“…In Tables 3, 4 and 5, soil available P levels decreased with the incubation time. This result is comparable with the results that reported by Anetor and Akinrinde (2007) and Deraoui et al (2015). Higher P levels were observed in the treatments where only TSP was added than in the treatments where only lime was added.…”

“…In all soil samples where TSP was added, there was an increase in Borax, Olsen and Bray and Kurtz -1 extractable P levels and that was in agreement with other works, in-cluding that of Waigwa et al (2003) and Deraoui et al (2015). In the limed soils with no P addition, too resulted in a small increase in P concentration.…”

An incubation study was conducted to determine the effect of lime (L) as CaCO 3 , and phosphorus (P) as triple super phosphate (TSP) on soil pH, available P, organic matter decomposition, inorganic nitrogen content, and calcium (Ca) content of soil. Three rates of lime equivalent to 0, 1 000, 2 000 kg (CaCO 3) ha-1 and three rates of TSP equivalent to 0, 50 and 100 mg (P) kg-1 were applied in combination as treatments with three replicates. With the increasing rate of lime, soil pH was significantly (p < 0.001) increased. Both lime and TSP had significant effects (p < 0.001) on P availability at three different soil test P extraction methods. Two thousand kg (CaCO 3) ha-1 with 100 mg (P) kg-1 gave the highest available P irrespective of extractant used. Bray and Kurtz-1 method extracted the largest amount of P (5.63-66.69 mg kg-1) while Borax method extracted the smallest amount (3.42-42.42 mg kg-1). Despite the varied ammonium nitrogen (NH 4 +-N) and nitrate nitrogen (NO 3-N) contents, the NH 4 +-N content decreased and NO 3-N content increased in the all treatments when incubation progressed. With the increasing rate of liming, the decomposition of organic matter and the Ca content also increased.

“…The mineral fertilizer, especially Hoagland solution, will contain free phosphates and it will, upon application, be available at once. Free phosphates on the other hand can easily become adsorbed, immobilized or leached out of reach, in a time dependent manner, and the longer it is in solution in high amounts the larger the portion that is unavailable for the plant (Shen et al, 2011;Deraoui et al, 2015;Demiraj et al, 2017). Living algae contain a metabolic active P supply, in form of phosphate contained in the cytosol (Solovchenko et al, 2016), The figure states our hypothesis on how algal biomass will release phosphate from different bound forms (A), including inorganic P, organically bound P and polyphosphates.…”

Wheat Can Access Phosphorus From Algal Biomass as Quickly and Continuously as From Mineral Fertilizer

Algae can efficiently take up excess nutrients from waterways, making them a valuable resource potentially capable of replacing synthesized and mined fertilizers for agriculture. The capacity of algae to fertilize crops has been quantified, but it is not known how the algae-derived nutrients become available to plants. We aimed to address this question: what are the temporal dynamics of plant growth responses to algal biomass? to better propose mechanisms by which plants acquire nutrients from algal biomass and thereby study and promote those processes in future agricultural applications. Data from various sources were transformed and used to reconstruct the nutrient release from the algae Chlorella vulgaris and subsequent uptake by wheat (Triticum aestivum L.) (as reported in Schreiber et al., 2018). Plants had received 0.1x or 1x dried algae or wet algae, or zero, 0.1x or 1x mineral fertilizer calculated from agricultural practices for P application and grown to 55 days in three soils. Contents of P and other nutrients acquired from algae were as high as from mineral fertilizer, but varied based on moisture content and amount of algae applied to soils (by 55 days after sowing plants with 1x mineral fertilizer and 1x dried algae had 5.6 mg P g DWshoot; 2.2-fold more than those with 0 or 0.1x mineral fertilizer, 0.1x dried algae and wet algae, and 1x wet algae). Absolute and relative leaf area growth and estimated P uptake rates showed similar dynamics, indicating that wheat acquires P from algae quickly. A model proposes that algal fertilizer promotes wheat growth after rapid transformation in soil to inorganic nutrients. We conclude theoretically that phosphorus from algal biomass is available to wheat seedlings upon its application and is released gradually over time with minor differences related to moisture content on application. The growth and P uptake kinetics hint at nutrient forms, including N, and biomass stimulation worthy of research to further exploit algae in sustainable agriculture practices. Temporal resolved phenotype analyses in combination with a mass-balance approach is helpful for understanding resource uptake from recycled and biofertilizer sources by plants.

“…Phosphate fertilizer significantly increased pH from 0 to 30 days in the soil. The dissolution of mineral fertilizers in the soil has various effects on soil properties, including pH, whereas P fertilizers tend to decrease pH values (Boukhalfa-Deraoui et al, 2015). Our results indicated that biochar increased the pH of the soil (Jiang et al, 2015).…”

AimsBiochar has been used as an amendment to improve soil fertility and increase crop yield. A pot trial and incubation experiment were conducted to evaluate the effects of combined biochar and phosphate fertilizer applications on changes in soil physiochemical properties, photosynthetic parameters, and plant growth of Brassica napus L. in acidic soil.MethodsBiochar (B) was applied at rates (B0: 0%, B1: 2%, and B2: 4% w/w) to the soil, while phosphorus (P) as KH2PO4 was added at P0: 0 mg kg–1 soil, P1: 100 mg kg–1 soil, and P2: 150 mg kg–1 soil. Non‐amended soil served as the control (Ck).ResultsThe study found that the maximum photochemical quantum yield of photosystem II (Fv/Fm) and non‐photochemical quenching were affected by biochar and P fertilizer treatments. The Fv/Fm was significantly lower in the Ck while the highest in B2P1. Compared to the Ck treatment, the electron transport rate and photosynthetic rate were significantly increased under the application of biochar with P fertilizer. Additionally, malondialdehyde content declined by 68.9% when biochar was added with P fertilizer treatments. Furthermore, the plant P content and plant growth parameters were significantly increased. Biochar with and without P fertilizer treatments increased soil pH significantly, compared to the application of P fertilizer alone. Water‐soluble P decreased with incubation time, while Al‐P decreased significantly by 69.9% and 76.4% under B1 and B2 treatments, respectively, compared to CK.ConclusionThe findings revealed a positive effect of the combined application of biochar with phosphate fertilizer on the growth of oilseed rape in acidic soil.
