Influences on Soil Nitrogen Mineralization: Implications for Soil Restoration and Revegetation

Influence of Soil on Nitrogen Mineralization: Impact on Soil Recovery and Vegetation Recovery Introduction Nitrogen is a major nutrient essential for plant growth and is one of the nutrients lacking in most soils. Inadequate soil nitrogen levels available limit the microbial growth as well as the disintegration and growth of the plant itself. Re-establishing the flow of nitrogen in the soil is important for attempts to restore vegetation, as place disruption can adversely affect the flow of nitrogen through the soil - plant - microbial system.

Nitrogen leaching is a serious ecological problem due to water pollution. Mineralization of soil organic nitrogen, especially nitrification of nitrogen fertilizer, is one of the main reasons for nitrogen enrichment in soil. Biological nitrification inhibition (BNI) has gradually become the main target for studying plant nitrification. Research has shown that plant nitrification inhibitors (NIS) are the first choice for soil nitrification management in recent years. For example, a biological nitrification inhibitor (BNIS) is an allelic chemical that can suppress nitrification of soil. Wheat Allelochemicals such as ferulic acid, p-hydroxybenzoic acid, hydroxamic acid, etc., act on soil microorganisms, suppress soil nitrification, reduce N 2 O emissions, increase nitrogen use efficiency, and reduce environmental pollution (Ma, 2005).

Inadequate soil nitrogen levels available limit the microbial growth as well as the disintegration and growth of the plant itself. - Management of Soil Fertility About 2 billion hectares of land, accounting for 17% of the Earth's total vegetation area since 1945, have deteriorated for agriculture (Oldeman et al., 1990). Alderman et al. (1990) While about half of this devastated area is still classified as available for agriculture, productivity drops sharply and the rest of agriculture is deemed impossible

In addition to nitrogen, most phytonutrients come from minerals that make up the soil parent substance. Part of the nitrogen comes from rainwater such as dilute nitric acid and ammonia, but most of the nitrogen is available in the soil for bacterial nitrogen fixation. Once entering the soil - plant system, most nutrients are recycled through organic, plant and microbial residue (soil organic matter), mineral binding type and soil solution. Living microorganisms and soil organic matter are important for this recycling and are therefore important for soil formation and soil fertility. The activity of microorganisms in the soil releases nutrients from minerals and organic substances for use by plants and other microorganisms, segregates living cells, volatilizes from cells, or leaches out of the soil. loss
