Liquid feeding : Applyingfertilisers through irrigation systems has many benefits over spraying, explains

摘要

The application of fertilisers through irrigation systems is not new. Dr Ludwig Blaas applied liquid fertilisers through his "trickle" irrigation in 1947 and he formulated the Liquinure range of fertilisers specifically for that method.Applying fertiliser through an irrigation system provides many advantages over conventional spray-irrigation methods, including low labour and energy requirements, continual availability of nutrients at the right levels, safer environmental application methods, more efficient use of applied nutrients by crops and lower production costs. Liquid feeding allows nutrient adjustment to suit crop stage and higher yields can be obtained on marginal land.
