“…C. oleifera root absorption of Al and Zn elements were not affected by the total amount of these elements in the soil. When the SMC decrease, the observed pH increase may reduce Mn, Al and Zn elements exchange capacity in soil [ 36 ], leading to reduced leaching loss and correspondingly increased Mn, Al and Zn elements root uptake. In conclusion, Fujian soil of C. oleifera forest was mainly regulated by SMC, pH, and total soil elements content.…”

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.

“…These results indicate that root Mn, Al and Zn absorption had no relationship with these elements total amount in the soil, and that the absorption was determined by soil moisture content. When the soil moisture content decrease, the observed pH increase may reduce Mn, Al and Zn elements exchange capacity in soil [33], leading to reduced leaching loss and correspondingly increased Mn, Al and Zn elements root uptake. In conclusion, Fujian soil of C. oleifera forest was mainly regulated by soil moisture content, pH, and total soil elements content.…”

Background Most of C. oleifera forests have low yield and poor quality, largely associating with soil fertility. Soil physical and chemical properties interact with each other to affect soil fertility. C. oleifera growing under different soil conditions affected their yield and oil composition. Three main soil types were selected, and redundancy, correlation, and double-screening stepwise regression analysis were used, for exploring the relationships between Camellia oleifera nutrients uptake and soil physical and chemical properties, shedding light on the transport law of nutrient elements from root, leaves, and kernel, and elaborating 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 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.

“…Two soils with desired properties were selected based on our previously published work 20 , 29 , where an identical biochar (wood chips pyrolysed at 700 °C) was used. The relatively higher biochar production temperature (700 °C) was preferred due to the need for producing relatively stable biochar with relatively lower ammonium and a higher nitrate sorption capacity.…”

This study aimed on the increasing nitrogen use efficiency (NUE) of maize via the use of high temperature produced biochar (700 °C). Maize was grown to maturity on two contrasting soils (acidic Cambisol and neutral Chernozem) in pots with a treatment of biochar co-applied with ammonium sulphate stabilised by a nitrification inhibitor (3,4-dimethylpyrazole-phosphate, DMPP) or un-stabilised. The combination of biochar with ammonium sulphate containing DMPP increased maize biomass yield up to 14%, N uptake up to 34% and NUE up to 13.7% compared to the sole application of ammonium sulphate containing DMPP. However, the combination of biochar with un-stabilised ammonium sulphate (without DMPP) had a soil-specific influence and increased maize biomass only by 3.8%, N uptake by 27% and NUE by 11% only in acidic Cambisol. Further, the biochar was able to increase the uptake of phosphorus (P) and potassium (K) in both stabilised and un-stabilised treatments of ammonium sulphate. Generally, this study demonstrated a superior effect from the combined application of biochar with ammonium sulphate containing DMPP, which improved NUE, uptake of P, K and increased maize biomass yield. Such a combination may lead to higher efficiency of fertilisation practices and reduce the amount of N fertiliser to be applied.
