The Fertiliser Directory: Materials Guide - Tapa blanda

Reseña del editor

The FERTILISER Directory has been designed to help you find the information you require in seconds. All products are laid out on separate pages in full colour using a common style throughout. A-Z referencing makes it simple to use. Effective fertiliser use is a key to farm profits, and about half the output of crops and intensively managed grassland is generated by fertiliser application. Despite this, the general knowledge of fertilisers and the nutrient sources they contain is sometimes less good than it should be. Over 70 fertiliser materials are featured ranging from ammonium nitrate to zinc sulphate. Contents: Key Nurients; Common Terms; Main Fertilisers; Physical form; Recommendations; Useful data.
