Losing topsoil to erosion contributes to a loss of inherent soil fertility levels of nitrogen, P, K, and thus to a decline in potential crop yield. The addition of manure and fertilizer can supply needed crop nutrients and help offset some loss of inherent fertility caused by soil erosion.
The toxic chemicals present in the soil can decrease soil fertility and therefore decrease in the soil yield. The contaminated soil is then used to produce fruits and vegetables, which lacks quality nutrients and may contain some poisonous substance to cause serious health problems in people consuming them.
This type of front behaves like a warm front only that it is quiescent because the front barely shifts its position. The weather may also be similar to that of a warm front. The two abutting air masses run almost parallel to the front because none is stronger than the other to cause displacement.
