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(shù)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(chǎn)。
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(shù)量及其活性、土壤緩沖性能、土壤對酸雨的敏感性、土壤結(jié)構(gòu)、土壤礦物風(fēng)化等方面均會產(chǎn)生一定的影響。
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.
