N-Freisetzung aus organischen Handelsdüngern – Übersicht und eigene Versuchsergebnisse im ökologischen Gemüsebau. [N-Mineralisation of organic fertilizer - Review and own results in organic vegetable production]

Anfang der 90er Jahre setzte eine intensive Feld-Versuchstätigkeit zu Fragen der N-Düngung mit organischen Handelsdüngern ein. Dabei wurde in erster Linie, zumeist unter ökologischen Anbaubedingungen, die Ertragswirksamkeit verschiedener Dünger miteinander verglichen. Ergebnisse von Brutversuchen geben erste Hinweise auf das Mineralisationsverhalten, das unter Feldbedingungen bis dato kaum untersucht wurde. Hierzu werden eigene Versuchsergebnisse im Kontext mit den verfügbaren Literaturdaten vorgestellt

Women\u27s Resistance to Apartheid

They were forced into overcrowded cities whose pollution and poverty caused the death of many, made to work for wages that could barely keep one individual alive , let alone an entire family, and given no opportunity to better themselves through a decent education. These horrific conditions ultimately resulted in a struggle of resistance against the system by many individuals of South Africa.

Even more surprising is the fact that this group of women consisted not only of black women but also white women
