“…Root K absorption were significantly dependent on the 20 ~ 40 cm soil, and significantly and positively correlated with pH value. The observed increase in pH could be associated with increasing soil cation exchange capacity [ 31 ], and K element was adsorbed from the soil solution to soil particles and root surface, thus reducing leaching loss and increasing root K absorption [ 32 ]. C. oleifera root Mg, Fe, Cu and Ca absorption was significantly dependent on the total amount of these elements in soil layer, increased with the depth of the soil, and were significantly positively affected by SMC except for Cu, which consistent with those reported by Cao et al [ 2 ].…”

Background Most of Camellia oleifera forests have low fruit yield and poor oil quality that are largely associated with soil fertility. Soil physical and chemical properties interact with each other affecting soil fertility and C. oleifera growing under different soil conditions produced different yield and oil composition. Three main soil types were studied, and redundancy, correlation, and double-screening stepwise regression analysis were used for exploring the relationships between C. oleifera nutrients uptake and soil physical and chemical properties, shedding light on the transport law of nutrient elements from root, leaves, and kernel, and affecting the regulation of fruit yield and oil composition. Results In the present study, available soil elements content of C. oleifera forest were mainly regulated by water content, pH value, and total N, P and Fe contents. Seven elements (N, P, K, Mg, Cu, Mn and C) were key for kernel’s growth and development, with N, P, K, Cu and Mn contents determining 74.0% the yield traits. The transport characteristics of these nutrients from root, leaves to the kernel had synergistic and antagonistic effects. Increasing oil production and unsaturated fatty acid content can be accomplished in two ways: one through increasing N, P, Mg, and Zn contents of leaves by applying corresponding N, P, Mg, Zn foliar fertilizers, while the other through maintaining proper soil moisture content by applying Zn fertilizer in the surface layer and Mg and Ca fertilizer in deep gully. Conclusion Soil type controlled nutrient absorption by soil pH, water content and total N, P and Fe content. There were synergistic and antagonistic effects on the inter-organ transport of nutrient elements, ultimately affecting N, P, K, Cu and Mn contents in kernel, which determined the yield and oil composition of C. oleifera.

Results In the present study, available soil elements content of C. oleifera forest were mainly regulated by water content, pH value total N, P and Fe contents. Seven elements (N, P, K, Mg, Cu, Mn and C) were key for kernel’s growth and development, with N, P, K, Cu and Mn contents determining the yield traits. The transport characteristics of these nutrients from root, leaves to the kernel were synergistic and antagonistic effects. There were two ways to control the oil production and the content of various oil components: one was to adjust N, P, K, Mg, Zn, Fe and Cu contents of leaves by applying corresponding foliar fertilizers, while the other was to change the soil water content and pH, and apply N, P, Zn, Mg and Ca fertilizers. Conclusion Soil type controlled nutrient absorption by soil pH, water content and total N, P and Fe content. There were synergistic and antagonistic effects on the inter-organ transport of nutrient elements, ultimately affecting the contents of N, P, K, Cu and Mn in kernel, which determined the yield and oil composition of C. oleifera.

“…The heightened availability of phosphorus exerts significant impacts on the growth and development of plants, as phosphorus is an indispensable element necessary for numerous physiological processes in plants, such as energy transfer and DNA synthesis. By facilitating the uptake of phosphorus, AMF empower plants to divert more energy towards growth and reproduction [34]. Furthermore, AMF also enhance the efficiency of nutrient utilization in plants by improving the absorption of other essential elements like nitrogen and potassium through the expansion of root surface area using their mycelium network.…”

Arbuscular mycorrhizal fungi (AMF) such as Rhizophagus intraradices (formerly known as Glomus intraradices) are of great importance to maintaining the soil ecosystem while supporting sustainable agriculture and practices. This review explores the taxonomy of Rhizophagus intraradices, their attributes, mycorrhizal symbiosis, plant growth improvement, nutrient recycling in the soil, soil health and environmental rehabilitation, and challenges that impede the effective use of AMF in agriculture. AMF impacts soil structure by releasing organic compounds like glomalin, improving total organic carbon and water-holding capacity, and reducing water scarcity. AMF, in sustainable agriculture, not only improves crop productivity through nutrient uptake but also enhances soil fertility and plants’ resistance to so-called stress from abiotic factors as well. The integration of AMF with other beneficial microorganisms in organic farming will be powerful both to ensure long-term soil output and to protect food from bacteria. Nevertheless, chemical inputs and spatial biases of the researchers remain matters to be solved in connection with the broad feasibility of AMF use.
