“…The application of calcitic or dolomitic limestone increased the soil pH in the 0–0.10 m layer in comparison with the control in both experiments. Increasing pH is the main purpose of applying lime (Cai et al, 2022; Holland et al, 2019; Nahar et al, 2022). After limestone is applied, the pH rises because of reactions with CO 2 from the soil atmosphere and water, forming hydrogencarbonate that neutralizes the exchangeable and residual soil acidity, releasing CO 2 into the atmosphere.…”

In acid soils, when no‐tillage farmers intend to apply lime, the question arises as to whether it should be incorporated into the soil or whether it can be left on the soil surface. In this study, two types of limestone, calcitic (Lcal) and dolomitic (Lmag), were tested in two olive groves of cv. Cobrançosa, with an initial pH of 4.9 (S. Pedro) and 5.5 (Raparigas). In S. Pedro, limestone was incorporated into the soil (Lburied) and in Raparigas it was left on the floor (Lfloor). The use of limestone significantly increased soil pH in the 0‐0.10 m layer in both experiments. In the 0.10‐0.20 m soil layer, only Lmag increased significantly the soil pH in comparison to the control. Lmag was more effective than Lcal in increasing cation exchange capacity (CEC) and reducing exchangeable acidity (EA) and aluminum (Al3+) in the Lfloor experiment. Both limes increased leaf calcium (Ca) concentration, and Lmag increased the leaf levels of magnesium (Mg). In Lfloor experiment (higher soil pH), soil microbial carbon (C) decreased, and microbial nitrogen (N) increased with liming, which may indicate an increase in bacteria in the soil and a decrease in fungi. In Lburied experiment (initial pH of 4.9), liming significantly increased accumulated (2018‐2021) olive yield (56 and more than 67 kg tree−1, respectively, in the control and liming treatments). In Lfloor experiment (initial pH of 5.5), the accumulated olive yields did not differ significantly between treatments (average values between 105 and 115 kg tree−1). The results of this study provide evidence that liming may increase olive yield in very acid soils and that dolomitic limestone should preferably be used by no‐tillage farmers, due its higher solubility and faster effect on soil and trees.

“…

Soil acidity is an important ecological factor affecting crop productivity worldwide (Nahar et al, 2022;Wakwoya et al, 2022;Wen et al, 2022). For agricultural purposes, acid soils are considered those that have a pH value of less than 5.5 for most of the year (FAO, 2023).

“…Metagenomic sequencing has revealed the effect of different soil types on the composition of seedling microbiomes (Walsh et al, 2021 ). For example, soil pH and organic matter have been identified as the primary environmental drivers in shaping the microbial communities of seedlings in wheat and rice and the rhizosphere in Oplopanax elatus (Li et al, 2022 ; Nahar et al, 2022 ). In fact, it has been demonstrated that total carbon, available potassium, available phosphorus, aluminium, pH and total nitrogen might all affect the rice seed microbiome due to significant impact on the rhizosphere microbiome (Zhou et al, 2020 ).…”

The scientific community increasingly recognized that seed microbiomes are important for plant growth and nutrition. The versatile roles and modulating properties that microbiomes hold in the context of seeds seem to be an inherited approach to avert adverse conditions. These discoveries attracted extensive interest, especially in staple food crops (SFCs) where grain was consumed as food. Along with the rapid expansion of population and industrialization that posed a severe challenge to the yield of SFCs, microbiologists and botanists began to explore and engineer seed microbiomes, for safer and more fruitful grain production. To utilize seed microbiomes, we present an overall review of the most updated scientific literature on three representative SFCs (wheat, rice and maize) using the 5W1H (Which, Where, What, Why, When and How) method that provides a comprehensive understanding of the issue. These include which factors determine the composition of seed microbiomes? Where do seed microbiomes come from? What are these seed microbes? Why do these microbes choose seeds as their destination and when do microbes settle down and become seed communists? In addition, how do seed microbiomes work and can be manipulated effectively? Therefore, answering the aforementioned questions regarding SFCs seed microbiomes remain fundamental in bridging endophytic research gaps and harnessing their ecological services.
