“…Phosphorus is an essential nutrient and may be insufficient in ultramafic soils, where it is immobilised by ferrous oxides, reducing its availability for plants. However, Gavalda et al (2005) found that, in an Alfisol, the P-extractable content was enhanced by sludge supply and this was observable in our study for the highest dosage where P was in excess. This is interesting because the current study concerns a soil containing much more iron oxide than the soil used in Gavalda et al (2005).…”

“…It also affects chemical properties, increasing soil organic matter and, subsequently, soil fertility through bacterial mineralisation processes (Petersen et al 2003). Such amendment has resulted in maize, wheat and sunflower yields approaching those reached with inorganic fertilisers (Gavalda et al 2005). In addition to agricultural application, the positive effects on plant growth have helped in restoration of degraded sites.…”

Abstract. Soils from New Caledonia typically present poor nutrient content and large quantities of heavy metals such as nickel, chromium and cobalt, resulting in slow plant development. We evaluated the impact of sewage sludge application (0-30 t dry weight (DW) ha -1 ) on the passive revegetation of a former pine plantation. The spontaneously regenerated plant cover was mainly represented by the dominant Pinus caribaea, a shrub (Sannantha leratii), and a grass (Costularia comosa). The density of pine seedlings was significantly higher in the moderately amended zone (1.2 and 0.2 pines m -2 for 0.5 and 30 t DW ha -1 respectively). The same tendency was observed for S. leratii, but for C. comosa, no net change was observed. With no amendment, after 5 years many species were present, although aboveground biomass (0.3 kg m -2 ) was low, whereas, with sludge amendment, aboveground biomass was high (5 kg m -2 ) but diversity low. Amendment increased pine tree heights from 0.15 to 3.92 m with increased amendment from 0 to 30 t DW ha -1 . The uptake of nitrogen (N) by pine trees was also improved with sludge supply, as was the uptake of phosphorus (P). Regarding S. leratii, N and P levels were highest at the sludge dosage of 2 t DW ha -1 . Carbon storage in P. caribaea biomass increased from 0.40 to 180 kg m -2 with increased amendment applied. Five years after spreading at the highest amendment levels, available soil P remained enhanced. For heavy metal uptake by pine trees, no significant effect of sewage sludge was observed. The optimal dosage to stimulate biodiversity was 0.5-2 t DW ha -1 but maximal biomass was reached at 8-30 t DW ha -1 .

“…Mainly formed by illuviation, the argic horizon is compact and has a low internal permeability. As a result, water stagnates in the upper horizon during the winter, while the soils are actually dry in summer [34]. The soil of the study has a pH of 6.7 and its organic carbon content is 1%.…”

“…This soil type contains quaternary alluvial deposits from the rivers of South-West France. A great textural differentiation in the profile shows that surface horizon clay has been depleted and clay has accumulated in a 0.6 m deep argic horizon [34].

Pastures represent the major cropping system where biosolids are recycled in Florida, yet limited information is available documenting the agronomic benefits of biosolids recycling programs. A 2-yr experiment evaluated bahiagrass (Paspalum notatum Flügge) responses to application of biosolids and inorganic fertilizer applied either alone or in combination with biochar. Our hypothesis was that biochar could alter soil N and P dynamics, thus, affecting crop nutrient use efficiency. Treatments were a factorial arrangement of four fertilizer sources (inorganic fertilizer, thermally dried Class AA biosolids, aerobically digested Class B biosolids, and anaerobically digested Class B biosolids; surface-applied at 160 kg plant available N ha −1 yr −1 ) with or without biochar (applied at 1% wt basis). Bahiagrass total annual herbage accumulation was similar for biosolids and inorganic fertilizer treatments in 2017; however, inorganic fertilizer and aerobically digested Class B biosolids increased total annual herbage accumulation by as much as ∼29% relative to other sources in 2018. Biosolids and inorganic fertilizer increased bahiagrass crude protein (CP) concentration by as much as ∼22 and ∼39% in 2017 and 2018, respectively, compared to unfertilized treatment. No treatment effects were observed on in vitro digestible organic matter (IVDOM) concentration in 2017; however, in 2018 biosolids resulted in greater IVDOM than inorganic fertilizer. Data suggested no benefit of biochar on bahiagrass responses.Bahiagrass tissue mineral concentrations in both biosolids and inorganic fertilizer treatments were generally within sufficient range for optimum plant growth. Biosolids can be a viable alternative for sustainable bahiagrass production while reducing the dependence on inorganic fertilizer.Bahiagrass is a warm-season perennial grass species used for grazing and hay production in the southeastern United Abbreviations: AOAC, Association of Official Agricultural Chemists; CP, crude protein; IVDOM, in vitro digestible organic matter; PAN, plant available nitrogen.
