健康的土壤需要把磷施入土中

Tom Bruulsema著, 谢玲 译 涂仕华 校 今天的保护性耕作体系大大减少了土壤混合。当土壤被铧犁耕作后,土壤表面15-25cm的土壤被翻转,把养分集中的土层、施肥带或施肥点剧烈混合。在一个经常耕作的田间,采集一个3-5cm深的土壤样品的测定结果与采自整个耕层样品的测定结果差不多。 一个两英寸的表土样可以单独测定,以评估土壤分层。 然而,随着保护性耕作系统和免耕系统 .

蔬菜条施磷肥用量减半

4R养分管理案例2 蔬菜条施磷肥用量减半 在英国和欧洲,蔬菜生产中磷肥撒施现象很普遍。这是因为人们通常假定在挖窝或播种前撒施的肥料会均匀分布在地表,而且撒施的N、P、K肥会被作物有效利用。然而,不断增加的证据表明,传统撒施的肥料并不总是一种最好的方法,因为它难以满足多种蔬菜幼苗或移栽苗早期的养分需求。由于蔬菜生长早期气温低,养分移动性差 .
