“…Previous studies have indicated that nutrient elements in plants are affected by a dilution effect caused by increases in plant size and biomass [16,38,39]; moreover, the element concentrations in leaves decrease with plant ontogenetic development [3,4,8,40]. In our study, the dilution effect affected P concentrations more than it did C and N concentrations.…”

“…However, in consideration of the un-repeatability in this study (due to age factors), the variations in leaf C, N and P concentrations among all of the larch stands might be due to age but could be due to differences in soil nutrients or other factors. Yang et al (2011b) indicated that increasing N and P concentrations in the soil increased leaf N and P concentrations [4]. Although soil nutrients were highly related to plant tissue nutrients, this finding does not suggest that a stable relationship existed between the soil nutritional status and nutrient concentrations or stoichiometric ratios in plants.…”

“…Such variations may be related to the migration of nutrient elements caused by changes in the balance between the uptake and utilization efficiency of these elements and differences in C fixation ability and N and P-use efficiency among the different growing seasons. These phenomena may lead to differences in the C, N and P concentrations of plant leaves [3,4,29].…”

“…Carbon (C), nitrogen (N) and phosphorus (P) are essential for plant growth and are vital in nutrient cycling, forest succession and the sustainable management of forest ecosystems. Carbon forms the structural basis of plants and constitutes one-half of the dry mass of plants [2][3][4][5]. Soil nutrient classification based on the national standard classification for soil nutrient content in 1982.…”

Abstract:The concentrations and stoichiometry of certain elements (carbon, nitrogen and phosphorus) are critical to the maintenance of plant functional and environmental adaptation during plant growth. We explore how the concentrations of C, N and P and the ratios of C:N, C:P, and N:P in the leaves of differently aged Larix principis-rupprechtii Mayr. plantations changed with growing season and stand age from 2012 to 2015 in the Qinling Mountains, China. The results showed that the element concentration and stoichiometric ratios in leaves were significantly affected by sampling month, stand age and sampling year; and multiple correlations with stand age were observed in different growing seasons. Compared to global element concentrations and stoichiometry in plants, the leaves of larch stands in the study region had higher C and P concentrations and C:N and C:P ratios but lower N concentrations and N:P ratios than global levels. The leaf N:P ratios of all of the larch stands were generally less than 14, suggesting that the growth of larch stands was limited by N in the study region. Our study facilitates the management and restoration of forest plantation and provides a valuable contribution to the global pool of leaf nutrition and stoichiometry data.

“…Warming may have a minor direct effect on soils, however e[CO 2 ] is unlikely to affect soil systems directly (Pritchard, 2011). It is more likely e[CO 2 ] will influence soil microcosms indirectly; through increased root exudates which function to increase available nutrients (Ma et al, 2005, Pritchard, 2011, Yang et al, 2007. These increased root exudates are likely to influence the micro-flora and thereby affect soil-borne pathogen populations.…”

Rising atmospheric CO 2 may impact on host and pathogen interactions to the benefit or detriment of crop productivity. The wheat disease Fusarium crown rot (FCR), caused by the pathogen Fusarium pseudograminearum, is predicted to increase in incidence with rising CO 2 due to changes in wheat resistance. Fusarium spp.regularly reduce the quantity and quality of wheat yields around the globe. Reported here are a collection of studies which show FCR incidence and susceptibility in wheat plants is likely to increase in a future with higher atmospheric [CO 2 FCR resistance, susceptibility and crown rot induced crop losses through lower grain weight, were dependent on host genotype. On average genotype L2-120, 2-49, and Sunco showed the highest resistance to FCR while Tamaroi, Janz and Wyalkatchem showed the lowest resistance. Overall, increasing atmospheric [CO 2 ] is likely to lead to a greater build-up of FCR inoculum in wheat, encouraging an increased disease incidence in susceptible varieties of wheat. With greater FCR incidence and subsequent changes to toxin production is likely to boost DON in plant stems. From this research it is likely that e[CO 2 ] will lower crop productivity where FCR is present and negatively impact on the quantity and quality of future crop yields. The consequences of these changes may be mitigated through crop breeding programs with the purpose of developing wheat varieties with improved FCR resistance, FCR tolerance and the ability to detoxify DON mycotoxin.iv

Management of phosphorus nutrient amid climate change for sustainable agriculture

Nutrients are essential for plant growth and development and influence overall agricultural production. Phosphorus (P) is a major nutrient required for many physiological and biochemical functions of a plant. Phosphate rock is the major source of phosphate fertilizer but is becoming increasingly limited in both developing and developed countries. The resources of phosphate rock need to be conserved, and import dependency on phosphate fertilizer needs to be minimized; this will help increase the availability of phosphate fertilizer over the next 300 yr. Climate change creates new challenges in the management of nutrients including P, affecting the overall production of crops. The availability, acquisition, and translocation of P are influenced by the fluctuation of temperatures, pH, drought, and elevated CO 2 . Both lower and higher soil temperatures reduce uptake and translocation of P. High soil pH affects P concentration and decreases the rate of plant P uptake. Low soil pH decreases the activity of soil microorganisms, the rate of transpiration, and P uptake and utilization. Elevated CO 2 decreases P uptake from soil by the plants. Future research is needed on chemical, molecular, microbiological, and physiological aspects to improve the understanding on how temperature, pH, drought, and elevated CO 2 affect the availability, acquisition, and transport of P by plants. Better P management strategies are required to secure the P supply to ensure long-term protection of soil fertility and to avoid environmental impacts such as eutrophication and water pollution, ensuring sustainable food production. INTRODUCTIONNormal growth and yield of plants depend on the optimum supply of nutrients. Each macronutrient and micronutrient plays a unique and irreplaceable role on the growth, development, and yield of crops. Its absence or deficiency invariably affects shape, size, weight, and other qualities of plants.
