  3. These examples show that, contrary to the widely accepted assumption that nutrient inputs to tropical upland soils will accelerate acidification and deterioration, a combination of supportive management measures such as erosion control, legume cropping and recycling of biomass and plant nutrient inputs can safely lead to soil fertility buildup and attractive, sustainable, economic returns

    通常認為在熱帶地旱土土壤上施用養分會加速酸化和土壤退化，但這些例子卻恰恰相反，表明了通過控制水土流失、種植豆科作物、生物量再循環以及養分投入等綜合配套措施可以穩妥地增進土壤肥力和獲得有吸引力的經濟效益。
  4. Agricultural intensification plays an important role in stabilizing the food production in china, while bringing about an increasing negative impact on the soil and eco - environment as a result of the long - term highly - intensive land use and agricultural chemical overuse, thus leading to degradation of soil physical, chemical and biological properties, which are demonstrated as soil nutrient imbalance, soil acidification, pollutant accumulation, and biodiversity deterioration and posing serious stress and threat to the ecosystem per se and the environment

    摘要集約化農業對保障我國糧食安全發揮了巨大的作用，但其長期的土地高強度利用和農用化學品過量投入的負面影響也日益顯現，導致的以土壤養分失衡、土壤酸化、有害物質積累、生物多樣性衰退等為主要表現形式的土壤物理、化學和生物學退化，給生態系統本身與環境都帶來了巨大壓力和嚴重威脅。
  5. The average soil fertility rose in the north china plain and mid - lower yangtze river regions, and decreased in the northeast. additionally, although the north china plain saw an improvement in soil ph - value, acidification of the soil increased in the other regions

    土壤肥力數據的分析結果表明，樣本總體而言，從80年代初到2000年，除土壤速效鉀下降和土壤酸堿性有所退化外，農業上壤的有機質、全氮和速效磷平均含量都增加了。
  6. Study on the characteristic and cause of vegetable soil acidification in the area of southern jiangsu province

    蘇南菜地土壤酸化特點及成因分析
  7. So far, most related researches and achievements have showed that acid rain has certain impact on functions of a soil ecosystem. such as leaching of soil base - exchangeable ions, heavy metals and microelements, nitrogen, contents of sulfur and phosphorus nutrients, soil acidification, population and activities of soil microbes, soil buffer capacity, soil sensitivity to acid rain, soil structure and weathering status of soil minerals, and so on

    現有的大量研究表明，酸雨對土壤生態系統的功能特性，包括土壤的鹽基離子以及重金屬與微量元素的淋溶、土壤營養、土壤酸化、土壤微生物數量及其活性、土壤緩沖性能、土壤對酸雨的敏感性、土壤結構、土壤礦物風化等方面均會產生一定的影響。
  8. This article, with the help of gis, first uses geostatistics to study temporal and spatial changing of soil fertility factors, such as oganic matter total n total p, total k available k available p ph and cec, in wujin city in nearly 20 years, and draws these conclusions : soil acidification of large area exists in the city, the content of n is generally lower but it tends to rise, the content of p and k is lower and it ' s still lowering, the content of organic matter is medium but it tends to add, cec ' s quality grade is higher but its content is lowering

    土壤肥力質量時空演變對于農業生態與社會、經濟的持續發展意義重大，而gis在土壤肥力質量評判中發揮日益重要的作用。本文首先基於gis支持下，運用地統計學，研究了武進市近20年全n 、全p 、全k 、有效p 、有效k 、 ph 、 cec和有機質等土壤肥力要素的時空分異狀況，得出：存在大面積土壤酸化現象、 n素含量總體較差但趨于提高、 p素和k素含量較低且繼續降低、有機質含量中等但有增加趨勢、 cec質量等級較高但含量趨下降。
  9. Moreover, it means improvements in fertilizer use efficiency such as a better nutrient balance to counter depletion of soil nutrients and soil acidification, better application techniques to improve nutrient uptake and to reduce nutrient losses, and overall improvements of crop husbandry

    更確切地說：是要通過平衡施肥提高肥料利用率和防止土壤養分過度損耗及土壤酸化，改善施肥技術以提高養分吸收，減少養分流失，從而全面改善作物生產。
