“…Therefore, the macro- and micronutrient concentrations in plant biomass were different among different plant parts, species, and regions under N addition. These differences may be attributed to differences in plant species and soil properties ( Zhang and Shan, 2000 ; Fang et al, 2012 ; Simic, 2015 ).…”

“…Most studies indicated that N addition results in significant increases in the availabilities of micronutrients, such as the available concentrations of Cu, Mn, and Fe in soils ( Malhi et al, 1998 ; Tian et al, 2015 ; Tian et al, 2016 ; Wang et al, 2017 ), which significantly increased after N addition. However, Malhi et al (1998) indicated that the concentrations of Cu and Zn in soils significantly decreased under higher treatments of N. These discrepant results show that changes in macro- and micronutrient concentrations in plants and soils vary widely probably because of differences in the year of fertilization, plant species, and soil properties ( Zhang and Shan, 2000 ; Cheng et al, 2010 ; Fang et al, 2012 ; Simic, 2015 ; Tian et al, 2016 ). Moreover, only a few studies examined the allocation of macro- and micronutrient concentrations in plants and the influence of the main soil nutrients on the macro- and micronutrient concentrations in soils.…”

The effects of nitrogen (N) addition on the macro- and micronutrient concentrations, storage, and allocation of Bothriochloa ischaemum (L.) Keng, a native forage plant on the Loess Plateau in China remain unclear. We studied the effects of N addition at 0 (CK), 2.5 (N1), 5.0 (N2), and 10.0 (N3) g N m-2 y-1. N addition significantly decreased the available copper (Cu), zinc (Zn), and total Cu concentration, but significantly increased the available iron concentration in the soil. Cu, manganese (Mn), and sodium (Na) concentrations in aboveground tissues and potassium (K), magnesium, and Zn concentrations in belowground tissues significantly increased with N addition. Calcium (Ca) concentrations in belowground tissues decreased significantly. The ratios of above- to belowground Ca, Cu, Zn, and Mn significantly increased with N addition. The maximum ratios appeared at N2 for Cu, Zn, and Mn. The aboveground, belowground, and total biomass storage of studied nutrients significantly changed with N addition, and most attained maximum values under N2 treatment. The storage ratios of above- to belowground Cu, Zn, Mn, and Na attained maximum values at N2. We conclude that N addition significantly, but differentially influence the macro- and micronutrient concentrations and storage in B. ischaemum. B. ischaemum allocated and accumulated increased macro- and micronutrients to its aboveground tissues and exhibited high total storage when the amount of N addition reached 5 g N m-2 y-1.

“…Cook (1998), cited by McLaughlin et al (2000), indicated that correlations between DTPA extractable metal in soil and plant concentrations were generally low, except for Zn, although the correlations were generally best in soil with metal salt and sewage sludge amended. However, Zhang and Shan (2000) found that among different extractants, DTPA represented a highly available fraction of the total content. Brun et al (2001) showed a good correlation between the DTPA extractable fraction and the accumulation on root maize grown on Cu contaminated soils.…”
