Key Factor

Soil fauna activity in agricultural soil is a key factor to maintain soil fertility and to assure soil ecosystem services. It is now accepted that agricultural practices like tillage and pesticide use can harm soil organisms including earthworms and springtails. Other practices like the use of green manure or animal manure have been considered as being beneficial to these soil invertebrates. To deepen our knowledge on the effect of fertilizers (mineral and organic) on earthworms (Aporrectodea caliginosa and Lumbricus terrestris) and springtails  (Folsomia candida) 56 microcosm experiments were made with two soil types and two hydric regimes. The microcosms were amended with four fertilizers: ammonium nitrate, mustard as green manure, cow manure and slurry. The results emphasize that mustard use had beneficial effect on Folsomia candida abundance and Aporrectodea caliginosa biomass, while mineral fertilizer had negative effects for all species used in the experiment.

Edaphic fauna play a crucial role in soil processes such as organic matter incorporation and cycling, nutrient content, soil structure, and stability. Collembolans in particular, play a very significant role in nutrient cycling and soil structure. The structure and functioning of the soil fauna can in turn be affected by soil use, leading to changes in soil characteristics and its sustainability. Therefore, the responses of soil fauna to different soil management practices, can be used as ecological indicators. Three different soil uses were researched: agricultural fields (AG) with 50 years of continuous farming, pastures entering the agricultural cycle (CG), and naturalized grasslands (NG). For each soil use, three fields were selected. Each sampling consisted of three soil samples per replicate. Collembolans were extracted from the samples and identified to family level. Five families were found: Hypogastruridae, Onychiuridae, Isotomidae, Entomobryidae, and Katiannidae. Soils were also characterized by means of physical and chemical analyses. The index of degree of change of diversity, was calculated. The results show that the biological index of degree of change can detect soil use effects on the collembolan community. Somewhat surprisingly the index showed that the diversity of collembolans is higher in the high anthropic impact site AG, followed by CG and being lower in lower impact sites, NG. The results also show that collembolan families respond differently to soil use. The families Hypogastruridae, Onychiuridae, and Isotomidae presented differences between systems. Therefore collembolan community structure can be a useful tool to assess agricultural practices´ impacts on soil.

The Impact

Intensive agriculture practices have an important impact on soil biota, which can affect dramatically soil quality. In order to limit this impact, alternative agricultural practices are more and more applied. However, these practices are still in progress and thus, it is necessary to investigate their impact on soil activity. In this context, we studied the impact of agricultural practices (intensive and agroecological) in vegetable cropping systems in Guadeloupe. The first aim of this study was to identify practices developed in vegetable cropping systems and explain their level of eco-agriculture. We conducted a survey on the whole territory which gave us a better understanding of vegetable cropping systems in Guadeloupe. We selected a representative subset of 18 farms located on vertisols. The second aim of the study was to establish a typology of cropping practices in these vegetable cropping systems in vertisol. We performed a PCA and a HCA on the 18 farms. These methods allowed us to build a typology in which farms were distributed between two types. In type A, farmers are using intensive agricultural practices while in type B, farmers are using alternative agroecological farming practices. Then, we collected soil fauna, during the rainy season in type A and type B farms in order to demonstrate the relationship between cropping systems and the quality of soils proxied by biological indicators. We hypothesized that the use of synthetic fertilizers and herbicides in intensive agriculture affected soil fauna activity. The results showed no significant difference between soil fauna abundance in both types. However, the taxonomic richness and the abundance of litter transformers were higher in type B. Taxonomic richness and soil fauna functional diversity thus strongly depend on agricultural practices in vegetables cropping systems in Guadeloupe.

Studies comparing agricultural practices that maintain a better quality and a healthy soil fauna consider the no-tillage farming as the most effective practice when compared to other planting techniques. In order to evaluate the influence of the no-tillage and conventional tillage methods (with and without manipulation of the soil before planting, respectively) on ant communities, we monitored two areas with these two types of practice (conventional and no-tillage) over the period of four years. We collected ants once per month along 10 transects randomly distributed using three pitfall traps in each area. In addition, we collected the dead plant biomass present at each point sampled as a parameter for measuring the environmental complexity of the areas. In total, we captured 27,480 individuals belonging to 26 species in the no-tillage area and 24,570 individuals belonging to 24 species in the conventional tillage area. The generalised linear model analysis showed that the no-tillage system had the highest abundance of individuals, as well as richness and diversity of species, during most of the study period, as compared to conventional tillage areas. We also found a significant positive correlation between species richness and dead plant biomass. Thus, it is possible to infer that the no-tillage area is a more complex environment with a greater diversity of ants and, therefore, a more sustainable agrosystem as compared to conventional tillage areas.

Soil management systems can alter the soil fauna compound by organisms of high sensibility to the agricultural practices, especially those practices that interfere with the soil structure. Thus, this study's objective was to evaluate the diversity of soil macrofauna at different soil depths and management systems. A 4×3 factorial scheme [four soil managements: 1- no-tillage system (NTS) implemented 6 years ago (NTS6), 2- NTS for 17 years (NTS17), 3- conventional planting system (tillage) for 20 years (CTS) and 4- native forest for 20 years (NF20); three soil depths: 0-0.1; 0.1-0.2 and 0.2-0.3 m] was set in a completely randomized design with five replications in an area of the Cerrado biome. The monolith method was used to sample the macrofauna from the litter and soil, where the number of individuals, total richness (TR), Shannon (SI) and Pielou (PI) indexes were quantified. TR values at a depth of 0-0.3 m were higher in the NTS6 and NTS17. The highest densities of individuals and TR occurred in the litter of NTS6. In the NTS17, at 0-0.1 m, the highest TR, SI and PI were recorded among the management systems. The TR, SI, PI values and the analysis of vertical distribution by Cluster, demonstrated that NTS areas are similar to the NF20 at all soil depths evaluated. The NTS areas presented the highest macrofauna indexes compared the CTS.

This is only an informal remark about some difficulties I am worrying about.I have tried to recalibrate the MK system in terms of intrinsic colour (B–V)0and absolute magnitudeMv. The procedures used have been described in a review article by Voigt (Mitt. Astr. Ges.1963, p. 25–35), and the results for stars of the luminosity classes Ia-O,I and II have been given also in Blaauw's article on the calibration of luminosity criteria in vol. III (Basic Astronomical Data, p. 401) ofStars and Stellar Systems.
