Indiana has several different filth type dissipate throughout its terrain . Different types of soil are formed by different types of source materials ( such as rock and constitutive matter ) , take issue erosion and weathering patterns , and different ecosystem . The type of soil in a region exerts a great upshot on the type of Agriculture Department that can be done there , if any at all . Indiana is dominate by agriculturally rich dirt , but there are a few neighborhood where the soil is not generative .

Alfisols

Alfisols are by far the most common dirt in Indiana . These soils are form for the most part underneath forest cover in climates vagabond from humid to semiarid . The subsoil is gamy in stiff and nutrients . These soils can be very productive in terms of agriculture , but can deteriorate quickly if not conserved . Erosion is very damaging to these soils .

Mollisols

Mollisols are the second most common soils in Indiana , but are only dominant in the northwesterly corner of the land . These stain form under grasslands and are rich in constitutional matter , derived in the first place from the rotten root of the grasses . They are very rich agriculturally . The soil confine weewee very well and has a delicate , light texture .

Inceptisols

In the southerly part of Indiana there are a few gravid area where inceptisols are prevalent . These soils are undeveloped and can have a wide diverseness of features . broadly speaking they are detect on steep slopes or bedrock that is close to the surface . These soils are young and do not exhibit much grounds of weathering . They are often used more for diversion or watershed than for farming , as evidenced by their strong comportment in the turgid national forests and parks in the southerly component part of the state .

Histosols

Histosols are scattered throughout the northernmost quarter of Indiana . They are gamy in constitutive affair and curb large amount of carbon copy . These soils are present primarily in swamps , deltas or marshes . They do not drain well and continue important wet . Histosols make respectable farming soils when drain , but they will molder quickly .

Entisols

Entisols are quite unexploited and are found primarily in sphere of in high spirits eating away , such as outpouring plains , sand dunes , exorbitant slopes and operose rock . Like the inceptisol order , they are youthful . Nevertheless , they are used for agriculture in many area . In Indiana they can be find in the northeast and southeasterly .
