“…This is in line with Mathew et al. (2018), in which there was a reduction in soil pH under the influence of P level treatments. The availability of P was low in highly acidic soil and alkaline soil but was available in the range of 6 to 7 (Ara et al., 2018), which is recommended as optimum for availability and uptake by plants.…”

Nutrients’ mineralization‐immobilization in soil is crucial for their management in crop production. An incubation experiment was conducted to study the effects of phosphorus levels on mineralization of phosphorus (P) and potassium (K) under three soil types in laboratory conditions at the National Soil Science Research Center in Nepal with 3 × 4 factorial completely randomized design. Two factors were three soil types (silty clay loam, loam, and sandy loam) and four P levels: 0, 25, 50, and 75 kg P2O5 ha–1. Five incubation periods (1, 30, 60, 90, and 120 d after incubation) were replicated three times with total of 180 experimental units. The P and K mineralization patterns varied with soil types and P levels, with higher fluctuation of P content in silty clay loam soil as compared with loam and sandy loam soil. Phosphorus concentration with application of 25 kg, 50 kg, and 75 kg P2O5 ha–1 after 120 d of incubation were 95.6, 112.2, and 116.6 mg kg–1, respectively, which was 19.65% (25 kg P2O5 ha–1) to 45.93% (75 kg P2O5 ha–1) higher than control. There were four stages of mineralization‐immobilization turnover of Olsen‐P and available K: rapid declining trend up to 30 d, slow rise up to 60 d, rapid mineralization up to 90 d, and then slows down up to 120 d. On average, rapid reduction in soil pH from 6.60 to 5.42 was observed within 120 d of incubation. The study of mineralization of PK and change in pH during incubation could be helpful for predicting nutrient availability and requirement time for crops.

“…The addition of fertiliser showed a decrease in pH and an increase in EC throughout the study compared to unfertilised ( Fig 1 ). Fertiliser is known for increasing acidification and salts, which are some of its environmental shortcomings [ 43 , 44 ]. The application of biochar and fertiliser mixture had higher pH than the fertiliser application.…”

The use of biochar as a soil ameliorant has recently gained momentum. However, its application has been reported to have some adverse effects soon after the pyrolysis process. This study aimed to determine the effect of different biochar ageing methods and fertiliser applications on selected soil properties, growth, and yield of red radish (Raphanus sativus L.). A 2 x 3 factorial arrangement was used in a complete randomised design (CRD) with three replications. The factors were (1) biochar ageing at three levels, i.e., naturally aged biochar (NB), artificially aged biochar (AB), and fresh biochar (FB), and (2) fertiliser at two levels viz fertilised (F) and non-fertilised (NF). A control treatment (without biochar) was also included. Irrespective of the ageing method used, biochar application significantly increased soil pH, while fertiliser application significantly reduced soil pH throughout the experiment. Similarly, biochar application significantly increased soil hydraulic conductivity compared to the control. However, after ten weeks, significantly higher soil hydraulic conductivity was reported in treatments with AB biochar compared to both NB and FB. The application of fertiliser in biochar-amended soils improves the soil’s hydraulic properties and increases radish growth. The study concludes that AB biochar + fertiliser application improves soil properties and growth of radish.

“…Phosphorus significantly increases branches, leaves, fresh and dry weight per plant in cowpea (Abobatta et al, 2023) at 60 kg P2 O3/ha (Namakka et al, 2017;Kiri et al, 2023). Several studies have shown increased tissue P levels with soil availability of P (Balemi & Negisho, 2012;Mathew et al, 2018;Wieczorek et al, 2022). Phosphorus plays an outstanding function in physiological processes of plants (Kalayu, 2019;Wang et al, 2021;Pan et al, 2022;Jančaitienė et al, 2023).…”

Two field experiments were conducted at the Faculty of Agriculture and Agricultural Engineering Research Farm of Abubakar Tafawa Balewa University, Bauchi, between 2006 and 2007 to study the effects of phosphorus (0, 25, 50 kg P/ha) and zinc levels (0, 2.5, 5 kg Zn/ha) on Total Soluble Carbohydrate and Crude Protein of six cowpea varieties namely: IT90K 277, IT93455 1, IT89KD 288, IT97K 568 18, IT90K 82 2 and Kanannado. The objectives of these experiments were to determine which levels of P, Zn and the various interactions of P, Zn, and year that had produced the highest total soluble carbohydrate (TSC) and crude protein (CP) on the grain contents of the cowpea varieties studied and to determine the best varieties in terms of TSC and CP upon the application of these nutrients (P and Zn) in Bauchi, Nigeria. The results revealed that increased levels of P from P0 to P50 significantly increased the CP and TSC contents of the cowpea grains. Similarly, higher Zn levels (2.5 and 5 kgha-1) were observed to have significant effects on TSC and CP contents of the cowpea grains. Interactions of P and Zn were equally observed to significantly affect TSC and CP contents of the cowpea grains. Of all the six (6) cowpea varieties, Kanannado recorded the highest TSC and CP in the cowpea grains. With regard to year, 2006 recorded the highest CP while 2007 had the highest TSC. Higher levels of P and Zn or their associations were recommended for improving TSC and CP contents of the cowpea grains, with emphasis on Kanannado for Bauchi farmers.
