“…The application of RP is not suitable for the improvement of P concentrations in calcareous soils. Mineral P provides nutrition for the early growth of sugarcane as compared to organic P [21]. Pongrac et al [22] found that transport energy and food storage by crop leaf also depends on the concentration of P in leaves.…”

In calcareous soils, wheat productivity is much lower due to improper nutrient management, especially phosphorus (P). Therefore, this study was conducted to manage P availability from various organic (Control, FYM and Sugar cane straw applied at the rate of 10 ton ha−1) and inorganic (Control, 100% rock phosphate (RP), 50% acidulated RP, 100% acidulated RP, single super phosphate (SSP) and diammonium phosphate (DAP)) sources applied at the rate of 90 kg P2O5 ha−1 in calcareous soil while using wheat as test crop. When averaged across the organic sources, SSP performed better in emergence m−2 (126), tillers m−2 (431), spikes m−2 (419), grains spikes−1 (61), plant height (95.1 cm), 1000-GW (40 g), biological yield (11,023 kg ha−1), grain yield (4022 kg ha−1), phosphorus use efficiency (10.5%), phosphorus in leaves at tillering (2.63 mg kg−1) and anthesis stage (2.50 mg kg−1), soil P at heading (1.73 mg kg−1) and post-harvest stage (1.56 mg kg−1) compared to the rest of the mineral sources. Similarly, among the organic sources, FYM performed better than others for all tested traits. Integration of inorganic P sources with organic manures further improved crop performance and post-harvest soil P content. Therefore, using 10 tons FYM ha−1 in integration to SSP or 100% acidulated RP at the rate of 90 kg P2O5 ha−1 is recommended for ensuring optimum wheat productivity under calcareous soils.

Purpose The high salt content in soil decreases soil structure and fertility. We inquired the effects of manure combined phosphorus (P) fertilizer on the soil organic carbon (SOC) stock, soil aggregate stability and P availability in coastal saline-alkali soil. Methods A 2-year field experiment was arranged with manure and P fertilization in saline-alkaline soil of Yellow River Delta including: four manure treatments (C0, C1, C2 and C3, which was 0, 500, 1000 and 2000 kg C ha− 1, respectively) under two P fertilization levels (P1 and P2, which was 105 and 75 kg P ha− 1, respectively). Results Compared with C0 treatment, soil available P (AP) and microbial P in C2 treatment was significantly increased under the two P levels (p < 0.05). Under same C treatment, optimized P application did not significantly reduce soil AP pool. Under the two P levels, compared with C0 treatment, the mean weight diameter and > 0.25 mm aggregates proportion were significantly increased in C2 treatment (p < 0.05). As the binder for macroaggregates formation, SOC stock was increased by 5.98% and 5.11% in P1C2 and P2C2 treatments, respectively. And humus content increased with manure application. The fulvic acid (FA) content in C3 treatment was highest. However, the humin (HU) content in C2 treatment was highest. This might be because the increase of FA improved the activity of microorganisms and decomposed part of HU. Soil physicochemical properties were increased with manure application. Conclusions Appropriate manure and optimized P fertilizer was conducive P availability, increased aggregate stability and SOC stock.
