Question

Disadvantages with traditional crop yield prediction

Answer 1

Answer:

Disadvantages of traditional cultivation

• Traditional methods use simple tools only.

• When farmers have burned the brush and cleared the field, they cannot prepare the soil properly, because they use only a hoe.

• They can only scratch the earth and mix the ashes into the soil.

• Like this, farmers cannot get a good harvest.
• Brush fires ruin the soil.

• Fire destroys the organic matter. It is true that the ashes enrich the soil, but the burned vegetation produces no humus and does not improve the soil structure.

• Fire leaves the soil bare: erosion is more severe.

• The soil is not loosened.

• Water and air do not penetrate into the soil.

• Roots cannot go deep enough into the soil to take up water and mineral salts.
