A healthy and productive sward is the foundation for high-quality basic feed. To keep your grassland crops in the best possible shape, you should do everything you can in the spring to ensure a productive yield with a high energy content.
How does it work? An important first step is to analyse the condition of the grassland area after the winter.
- How much damage has been caused by wild boar or voles?
- How many holes are there?
- How badly affected is the sward?
- Is the field waterlogged or has it been damaged by frost?
- How much of it is covered in weeds?
Once you have assessed the damage, it is time to take steps to resolve it by tilling, cultivating and reseeding. In this process, cultivating serves to first level any mounds of earth created by moles or mice. By contrast, tilling is important because it eliminates dead grass, aerates the sward, and prepares the grassland for reseeding. The reseeding variety and quantity should be decided on based on local conditions and the extent of the damage found. In some cases, using rollers is recommended to press on sward that has frozen solid.
Plan smart for grassland reseeding
With ISARIA, we know how to plan reseeding smartly. Sensor-supported grassland reseeding gives you the opportunity to continually adapt the amounts for reseeding to your crop. One option offered by the ISARIA system is to attach a crop sensor to the front and side mirrors of the cultivating machine. The ISARIA PRO Compact continually records the biomass index and N intake index as it travels over the grassland. These values are used to calculate an output value for reseeding equipment. It doesn’t matter whether it’s after mowing or part of spring maintenance – the areas of the field where the sward has been affected the most should be prioritised. Conversely, areas where growth is intact can be reseeded with a smaller quantity of seeds. The system measures the grassland’s current crop as it moves. This data is used to calculate the seed quantity to be spread, and to regulate the seed dosing according to the data. This will confirm minimum and maximum quantities as well as an average sowing quantity per hectare. This balancing method can help achieve a consistent crop and therefore a homogeneous basic feed for your operations. Establishing energy-rich and high-yield varieties can help you to achieve consistent quality in your crop. This way, you can simplify harvests and silage at the same time – that’s what we call efficient. In addition, stronger grass crops provide more natural competition against weeds. You can then easily manage the data recorded conveniently using our ISARIA CONNECT data management system.
Get the most out of your grassland
In addition to area-specific grassland reseeding, we also recommend area-specific fertilisation. Whether mineral or organic, you can choose whether you want to achieve a consistent crop with the balancing variant, where each area is fertilised evenly according to what it needs, or whether you want to obtain the maximum yields from your grassland using the yield-oriented variants. Apart from this, you can also produce an application map for fertilisation easily from the measurement file in ISARIA CONNECT created during the tilling process. For the yield-oriented variant, you can promote particular areas with a high yield potential. Optimal, area-specific fertilisation affects the quality of your silage. Encouraging areas of your field with high yield potential using adapted fertilisation significantly increases the proportion of high-quality basic feed – and the protein that you produce with the basic feed – it will no longer be necessary to add expensive supplementary feed. Reducing of the amount of crude ash content in the feed offers another decisive advantage. This directly affects the health of your animals. A dense crop makes it possible to stack the mowed grass onto the stubble. As a result, the harvested yield will not come into contact with dirt and sand from the soil. You will therefore introduce less crude ash into your silo during the harvesting process.
