Métodos de Amostragem

Floristic sampling: Vegetation sampling: Measurement of soil properties: We randomly selected two subplots within a vegetation relevé, and collected soil samples around 250–500 g within 10 cm in each subplot. The soil samples were mixed and air dried for a week. The air-dried soil samples were filtered with 2 mm mesh filter. Since some of the soil samples contain coral reef stones,  squashing the coral reef stones would increase the soil/sand ratio and calcium concentration, the filtering process were carefully carried out to avoid squashing the coral reef stones. After the preprocessing the soil samples, we measure the following soil properties pH:  Mix air-dried soil samples with deionized water with soil:water = 1:2.5 (w/v ratio). Use orbital shaker to shake for 30 minutes with 180 rpm, then standing for 30 minutes. Use pH meter (Orion 9107BN, Thermo, Massachusetts, USA) to measure the value Rock:soil ratio: Dry the preprocessed soil samples with oven at 250ºC, and calculate the rock > 2 mm ratio   Electrical conductivity: Mix air-dried soil samples with deionized water with soil:water = 1:10 (w/v ratio) Use orbital shaker to shake for 60 minutes with 180 rpm, then filter the soil samples with qualitative filter paper (Advantec No. 2) Measure the soil electrical conductivity (μs cm-1) with conductivity tester (EC30, YSI, Ohio, USA) Elemental analysis, the ratio of total carbon and total nitrogen of soil: use ball mixer mill (MM 400, Retsch Instrument, Haan, Germany) to grind the air-dried soil, then measure the total carbon and total nitrogen content (%) with the elemental analyzer (2400 Series II, Perkin Elmer, Massachusetts, USA) Effective potassium in soil analysis: Extract effective potassium in soil with Mehlich-3 solution (Mehlich, 1984). Then use spectrophotometric molybdenum blue method to measure the effective potassium concentration (mg/kg; Murphy and Riley 1962) in soil with spectrophotometer (V-630, Jasco, Tokyo, Japan) Soil organic matters analysis: dry the soil samples with 550ºC oven for four hours, and calculate the difference after dry (organic matter weight). Then measure the weight of oven-dried soil samples (105ºC, 24 hrs). The soil organic matters (%) is defined as the ratio of organic matter weight and oven-dried soil weight Exchangeable cations (EC) and cation exchange capacity (CEC): Use soil column leaching method to determine CEC with 1M NH4OAc solution (pH = 7.0) 80 ml, and then measure the contents of exchangeable potassium, sodium, calcium and magnesium (cmolc/kg) with atomic absorption spectrometer (SensAA-series atomic absorption spectrometer, GBC, Braeside, Australia) Use soil column leaching method to determine CEC with 1N NH4OAc, and wash out unabsorbed NH4+ solution with 95% Ethanol. Then leaching soil with 80 ml 2M KCL solution to exchange NH4+ absorbed by soil Measure the NH4+ concentration (cmolc/kg) in KCL solution using nitrade combination ISE electrode (HI 4113, Hanna, Michigan, USA) Soil texture (particle size analysis):   Mix 40g filterted soil samples with 100 ml 5% sodium hexametaphosphate, and grinded for five minutes and quantify to 1,000 ml Measure the content of sand, silt and clay with soil hydrometer (ASTM 152H, Chase, New York, USA) and referred soil texture triangle to determine the soil texture
