“…Low availability of Zn (< 1.0 mg of AB‐DTPA extractable Zn kg −1 soil) and P (< 10 mg of Olsen‐P kg −1 soil) to plants occurs in calcareous soils because of their high fixation and low organic matter contents ( Okalebo et al, 2002; Maqsood et al, 2011; Ahmad et al, 2012; Imran et al, 2015; Table 1). Therefore, application of Zn and P improved plant growth and yield parameters ( Sattar et al, 2011; Hussain et al, 2012, 2013; Rehim et al, 2014), which is in agreement with the present study (Fig. 1).…”

Phosphorous (P) and zinc (Zn) are plant nutrients that interact with each other in soil–plant systems. Such interactions may cause deficiency of one of the nutrients interacting with each other if interactions are antagonistic. In the present trial, a field experiment was conducted to investigate the interactive effect of Zn (0 and 16 kg ha−1) and P (0 and 60 kg ha−1) on growth, yield and grain Zn concentration of two maize (Zea mays L.) genotypes, i.e., Neelam (local) and DK‐6142 (hybrid). Growth and yield of both maize genotypes were increased by the application of Zn and P treatments compared with control, but Zn+P was more effective than their sole application. When compared to control, combined application of Zn+P increased grain Zn and P concentrations by 52% and 32%, respectively, averaged for the two genotypes. Single application of P decreased grain Zn concentration by 10% over control. Application of P and Zn particularly in combination decreased the grain [phytate] : [Zn] ratio and increased the estimated human Zn bioavailability in grains based on a trivariate model of Zn absorption in both maize genotypes. Conclusively, combined Zn+P application appeared more suitable for enhancing grain yield and agronomic Zn biofortification in maize grains. However, Zn fertilization aiming at increasing grain yield and grain Zn concentration should consider the genotypic variations and P rate.

“…This was apparent since we found an effect of the P addition on the biomass production and no effect for the tissue P concentration. These positive effects support the first part of hypothesis (i) and are in agreement with previous findings for total P content [15,18,19] and biomass production [15,[19][20][21] in relation to P addition.…”

“…The tissue P concentrations indicated that plants grown in the material treatments were below the limit for optimal growth. According to former research, the tissue P concentration for optimal maize growth has been reported to 1.5-2.9 mg P g −1 DW [19,25,28,29]. Plants grown in the material treatments had concentrations well below this limit, with P concentrations ranging 0.64-0.76 mg P g −1 DW, while plants grown in the NPK treatment was in the reported internal P requirement range.…”

(1) Phosphorus (P) is an essential plant nutrient, and P deficiency negatively affects plant growth and development. Furthermore, P is a finite and nonrenewable resource, and there is an urgent need to recover P from some of the important waste streams in society. Newly engineered calcareous materials (sol–gel coated cat litter (CATSAN®)) can bind P from wastewater in decentralized treatment systems and potentially enable P recycling into agricultural production by direct addition of the P saturated material. (2) The effects of the addition of two P-enriched calcareous materials as fertilizers for maize (Zea mays L.) growth were investigated in a mesocosm experiment. We compared fertilization with the P-enriched materials at rates of 6, 12, 25, 50, 100 kg P ha−1 yr−1 with fertilization with commercial NPK fertilizer. (3) The P fertilization by the P-enriched materials had a significant positive effect on plant height, biomass, maximum light-saturated photosynthetic rate, respiration rate, and total P content in biomass. However, plants fertilized by the commercial NPK fertilizer performed significantly better in the majority of measured parameters at identical fertilization rates. (4) The bioavailability of the P bound to the calcareous material was very low. However, the studied material has the potential to be used as part of a decentralized treatment solution to remove and subsequently recover and recycle P from wastewater.

“…Internal P requirement of soybean and wheat was determined at flowering stage and the values were highest in inoculation with both biofertilizers and 0.5 P plots for both the crops. Inoculation of VAM, which helped in mobilizing P more efficiently from soil to crops, that enhanced the IPR in both the crops treated with 0.5 P + PSB + VAM as compared to plots treated with 1.0 P, although the latter plots had significantly higher rhizospheric available P (Rehman et al, 2005;Sarfraz et al, 2009;Sattar et al, 2011).…”
