“…Both paddy blocks have been experienced with low rice yield due to soft clay soil problems (Nordin et al, 2014). The occurrence of soft clay soil in the study area caused the agricultural machines could not be operated over the field because the soil was not able to resist the mechanical pressure (Nasir et al, 2019). In this study, we used a grid sampling method to collect soft clay soil samples in each paddy block.…”

“…For instance, Hore et al (2020) has successfully created a model for zonation of soft clay soil. Nasir et al (2019) has reported the rubber wheel tractors and half-track tractors can devastate the soil hardpan layer and may cause soft soil spots around the paddy fields. Nordin et al (2014) has recommended the soil replacement technique to improve the soil hardpan layer in the soft clay soil areas.…”

The soft clay soil has been categorized as infertile soil. The occurrence of soft clay soil in paddy field areas can decline soil quality and rice production. Therefore, to find the best technique for amending this soil, this study aimed to analyze the physical, chemical, and microstructure properties of the soft clay soil in the paddy field area. The soft clay soil samples were collected from two paddy blocks in Kedah, Malaysia. The physical and chemical properties of the soil were determined using the standard method in the laboratory. The microstructure properties were analyzed using Zeiss SUPRA 55VP microscopes. The results found that the soft clay soil was composed of silt – clay (> 90%) with the texture of silty clay. The soft clay soil was characterized by low values of organic matter (2.63-3.42%), pH (3.32-3.69), cation exchange capacity (6.89-8.72 cmolc kg-1), available P (0.14-0.41 mg kg-1), aggregate stability (16.53-17.78%), and hydraulic conductivity (0.17 cm hr-1). In contrast, it indicated high values of soil water content (42.24-43.21%), and exchangeable Na+ ions (2.48-2.50 cmolc kg-1). In addition, the analysis of heavy metals content revealed that their concentrations were below the critical level in the soil. The soft clay soil was largely governed by kaolinite minerals, and it had less compact structures with many large voids among soil aggregates. In conclusion, the quality of soft clay soil in the study area was poor with low physical and chemical parameters. The quality of the soil could be improved by the addition of soil amendments such as zeolite, cement, and other additive materials to absorb the excess water in the soil and increase the soil strength.

“…Mechanisation has been credited with boosting the productivity of paddy production, but it has also been accused of contributing to the development of soft soil conditions. Soft soil conditions are characterised by high compressibility and low strength, with a hardpan layer at a soil depth of 30 cm that measures less than 0.3 MPa (Nordin et al, 2014;Rendana et al, 2017). Soft soil condition is caused by the extensive use of heavy field machinery which damages the soil hardpan layer.…”

Mini combine harvesters have been very popular among paddy farmers. The compact size of the machine, in addition to the axial flow threshing mechanism and the effect of low ground pressure on paddy soil, makes it a potential alternative for efficient paddy harvesting of a height-adjustable mini combine harvester used for harvesting paddy fields. This type of harvester was tested in typical paddy field conditions planted with MR297 variety at MARDI Seberang Perai. The performance tests included measuring theoretical and effective field capacity, field efficiency, soil bearing capacity before and after machine disturbance and machine slippage. The fuel consumption was also recorded. The combined harvesting losses were also measured during the experiment. Results showed that in wet and muddy conditions, the mini combine harvester obtained a theoretical field capacity (TFC) of 1.28 ha/hr, effective field capacity (EFC) of 0.94 ha/hr and a field efficiency (FE) of 73.4%. The average fuel consumption of the mini combine harvester was 25 L /ha. The wheel slippage in wet paddy fields was 2.18% and on farm roads was 1.55%. The mini combine harvester also contributed to producing less ground effects, combined with the use of low ground contact pressure tracks, that caused minimal soil disturbance that would affect the soil hardpan layer. This mini combine harvester produced an average harvesting loss of 2.3% with an average harvesting impurity of 10.65%. The mini combine harvester had enough power to move in typical paddy field conditions, with no soft soil problems. The mini combine harvester was able to turn 360 degrees within a small area, which made it suitable for harvesting in paddy fields. Thus, this mini combine harvester has the potential to be used for paddy harvesting with the ability to not only produce minimal harvesting loss, but also produce less ground contact pressure which can help to manage the soil hardpan layer from being easily damaged.

“…Soft soil condition has become a major issue faced by paddy farmers (Taufik et al, 2015). Soft soil is defined as an area with low and inadequate bearing capacity, having less than 0.3 MPa at 30 cm depth, to support the agricultural machineries on it (Ahmad et al, 2020;Fauzi et al,2018;Rendana et al, 2017;Nordin et al, 2014). In 2013, 8000 hectares of soft soil areas were identified in MADA, 4800 hectares in KETARA and 5200 hectares in IADA Kemasin Semerak (Abdullah, 2014).…”

Soft soil condition has become a major problem faced by Malaysian paddy farmers. MARDI has developed mole drain subsoiler and tracked agricultural prime movers to overcome this problem. The objective of this paper is to evaluate the effect of integrating mole drain and tracked prime movers on soft soil area. The mole drain was installed on an identified soft soil area at an experimental plot at the Department of Agriculture (DOA) Station, Kg Bukit Merah, Seberang Perai Tengah, Penang. Tracked prime movers were used for land preparation, transplanting and harvesting. Results showed that the soft soil condition of the plot was reduced to from 79% to 17%, a reduction of 62%.
