Fertilizer spreader

The Fertilizer Spreader is designed for the distribution of solid mineral fertilizers, which are formulated into granules or, less commonly, crystals or powder, but some types are also suitable for distribution of manure in small pellets and, inappropriately, for the distribution of seeds in the seed broadcaster.

There are two basic types of fertilizer, a spin or pneumatic action.
The Fertilizer Spreaders is the type centrifugal cheaper and more widely used. It consists of a hopper cone-shaped or pyramid upside down, dropping by gravity manure on a rotating platform driven by the PTO of the tractor. As a result of centrifugal force, the fertilizer that falls on the platform is hurled back in range, covering the progress of the tractor with a rectangular band. The dosage of the fertilizer is made by adjusting the exhaust port of the hopper and the speed of the tractor. The system is relatively vague in both the dose distribution homogeneity is, however, these limits are acceptable and more than offset by the low cost of the machine, a tractor expert is able to operate overlapping bands resulting homogeneity of distribution and adjusting the speed to the amount of fertilizer to be administered in a single step. The centrifugal spreaders are suitable for the distribution of crystalline or granular fertilizer pellets, while they are ill-suited to the distribution of fertilizer powder (such as basic slag and old formulations of calcium). In any case, the powder formulations have become a marginal distribution and are mostly used for soluble fertilizers.
The Fertilizer Spreaders tire is a type more sophisticated and less widespread. It consists of a hopper which drops the fertilizer in a stream of forced air which conveys it through pipes to the distribution system. This is basically made up of a cross bar which are distributed in the discharge nozzles. Compared to centrifugal spreader has the advantage of better regulate the distribution and does not require the overlap of the steps in the distribution itself is homogeneous. The operating limitations consist of the formula used: pneumatic conveying is suitable because the distribution of fertilizers in powder or granules, and is poorly suited to the granules, crystals and, a fortiori, to the pellet.

The capacity of the hopper to the working width, up to the precision in the distribution, a quick glance at the latest solutions on the market

The Fertilizer spreader is essential equipment in the country and companies offering solutions for the wide audience of professional farmers and not forgetting the occasional equipment to the contractors. It can be seen in the case of machinery for contractors, a tendency to increase the capacity of the hoppers to promote better work efficiency.
At the same time seeking to increase the working width, continuously improve the accuracy of the broadcaster with studies of granular fertilizer applied to ballistics. The adroitness and technical improvements on the machines tend to increase work efficiency with a special focus on environmental effects. The Fertilizer spreader is equipment that can be accurate, but not particularly technical aids, but only mechanical, when used under conditions suitable for soil-atmosphere and the models developed and tested by the manufacturers. In the market there are some companies that offer systems applicable to precision farming fertilizer: These electronic control systems provide the ability to precisely manage the distribution with the aid of maps and GPS system, allowing to distribute the fertilizer to be accurate to broadcaster is using the preset quantity according to the needs of the crop and soil physicochemical characteristics.
Other companies deploy electronic control units controlled by the precision of the distribution, while a fine precision mechanics compatible with high quality broadcaster. One of the strengths of all companies operating in the market is represented by the excellent choice of materials (stainless steel), from construction to art machine, the use of tires and a large section of the application systems to prevent losses on the edge of the plots.
These characteristics are the trump card of companies to look to new markets and to export the best of the manufacturer.
Before the review, a brief note of the market. For the Italian market after two years’ growth, the data estimated in 2009 speak of a decline of 4.5%.
A market that still sees a predominance of those models have drawn up and which has as striking as the proportion destined for export by almost 90% on a production of about 60 thousand units per year.
