Balancing guava nutrition with liming and fertilization

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...

Methane and Nitrous Oxide Fluxes in an Acid Oxisol in Western Puerto Rico: Effects of Tillage, Liming and Fertilization

ÐChanges in land use and management of tropical systems are considered to be major factors in the recent upsurge in increases in atmospheric nitrous oxide (N2O) and methane (CH4). Studies were initiated in western Puerto Rico grasslands to determine the e€ect of plowing, or liming and fertilizing an acid Oxisol on the soil±atmosphere exchanges of N2O and CH4. Weekly ®eld ̄ux measurements and ®el...
