The Effect of Tillage on Soil Compaction and Soil Moisture Content: A Preliminary Study on Paddy Soil in Merlimau, Melaka
Publication Date : 20/06/2019
Soil tillage is an important step before cultivating rice by using equipment to prepare the soil for crop growth. It has many procedures to follow in order to avoid future problem such as lower growth rate and fewer yield, as it affects the nutrients intake. This study was conducted to investigate the effect of soil tillage on the soil compaction and soil moisture before and after ploughing process at paddy field. Hence, this study was to identify the change of soil compaction and soil moisture content in each session of ploughing process and the relationship between soil compaction and soil moisture content after first and second ploughing. A tractor model WM1104 with 110hp did the soil preparation. Both ploughing sessions were using rotary tiller. The penetrometer was used for reading the resistance to penetration and measurement data can be read from the display meter .The average values of soil compaction before and after first and second tillage are 186.94 psi, 162.22 psi and 137.78 psi respectively. There is also show a positive relationship between soil compaction and soil moisture content. The higher soil compaction the lower soil moisture content and vice versa.
