“…The grain contained 5-15 times more P than straw, which is natural for cereals [51]. The wide range of grain P to straw P proportion in our experiments confirms that plants primarily provide P for seeds, and a large part of assimilates are transported from older leaves and stems to the generative parts before harvesting [52,53].…”

“…None of the presented experiments showed a significant effect of the applied fertiliser treatments on the P content in wheat grain and straw. In experiment II, P content in grain increased under +PP, mainly due to reduced competition from weeds [54], but also partly at the cost of straw [53]. Plant protection did not change the effect of fertiliser treatments.…”

Can Phosphorus from Recycled Fertilisers Replace Conventional Sources? An Agronomic Evaluation in Field-Scale Experiments on Temperate Luvisols

Facing phosphate rock scarcity, growing food requirements and pollution problems with phosphorus (P)-containing waste, re-using P as fertiliser is becoming a real need. Innovative fertilisers from sewage sludge ash, animal bones and blood, activated by phosphorus solubilising microorganisms (PSM), were tested in field experiments with winter or spring wheat and compared with commercial fertilisers (superphosphate, phosphorite). Three levels of P doses were established (17.6, 26.4 and 35.2 kg/ha). This paper discusses the fertilisers’ impact on total soil P content and on the P content and P accumulation in wheat grain and straw, weeds and post-harvest residues. Recycled fertilisers maintained soil P stocks and supplied plants with P in the same way as traditional fertilisers, and ensured a comparable P pool in the post-harvest residues to traditional fertilisers. They also did not favour weeds during competitive crop-weed interactions. The PSM included in waste-fertilisers did not exert an evident effect on the soil P content or on the P content and P accumulation in plant biomass. The findings show the potential of recycled fertilisers to act as a substitute to fertilisers from primary sources. Further field research is needed to settle the question of the reasonability of PSM inclusion into fertilisers.

Thus, cow productivity and improved reproductive performance are directly connected to phosphorus intake (Wang et al, ).…”

Minerals in animal feed occur in variable structures, most of which determine the uptake and usage in biological processes in the body. Effective chemical breakdown of minerals may ensure efficient utilization in metabolism. The aim this study was to evaluate the effects of mineral supplementation on reproduction in cows. A farm was selected for the experiment due to the fact that it previously experienced different reproductive conditions in the farm. The farm comprises cross‐breed cows with Bonsmara dominating in the farm. Twelve pregnant primiparous and multiparous cows of different ages, parity and weight, that had previously experienced reproductive conditions, were randomly selected for this study. The cows were then randomly sub‐divided into two groups (experimental and control group) of six. The experimental group was injected with MULTIMIN™ + Se + Cu at a dosage of 1 ml/45 kg BW and Calci 50 p.i. at a dosage of 100–150 ml/500 kg BW at an interval of 6 weeks (from June to October 2017). Blood samples were collected before every injection date. The t test was used to relate the mean weight gain and serum metabolite between the experimental and control groups. The body weight gain was significantly higher in the experimental group compared to the non‐supplemented group. Supplemented cows had significantly (p < .05) high levels of triglycerides and creatinine kinase. A case of retained placenta and dystocia among non‐supplemented cows were noted. Thus, mineral supplementation can be used to improve productivity and reproductive well‐being.

“…Grain yield of rice are associated with P concentrations in grains. Previous studies have reported differences in the rice grain yield -P uptake relationships over regions (environments), genotypes, irrigation, and nutrient (nitrogen and phosphorus) management strategies (Dobermann et al, 1996;Vandamme et al, 2016;Wang et al, 2017;Wei et al, 2017;Song et al, 2019;Guo et al, 2020). For example, Dobermann et al (1996) reported that uptake of 1.8-4.2 kg P was required to produce one ton of grain yield by using the data from long-term experiments at 11 sites in five countries of Asia.…”

It is possible to simultaneously reduce both food security and environmental impact by understanding the relation between rice (Oryza sativa L.) grain yield and phosphorus (P) uptake requirements. The goal of this study was to determine P uptake requirements and relationship of P accumulation with yield formation at different rice grain yield levels under saline-sodic stress. A database comprising measurements in 28 plots in four on-farm research station located in saline-sodic soil area during the period 2018–2019 in Jilin province of Northeast China was used for the analyses. The grain yields of rice averaged 9.0 Mg ha−1 and varied from 5.11 to 13.41 Mg ha−1. The P uptake at late growth stages (heading and maturity) of rice gradually increased with increasing grain yield levels. The P requirement for producing 1 Mg grain (Preq.) were 4.61, 4.60, and 4.21 kg Mg−1 for grain yields ranging from <7.0, 8.0–9.5, and >10.0 Mg ha−1, respectively. The decrease in Preq. values with increasing grain yield was mainly attributable to the increase in the harvest index from 0.25 to 0.33. A larger proportion of the P was accumulated from heading to maturity stage when grain yields were higher than 8.0 Mg ha−1. The P uptake in leaves, stems and panicles at the maturity stage gradually increased with increasing grain yield levels. The results give a contribution to rice production in saline-sodic soils, and greatly optimize P management especially in high-yielding rice systems, furtherly improving food security in the Jilin province of China.
