Dry preparation is typically practiced for upland rice, but can also be done for lowland fields.
In this method, the soils are not puddled and there is no freestanding water in the field. It requires less water and is effective for soil aeration, and in controlling golden apple snails.
It also helps to obtain a smooth and firm seedbed, control weeds, and incorporate organic materials and fertilizer into the soil.
Dry preparation is a good option when labor and water are scarce or when you require a short turn around time between crops.
Dry cultivation can reduce soil fertility and should only be practiced where wet land preparation is not an option.
The following are the steps and processes involved in dry preparation:
Other techniques in dry land preparation include:
This technique is effective in reducing the weed seedbank in the soil.
In this practice, the field is tilled and leveled, and then weeds are allowed to emerge before being killed by using a non-selective herbicide or. Depending on weed population and soil condition, no further tillage may be required.
