“…Los rangos de carbono (Cuadros 1 y 2), cercanos a 30 g 100 g -1 , en las chinampas estudiadas son parecidos a mejoradores orgánicos como el compost o estiércoles, e implican rápida degradación, siempre que existan rangos de temperatura entre 10 y 30 ºC y humedad entre 40 y 70% (Zanella et al, 2018a).…”

The chinampas are protected natural areas that have suffered degradation due to saline contamination and type of management. The objective was to study enzymatic activity and type of humus in chinampas with different salinity, land use and geographical location. Forty-five soil samples were studied, 15 at each site (Xochimilco, San Gregorio Atlapulco (SGA) and Tláhuac). Each site had a different use: five had pastures, five had agricultural crops and five were abandoned. pH, EC, saline ions, enzymatic activity (glucosidase, phosphatase, urease, sulfatase, catalase and dehydrogenase) and carbon in humic substances were evaluated. EC, PSI and pH classified the cultivated soils of SGA and Xochimilco as saline, but in Tláhuac the soils of abandoned and pasture chinampas were sodic saline. Geographic location and land use changed enzyme activity (except for urease and glucosidase) and characteristics of the humus [percentages of carbon of humic acids (HA) (humic acids), fulvic acids (FA), and humins]. There were statistical differences (Tukey P < 0.05). The cultivated soils had more urease, phosphatase and sulfatase activity, while in the pasturelands dehydrogenase and catalase were more active. Higher carbon content in AH was found in pastureland and chinampas of Tlahuac, while in SGA and abandoned chinampas carbon content was higher in FA.

“…Qualitative soil profile descriptions and the analysis of C/N ratios and pH values both in topsoil and subsoil can be very useful when interpreting soil C and N data for understanding the general context of the environment soil microorganisms live in (Li et al, 2018). Particularly, the characteristics of the litter layer are a very informative addition to the soil profile description, as they reflect the equilibrium between litter production, litter microbial decomposition, and interaction with the mineral soil (Zanella et al, 2018). Among microbiological techniques, one of the easiest and reliable techniques for defining soil microbiological status is the determination of microbial metabolic diversity by the Biolog method, having a high discriminating power between microbial soil communities from different soil environments and from soils subjected to various agronomic treatments (Sofo et al, 2010a,b).…”

It was time to take stock. We modified the humipedon classification key published in 2018 to make it easier and more practical. This morpho-functional taxonomy of the topsoil (humipedon) was only available in English; we also translated it into French and Italian. A standardized morpho-functional classification of humipedons (roughly the top 30–40 cm of soil: organic and organomineral surface horizons) would allow for a better understanding of the functioning of the soil ecosystem. This paper provides the founding principles of the classification of humipedon into humus systems and forms. With the recognition of a few diagnostic horizons, all humus systems can be determined. The humus forms that make up these humus systems are revealed by measuring the thicknesses of the diagnostic horizons. In the final part of the article, several figures represent the screenshots of a mobile phone or tablet application that allows for a fast recall of the diagnostic elements of the classification in the field. The article attempts to promote a standardized classification of humipedons for a global and shared management of soil at planet level.
