Abstract  

The design of a rigorous experimental procedure is the basis for any environmental study. In this work, the basic criteria are established for determination of soil health using microcalorimetry as the main technique complemented by the study of physical (temperature, moisture, porosity, hydraulic conductivity, density and plasticity), chemical (pH and C to N ratio) and biological features (most probable number of microorganisms and organic matter content), and also environmental properties in the form of bioclimatic diagrams. The design was elaborated using as a reference a humic eutrophic-Cambisol subjected to afforestation with P. pinaster Aiton situated in Viveiro (Galicia, NW Spain). Main results of this study refer to total heat evolved during the processes (2.65 to 3.81 J g–1), time to reach the maximum of the peak from 16.17 to 19.29 h, and microbial growth rate constant from 0.0732 to 0.1043 h–1. These results change over the year as they are influenced by the action of environmental parameters over soil microbial activity. The results are in close agreement with some others previously reported using different experimental techniques.

Abstract  

This work is a ‘historical’ revision of the evolution of an experimental procedure developed by Prof. Lisardo Nez and his research group TERBIPROMAT to study the sustainability and the soil health state. From the very beginning, in 1993, the microbial activity was the main bioindicator selected to analyse the ‘soil health state’. For this reason, a microcalorimetric technique was used lately to analyse the influence of different human activities such as reforestations, agricultural exploitation or pollution on the microbial activity in different soils. Microcalorimetry is the main scientific technique used in this research to follow the stimulation of the microbial activity by addition of glucose. The data obtained were complemented by a study of physical, chemical and biological parameters of soil and allowed to follow the microbial activity in soils of Galicia (Spain) along the year. The final results, still in revision, will be helpful in establishing a data basis for real maps of the ‘health state’ of different soils. Such maps could be used to design processes that help us to decide how we should exploit soils ensuring their sustainability.

In the review traditional characteristics of the soil quality are discussed. Soil health (SH) along with its soil quality and fertility, is considered as the most important, functional characteristic of any soil ecosystem (SE). The consistent patterns and results of the study of structure and functions of the microbial community (MC) of the soil ecosystem were generalized to substantiate the quantitative parameters of soil health. The author’s developments for definitions of soil and soil health are given. The prospects of using the parameters of SH for diagnostics at recovery and biological rehabilitation of technogenically disturbed soils are proposed.

Summary Soil productivity and health were analyzed using an experimental procedure designed for this kind of studies. The continuous loss of fertile soil obliged the Food and Agriculture Organization (FAO) to declare soil as an item to be protected as a support of the world society welfare. The procedure here described is in accordance with the premises necessary for a rational and sustainable development of soil and the resources it contains and can be used to study any soil all over the world. The study was carried out using soil microbial population as a bioindicator of soil health. Microbial activity was followed using the microcalorimetric technique. The microcalorimetric study can be complemented through a deep analysis of soil physical, chemical and biological properties together with a study of the environmental properties that have a strong influence on the afore mentioned properties and, thus on the microbial activity in soil. The different properties follow different ASTM, ISS/FAO, USDA, etc. well defined standards. The experimental procedure reported in this work could be very helpful to create a data basis that could be useful to quantify and control soil potentiality or design soil decontamination and recovery systems.
