SOIL pH AND LIMING

When crops do not grow well, one of the first question an agronomist is likely to ask is “What is the pH of the soil?” The reason for this question is that soil pH tells us more about a soils ability to produce crops that any other single measurement. A measurement of soil pH is like a doctor’s measurement of a patient’s temperature. It gives an indication something may or may not be wrong, but...

Soil Acidity and Liming

Soil pH, soil acidity, and their effects on plants The pH scale, ranging from 0 to 14, is used to indicate acidity and alkalinity. pH is a measure of the concentration of hydrogen ions (symbol = H) in the water contained in the soil. A pH of 7.0 is neutral, values below 7 are acidic, and those above 7 are alkaline (basic). The lower the pH, the more acid the soil. Each unit pH drop indicates te...

Microbial Response to Soil Liming of Damaged Ecosystems Revealed by Pyrosequencing and Phospholipid Fatty Acid Analyses

AIMS To assess the effects of dolomitic limestone applications on soil microbial communities' dynamics and bacterial and fungal biomass, relative abundance, and diversity in metal reclaimed regions. METHODS AND RESULTS The study was conducted in reclaimed mining sites and metal uncontaminated areas. The limestone applications were performed over 35 years ago. Total microbial biomass was deter...

Bacterial Diversity in Soil in Response to Different Plants, Phosphate Fertilizers and Liming

The diversity of bacterial isolates from soil in response to different plants (control, Brachiaria ruziziensis and Cajanus cajan), fertilization (control, simple superphosphate and rock phosphate) and liming (with and without lime) was evaluated. Phenotypic and physiological characteristics of the isolates were recorded and organized in a file to identify the bacteria. Among the isolates, 95% w...
