Subsoiler for ridge cultivation

Ridge cultivation

Crops such as maize, oilseed rape and carrots are particularly suitable for growing on ridges. The ridges increase the soil surface considerably. The advantage of the larger soil surface is that more heat enters the soil, especially in spring. This heat makes phosphate more readily available, which results in faster root development.

Improved root development leads to better mineral uptake, earlier and better development of the plant and a faster start to growth. Especially in a cold spring, root development is extremely important for the initial development of the plant. Crops sown on ridges therefore have a considerable advantage.

Because of increasingly extreme weather conditions, the water-storage capacity of the soil is very important.

Removing soil compaction

In addition to heat, moisture also plays an important role. Within the ridge the soil is loose, while in the rows it is less permeable. This reduces evaporation and gives the crops better access to available moisture. In wet conditions, water drainage is improved so that water stays between the rows and the plant stands dry on its ridge. As soil compaction is eliminated, excess rainwater can sink into the soil more easily.

Improved carrying capacity

Ridge cultivation improves the carrying capacity of the soil because deep tillage only takes place between rows. This is important for hoeing and other mechanical operations later in the season.

The seeding combination consists of a specially developed subsoiler with a seed drill behind it, with which the main soil cultivation, including sowing at 75 cm, takes place in one pass. The subsoiler loosens the soil where the rows are placed to a maximum depth of 45 cm. Because the subsoiler tine has a straight shape it does not mix the soil, but eliminates any soil compaction and breaks up hard layers and old plough pans. Cultivation at this depth makes it easy for the crop to root more deeply. The advantage of better root development is that the plant absorbs minerals and moisture better and thus grows better. 

Next two specially developed elements form the sides of the ridge. This way, the previously applied fertilisers end up in the ridge, which has the advantage that they are available for the root system at the right time. Because the soil between the rows is only treated superficially, surface water is drawn into the soil through the ridge. The nutrients are therefore directed to the plant's roots instead of the roots having to search for them. The ridge is firmly consolidated with cast steel rollers, thus ensuring that the ridge holds together well.

Absorption of fertilisers and improved soil life  

Increasingly stringent manure legislation makes optimal use of fertilisers crucial for a good harvest. Superficial tillage between the rows ensures that the carrying capacity of the soil remains intact. Sowing on ridges also increases soil activity and keeps soil life intact better.
