全球范围内磷的流向和形态

磷(P)在全球范围内的流向对维护人类和生态体系的健康至关重要。但是人类对它们的流向和在土壤中的累积认知各不相同,这就导致了在如何管理与使用P有关问题的见解不同。这篇文章试图厘清我们对P流向已知和未知的问题。只有这样做了,我们才有可能了解到P的状况以及如何提高对它的管理。 最近在美国华盛顿特区召开的专题讨论会上,一些科学家讨论了P的可持续性 .

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 .

良好的营养是植物健康的关键

Rob Mikkelsen著, 谢玲 译 涂仕华 校 想要获得作物高产,良好的开端是关键。在其作物生长的早期阶段,幼苗特别容易受到多种环境和生物胁迫的影响。为了使作物免受环境胁迫和病害困扰,从播种到收获都必须保证均衡营养。随着我们对植物健康前沿研究的不断深入和了解,植株营养和抗病性之间的关键联系也更加清晰可见。本文可提供以下一些例证: 钾 钾在植物很多人们熟o.

磷足迹的含意是什么?

Tom Bruulsema著, 谢玲 译 涂仕华 校 足迹可以讲故事。它可以追溯你曾经去过哪里。现在人们越来越多地使用碳和水的足迹来追溯气候变化及水源短缺历史。同时人们也引入了磷在食物中的足迹。足迹和效率都被用作农业可持续性的检验标准。但是它们既可能把人们弄糊涂,也可能让人们受到启迪。为了明白正确道理,我们必须懂得这些标准。 足迹可以描述资源消耗或是环境影 .

土壤残留磷与4R养分管理

Tom Bruulsema著, 谢玲 译 涂仕华 校 磷养育着整个世界。如果把磷肥从农业生产中拿走,世界粮食生产会受多大损失呢?答案却决于磷缺失的时间长度,但我们现有的数据仅仅来自有限的几个长期田间定位试验。美国堪萨斯州一个40年的长期试验发现,不施磷肥处理的玉米产量降低27%,高粱产量降低10%。在英国洛桑实验站,25年不施磷肥的小麦产量降低44%。在很多热带土壤上,作 .

变量施用磷肥对你有什么好处?

Steve Phillips著, 谢玲 译 涂仕华 校 很多农田土壤磷测试值(STP) 的空间变异性很大,这会影响作物产量。田间养分空间变异性是由于土壤类型、地形、耕作历史和其它因素的变化决定的。常规措施如采取复合土样以及统一施肥量都会忽略空间变异性从而导致肥料利用率低,这是因为统一施肥量会引起田间某些区域的施肥量不足或过量。 磷肥变量施用与统一施肥量相比有多种好 .

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 .
