ABSTRACT

The soils developed from the Ganges sediments in the coastal area of Bangladesh and India extend several thousand hectares and important from the view point of rice cultivation. Phosphorus, one of the important environmental and agricultural element, retention behavior of the Ganges floodplain soils is poorly reported. The objective of this study was to determine maximum phosphorus adsorption capacity (MPAC) and to develop Psat for 13 Ganges Tidal Floodplain soils of Bangladesh. The MPAC value and Psat based on Mehlich-3 extractions were determined. The conventional adsorption equations, such as the Langmuir, Freudlich and Temkin equations were used to describe the P sorption of the studied soils. The MPAC value varied from 1250 to 2000 mg/kg and correlated with EC (r = 0.59, p<0.05) and CEC (r = -0.74, P<0.01). The sorption capacity of the tested soils ranged from 511 to 545 mg/kg and the calculated energy of adsorption of the soils varied from 0.192 to 1.00 μg/mL and it was a positively correlated with clay (r=0.7, p<0.01) and CEC (r = 0.63, p<0.05) but negatively with silt (r= -0.80, p<0.01), pH (H₂O) (r=-0.60, p<0.05) and with MPAC (r=-0.59, p<0.05) values. Phosphorus saturation indices of the studied sample demonstrated a far below the threshold critical limit of 25%.

ABSTRAK

Tanah yang dibangunkan daripada enapan Ganges di pesisir pantai negara Bangladesh dan India menganjur beberapa ribu hektar dan penting daripada sudut pandangan penanaman padi. Fosforus, salah satu unsur penting dalam alam sekitar dan pertanian, tingkah laku penahanan di tanah dataran banjir Ganges telah dilaporkan secara tidak tepat. Objektif kajian ini adalah untuk menentukan kemampuan maksimum penjerapan fosforus (MPAC) dan untuk membangunkan Psat bagi 13 tanah Dataran banjir air pasang surut Ganges di Bangladesh. Nilai MPAC dan Psat berdasarkan pengekstrakan Mehlich-3 telah ditentukan. Persamaan penjerapan konvensional, seperti persamaan Langmuir, Freudlich dan Temkin telah digunakan untuk menggambarkan serapan P daripada tanah yang dikaji. Nilai MPAC berbeza-beza daripada 1250 kepada 2000 mg/kg dan berkorelasi dengan EC (r = 0.59, p<0.05) dan CEC (r =-0.74, P<0.01). Nilai kapasiti serapan tanah yang diuji adalah daripada 511 kepada 545 mg/kg dan tenaga yang dihitung daripada penjerapan tanah berbeza-beza daripada 0.192 kepada 1.00 μg/mL dan ia berkolerasi secara positif dengan tanah liat (r= 0.7, p<0.01) dan CEC (r=0.63, p<0.05) tetapi negatif dengan keladak (r=-0.80, p<0.01), pH (H₂O) (r=-0.60, p<0.05) dan MPAC (r=-0.59, p<0.05). Indeks tepu fosforus sampel yang dikaji menunjukkan ia lebih rendah daripada had kritikal ambang 25%.

Kata kunci: Bangladesh; keupayaan penampanan; penjerapan; persamaan Langmuir; serapan fosforus
