Whether early or late potatoes, floury or festkochend - all potato varieties must also be fertilized. How to do it right, we tell you here.
When potatoes from the supermarket you really never know exactly how they were grown and whether it was not used any pesticides. On the other hand, you are always on the safe side if you grow your own potatoes. But to really get the most out of the tuber, you should also give it the right nutrition, in the form of fertilizer.
In itself, the fertilization of all potato varieties is not that difficult, but only if you do some preliminary work and fertilize the soil in the previous year. Here's exactly how to properly fertilize potatoes or the soil before cultivation to get a really good crop yield.
Fertilize soil before potato cultivation
»Apply horse manure:
You lay the foundation for the cultivation of the potatoes already the year before. Potatoes need a lot of nutrients and therefore you should prepare the soil optimally in the previous year. This is best achieved by incorporating mature compost or animal manure. Cover the beds the winter so best with horse manure. In the following spring, simply lift off the layer with the horse manure and work the remainder into the soil.
»Make a green manure
It is also advantageous if you make a green manure before growing the potatoes, as this then sufficient nitrogen in the soil is available. In addition, the subsoil is loosened and nutrients are transported from deeper layers up. Well suited for a green manure are beans, peas, clover, vetches and lupines. Of course, the plants do not survive the winter, but you can simply work them into the soil in spring. That's how you created the perfect substrate for potato cultivation.
Fertilize potatoes during the growth phase
»Use organic / synthetic fertilizer:
After planting the potatoes, it is then about the correct fertilization during the growth phase. Although the tubers are heavy-bodied and need lots of nutrients, you should not overdo it with fertilizer. If you have prepared the soil properly for cultivation, then you do not need to do so much later.
»Use organic fertilizer:
We generally recommend the use of an organic product for fertilization. For example, horn shavings or manure are ideal for this purpose. Although the yields will not be as great as if you were using a synthetic fertilizer, the flavor of the potatoes is much better.
But: organic fertilizer is the vegetables unfortunately not completely available. Microorganisms close this only gradually. Nevertheless, you should always prefer organic fertilizer to artificial manure.
»Use synthetic fertilizer:
Of course you can also use a synthetic fertilizer. However, when using an artificial fertilizer, you can quickly over-fertilize the soil. Not only does this mean that the potatoes can be stored for a shorter period of time, but the aroma can also suffer as a result, and diseases also have an easier time.
You must therefore make sure that all nutrients (nitrogen, sulfur, magnesium, potassium, phosphate) are present in an ideal amount. And that in turn is not so easy to do. You have to do a soil analysis beforehand to find out the optimal mixing ratio of the nutrients. However, this should be done by a specialist, because only this can then put together the perfect fertilizer from the above nutrients.
»Make a crop rotation every 3 to 4 years:
Since the potatoes leach the floor very much, you should always move the bed to a different location in the garden every three to four years. That too is part of fertilization. In addition, it makes sense if you make a foundation of these beds in the meantime and sow here, for example, clover, vetches or lupins.
