a Sampling points distribution coloured by vegetation cover type across biogeographical regions. The number of sites is indicated between brackets. b Vegetation cover types ordered along a gradient of increasing land-use perturbation. Full size image Here, we find that microbial diversity and potential...
Due to various factors, including the high cost involved in remediation interventions, it is essential that a holistic and tiered, risk‐based approach be adopted that is founded on international best practice, to address remediation in a uniform manner across the country. This is relevant irrespect...
An electrical potential is imposed across the electrodes and the resistance of the solution between the electrodes is measured. The measured conductance is a consequence of the solution's salt concentration and the electrode geometry whose effects are embodied in a cell constant. At constant potential...
Table 1 Depth variation in soil organic carbon (SOC) properties averaged across the three soil types Full size table We adopted a bioenergetic framework to assess how SOC dynamics could be related to its energy quality for microbial decomposers25,26,27,28, defined here as the net energy gain ...
Overall, averaged across many published scientific studies, biochar increases crop yields about 20% with application rates often exceeding 10 t ha−1. It has also been reported that applications of less than 5 t ha−1 can increase crop yields by over 50% in certain types of soils. Even ...
It is possible that the functional groups on the nanoparticle surface and their affinity to ionization remained consistent across the two soil solutions, leading to a similar shift in the IEP. (ii) Both acidic and slightly alkaline soil solutions can contain species that can protonate or de...
Land degradation is a serious threat to agriculture which is adversely affecting the soil functions and productivity, while degraded soils stretch up to 6 billion ha worldwide. The population of the world is increasing day by day and agricultural land is
Our meta-analyses for land-use transition effects on community metrics highlighted a consistent trend across the two studied taxa. This pattern relates declining land use intensity with positive effects on community parameters, especially in agricultural lands. This trend is consistent with a number of...
(iii) map the spatial–temporal distribution of soil legacy P across the country; and then (iv) forecast the future agricultural P balance and savings up to 2050, considering potential management strategies to explore more efficiently the use of modern phosphate fertilisers, and soil legacy P for...
Here, we studied 16 long-term chronosequences from six continents and found that the ecosystem type is more important than soil age (centuries to millennia) in explaining the proportion of unprotected and mineral-associated carbon fractions in surface soils across global biomes. Soil carbon pools ...
