In this occasion, we use two types of fertilizer: Urea 46% and Marte 45. We are going to speak about them below.
- It only has Amide Nitrogen: 46%
- It is black and its granules are 2-4mm.
- We use about 210kg/he.
- Its composition is: Ammoniacal Nitrogen (NH4): 5%.
- Urea Nitrogen: 35%.
- Sulfur (SO3): 12.5%
- We use about 240kg/he
- It is red and its granules are 1-4mm.
These fertilizers are high quality and they are a big source of Nitrogen. They are able to cover slowly, gradualy and progressively all our crops' needs ... specially cereals and garlic. N/SO3 is a mix which can enhance our crops' growth and it allow us to have a better resistance against fungal diseases, drought period,... These fertilizers are available in bulk, bag of 50kg and big bag of 1000kg.
As you can see in my pictures, we are using an AMAZONE ZA-X 902 Perfect centrifugal broadcaster with hopper sizes of 900 litres. In addition the ZA-X 902 can be increased to 1700 litres by adding the extension L 800. These extensions can be retrofitted at any time. The shallow hopper with its steep hopper walls allows a low filling height from 91 cm and guarantees an even fertiliser flow. Easy attachment to the tractor, always level and at a same mounting height. Accurate spread pattern at working widths from 10 m to 18 m,urea up to 15 m. To prevent any corrosion and for high functional safety the entire spreading device (hopper bottom, spreading discs and deflector plate) is made from stainless steel. The spread rate adjustment with its two individual setting shutter slides is located well out of the "dirt range". The Omnia-Set spreading discs with swivelable spreading vanes provide a particularly precise spread pattern. The oil-immersed gearbox is the indestructible heart of this AMAZONE twin disc spreader. The twin hopper design gives optimised steep hopper walls which guarantee a very constant fertiliser flow. The standard hydraulically actuated independent shutter control for either both or individual right hand and left hand side control enables the comfortable operation of the spreade. The folding lockable sieve is fitted as standard to prevent foreign particles getting into the shutter apertures and is particularly useful where fertiliser is stored and loaded in bulk, e. g. with a front loader.
We use it with a configuration of 15m of distance and 12 km/h of speed. Using this configuration we can work on everywhere and in different conditions.
As far as I'm concerned, I think Germany Amazone ZA-X 902 is the best centrifugal broadcaster on the market and possibly one of the most expensive. Amazone distinguishs by high quality in its products and very specially in broadcaster and seed drills.
