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(yǎng)分過度損耗及土壤酸化,改善施肥技術以提高養(yǎng)分吸收,減少養(yǎng)分流失,從而全面改善作物生產。
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(xiàn)有的大量研究表明,酸雨對土壤生態(tài)系統(tǒng)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(yǎng)、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。
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(yè)生態(tài)與社會、經濟的持續(xù)發(fā)展意義重大,而gis在土壤肥力質量評判中發(fā)揮日益重要的作用。本文首先基于gis支持下,運用地統(tǒng)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(xiàn)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(xù)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。
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(yè)對保障我國糧食安全發(fā)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(xiàn),導致的以土壤養(yǎng)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(xiàn)形式的土壤物理、化學和生物學退化,給生態(tài)系統(tǒng)本身與環(huán)境都帶來了巨大壓力和嚴重威脅。

百科解釋
Soil acidification is the buildup of hydrogen cations, also called protons, reducing the soil pH. This happens when a proton donor is added to the soil.
