“…Quantifying the relationship between total P and P accumulation in the soil can be used to build a model to predict the changes in soil total P with soil PAB [ 35 ]. The positive linear correlation of soil total P concentration and soil PAB has been reported in long-term upland field trials, which indicated that most of the P accumulated within the soil profile when the applied P was greater than the required plant P [ 36 ]. In this study, for every 100 kg P·ha −1 surplus, the total P in surface soil increased by only 44.4 mg kg −1 , which was lower than that reported in other studies (e.g., 67 mg·kg − 1 in paddy soil) [ 37 ].…”

Excess phosphorus (P) accumulation in the soil can change the bioavailability of P and increase the leaching risks, but the quantitative evaluation of these responses in acidic red soil is lacking. This study aimed to investigate the composition of soil P fractions under different phosphorus apparent balances (PAB) in acidic red soil and the bioavailability and the leaching change-points of different P fractions. Five phosphorus (P) fertilization rates were applied (0, 16.38, 32.75, 65.50, 131.00 kg P·ha−1) in every sweet corn cultivation from the field experiment, and the treatments were marked as P0, P1, P2, P3, and P4, respectively. The PAB showed negative values in P0 and P1 which were −49.0 and −15.0 kg P·ha–1 in two years, respectively. In contrast, PAB in P2 as well as in P3 and P4 were positive, the content ranging from 40.2 to 424.3 kg P·ha−1 in two years. Per 100 kg ha−1 P accumulate in the soil, the total P increased by 44.36 and 10.41 mg kg−1 in the surface (0–20 cm) and subsurface (20–40 cm) soil, respectively. The content of inorganic P fractions, including solution phosphate (Sol-P), aluminum phosphate (Al-P), iron phosphate (Fe-P), reduction phosphate (Red-P), and calcium phosphate (Ca-P), significantly increased by 0.25, 16.22, 22.08, 2.04, and 5.08 mg kg−1, respectively, in surface soil per 100 kg ha−1 P accumulated in the soil. Path analysis showed that the most important soil P fractions contributing to Olsen-P were Sol-P and Al-P, which can directly affect Olsen-P, and their coefficients were 0.24 and 0.73, respectively. Furthermore, the incubation experiments were conducted in the laboratory to investigate the leaching risk of different P fractions, and they showed Sol-P was a potential source of leaching, and the leaching change-points of Al-P and Fe-P were 74.70 and 78.34 mg·kg–1, respectively. Continuous P that accumulated in soil changed the composition of P fractions, and the bioavailability as well as the leaching risks increased. This is important in optimizing soil P fertilization management in agricultural ecosystems based on the bioavailability and critical levels for leaching of P fractions.

Soil acidity and phosphorus deficiency are some of the constraints hampering agricultural production in tropical regions. The prevalence of soil acidity is associated with phosphorus (P) insufficiency and aluminum saturation. We conducted a two-seasons experiment to evaluate soil phosphorus availability and exchangeable aluminum in response to phosphate rock and organic inputs in acidic humic nitisols . The field experiment was installed in Tharaka Nithi County in the Central Highlands of Kenya. The experimental design was a randomized complete block design with treatments replicated thrice. The treatments were: Green manure ( Tithonia diversifolia Hemsl.) (60 kg P ha −1 ), phosphate rock (60 kg P ha −1 ), goat manure (60 kg P ha −1 ), Tithonia diversifolia (20 kg P ha −1 ) combined with phosphate rock (40 kg P ha −1 ), manure (20 kg P ha −1 ) combined with phosphate rock (40 kg P ha −1 ), Triple Super Phosphate combined with Calcium Ammonium Nitrate (TSP + CAN) (60 kg P ha −1 ) and a control (no input). During the long rains of the 2018 season (LR2018), Tithonia diversifolia + phosphate rock had a significantly higher reduction (67%) of exchangeable aluminum than the sole use of Tithonia diversifolia. Grain yield under TSP + CAN was the highest, followed by the sole organics during the LR2018. Tithonia diversifolia + phosphate rock resulted in a 99% and a 90% increase in NaHCO 3 -Pi compared to sole phosphate rock and sole Tithonia diversifolia, respectively. Tithonia diversifolia led to 14% and 62% higher resin-Pi and NaOH-Pi, respectively, compared to manure in the short rains of 2017 (SR2017). The increase in NaOH-Po after the two seasons was statistically significant in sole TSP + CAN. Based on the observed reduced exchangeable aluminum and additional nutrients like Ca, Mg, and K in the soil, sole organic inputs or in combination with phosphate rock treatments are feasible alternatives for sustaining soil phosphorus. Our findings underscore an integrated approach utilizing organic amendments combined with phosphate rock in acidic humic nitisols' phosphorus nutrient management .

“…In agroecosystems, the content, availability, and dynamics of soil P are largely determined by anthropogenic activities. Long‐term phosphate fertilizer inputs significantly increased the Olsen‐P content in soil (Milić et al., 2019). BRT analysis also showed that the contribution of phosphate fertilizer input to Olsen‐P content was highest (Figure 6).…”

“…(2016) and Milić et al. (2019) who demonstrated that the continual application of manure significantly contributed to the excessive accumulation of P in soil layers of 0–40 cm, which threatened the underground water quality. Organic acids in applied organic fertilizers can help activate the P in soil and reduce the adsorption of P by the soil so that the P has greater mobility to move down to deeper soil layers (Sharpley et al., 2004).…”

Background Phosphorus (P) deficiency in acidic red soil restricts crop yield. However, long‐term application of phosphate fertilizer can cause potential environmental risks due to the accumulation of P in the soil. Aims Our aim was to determine the distribution characteristics of P fractions in acidic red soil profiles and the environmental risk of soil P losses after application of organic fertilizer and lime, and analyze the key factors driving P distribution in the soil profile of acidic red soil. Methods Based on the long‑term applicationof fertilizers and quicklime in the acidic soil under wheat–maize rotation system, contents of soil Olsen‐P and CaCl2‐P, as well as pH, at multiple soil layers between 0 and 50 cm depths were monitored. The environmental critical P levels were determined using a two‐segment linear model. Results During 1990–2010 and 2011–2014, application of phosphate fertilizer or quicklime on acidic red soil significantly (p < 0.05) increased the annual average aboveground biomass of wheat and maize and P recovery efficiency. Soil Olsen‐P and CaCl2‐P contents increased with the application of phosphate fertilizer, especially in combination with manure, and the increase mainly concentrated at the 0–20‐cm soil layer. The environmental critical Olsen‐P content was 99.7 mg kg−1. The Olsen‐P contents at different soil layers were mainly affected by cumulative P and organic P inputs, but were less affected by soil pH. Conclusions The application of organic fertilizer and lime can prevent the acidification of red soil, and the application of organic fertilizer should reduce the total phosphate fertilizer input to prevent rapid accumulation of P and risk of P loss in leachate while still improving the crop utilization rate of P fertilizer. Thus, this strategy should help achieve the concomitant goals of high crop yield and environmental protection.
