Role of Mulching and Solarization
in weed management
 Weeds are plants which are underliable in a
particular
 Situation and there removal is a source of
economic
 Social ,aesthetic and a medical relief for human
being.
 Mulch is a German word which derived from
molsch.
 It means beginning to decay.
 Mulch is a thin layer of any substance that is
spread over the soil.
 Mulching is a soil and water conserving and
weed management practice through soil
solarization in which any suitable material is
used to spread over the ground between rows
of crops or around tree trunks .
 Mulch reduces sun heat damage.
 It suppresses weed growth.
 Retain moisture.
 Reduce soil erosion.
 Provide soil nutrients
 Encourage beneficial soil microorganisms.
 Decrease water evaporation.
 Mulch blocks sunlight, it prevents some
seeds from germinating.
 Slugs, Earwigs, Cutworms, other pests love
dark, cool, moist places.
1. Low light intensity
2. Most seeds do not germinate
3. Or kill at seedling stage
4. There is lack of photosynthetic activity.
5. Overheating
 Aluminum foil or Painted mulch
 Plastic mulch
 Degradable mulch
 Stone mulch

Role of mulching and solarization in weed management
Advantages
 Increased yield of numerous crops mostly
vegetables.
 It repels the aphids and thrips.
 When vector insects repelled, transmission of
viruses is also reduced.
Disadvantages
 Not used on large scale.
 Hard to lay
 Very expensive
 Sometimes caused physical damage to plants
when come in contact with it.
Role of mulching and solarization in weed management
Advantages
 Black plastic mulch increase the soil
temperature up to 4-5℉.
 Eliminate weeds problems .
 Red mulch increase tomato yields.
Disadvantages
 Some insects like aphids, thrips, and
whiteflies attracted to black plastic
 Influence of mulch color on crops is highly
specific .
Role of mulching and solarization in weed management
Advantages
 It used before the plastics were developed.
 Can be turn into soil at the end of season.
Disadvantages
 Paper mulches may degrade too quickly.
 Tend to degrade early especially around
edges that are in the soil.
 Windy conditions hinder complicate
installation.
 Mixed results in terms of yields.
1. Straw mulch
2. Bark mulch
3. Wood mulch
4. Compost mulch
5. Cocoa mulch
6. Leaf mulch

 It is also called solar soil heating.
 Soil solarization is the act of using the solar energy
of the sun used to kill weeds and soil borne
diseases.
 Soil solarization can be done by anchoring :
 A piece of plastic to the ground
That increased the soil temperature
And kill pests or weeds.
 It is effective against weeds which are
produced from seeds.
 Soil covered with thin transparent plastic
sheets of 20-25 mm.
 Polyethylene film used during hot summer
months for 2-4 weeks.
 This increases the temperature by 10-12 C*.
 Weeds seeds desiccated present at top 5cm.
 Example : Philaris minor, Avena and broad
leaves.

Role of mulching and solarization in weed management

  • 1. Presentation Topic: Role of Mulching and Solarization in weed management
  • 2.  Weeds are plants which are underliable in a particular  Situation and there removal is a source of economic  Social ,aesthetic and a medical relief for human being.
  • 3.  Mulch is a German word which derived from molsch.  It means beginning to decay.  Mulch is a thin layer of any substance that is spread over the soil.
  • 4.  Mulching is a soil and water conserving and weed management practice through soil solarization in which any suitable material is used to spread over the ground between rows of crops or around tree trunks .
  • 5.  Mulch reduces sun heat damage.  It suppresses weed growth.  Retain moisture.  Reduce soil erosion.  Provide soil nutrients  Encourage beneficial soil microorganisms.  Decrease water evaporation.
  • 6.  Mulch blocks sunlight, it prevents some seeds from germinating.  Slugs, Earwigs, Cutworms, other pests love dark, cool, moist places.
  • 7. 1. Low light intensity 2. Most seeds do not germinate 3. Or kill at seedling stage 4. There is lack of photosynthetic activity. 5. Overheating
  • 8.  Aluminum foil or Painted mulch  Plastic mulch  Degradable mulch  Stone mulch
  • 12. Advantages  Increased yield of numerous crops mostly vegetables.  It repels the aphids and thrips.  When vector insects repelled, transmission of viruses is also reduced.
  • 13. Disadvantages  Not used on large scale.  Hard to lay  Very expensive  Sometimes caused physical damage to plants when come in contact with it.
  • 15. Advantages  Black plastic mulch increase the soil temperature up to 4-5℉.  Eliminate weeds problems .  Red mulch increase tomato yields.
  • 16. Disadvantages  Some insects like aphids, thrips, and whiteflies attracted to black plastic  Influence of mulch color on crops is highly specific .
  • 18. Advantages  It used before the plastics were developed.  Can be turn into soil at the end of season.
  • 19. Disadvantages  Paper mulches may degrade too quickly.  Tend to degrade early especially around edges that are in the soil.  Windy conditions hinder complicate installation.  Mixed results in terms of yields.
  • 20. 1. Straw mulch 2. Bark mulch 3. Wood mulch 4. Compost mulch 5. Cocoa mulch 6. Leaf mulch
  • 26.  It is also called solar soil heating.  Soil solarization is the act of using the solar energy of the sun used to kill weeds and soil borne diseases.  Soil solarization can be done by anchoring :  A piece of plastic to the ground That increased the soil temperature And kill pests or weeds.
  • 27.  It is effective against weeds which are produced from seeds.  Soil covered with thin transparent plastic sheets of 20-25 mm.  Polyethylene film used during hot summer months for 2-4 weeks.  This increases the temperature by 10-12 C*.  Weeds seeds desiccated present at top 5cm.  Example : Philaris minor, Avena and broad leaves.
