Soil entry

As bottom entry or entry in which is Soil Science and environmental protection the storage of undesirable substances referred to in the soil structure. The transport or the accumulation of these fine substances, heavy metals, fertilizers and acidic components takes place mainly through water (precipitation, groundwater) and through wind:

• Sedimentation and suspension as well as precipitation
• Aeolian sediment and emissions .

The often critical today acid furnish by rainwater see soil acidification -can partly by chemical buffer areas of the bottom ( H ⁺ - ion ) prevents or greatly attenuated. The over-fertilization - which can be counteracted by regular soil analyzes - and excessive nutrient input , which also adversely affects the chemistry of nearby water bodies , are often more serious .
