Zeolite mitigates alternate wetting and drying – Induced potassium depletion and enhances potassium balance in rice paddies: A 6-year field study
Context or problem
Clinoptilolite zeolite, a class of crystalline inorganic porous material, has been shown to provide several benefits in field crops. However, there is limited information on field-aged effects of zeolite in relation to irrigation methods in rice.
Objective or research question
This study aimed to determine field-aged effects of zeolite on soil exchangeable K (SEK) and soil non-exchangeable K (NEK), K leaching, aboveground K uptake, water use efficiency (WUE), apparent K balance (AKB), soil K balance (SKB) and income of paddy field were analyzed under continuous flooding irrigation (CF) and alternate wetting and drying irrigation (AWD).
Methods
We conducted a six-year (2017–2022) field experiment with two irrigation regimes (CF and AWD) as main plots and zeolite addition at the rate of 0 (Z0) and 10 (Z10) t ha−1 as subplots.
Results
The results showed that AWD significantly increased soil NEK (0.65 kg ha−1 in 2022) and decreased AKB2017–2019 (75.11 %), AKB2017–2022 (76.26 %), SKB2017–2019 (4.75 kg ha−1) and SKB2017–2022 (11.25 kg ha−1), respectively. Zeolite addition to paddy fields could decrease K leaching loss, increase soil exchangeable K, K balances and net income endured for six years, especially under AWD. Compared to ICFZ0, IAWDZ0 respectively decreased apparent K balance (AKB2017–2022) and soil K balance (SKB2017–2022) by 19.73 % and 15.09 %. Compared to Z0, Z10 respectively increased AKB2017–2019 and SKB2017–2019 by 48.51 % and 243.61 % and respectively increased AKB2017–2022 and SKB2017–2022 by 47.47 % and 112.87 %. IAWDZ10 has the highest AKB both in 3-yr aged field and 6-yr aged field, the highest soil NEK in 6-yr aged field.
Conclusions
Overall, the combination of zeolite and AWD technology improved K balances and addressed the accelerated deficit of effective K in paddy fields under AWD. These positive effects persisted for 6 years, exceeding the originally observed 3-yr duration, suggesting zeolite has a long-life cycle and potential in rice production systems.
IMplications or significance
zeolite application can mitigate K depletion for at least six years, especially under AWD, promoting sustainable agriculture development and income of paddy field.
