農讀S2EP.02：氮肥用越多、產量就越高？拆解PFPN氮肥偏生產力，5招提升施肥效率
from 農.讀 · host 阿德
氮肥用量與作物產量並非線性關係，而是一條先升後降的曲線——過量施肥不但無法增產，還會讓肥料利用率大幅崩跌。這集阿德帶大家認識「氮肥偏生產力PFPN」這個關鍵指標，教你如何計算每公斤氮肥能換回多少產量，並整理國際研究實證的五大提升方法：分次施肥、搭配生物刺激素、硝化抑制劑、生物炭，以及有益微生物協同施用，幫助農友在肥料成本上漲的年代，用更少的肥料換到更高的投資報酬率。 有問題找阿德：[email protected] 阿德的社群：https://reurl.cc/3kZX80 歡迎大家加入一起學習分享 -- Hosting provided by SoundOn
