How to prepare the rice field for planting

landprep-wetpreparation-1Land preparation is important to ensure that the rice field is ready for planting. A well-prepared field controls weeds, recycles plant nutrients, and provides a soft soil mass for transplanting and a suitable soil surface for direct seeding.

Land preparation covers a wide range of practices from zero-tillage or minimum tillage which minimizes soil disturbance through to a totally 'puddled' soil which actually destroys soil structure.

It typically involves (1) plowing to "till" or dig-up, mix, and overturn the soil; (2) harrowing to break the soil clods into smaller mass and incorporate plant residue, and (3) leveling the field.

Initial land preparation begins after your last harvest or during fallow period. This is important for effective weed control and for enriching the soil. Generally, it will take 3−4 weeks to prepare the field before planting.

Different rice ecosystems have different land preparation requirements. Lowland rice fields, for example, are usually puddled to develop a hard pan and reduce water loss. Upland ricefields, on the other hand, do not necessarily have to be puddled. In resource-limiting environments, dry preparation can be adapted.

Wet Preparation

Wet Preparation

Wet preparation may be appropriate if...

  • My farm has access to irrigation.
  • My field is surrounded by bunds that enable flooding.
  • My farm has a loamy to clay type of soil.
  • I have equipment for primary tillage, secondary tillage, and leveling.

Dry Preparation

Dry Preparation

Dry preparation may be appropriate if...

  • I do not have access to irrigation and water supply is limited.
  • I have equipment and machinery available for tillage and/or labor is a limiting factor.
  • My farm has a coarse, sandy type of soil.
  • My field has a well-established hard pan, I have planted rice on it many times and I can control weeds with methods other than flooding.
