“…4E,F), and since pig manure is a liquid fertilizer, application of this product might cause a higher risk of leaching in the field, especially on soils low in Fe and Al (cfr. Kang et al, 2011;Yang et al, 2012). Since also the efficiency in terms of P uptake and yield on sand was slightly higher (Table IV) and the soil pH significantly higher for the digestate treatment than for pig manure (Fig.…”

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.

“…Some laboratory incubation studies have shown that the addition of manure could considerably increase the soil organic P fraction content (Reddy et al, 2000). Soil P fraction transformation has been a major focus of research in soil chemistry (Yang et al, 2012). The relationship between organic and inorganic P forms has been broadly discussed in several studies.…”

This paper examines phosphorus forms following application of organic fertilizer. Dynamic changes in the phosphorus fraction content were simulated by the waterlogged incubation method. This study was carried out using comparison tests between sterilized and non-sterilized treatments to analyze the effect of organic fertilizer on phosphorus form transformation. The experimental results showed that fertilization of paddy soil could significantly increase the content of the phosphorus fraction (p<0.05). Furthermore, the organic phosphorus content increased during incubation. The levels of organic phosphorus in the non-sterilized treatments were higher than in the sterilized treatments. However, the variation of the inorganic phosphorus content was contradictory. A significant correlation (r=-0.484, p≤0.01) was observed between O-P and highly resistant organic phosphorus, as well as among Al-P, Ca-P, moderately labile organic phosphorus and moderately resistant organic phosphorus. Therefore, it is concluded that applying organic fertilizer can increase the content of the phosphorus fractions of paddy soil. With microorganisms present, Al-P and Ca-P can be transformed into moderately labile organic phosphorus and moderately resistant organic phosphorus, and O-P can be transformed into highly resistant organic phosphorus.

“…It has been well documented that the bioavailability of P in soils is largely dependent on the relative abundance of various P fractions, which is affected by soil properties such as pH, parent materials, and physical particle distributions (Hedley et al, 1982;Levy and Schlesinger, 1999;Yang et al, 2012). Because of their high acidity and great fixation capacities, the bioavailability of P in red soils is relatively low in comparison with other soil types, such as calcareous and neutral soils.…”

“…The bioavailability of P in soils is defined as the sum of immediately available P (Ava-P), which can be converted from unavailable sources by naturally occurring processes (Yang et al, 2012). Most soil P must be solubilized (inorganic P) or mineralized (Org-P) into solution before it can be used by plants (Schachtman et al, 1998;White and Hammond, 2008).…”

“…It has been well documented that the main form of Org-P is phytate-P, which must be hydrolyzed to release soluble P before becoming available for plant growth. Among inorganic P fractions, Ca-P may mainly exist as the plant-inaccessible Ca10-P or Ca8-P, which gradually releases soluble P (Wang at al., 2010a;Yang et al, 2012). Alternatively, although inorganic P in Fe-P and Al-P is usually stable, insoluble, and unavailable for most plants, these forms are susceptible to dissolution and subsequently become available for some plant species, depending on soil texture, clay composition, and soil acidification (Li et al, 2008).…”

Red soil, the main soil type in south China, has many limitations for crop production, especially low phosphorus (P) bioavailability. Currently, little is understood concerning P fractions and their bioavailability for crops. In the present study, P fractions were analyzed from 50 red soil samples collected from regions leading agricultural production in Guangdong Province of south China. The most abundant P forms were iron-bound P (Fe-P) and organic P (Org-P), which, combined, account for 64.4% ± 1.9% of total soil P. Both Org-P and Fe-P had less bioavailability for soybean in sand culture than the other sparingly soluble P forms tested, with growth reduced by 78.0% ± 4.2% or 35.4% ± 6.7% and P content reduced by 50.2% ± 8.4% or 68.7% ± 1.8% when P was supplied as Org-P or Fe-P, respectively, compared with plants supplied with KH 2 PO 4 . Further field experiment using five crop species showed that P bioavailability in red soils is very low, as reflected by an average of 53.9% ± 2.9% loss in shoot P content for all tested crops in soils without P fertilization compared with plots amended with P fertilizer. After evaluation of root-toshoot ratio and specific root length, along with rhizosphere P depletion and acidification, it is reasonable to speculate that different crop species have evolved various strategies to overcome P deficiency in red soils. Among the tested crops, rapeseed displayed more rhizosphere acidification and lower carbon cost for maintaining root growth and subsequently possessed a superior ability to use and activate P from red soils than the other four crops.
