How important is lime for agriculture?
A large area of the Brazilian soil features a high content of acidity. As a consequence, it causes low absorption of essential nutrients by the plant roots and limits the production potential. Soil acidity varies according to the characteristics and natural processes. Aluminium is the main element in the soil and when it has acidity, it is available for the plants to prevent the plant root growth.
To correct the soil, the lime is an ally since it features agents that make the aluminium neutralized, and consequently, provides more phosphorus and potassium. The neutralization occurs when the pH is within the ideal range for each crop plant which is usually from 5.5 to 6.5. Thereby, the nutrients are easily absorbed by the plant roots.
Lime application is management that delivers a fertile soil profile. As a result, it provides the proper growth of the plant roots and boosts the yield.
The higher efficient and uniform the application, the better the results are. The required rates for the Brazilian soil vary from 1,000 to 6,000 kg/ha. It can be even higher in new areas where the soil has never received a proper correction. The required amount may vary inside the same field. For this reason, the farmer can use a variable rate to apply the required rate according to the maps created for applications.
This management is required every two or three years since the soil has natural processes for acidity formation. The main processes are decomposition of organic matter, application of nitrogen and acid rain. For this reason, follow the soil conditions closely.
Another relevant point to applying lime is the solubility. In other words, the time the solution takes to produce an effect on the soil and varying according to the lime type applied. Especially in relation to the particle size. Products named as filler by the Brazilian regulation feature a higher efficiency in relation to the response time. However, as it is a light product, it can be easily carried by the wind and demands more attention when applied.
To ensure an efficient and uniform spreading, Stara provides spreaders by gravity – Bruttus 12000 and Bruttus 25000. It delivers great application quality, and the variation is below 8%. It may vary according to the product and weather conditions. Since it spreads by gravity, powdered product applications are provided with low drift.
Bruttus 12000 and 25000 are the only transportable spreaders by gravity in the world. It features an articulated chassis that allows the sections to be folded for transport on narrow roadways, bridges and across narrow gates. The wheelset system with a rocker arm allows for greater terrain copying during spreading operations. In addition to the wheelsets being mounted beneath the hopper, which eases access for reloading, Bruttus 12000 is equipped with high-flotation tyres that avoid soil compaction.
The section shutdown, besides reducing overlap, avoids the waste of products and provides higher savings during applications. The Bruttus spreader line features a rubber conveyor belt that provides greater spreading precision. Another advantage is the roller scraper that ensures that the system is cleaned easily and fast, consequently providing the system with a longer lifespan.
Among the embedded technologies are the automatic section shutdown and variable rate application. They are compatible with Syncro and Telemetria Stara. Bruttus 12000 and Bruttus 25000 ensure optimum spreading by gravity to correct the soil and increase the crop field yield.
