7、Inorganic nitrogen source contributed to produce unsaturated fatty acid and organic nitrogen source contributed the cell growth of M14.
11、Results showed that soil total nitrogen and organic nitrogen fractions were significantly influenced by long-term application of chemical fertilizer and manure.
15、The wastewater of hexanolactam (nylon) fiber production in Shijiazhuang Synthetic Fiber manufactory is high concentrated with organic nitrogen compounds.
19、Based on field fertilizer experiment of cotton under drip irrigation in the area, cotton nitrogen diagnosis and nitrogen fertilizer recommendation with soil inorganic nitrogen quick test was st.
3、Soil soluble organic nitrogen in different horticultural production systems
8、Nitrate and water-soluble organic nitrogen were migrated with deionised water migrating and increased subsoil fertility.
13、The correlation between soil microbes and soil organic carbon was negative, and the correlation between number of fungi and soil organic nitrogen was positive.
18、Maize straw returning to the field can increase the soil total nitrogen and inorganic nitrogen content.
4、Addition of sludge can reduce the loss of organic nitrogen and total nitrogen during MSW composting.
10、Organic nitrogen was useful for better growth of the mycelium, but inorganic nitrogen, NH4NO3 and (NH4) 2so4 was contribute to higher HA content in weight of the mycelium.
17、The results showed that when organic nitrogen fertilizer was applied, the plant height was lower and leaves were smaller, while the photosynthetic rate was higher in the latter stage of growth.
5、Ammonium assimilation is a very important process to transform inorganic nitrogen into organic nitrogen for plants.
14、With the application of the organic manure, the organic nitrogen is the main pattern of the water-solution nitrogen loss, of which the average occupies more than 60-70%.
2、The relationship of organic carbon and organic nitrogen is positive.
16、The application of organic fertilizer is necessary in supplying the resource of potassium of soils and alleviating the disequilibrium of N,P,K and increasing the use efficiency of organic nitrogen.
9、The nitrogen, which is in ammonium in the ammonia sulfite pulping waste liquor of rice straw, is converted into organic nitrogen by using oxide-ammonium decomposition method.
6、The relationships between available nitrogen values determined by various chemical methods and different organic nitrogen components were different.
12、Due to higher content of protein in chondroitin sulfate wastewater and low measured value of ammonia nitrogen, organic nitrogen was neglected in designing wastewater treatment process.
