How does topography influence agriculture?

Soil formation is attributed to the following factors: parent material, climate, biota (organisms), geography, and time, according to scientists.

In Minnesota, these elements interact to create more than 1,108 different soil series. The physical, chemical, and biological features of various soils can have a significant impact on how they should be managed. 

1. Parent Material

Minnesota is a land of young geological soils with a diverse range of parent materials. Minnesota soils have one thing in common: they were produced by the last glacier in the northern United States, which melted 11,000 to 14,000 years ago.

This may seem like a long period, but in terms of soil formation and geology, it is considered recent. Till, loess, lacustrine, outwash, and till over bedrock are the five major parent materials.

2. Climate

Temperature and precipitation have an impact on how quickly parent materials weather and, as a result, on soil qualities like mineral composition and organic matter concentration.

The rate of chemical reactions is directly influenced by temperature. The faster reactions occur as the temperature rises. The physical weathering of rocks is accelerated by temperature changes. 

3. Biota (Organisms)

The development of soil has been profoundly influenced by biotic agents. These include soil-dwelling species like bacteria and gophers, as well as flora sprouting on the surface. 

4. Topography

Slope and aspect are two topography characteristics that have an impact on soil formation. 

Slope

The steepness (in degrees or percent) of a slope from horizontal impacts the amount of soil material deposited or eroded. The most developed soil is level soil, which does not lose or gain material. The slowing of the soil-forming process is due to the change in substance. 

Aspect

Aspect refers to the slope's orientation in relation to the sun (compass direction), which has an impact on how much water travels through the soil. 

5. Time

The fifth factor in soil formation is time. Vegetation and climate have an effect on parent material and terrain over time. The age of a soil is determined by its development rather than its chronological age.

The intensity of the other four soil-forming components determines the degree of age. The following are some of the factors that impede soil formation:

In the parent material, there is a lot of lime.

In the parent material, there is a lot of quartz.

In the parent material, there is a lot of clay.

Parent material is hard rock (resistant to weathering).

There isn't much rain.

Humidity is low. 

The weather is chilly.

Steep slopes.

The water table is very high.

Erosion is severe.

Deposition, accumulation, and mixing by animals or humans continuously.
