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...
متن کاملInfluence of long-term application of organic and inorganic fertilizers on soil properties
This study assesses the effect of long-term (59 years) application of organic and inorganic fertilizers on soil organic matter and enzyme activity. Total organic C, total organic N, hot water soluble C, microbial biomass C and dehydrogenase activity were evaluated in soil from the long-term field experiment in Prague-Ruzyně (Orthic Luvisol, clay loam). Total organic C and N increased significan...
متن کاملBacterial 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...
متن کاملDRIS Evaluation of the Nutritional Status of Crisphead Lettuce
Diagnosis and Recommendation Integrated System (DRIS) norms were derived for crisphead lettuce (Lactuca sativa L.) from field fertility experiments conducted over the past 20 years on mineral and organic soils in Florida. Preliminary testing indicates that DRIS diagnoses generally agree with diagnoses using the sufficiency range approach, with the advantage of predicting the degree of nutrient ...
متن کاملSoil 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...
