About this product
Product Information
Se evaluo la calidad del humus producido por la lombriz roja californiana a partir de tres mezclas de sustratos organicos, mediante la caracterizacion de los cambios fisico-quimicos y microbiologicos durante las etapas de compostaje y vermicompostaje. Se utilizo un diseno de bloques al azar con tres tratamientos y cuatro replicas. Los sustratos se prepararon con estiercol equino mezclado con desechos de vegetales y cocina en las siguientes proporciones: 60% estiercol + 40% desechos de cocina (T1), 60% estiercol + 20% desechos de cocina + 20% desechos de vegetales (T2) y 60% estiercol + 40% desechos de vegetales (T3). Las variables objeto de estudio fueron, pH, materia organica, contenidos de nutrimentos (N, P, Mn, Ca), metales pesados (Cd, Cu, Hg y Pb) cuantificadas en todas las etapas del proceso y, para el caso de los humus se estudio ademas granulometria, calidad microbiologica (expresada en densidad y tipos de microorganismos) y madurez del abono por medio de pruebas de fitotoxicidad. Se encontraron diferencias estadisticamente significativas tanto para los tratamientos como para cada una de las etapas de maduracion de los abonos.

Great item, exactly as described. The packaging was very poor but item arrived undamaged. Communications and dispatch time were also poor but overall a successful transaction.

Pros - polite communication, low prices, generous discount offered for damaged book.
Cons - very slow communication which tends to be generic and promises much but delivers little, heavy book was sent in a jiffy bag and arrived damaged, had to get Ebay involved to action the promised partial refund.
Summary - 'pile it high and sell it cheap' organisation which is unable to provide efficient customer service and makes the mistake of not packaging books correctly. Will not buy from them again.
