“…Nevertheless, as the P-PAE and Prhizon were even lower than the control, the use of this product for agricultural crop production is discouraged, especially on P-rich soils, so as to avoid further soil P accumulation. On the other hand, the product's ability to fixate P is of increasing interest for forestry on drained peat-and wetlands to reduce P leaching and increase P adsorption (Larsen et al, 1959;Nieminen et al, 2003Nieminen et al, , 2011Scheffer and Kuntze, 1999;Silfverberg and Hartman, 1999). A long study period will, however, be required because of the slow development of active root/mycorrhiza associations that may be necessary for significant P release (Nieminen et al, 2003(Nieminen et al, , 2011.…”

Phosphorus Use Efficiency of Bio-Based Fertilizers: Bioavailability and Fractionation

Although to date some technologies producing bio-based phosphorus (P) fertilizers have been proposed and implemented, the efficient use of the recovered products is still limited due to legislative constraints, lack of insights in their P release with time, and in the corresponding mechanisms. The aim of this paper was to evaluate the fertilizer performance in terms of P release and use efficiency of recovered struvite, iron phosphate (FePO4) sludge, digestate, and animal manure as compared to fossil reserve-based mineral triple superphosphate (TSP). First, product physicochemical characteristics and P fractionations in the context of European fertilizer legislation were assessed. Next, a controlled greenhouse experiment was set up to evaluate plant reactions as well as changes in P availability on sandy soils with both high and low P status. P soil fractions were determined in extracts with water (Pw), ammonium lactate (PAl), CaCl2 (P-PAE), and in soil solution sampled with Rhizon soil moisture samplers (Prhizon). Based on all results, long-term field trials evaluating the P release effect of struvite and digestate as compared to animal manure and TSP on different soil types with varying P status appear to be worthwhile. These products show promise as sustainable substitutes for conventional P fertilizers and could contribute to a more efficient use of P in agriculture. A refined classification of P application standards/recommendations in terms of soil P status, texture, and fertilizer characteristics, next to the crop P demand, is recommended. Moreover, the additional use of Rhizon samplers for determination of direct available P, including dissolved organic P, is proposed for better understanding and categorization of different P fertilizers in environmental and fertilizer legislations.

“…Steenari et al 1998, Larsson and Westling 1998, Perkiömäki and Fritze 2003. In general, peaty soils have low contents of P-sorbing Al and Fe hydroxides and oxides (Cuttle 1983, Nieminen andJarva 1996) and a number of studies have shown that the application of Al or Fe together with P increases adsorption and reduces leaching from organic soils (Larsen et al 1959, Fox and Kamprath 1971, Scheffer and Kuntze 1989. However, the P adsorption capacity of the native Al and Fe present in the soil before ash application may also increase after ash fertilization because of the liming effect.…”

Fertilization of drained peatland forests with wood ash and different commercial phosphorus fertilizers (calcium phosphates) generally give similar stand growth responses. However, it has been shown that use of calcium phosphate fertilizers generally lead to highly increased P release to recipient water courses. On the other hand, no corresponding release has been reported after ash fertilization. Soil samples from the surface peats from a nutrient poor and a fertile drained peatland site were collected before and 1-4 years after application of five different types of ash products. The changes over time in the different chemical forms of P in the substrate were studied. The results indicated that the reason for the low liability to leaching of ash fertilizers was that significant amounts of P are adsorbed by Al and Fe during weathering of the ash fertilizers. However, further studies are needed to clarify whether the adsorption of P occurs with the Al and Fe of the ash or the native Al and Fe compounds present in soil before ash fertilization.

“…The application of Fe or Al together with P has been shown to be an effective means of increasing adsorption and reducing leaching from peat soils (Larsen et al 1959, Fox and Kamprath 1971, Scheffer and Kuntze 1989, Nieminen 2002. It is not known, however, whether the phosphate fertilizers sorped by Al and Fe remain available to trees.…”

Soil samples from 15 eutrophic, 26 herb-rich, 15 tall-sedge, and 11 low-sedge drained peatland sites were analysed for easily soluble and aluminum, iron, and calcium bound phosphorus (P) using the Chang and Jackson sequential fractionation method. Compared to earlier investigations, where only total and easily soluble P contents (e.g. NH 4 OAc or dilute H 2 SO 4 extractable P) in peat have been analysed, significantly higher differences between sites were observed. The eutrophic sites were characterized by four to six-fold greater Ca-bound organic P and two to three-fold greater Ca-bound inorganic P contents than on the other three site type groups, whereas the average Al-bound inorganic P content of the eutrophic sites was only one-third of that at the other site types. Substantial differences between sites were also observed for Fe-bound inorganic P, i.e. two to four-fold greater Fe-P contents were measured at the herb-rich sites compared with the other three site type groups. The stand volume growth in the 67 studied drained peatland sites correlated significantly with Al-bound organic P and Fe-bound inorganic and organic P. The study showed that a detailed fractionation and discrimination of different forms of soil P is important in increasing the understanding of the relationship between P availability and vegetation community types and stand growth on drained peatlands.
