“…To accurately comprehend the quality of soils, there is a need to establish a quality index, which integrates different soil parameters along with their stratification and proper allotment [ 20 , 21 ]. A numerical soil quality index (SQI) that can provide a single value for each soil by combining the impact of all quantitative parameters will be considered and termed as indicators now onward [ 7 , 22 ]. This SQI can also evaluate and reflect the soil degradation due to land-use changes and management practices [ 21 ].…”

Indian soils are inherently poor in quality due to the warm climate and erosion. Conversion of land uses like forests to croplands and faulty management practices in croplands further cause soil degradation. This study aimed to understand the extent of these impacts in a small representative part of eastern India, covering Himalayan terai and nearing alluvial plains. Soils were collected from (i) forests, (ii) croplands (under agricultural practices for more than 50–60 years) and (iii) converted lands (converted from forests to croplands or tea gardens over the past 15–20 years). Different soil quality indicators were assessed and soil quality index (SQI) was generated to integrate, scale and allot a single value per soil. Results indicated that continuous organic matter deposition and no disturbances consequence the highest presence of soil carbon pools, greater aggregation and maximum microbial dynamics in forest soils whereas high application of straight fertilizers caused the highest available nitrogen and phosphorus in cropland soils. The SQI scorebook indicated the best soil quality under forests (x¯ 0.532), followed by soils of converted land (x¯ 0.432) and cropland (x¯ 0.301). Comparison of the SQI spatial distribution with land use and land cover confirmed the outcome. Possibly practices like excessive tillage, high cropping intensity, no legume in crop rotations, cultivation of heavy feeder crops caused degraded soil quality in croplands. This study presented an example of soil quality degradation in India due to land use change and faulty management practices. Such soil degradation on a larger scale may affect future food security.

“…Es así como en el estudio de las características que determinan la calidad y aptitud de los suelos de cementerio, para el establecimiento de parques urbanos, precisan la evaluación de la fertilidad y características microbiológicas, de las cuales los atributos más representativos del sistema son los contenidos de N, Fe, Ca, Mg, K, carbono orgánico, conductividad eléctrica y presencia de comunidades microbianas patogénicas, en la elaboración de indicadores de calidad del suelo, que permiten determinar la distribución espacial de estas cualidades y su heterogeneidad en el terreno, para el desarrollo de un marco de gestión y cualificación de los servicios ecosistémicos de los espacios verdes urbanos. También establecen que para condiciones ambientales templadas con suelos que tengan buena aireación y drenaje, temperaturas relativamente altas y un período de once años, el ecosistema de los suelos de cementerios abandonados, se aproxima al equilibrio comparable con otros suelos de la ciudad, que propicia el desarrollo sostenible de la vegetación y el manejo efectivo de los ecosistemas urbanos [25,34,35].…”

Este artículo muestra las aproximaciones interdisciplinarias que integran conocimientos respecto a los suelos de cementerios contemporáneos y antiguos e inhumaciones clandestinas que producen interés científico bio-geo-arqueológico, forense reciente, lo anterior es lo que compila el estudio de los Necrosoles. Las investigaciones al respecto, plantean interrogantes pedogenéticos, antropogénicos, morfológicos, de características físico-químicas y microbiológicas. Así los Necrosoles se definen con precisión e incluyen en propuestas para sistemas taxonómicos locales y mundiales. Los suelos de los cementerios tienen propiedades físico-químicas y microbiológicas variables, antrópicas, temporalidades e insumos orgánicos e inorgánicos exógenos y predominancia de procesos de cambio ambiental. Actualmente, las necrópolis en las urbes y la proximidad a fuentes de agua e impactos de estos suelos en la salud pública y ambiente, se evalúan en investigaciones científicas. También aumenta el interés por las características de entierros ilegales de cuerpos humanos e integración de herramientas pedológicas y forenses. Revisamos los estudios de Necrosoles y el desarrollo de la investigación científica experimental ligada a efectos e implicaciones de entierros humanos

“…Additionally, emerging studies have identified the need to understand forensic ecology for soil provenance [11] and ecosystem services of exhumed gravesites before they are repurposed for other societal needs such as recreational spaces in densely populated urban areas [12,13]. Therefore, this preliminary study was designed to test the capacity of microbial community dynamics to determine time-since-burial and subsequent emptying of a clandestine grave.…”

Advancements in molecular microbial ecology techniques have enabled researchers to study the complex interactions of epinecrobiome, necrobiome, and thanatomicrobiome communities during cadaver decomposition within novel forensic disciplines. This preliminary study tracks shifts in subsurface soil necrobiome as indicators of time-since-exhumation where whole juvenile Sus scrofa domesticus was used as the human cadaver proxy. Principal component analysis of DGGE-based diversity index (Shannon-Weiner, HꞋ; Simpson (D)) measurements showed more consistent delineation of pre- and post-exhumation periods of the fungal 18S gene with further clustering for days 270 and 300. More importantly, high-resolution metabarcoding of the 16S rRNA gene recorded temporal bacterial clock indicators at order and family levels. Specifically, Xanthomonadales (11.29%) and Xanthomonadaceae (4.27%), and Verrucomicrobiaceae (4.00%) were abundance-based season (spring–summer) and microbial clock indicators for post-burial interval (PBI) ≥ 150 days. Hydrogenophilales (7.13%) and Hydrogenophilaceae (7.56%), Clostridiales (4.57%) and Clostridiaceae_1 (3.13%), and Bacteroidales (3.33%) defined the impacts of 120 days since exhumation of Sus scrofa domesticus. They could, therefore, be tracked to identify grave emptying for the current soil type.
