Lignosulfonate is used in agriculture as an analogue of humic substances. As a soil conditioner, it is mainly used to enhance the absorption and retention of fertilizers and other nutrients. [7] It is able to chelate minerals while remaining bio-degradable, an improvement compared to EDTA. [8]
Marl has been used as a soil conditioner and neutralizing agent for acid soil [13] [17] and in the manufacture of Portland cement. [18] Because some marls have a very low permeability , they have been exploited for construction of the Channel Tunnel between England and France and are being investigated for the storage of nuclear waste .
Soil bulk density, when determined at standardized moisture conditions, is an estimate of soil compaction. [3] Soil porosity consists of the void part of the soil volume and is occupied by gases or water. Soil consistency is the ability of soil materials to stick together. Soil temperature and colour are self-defining.
Soil sealing or soil surface sealing is the loss of soil resources due to the covering of land for housing, roads or other construction work. [1] Covering or replacing the topsoil with impervious materials like asphalt and cement as a result of urban development and infrastructure construction paired with compaction of the underlying soil layers results in the mostly irreversible loss of ...
