Land preparation
refers to the
process of preparing the soil for
planting crops.
-
creates favorable conditions
for seed germination, seedling
growth, and crop management
by reducing weeds and soil
pathogens.
goal of land preparation
-
water retention,
drainage, aeration, and ease of
field operations.
what does land preparation improve
-
Tillage
It involves breaking up, turning, and
loosening the soil to improve its
structure, manage crop residues,
control weeds, and enhance water
infiltration.
-
Tillage
The manipulation of the soil into a
desired condition by mechanical
means; tools are employed to
achieve some desired effect.
-
Primary tillage
Initial soil preparation, such as
plowing, to break up the soil.
-
adequate power
dry
plowing is possible with
-
moist for plowing and stable
enough for traction,
primary tillage is done when the soil is
-
Plowing
to cut soil into furrow
slices and to partly pulverize the soil
(still in cloddy condition)
-
Plowing
to incorporate weeds and
stubble underneath the
soil
-
Secondary tillage
refers to
the tillage operations
performed after primary
tillage to refine the soil for
planting.
-
Secondary tillage
It helps in further breaking up
clods, leveling the field,
controlling weeds, and
improving soil structure for
better seedbed preparation
-
harrowing
done to pulverize the clods left after
plowing and to level the field
-
soil type, weed density, soil moisture content, crops to be grown,
The number of plowing and harrowing depends
on:
-
Circuitous pattern
Used with discs and offset discs, it
follows a continuous loop but leaves a central furrow that's
hard to drain and cultivate.
-
Up and back pattern
Implements run parallel, ensuring
efficiency and even cultivation without furrows. Suitable for
rotavators, harrows, and reversible plows.
-
Gathering pattern
Plowing starts from the center and
moves outward, requiring field measurement. Works with all
plow types.
-
dikes or bunds
in lowland areas these are built to retain water
-
10-20 cm
how deep is the soil to be plowed in lowland areas
-
Puddling
done after 10-14 days of submerging
-
Puddling
it is used to creating a
watertight layer to reduce
water loss and enhance
nutrient retention.
-
submerging
done for for 10−14 days
to soften clods and
decompose organic matter.
-
Leveling
is done using a wooden
plank with a draft animal or small
tractor, requiring 12 days of
water coverage.
-
Dry preparation
is mainly used for
upland crops but can also be applied to
lowland fields with diverse crops.
-
Dry preparation
This method avoids puddling and
standing water, requiring less water
while improving soil aeration.
-
less availability of
phosphorus, potassium, silicon, and
molybdenum.
upland chemical characteristic
-
phosphorus, potassium,
silicon, and molybdenum;
lowland higher available chemicals
