  • Adding sawdust to the planting beds during digging will help retain water longer. Plant roots can obtain moisture in the lower layers from moist wood grains.
  • Pour sawdust over 5cm high between rows and planting beds to prevent weed germination.
  • Putting a layer of sawdust under bushes of zucchini, strawberries, cucumbers, tomatoes, etc. will eliminate contact with the ground, defeating caterpillars.
  • Sawdust mixed with ash or urea, piled between beds and crop rows effectively traps water and removes evaporation from the soil.
  • In frosty weather, pour berry bushes, bulbous crops, rhizomes of trees and shrubs with sawdust. Wood chips will become a reliable protector in winter cultivation.

1.2. Sawdust used in livestock

Not only make fertilizer from sawdust This material is also widely used in animal husbandry. The mixed sawdust composting method is one of the biological models of animal care with many outstanding advantages.
