“…In present study, among fertilization treatments, highest soil pH was under NPKSCa treatment that might be due to addition of lime and straw incorporation to the field. Previous studies, observed the positive effect of straw incorporation on soil pH 24 . Positive effects of straw on soil pH might be due to addition of base nutrients through straw incorporation such as Ca and K which increases the soil pH 56 .…”

Low phosphorus use efficiency (PUE) is one of the main problems of acidic soil that limit the crop growth. Therefore, in the present study, we investigated the response of crop yield and PUE to the long-term application of fertilizers and quicklime (CaO) in the acidic soil under wheat–maize rotation system. Treatments included, CK (no fertilization), NP (inorganic nitrogen and P fertilization), NPK (inorganic N, P and potassium fertilization), NPKS (NPK + straw return), NPCa (NP + lime), NPKCa (NPK + lime) and NPKSCa (NPKS + lime). Results showed that, fertilizer without lime treatments, significantly (p ≤ 0.05) decreased soil pH and crop yield, compared to the fertilizer with lime treatments during the period of 2012–2018. Average among years, compared to the CK treatment, wheat grain yield increased by 138%, 213%, 198%, 547%, 688% and 626%, respectively and maize yield increased by 687%, 1887%, 1651%, 2605%, 5047% and 5077%, respectively, under the NP, NPK, NPKS, NPCa, NPKCa and NPKSCa treatments. Lime application significantly increased soil exchangeable base cations (Ca2+ and Mg2+) and decreased Al3+ cation. Compared to the NP treatment, phosphorus use efficiency (PUE) increased by 220%, 212%, 409%, 807% and 795%, respectively, under the NPK, NPKS, NPCa, NPKCa and NPKSCa treatments. Soil pH showed significant negative relationship with exchangeable Al3+ and soil total N. While, soil pH showed significant (p ≤ 0.05) positive relationship with exchangeable Ca2+, PUE and annual crop yield. PUE was highly negatively correlated with soil exchangeable Al3+. In addition, soil exchangeable Ca2+, pH, exchangeable Al3+ and available N were the most influencing factors of crop yield. Therefore, we concluded that lime application is an effective strategy to mitigate soil acidification and to increase PUE through increasing exchangeable base cations and reducing the acidic cations for high crop yield in acidic soil.

“…For example, the application of organic fertilizer can promote the transformation of NaOH-P i and HCl-P i into H 2 O-P i and NaHCO 3 -P i through promoting soil microbial activity, which increased P availability in calcareous soil (Yan et al 2016b;Liang et al 2017). The transformation of P fractions might be limited by several factors, such as soil organic matter (SOM) content and soil pH (Qaswar et al 2020). It is unclear whether organic fertilizer could change H 2 O-P i and NaHCO 3 -P i fractions, especially in saline-alkaline soils.…”

Organic fertilizer could improve soil phosphorus (P) availability and retention capacity, and the intensive management of P nutrition in saline alkaline paddy soil is of great significance to the sustainable development of rice planting. The P fractions and adsorption-desorption characteristic in saline-alkaline soils were evaluated in a 5-year field experiment. Four treatments were designed: (1) NK (255 kg N ha −1 year −1 and 229 kg K ha −1 year −1), (2) NPK (128 kg P 2 O 5 ha −1 year −1 plus NK), (3) NPKC1 (450 kg C ha −1 year −1 plus NPK), and (4) NPKC2 (900 kg C ha −1 year −1 plus NPK). The results showed that, compared with NPK treatment, soil available P (AP) concentration was significantly increased in NPKC1 and NPKC2 treatments. Especially, soil NaHCO 3-P i concentration was increased by 112.4% and 94.6% in NPKC1 and NPKC2 treatments, respectively. And soil organic carbon (SOC) showed similar trend. However, soil pH and electrical conductivity (EC) were decreased in two organic fertilization treatments. The isothermal adsorption experiment showed that the X m values of all treatments were in the order of NPKC1 > NPKC2 > NK > NPK. Correlation analysis showed that X m was positively correlated with SOC and negatively correlated with soil pH. Under the same initial P concentration, the desorption rates in NPKC1 treatment was the lowest, which indicated that low organic fertilizer was more conducive to the soil P retention capacity. Therefore, organic fertilizer application could increase soil P availability and retention capacity, and lower organic fertilizer addition (NPKC1) was better to improve soil P availability and retention capacity in saline-alkaline soils.
