Prices of food crops shot up and then fell quickly in 2008, but with favorable climatic conditions in many parts of the world, a record cereal harvest is expected. At IPI, we believe that another important reason for this record harvest was that many farmers invested in their production systems while commodity prices were high.
However, high prices for food crops do not change the basic requirement to use resources efficiently. Fertigation is one of the advanced tools for achieving large savings of both water and nutrients and, in recent years, IPI has initiated several field experiments with fertigation systems, focusing on potassium management. In this e-ifc edition we provide a detailed report of our IPI-NATESC apple fertigation experiment in China
