcareous soil were investigated. Results: The results showed that the addition of PM alone or combined with V at different rates led to a significant increase in the microbial biomass carbon (MBC), organic matter (OM), NPK soil availability and yield of barley. The addition of 6.3 g PM and 4.2 g V kg− 1 soil have the best results in OM with 65.0% compared to control, and V contributes more than 16% of them. Prostigmata and Collembola were the dominant groups and accounted for 43.3% and 50.0% in the PM1 and 50.0% and 20.0% in the PM2 of the total individuals, respectively. Shannon and Evenness indices increased significantly with the soil amended by PM alone or combined with V. Soil fauna plays a key role in soil consistency because of a significant relationship between soil fauna and soil OM, MBC and soil fertility index. The addition of 6.3 g PM and 4.2 g V kg− 1 soil gave the best results in grain yield by 76.90% compared to the control. Conclusion: In conclusion, the interaction between PM and V can be used as a promising organic amendments to increase barley yield and improve efficiency of a recycled PM and V on soil fauna and soil fertility of calcareous soil.

“…Islam et al 31 found a significant positive correlation between the soil Collembola population and organic amendments. A positive correlation between soil C and the total number of soil fauna has also been reported 31 – 33 . This result coincides with that obtained by Rosildaet al 34 who noticed that, the total numbers of Acari and Collembola species in soils increased with increasing soil OM content.…”

Enrichment of calcareous soils with phosphogypsum and poultry manure amendments could increase nutrient availability, improve calcareous chemical characteristics, and enhance barley plant growth. In the current study, phosphogypsum (PG) and poultry manure (PM) were used to determine the effects of PG and PM application on soil fauna diversity, soil fertility, and barley yield. The pot experiment treatments were: C: control; PG1: 4.20 g kg−1 soil; PG2: 6.30 g kg−1 soil; PM1: 4.20 g kg−1 soil; PM: 6.30 g kg−1 soil, and their combinations. The results indicated that the application of PM alone or combined with PG had significant effects on the microbial biomass carbon (MBC), organic matter (OM), soil NPK availability, and yield of barley. Collembola and Prostigmata accounted for 50.0 and 43.3%, respectively, of the total number of soil fauna. Shannon and evenness indices increased significantly in the soil amended with PM alone or combined with PG. Amended soil with PG and/or PM significantly increased the yield and yield components of plants compared to the control. The PM1PG2 treatment increased the yield by 76.2% above the control.

“…Crop biomass was highest and soil water content was below the estimated wilting point of approximately 14% at the latest sampling date. At this sampling date, soil water content reached an average of 10.3% of dry weight accompanied by the highest nematode, but lowest soil macro- (Myriapoda) and micro-arthropod (Collembola) abundance (see also 46 ). Given the limitations of complex field experiments, it is not possible to conclude on the major mechanistic links between variables that could cause the observed relationships.…”

Soil biodiversity constitutes the biological pillars of ecosystem services provided by soils worldwide. Soil life is threatened by intense agricultural management and shifts in climatic conditions as two important global change drivers which are not often jointly studied under field conditions. We addressed the effects of experimental short-term drought over the wheat growing season on soil organisms and ecosystem functions under organic and conventional farming in a Swiss long term trial. Our results suggest that activity and community metrics are suitable indicators for drought stress while microbial communities primarily responded to agricultural practices. Importantly, we found a significant loss of multiple pairwise positive and negative relationships between soil biota and process-related variables in response to conventional farming, but not in response to experimental drought. These results suggest a considerable weakening of the contribution of soil biota to ecosystem functions under long-term conventional agriculture. Independent of the farming system, experimental and seasonal (ambient) drought conditions directly affected soil biota and activity. A higher soil water content during early and intermediate stages of the growing season and a high number of significant relationships between soil biota to ecosystem functions suggest that organic farming provides a buffer against drought effects.
