TL;DR: In this article, a review of 634 publications on biochar and biochar-compost mixtures as soil amendments is presented to identify the potential gaps in our understanding of the role of these amendments in agriculture.

TL;DR: An overview of possible mechanisms involved in DS tolerance through improved water and nutrient uptake using extraradical hyphal growth; effective spatial configuration of root system; elevated concentration of tetramine spermine; osmotic adjustment through non-structural carbohydrates; scavenging reactive oxygen species through antioxidant enzymes and antioxidants; and glomalin-bound soil structural improvements are suggested.

TL;DR: The results confirmed that mycorrhization brought significant changes in root FA compositions, in addition to regulation of gene expression responsible for increasing the unsaturation level of FAs, a pre-disposing physiological event for better drought tolerance of citrus.

TL;DR: Results indicated that AMF-stimulated greater root-hair growth of trifoliate orange under DS that is independent on AMF species is related with mycorrhiza-modulated auxin synthesis and transport, which benefits the host plant to enhance drought tolerance.

TL;DR: In this paper, the authors proposed an integrated soil management system representing different modules of INM for combating an untimely decline in citrus orchards' productivity, where soil condition-based rootstock alternatives, site specific nutrient management coupled with variable rate application, and integrated SOI management systems represent different modules.
