There are alot of layers for damaged soil.
what are the needs for soil compaction and the factors affecting it ?
Bearing capacity of soil
It would seem to suggest the level of compaction of the top layers of soil. Rainfall, decomposition of organic matter and the overall composition of the soil (abundance of clay acts as an impermeable) will be major influences in compaction or settlement of the layers.
Soil compaction creates a physical barrier to plant roots' growth in their search for more nutrients. More of the plant's energy is used up trying to push roots through this harder layer of soil.
Loamy soil is the most desired soil structure.
Compaction is the process by which loose soils are applied to a construction site and densified. The objective of compaction is to remove air voids from the soil. The degree of compaction of a soil is expressed in terms of its dry density ρ d or dry unit weight γ d (These measure grain packing.)
Soil compaction affects plant growth because if the soil is more compact it is harder for air, sunlight, and water to get to the roots of the plant.
improve the drainage or compaction characteristics of soil

yes

Type your answer here...It depend of on the following things;- Acidity and alkalinity of the soil and compaction of the soil.
