“…Previous studies have evaluated the influence of P fertilizer application on cereal grain Zn concentrations, usually with specific conditions and single experiments (Friesen et al 1980;Debnath et al 2015;Drissi et al 2015;Dang et al 2016;Coetzee et al 2017;Iqbal et al 2017;Sánchez-Rodríguez et al 2017). The conclusions regarding the P-Zn relationship have sometimes been quite different.…”

Zinc (Zn) deficiency is a well-documented worldwide problem for crops and humans. Although phosphorus (P) fertilizer application achieves high grain yield in intensive agricultural systems, it can reduce Zn availability in cereal grains. Therefore, a quantitative evaluation of the P-Zn antagonism is needed. A global meta-analysis of 51 publications with wheat, maize, and rice was performed to quantitatively analyze the effect of P application on grain Zn concentration. Phosphorus application reduced grain Zn concentration by 16.6% for wheat, 20.2% for maize, and 0% for rice. Phosphorus application did not affect soil available Zn concentration but, averaged across the three crops, significantly decreased root Zn concentration by 9.94%; the reduction was associated with a reduction in colonization of roots by arbuscular mycorrhizal fungi. Phosphorus application did not affect shootto-root or grain-to-straw ratios of Zn concentration, indicating that Zn translocation and remobilization within the plant were not reduced by P application. Especially for wheat and maize, the P-Zn antagonism was explained by a "dilution effect" and the suppression of Zn uptake efficiency by roots rather than by a suppression of translocation and remobilization. In addition to partially explaining the cause of the P-Zn antagonism, this is the first study using meta-analysis method to quantitatively demonstrate a P-Zn antagonism for Zn concentration in wheat and maize. Biofortification for increasing the grain Zn concentration may benefit from an increased understanding of how P application affects rhizosphere and root processes.

“…At the same time, APP can gradually hydrolyse into orthophosphate in the soil, which is more conducive to absorption by maize roots, thereby reducing the probability of P precipitation, and increasing yield. APP not only contains the nitrogen and P required by crops, but also increases the effectiveness of micronutrients in calcareous soils, which is beneficial for crop yield (Coetzee et al., 2017).…”

Phosphorus (P) is the main limiting nutrient in agriculture. Most of the P fertilizers applied to the soil remain ineffective because of the weak movement and transfer of P in the soil. Current agricultural production requires large amounts of P fertilizers, leading to the accumulation of residual P in the soil and serious ecological problems. Fixation of P is a vital reason for limited fertilizer effectiveness. Therefore, improving soil P effectiveness is the key to reducing soil P accumulation. This study explored the effects of different water‐soluble P fertilizers on maize yield and economic benefits by comparing the relationships between soil P distribution and P absorption and utilisation of maize in a calcareous soil of Xinjiang province in China. The main results indicated that (1) the drip application of ammonium polyphosphate (APP) and urea phosphate (UR) was more beneficial for increasing the total P content in the deep soil layer; the drip application of APP was beneficial in increasing the available P content of the deep soil layer. (2) Dripping acid fertilizer was more conducive to reducing soil acidity and alkalinity (pH). (3) The application of different P fertilizers favoured the accumulation of P in all organs of maize, among which APP and UP were the most effective since they increased accumulation by 75.8% and 60.4% (at flowering stage) and 98.2% and 62.3% (at maturity stage), respectively, compared with CK (without P fertilizer). (4) pH was the main factor affecting P uptake and transformation, and the drip application of P fertilizer had the most significant effect on pH. (5) The application of different water‐soluble P fertilizers increased maize yield and economic benefits. Among the five water‐soluble P fertilizers selected in this study, APP had the greatest economic benefits, followed by UP and Monoammonium phosphate (MAP); they increased yields by 31.6%, 24.5%, and 22.0%, respectively, compared with CK.

Nitrogen (N) and phosphorus (P) nutrient enrichment is important for grasslands. This study aimed to determine how soils enriched with N and P influenced soil concentration correlations and affected the growth kinetics, mineral nutrition, and nitrogen-use efficiencies of Vachellia sieberiana grown in a greenhouse experiment. The soils used as the growth substrate were analysed and showed extreme acidity (low soil pH, 3.9). Nitrogen-enriched soils were more acidic than P-enriched soils. Exchangeable acidity was strongly negatively correlated with an increase in soil pH, with soil pH between 3.9 and 4.1 units showing the strongest decline. Plant saplings showed increased root biomass, shoot biomass, total biomass, and plant N and P concentrations when grown in soils with high soil P concentrations. Extreme soil acidification in N-enriched soil was one of the main factors causing P unavailability, decreasing sapling growth. Extreme soil acidification increased concentrations of toxic heavy metals, such as Al which may be alleviated by adding lime to the extremely acidic soils. Research implications suggest that soil pH is an important chemical property of the soil and plays a significant role in legume plant growth. Legume species that are unable to tolerate acidic soils may acquire different strategies for growth and functioning.
