Continuous cropping problems constitute threats to perennial plant health and survival. Soil conditioners have the potential to enhance plant disease resistance in continuous cropping systems. However, how microbes and metabolites of the rhizosphere respond to soil conditioner addition remains largely unknown, but this knowledge is paramount to providing innovative strategies to enhance plant adaptation in continuous cropping systems.

Layered double hydroxide intercalated with mercaptosuccinic acid (MSA-CFA) holds considerable promise for remediating cadmium (Cd)-contaminated soils through selective immobilization; however, its stability under acidic conditions has yet to be investigated. The acidic stability of MSA-CFA was investigated by acid stability investigation and simulated soil acidification. In the immersion test, the cadmium dissolution rate (DR) for the Cd immobilized products of MSA-CFA (MSA-CFA-Cd) was significantly lower (2.

Soil acidification poses a significant threat to agricultural productivity and ecological balance. While lime is a common remedy, it can have limitations, including nutrient deficiencies and potential soil compaction. Therefore, exploring alternative and sustainable amendments is crucial.

The topic of sustainable water management has become of paramount importance at a global level, especially when considering the high-amount of water used in agriculture, which is a threat to water resource balance. Focused on 38 inventories of nonirrigated vineyard management in the Franciacorta wine-growing region in Italy, this study aims to understand how agronomic practices impact water resources. The integrated statistical approach, based on generalized linear models, reveals how context variables influence different water footprint indicators, such as water scarcity, acidification and freshwater ecotoxicity.

This study examined the impact of long-term manure organic fertilizer application (3, 8, 13, 18, and 22 years) on soil physicochemical properties, heavy metal (HM) accumulation, and microbial communities. Long-term manure application markedly elevated nutrient levels such as available N, P and K, and organic matter content in surface and soil profile. Total and DTPA-HM content in different vertical profiles increased with the application time.
