“…In agreement with previous report (Banaj et al, 2006;Kovačević et al, 2008), maize grain yield and shoot biomass were significantly increased with P application. It was reported that the critical soil available P concentration to reach the yield plateau was varied in different areas due to the maize cultivars, soil type, pH and soil organic matter content (Bai et al, 2013).…”

“…In the intensive cultivation of high-yielding crop cultivars, at least 30-50% of the crop yield is attributable to the application of commercial fertilizers (Stewart et al, 2005). Although phosphorus (P) fertilizer can substantially increase maize grain yield (Banaj et al, 2006), excessive P fertilizer typically does not result in additional yield increases (Bai et al, 2013) but can lead to environmental pollution (Guo et al, 2010;Le et al, 2010) and deficiencies in Zn, copper (Cu), and Fe of maize (Cakmak, 2002;Stein, 2010). In China, for example, approximately 40% of the soils are Zn and Fe deficient, and about 30% are manganese (Mn) and Cu deficient (Liu, 1991).…”

Decreased micronutrient concentration in cereal grains caused by excessive application of phosphorus (P) fertilizer may contribute to reduce their nutritional quality. To help correct this problem in maize grain, a 3-year field experiment was conducted to determine how P application rate affects micronutrient partitioning in maize shoots and other plant organs and micronutrient bioavailability in grain. Phosphorus application significantly decreased shoot zinc (Zn) and copper (Cu) concentrations at all growth stages but had no effects on shoot iron (Fe) and manganese (Mn) concentrations. As the P application rate increased, shoot Zn and Cu contents decreased, and shoot Fe and Mn contents increased. The ratios of pre-anthesis to post-anthesis mineral contents were not affected by P application rate except Zn. P application increased the percentage of Zn that was allocated to grain and decreased the percentage that was allocated to other tissues, but had no effects on the allocation of other micronutrients among tissues. The bioavailability of Zn, Cu, Fe, and Mn in grain decreased as P application rate increased. Overall, taking account of grain yield and nutrients concentration, P fertilizer rates should range from 12.5 to 25.0 kg P ha −1 under the local condition. It can be concluded that not only grain yields, but also nutritional quality, should be considered in assessing optimal P rates in maize.

“…Zinc concentrations in maize were decreased due to application of P, while S, Fe and Mn status in plants were mainly independent on applied fertilization. Banaj et al (2006) applied three rates of P fertilization up to 2000 kg P 2 O 5 ha -1 on hydromorphic soil of Sava valley area. Leaf P, Mg, Mn and Fe concentrations increased by application of the highest rate of P. At the same time, K, Ca, Zn, Cu and Fe concentrations significantly decreased.…”

“…The application of phosphorus (P) fertilizer in intensive agriculture production is a crucial measure for increasing grain yield [9,10], but it may affect the micronutrient contents in grain. The antagonistic effects between P-Zn and P-Cu have long been observed before now [11,12].…”

Phosphorus Application Decreased Copper Concentration but Not Iron in Maize Grain

Copper (Cu) and iron (Fe) are essential micronutrients for plants and animals. How phosphorus (P) application affects Cu and Fe concentrations in maize grain still remains unclear. Two-year field studies were conducted in a long-term experiment with six P levels (0, 12.5, 25, 50, 100, and 200 kg∙ha−1 P) on calcareous soil. Phosphorus application significantly decreased the average grain Cu concentration by 12.6% compared to no P treatment, but had no effect on grain Fe concentration. The copper content increased as the P application rate increased from 0 to 25 or 50 kg·ha−1, but then decreased, while Fe content kept increasing. As the P application rate increased, the specific Cu uptake by the roots decreased, but not for Fe. The root length density in response to P application had a positive relationship with shoot Cu and Fe content. The shoot Cu content and grain Cu concentration decreased with the reduction in the arbuscular mycorrhizal fungi (AMF) colonization of roots due to increasing P application. The reduction in grain Cu concentration with increasing P rates could be partly explained by the decreasing uptake efficiency.
