Changes in soil phosphorus fractions following positive and negative phosphorus balances for long periods.Plant Soil.254:245-261. BLAKE L, JOHNSTON AE, POULTON PR, GOULDING KWT. 2003. Changes in soil phosphorus fractions following positive and negative phosphorus balances for long periods. Plant ...
The phosphorus positive ions (cations) produced by chemical ionization reactions were observed by sampling the flame through a nozzle into a mass spectrometer. This study follows on from Part I in which the phosphorus negative ions (anions) were similarly investigated. About a dozen phosphorus ...
phosphorus-efficient genotypes to improve the phosphorus use efficiency of crops while mitigating the negative environmental impacts. This approach can conserve non-renewable phosphorus resources and improve the nutritional quality of food. Therefore, understanding the core genes of crops under varying phosph...
It should be pointed out that the Ids increased as Vg changed from negative to positive, when we used Al (Φ ∼ 4.0–4.3 eV) as contact electrodes in the z-PNB devices. It indicates that the electrons, rather than holes, were the major carriers in the z-PNB devices. Thus, ...
(TOF-SIMS). TOF-SIMS facilitates the sputtering of the solid residues and detects the ions in both positive and negative ion detection modes (Fig.2). Since the sputtering might also fragment the phosphorus oxoacids, these fragmentation patterns have to be determined. This assists in an ...
9). Total N and P component had a positive correlation with most DAMs in Fig. 9. EC had a positive correlation with compound_3740 (Quebrachitol) and compound_1656(Choline), and a negative correlation with pH. Compound_0206 ((5E,8Z)-4,7-dihydroxy-2-methyl-2,3,4,7-tetrahydrooxecin-...
Structural equation modeling demonstrated that changes in plantinputs predominantly drove the positive impacts of P fertilization rate and experimental duration, as well as thenegative impacts of background P contents on soil respiration and microbial biomass C responses to P fertilization.Our study ...
For example, soil pH has a significant negative impact on PRE of secretohalophyte and pseudohalophyte, EC has a significant positive impact on PRE of glycophyte. However, euhalophyte was not significantly related to these factors. The foliar of euhalophyte have developed water storage tissues and...
while the content of the soluble salt in the regolith also increased. We predicted that the positive impact brought in by the pre-culture period, maybe extra nutrients, or other microbial derived plant hormones, counteracted the negative impact that soluble salt content has on plant growth. We ...
(APAavg);n = 3 samples. The blue and red squares represent positive and negative correlations, respectively. The numbers represent the Spearman correlation index. The * and ** indicate 5% (p < 0.05) and 1% (p < 0.01) significant level, respectively (Nonparametric Spearman ...
