Is caused by a buildup of salts in surface soil layers as a result of too much water?

What is salinization? Salinization is the process by which water-soluble salts accumulate in the soil. Salinization is a resource concern because excess salts hinder the growth of crops by limiting their ability to take up water.

Why are tropical forests so vulnerable to deforestation?

Why are tropical forests so vulnerable to deforestation? Given the low numbers of people living in and around tropical forests, there is not enough pressure to deforest these areas. The fragile tropical soils become infertile and are easily eroded. Tropical soils are better suited for agriculture than forests.

What would a poor farmer in a very poor country most likely do to prevent leaching?

What would a poor farmer in a very poor country most likely do to prevent leaching? The correct answer is – D. The farmer would plant cover crops, leave them to die over the winter, and let them serve as natural fertilizer.

What type of agriculture is the most sustainable?

  1. Permaculture.
  2. Aquaponics & Hydroponics.
  3. Using Renewable Energy Resources.
  4. Crop Rotation & Polycultures.
  5. Trees Can Increase Crop Yields.

This allowed a spike in population and increased health. The new farming techniques also led to an enclosure movement.

Does salt make land infertile?

Large quantities of the salts dissolved in the water, such as sodium and chloride, are diffused into the soil and remain there after the water has evaporated. The salt stunts the crops and can even make soils infertile in the long run. And that is for a reason: “Our crop plants are the result of many years of breeding.

Which of the following is a good way to reduce salinization?

Add organic matter and manure to keep moisture and reduce irrigation. Restrain from deep tillage/heavy machinery not to transfer soil salts to the root zone area, which induces salinization. Use cover crops or mulch to protect the ground surface.

What factors might contribute to how much salt in the soil plants can tolerate?

FACTORS AFFECTING SOIL SALINITY

  • Irrigation water quality – The total amount of dissolved salts in the irrigation water, and their composition, influence the soil salinity.
  • Fertilizers applied – The type and amount of fertilizers applied to soil, affect its salinity.
