This factsheet provides information about the history of soil testing calibrations and justification for recommending extraction of soil nutrients using Mehlich-3 for calcareous soils in Miami-Dade County. The dominant soils from this County have an extraordinarily high concentration of calcium res...

In this study, GIS and geostatistics technology were applied to analyze the spatial variability of soil organic matter, total nitrogen, available phosphorous and available potassium in paddy field in Pinghu County. Meanwhile, the spatial patterns of four soil properties were generated by ordinary kr...

Chilli anthracnose disease causes a huge commercial loss in the globe. Studying soil physico-chemical properties is crucial to understand chilli anthracnose because these properties significantly affect the efficacy of biocontrol agents and herbicides used to manage the disease. This study aimed to...

Plastic film mulch in agricultural production becomes essential to maintaining crop yields in arid and semiarid areas. However, the presence of residual film in farmland soil has also drawn much attention. In this study, three experiments were conducted. The first two experimental designs included 0...

Tree stems represent a long-lived biomass compartment for atmospheric carbon sequestration. While terrestrial biosphere models predict rising carbon sequestration in forests, direct observations of tree growth are inconclusive due to varying standardization procedures of tree-ring series and complex...

Parent materials and the fertility levels of paddy soils are highly variable in subtropical China. Bacterial diversity and community composition play pivotal roles in soil ecosystem processes and functions. However, the effects of parent material and fertility on bacterial diversity and community co...

The rational application of fertilization methods and the timing of film removal are crucial for enhancing tobacco yield and quality, as well as for promoting soil health. In our study, we established fertilization methods (hole fertilization and band fertilization) and film removal timing treatment...

Seasons often alter climate conditions and affect nutrient cycling by altering plant physiology and microbial dynamics. Plant growth and health depend on a symbiotic relationship with root microbes, however, the root-associated microbiota is key to plant evolution and ecosystem function. Seasonal ch...

Albic soil, which is generally oligotrophic, is a typical low-yield soil widely distributed in China. It is still unclear how to effectively improve soil fertility and strengthen the sustainable development of agricultural cultivation. For this purpose, 8-year field experiments were performed to det...
