“…The acidic soils pose a severe challenge for pea cultivation due to the high availability of aluminum (Al), iron (Fe), and manganese (Mn), which can be toxic to the plants (Bojórquez-Quintal et al, 2017). The high availability of Fe and Al also leads to low availability of certain essential elements such as phosphorus, calcium, magnesium, and molybdenum (Vyas et al, 2007;Dambrine, 2018). Moreover, pea plants have high phosphorus requirements for nodule formation and its function and optimum photosynthesis (Powers and Thavarajah, 2019).…”

Rhizosphere microbiome significantly influences plant growth and productivity. Legume crops such as pea have often been used as a rotation crop along with rice cultivation in long-term conservation agriculture experiments in the acidic soils of the northeast region of India. It is essential to understand how the pea plant influences the soil communities and shapes its rhizosphere microbiome. It is also expected that the longterm application of nutrients and tillage practices may also have a lasting effect on the rhizosphere and soil communities. In this study, we estimated the bacterial communities by 16S rRNA gene amplicon sequencing of pea rhizosphere and bulk soils from a longterm experiment with multiple nutrient management practices and different tillage history. We also used Tax4Fun to predict the functions of bacterial communities. Quantitative polymerase chain reaction (qPCR) was used to estimate the abundance of total bacterial and members of Firmicutes in the rhizosphere and bulk soils. The results showed that bacterial diversity was significantly higher in the rhizosphere in comparison to bulk soils. A higher abundance of Proteobacteria was recorded in the rhizosphere, whereas the bulk soils have higher proportions of Firmicutes. At the genus level, proportions of Rhizobium, Pseudomonas, Pantoea, Nitrobacter, Enterobacter, and Sphingomonas were significantly higher in the rhizosphere. At the same time, Massilia, Paenibacillus, and Planomicrobium were more abundant in the bulk soils. Higher abundance of genes reported for plant growth promotion and several other genes, including iron complex outer membrane receptor, cobalt-zinc-cadmium resistance, sigma-70 factor, and ribonuclease E, was predicted in the rhizosphere samples in comparison to bulk soils, indicating that the pea plants shape their rhizosphere microbiome, plausibly to meet its requirements for nutrient uptake and stress amelioration.

“…Among the key indicators of soil health are pH and exchangeable aluminum concentration, both of which play vital roles in determining soil productivity and crop yield. The concentration of hydrogen ions in the soil determines the pH, which represents the acidity or alkalinity of the soil solution [ 2 , 3 ]. It influences the availability of essential nutrients to plants, as well as the activity of microorganisms that play a crucial role in soil fertility.…”

“…If the pH is lower than 5 it is important to implement practices to increase its value (Ryant et al, 2016). Soil acidification frequently occurs in warm and humid climates, with high precipitation levels (Dambrine, 2018).…”

Objective: evaluate the effect of the inclusion of lime and dolomite soil amendments in an established pasture of perennial ryegrass (Lolium perenne) cv. Tetragrain associated with white clover (Trifolium repens) cv. Ladino and red clover (Trifolium pratense) cv. Kendall. Methodology: Three treatments of soil amendments were implemented on a perennial ryegrass with white and red clover pasture A split plot experimental design was used. The treatments were: T1= control treatment (without soil amendment), T2= lime and T3= dolomite. The evaluated variables were: herbage mass (HM), dry matter (DM), neutral detergent fiber (NDF), acid detergent fiber (ADF), crude protein (CP), in vitro dry matter digestibility (IVDMD) and estimated metabolizable energy (eME). Results: There were significant differences in all evaluated variables, the interaction between experimental periods and treatments was not significant for any variable. The treatments did not affect herbage mass. As for the the soil, a decrease in pH is observed at the end of the experiment, and there was an increase in the total soluble calcium, magnesium and nitrogen and a decrease in aluminum. Implications: This study illustrates the use of soil amendments, which somehow modulate effects of the farmer practices on the pasture soils. Conclusions: Inclusion of soil amendments in pastures did not increase dry matter production, content of FDN, FDA or IVDMD, but increased crude protein and evaluated minerals, and decreases aluminum.
