现代农业专题系列314——营养元素11【第一期】

贫瘠的土地开不出美丽的花朵，植物的生长需要养料。养分亏缺会导致作物产量降低或土壤养分耗竭。然而过度施肥又会引发环境危机，如温室气体排放，土壤板结、污染水源等。因此，农田中营养元素的盈亏与农业生产和环境效应密切相关。目前，农田养分盈亏已经成为全球最大的粮食与农业数据库FAOSTAT中的最新板块。本期专题归纳整理了近期有关农业营养元素的相关报道，主要针对碳、氮、磷、钾等营养元素展开讨论。

本次营养元素专栏共计三期，本期为第一期，未来还有更多主题专栏推送，欢迎关注“现代农业 Modern Agriculture”公众号，期待后续精彩内容。也欢迎大家积极参与现代农业主题相关的原创稿件投稿，优秀稿件将被刊发在相应专题中，获选者还有精美礼品相赠。
