Effects of Different Nitrogen Fertilizer Rates on Soil Magnesium Leaching in Tea Garden
Magnesium (Mg) helps improve tea yield and quality, yet many tea plantations in China commonly exhibit magnesium deficiency. Therefore, studying the mechanisms of Mg2+ leaching in tea plantation soils is of significant importance. This study investigates how nitrogen fertilizer application affects the leaching mechanisms of magnesium in soil through pot experiments. The control group (N0) consisted of pots without tea seedlings and no nitrogen fertilizer solution added, only an equivalent amount of ultrapure water was used. The experimental groups were: N1 (no tea seedlings, 0.75 mmol L− 1 nitrogen), N2 (no tea seedlings, 1.5 mmol L− 1 nitrogen), N3 (no tea seedlings, 3.0 mmol L− 1 nitrogen), TN0 (tea seedlings, no nitrogen), TN1 (tea seedlings, 0.75 mmol L− 1 nitrogen), TN2 (tea seedlings, 1.5 mmol L− 1 nitrogen), and TN3 (tea seedlings, 3.0 mmol L− 1 nitrogen). The results show that the correlation between nitrate nitrogen (NO3−-N), ammonium nitrogen (NH4+-N), and Mg in the soil with tea seedlings is higher than in soil without tea seedlings. This indicates that tea planting promotes the leaching of Mg2+ in the soil. Further investigation revealed that excessive nitrogen application reduces the soil pH, activates aluminum ions (Al3+) in the soil, and competes with Mg2+ for net adsorption sites, further exacerbating the leaching of Mg2+. Additionally, excessive use of nitrogen fertilizer limits the roots’ ability to absorb nutrients, indirectly leading to the leaching of Mg2+. We believe that excessive application of nitrogen fertilizer in tea gardens will exacerbate the leaching of Mg2+ in the soil.
期刊介绍:
The Journal of Soil Science and Plant Nutrition is an international, peer reviewed journal devoted to publishing original research findings in the areas of soil science, plant nutrition, agriculture and environmental science.
Soil sciences submissions may cover physics, chemistry, biology, microbiology, mineralogy, ecology, pedology, soil classification and amelioration.
Plant nutrition and agriculture submissions may include plant production, physiology and metabolism of plants, plant ecology, diversity and sustainability of agricultural systems, organic and inorganic fertilization in relation to their impact on yields, quality of plants and ecological systems, and agroecosystems studies.
Submissions covering soil degradation, environmental pollution, nature conservation, and environmental protection are also welcome.
The journal considers for publication original research articles, technical notes, short communication, and reviews (both voluntary and by invitation), and letters to the editor.
