2.  LAND PREPRATION
Land preparation is important to ensure that the field is ready
for Planting. A well prepared field controls weeds, recyles,
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 particles from zero-
tillage or minimum tillage which minimizes soil disturbance
through to a totally “puddled” soil which actually destroys
soil structure.
