What are two ways in witch the value of soil can be reduced?
The two ways in which the value of soil can be reduced are: when the soil loses its fertility and when topsoil is lost due to erosion.
How can soil lose its value?
Soil can lose its value in several ways. Two are erosion of topsoil and depletion of nutrients and microorganisms in the soil.

How can a fertile soil lose fertility?
In several ways. It can lose fertility when a crop is grown on it, and removed from the field without replenishing the soil with organic and/or chemical sources of nutrients. It can lose fertility when it erodes. The topsoil is the most fertile part of the soil. It can lose fertility over long periods of time, just by rainwater and snowmelt waters running through it. This slowly leaches out any soluble or partially soluble substances.
What are the ways of preventing soil fertility?
Preventing fertility? Not preventing loss of fertility?Use herbicides copiously, especially broad-spectrum and residual ones.Overstock, so as to cause over-grazing.Promote erosion by clearing trees, over-tilling, etc.Withhold fertiliser, or else over-use fertiliser.Burn stubble etc. to prevent the formation of humus.To promote soil fertility, do the reverse.
How did flooding and rich soil contribute to the fertility of the land and gives rise to farming in mesopotamia?
Flooding in Mesopotamia deposited nutrient-rich silt that replenished the soil, making it fertile for agriculture. The regular flooding also helped to prevent the soil from becoming depleted over time. These conditions, along with access to water from the Tigris and Euphrates rivers, allowed for the development of farming practices in Mesopotamia.
Other ways of preserving soil fertility?
by not using much fertilizers

What can be done to retain the fertility of soil?
The ways to retain the fertility of the soil are crop rotation, animal pasturing (which can be considered fertilizing) and fertilizing either with natural or artificial fertilizers.
What are the other ways of preserving soil fertility?
by avoiding too much use of fertilizer
In what ways do farmers contribute nitrates to the soil?

What ways are two ways that water cycle and water on earth and the water cycle are related to weathering and erosion?
Water cycle removes top soil. It decreases the fertility of soil.
