“…In any case, significant differentiation of P uptake was reflected in the contrast between fertilizer treatments and the absolute control (no fertilizer at all). Disparate to the results of other researchers (Aulakh, et al 2003;Feiza, et al 2003;Moskal, et al 1999), in the present study there were not observed significant differences between P total uptake on phosphorus treated objects and those untreated. Accumulation of this nutrient in cereals is determined mainly by its movement from the stem to the ear, the process of which starts before plant flowering (Manske, et al 2001).…”

The aim of this study was the assessment of macronutrient (N, P, K, Ca, Mg) accumulation in wheat at the critical phases of yield shaping as well as at the full ripening stage when judged at optimal P and K fertilizer rates applied as well as at reduced levels of fertilization with these elements. Four-year-long investigation on winter wheat was carried out in 2007-2010 within an agricultural holding located in vicinity of Śrem city (western Poland). The experiment was conducted under field conditions and based on the randomized-block design with four replications for each treatment. The factors investigated were differentiated P and K rates applied at constant N and Mg levels. Macronutrient accumulation in wheat differed depending on the element studied, plant development stage as well as P and K fertilization levels. The highest differentiation in macronutrient accumulation was observed at wheat flowering stage. At the full ripening stage, there were observed attributable to mineral fertilization significant differences in accumulation of K and Mg. Regression analysis proved that wheat grain yield was determined to the biggest extent by accumulation of K at BBCH 31 stage and that of N at BBCH 92 stage.

“…Phosphorus fertilization did not increase the plant dry matter but only increased the P content in the shoot (Table 5), probably due to the low P requirement of the peanut [20], confirmed by field studies [21,22]. Another explanation for this lack of response to P fertilization is a possible Mg deficiency in the peanut (Table 5), which may have been induced by K application.…”

Application of sewage sludge with high lead (Pb) contents may pollute soils and contaminate crops. The objective of this work was to evaluate peanut responses to application of sewage sludge with varying Pb contents in order to supply phosphorus (P) to the plant. A greenhouse experiment was carried out with peanut grown on soil sample from a medium-textured Haplustox. Treatments were arranged in 3 × 2 + 2 factorial scheme, replicated three times, distributed in randomized block design, and consisted of: three Pb rates applied to soil with sewage sludge (3, 21, and 42 mg kg −1 ) × two times of sewage sludge application (30 days before peanut sowing and at the day of the sowing) + mineral fertilization + control (without sewage sludge and mineral fertilization). Sewage sludge was efficient to supply P to peanut. Sewage sludge containing high rates of Pb, when applied, did not harm biomass and yield of the plant, but increased HCl-extractable Pb in soil and Pb content in shoot, roots, and pod husks. Increase of Pb content in pod husks may represent contamination risk of kernels and their products with fragments from husks detached during manipulation or industrial processing of peanuts.

“…Even though the P rates applied were relatively low, the increases were consistent with other studies which showed increases in plant available P with long-term P fertilizer application (Steffens 1994;Richards et al 1995). Aulakh et al (2003) found that 25 years of P fertilization on a semi-arid sandy loam soil increased Olsen-P by 63 to 436% compared to the initial 11.6 kg ha -1 with annual P application rates from 9 to 40 kg P ha -1 . The applied P was partially removed by crops (21 to 51%) with the remainder accumulating in the plough layer (33 to 64%) and/or leached to the lower soil layers (Aulakh et al 2003).…”

The fate and availability of P derived from granular fertilisers in an alkaline Calcarosol soil were examined in a 65-year field trial in a semi-arid environment (annual rainfall 325 mm). Sequential P fractionation was conducted in the soils collected from the trial plots receiving 0-12 kg P ha −1 crop −1 , and the rhizosphere soil after growing wheat (Triticum aestivum L. cv. Yitpi) and chickpea (Cicer arietinum L. cv. Genesis 836) for one or two 60-day cycles in the glasshouse. Increasing long-term P application rate over 65 years significantly increased all inorganic P (Pi) fractions except HCl-Pi. By contrast, P application did not affect or tended to decrease organic P (Po) fractions. Increasing P application also increased Olsen-P and resin-P but decreased the P buffer capacity and sorption maxima. Residual P, Pi and Po fractions accounted for an average of 32, 16 and 52% of total P, respectively. All soil P fractions including residual P in the rhizosphere soil declined following 60-day growth of either wheat or chickpea. The decreases were greater in soils with a history of high P application than low P. An exception was water-extractable Po, which increased following plant growth. Changes in various P fractions in the rhizosphere followed the same pattern for both plant species. Biomass production and P uptake of the plants grown in the glasshouse correlated positively with the residual P and inorganic fractions (except HCl-Pi) but negatively with Po in the H 2 O-, NaOHand H 2 SO 4 -fractions of the original soils. The results suggest that the long-term application of fertiliser P to the calcareous sandy soil built up residual P and nonlabile Pi fractions, but these P fractions are potentially available to crops.
