Effects of long-term storage of soil sample on some chemical properties on vertisol
Effects of sample storage methods on the PH, Total Nitrogen and available phosphorus are done for 24 month/two years. As well as the interaction between sample storage time and storage material done. The highest average concentration of PH is Month 18 (6.204) and the lowest average concentration is moth 24(6.090). The highest mean concentration of Total Nitrogen on month 1 (0.0875%) and lowest mean concentration on month 12(0.0633%) table. This result indicates Total Nitrogen has decreased from months 1-24. The highest mean concentration of available phosphorus on month 3(5.6726 mg/kg) and lowest mean concentration on month 24(3.3385 mg/kg). The availability of phosphorus in stored soil sample is increased from months 1- 6, but decreased from month 12-24.Soil sample storage has an effect on PH, total Nitrogen and available phosphorus.
