Loamy soil in the garden can have its advantages and disadvantages. So there are quite plants and bushes such as the lilac, the yew or even the magnolia, which does not matter to the heavy and poorly ventilated soil. Less robust plants, shrubs and trees, however, require a lighter and better ventilated soil. For this reason, many gardeners are forced to loosen up the heavy loam soil and improve so that there is the possibility of widespread use.
soil analysisSo that the clay soil can be effectively loosened up and thus also upgraded, you should carry out a soil analysis in the first step. Only then will you be able to determine how high the clay content in the soil really is and how the compact substance can best be broken up. Finally, a more fertile and, above all, more diverse soil should be created, which will significantly expand the possibilities of planting.
A soil analysis can, among other things, be carried out via the green space office, which is located at the site. On the Internet, however, can also find various providers who come from the horticultural industry and therefore bring the appropriate experience. In both cases, a soil sample usually needs to be returned for analysis. The corresponding analysis is then carried out in the laboratory and the evaluation is sent by post. So nobody comes into the garden to check the soil on the spot.
Also the resident garden club could give information about the condition of the soil. Many gardeners have problems with the soil, so you can make good use of their experience for your own "flounder".
In the analysis, not only the soil composition is checked, but also the pH. Another important aspect for later planting.
Tip: Since a soil analysis costs money, it is always advisable to first contact the local green space office. Perhaps such an analysis has already been carried out in the immediate vicinity of the property, so that the values and experiences determined there can be taken over. Otherwise, a price comparison always helps in advance.
Heavy clay soil requires heavy work material for loosening up. So always with a spade, the soil before the planting be dug up. At best, to a depth of 20 cm. This corresponds to a generous spade length. So you make sure that the top layer of the soil is sufficiently loosened up to give the plants and their roots space, air and water to grow. In order to be able to shred the large clods that inevitably result from the digging up, you can then work with a hoe, a cultivator and a rake. Make sure, however, that you do not condense the soil too much again. Finally, a better ventilation and water absorption with the digging is sought.
After digging and mincing the resulting floes, an organic fertilizer should be sprinkled over the soil. This can be cow dung, horse manure or the like. The layer should be at least 5 cm thick. Then the area with the manure is dug up again, so that the manure can mix well with the clay soil. The undermining should take place at least once a year.
For clay soil, October is recommended. This month it is especially humid and the frost has not started yet. In addition, the harvest, with the exception of the winter vegetables, should have already started. If you choose to dig in the fall, this will bring you a decisive advantage. The frost can penetrate the soil so well and loosen it up in a natural way. The so-called Frostgare give your soil so an additional way to recover and loosen up in a completely natural way.
Tip: Good manure is always at the farmers around the corner. They are also happy to deliver the manure so that you do not have to worry about transporting the most unpleasant-smelling material.
The additional treatmentAfter evaluating the soil analysis it must then be decided how the heavy clay soil can be treated further. Compost, gravel, sand or other coarse and always natural fertilizers can be added as an additive. The denser and heavier the ground, the more must be done.
For example, gravel regulates the water balance very well. The same applies to sand. Both materials create air pockets in the ground where the water can collect. The plants can then use it quite comfortably. With natural fertilizers such as compost, you provide your plants with important nutrients that promote the growth process. In addition, the compost can be stored longer in the soil. The nutrients in it are thus available over a long period of time.
Note: Flowers are happy when a mature compost is mixed under the clay soil.Lawn, on the other hand, grows very well on a mixture of sand. And if you want to grow vegetables, then an additional green manure should take place.
Tip: A very heavy and firm loam soil tolerates a larger portion of gravel. This must be dug under until it has mixed well with the soil. Especially carrots, turnips or other plants with thick roots are happy about this soil mixture.
