Manure involves the decomposition of so-called “dead biomass”. For example, fresh nettle is mixed with water in a barrel or barrel and left to stand in a warm place for a few weeks, preferably in the garden in the sun. A fermentation process takes place in which microorganisms decompose the plant parts and active plant substances, such as nitrogen, are released and the PH value also increases. If you use it, the plants can absorb nutrients very well and can also be protected from pests and fungal attacks. Now there are various plants that are suitable for producing your own manure. Today we would like to introduce you to the popular nettle manure and comfrey manure.

You can find these edible wild plants now in JulyHow is nettle manure prepared?
To make it, there is a classic recipe in which you put 1 kilogram of cut nettle or comfrey in a barrel with 10 liters of water. All parts of the plant should be covered with water. During the fermentation process, a very strong odor will emanate from the manure. If you want to counteract this phenomenon, you can initially add some rock dust. The container is then covered with a grid or a bag. However, air should still be able to pass through so that the resulting gases can escape. Now the mixture is fermented for about 2 weeks. You should stir vigorously every day.
After 14 days you can use the manure. If bubbles still appear during stirring, it could be a sign that the fermentation process has not yet finished, in which case it is advisable to wait a few more days. When the manure is ready for use, the required quantity is sieved and the manure is diluted with water. In this case the 1:10 ratio proved effective. So 1 part manure and 10 parts water. If the manure was not diluted it would be too intense and could damage the plants. Here it is said that plants could «burn». It is best to apply manure in the morning or on cloudy days, but not on very hot, sunny days. The soil is fertilized and even leaves that are not eaten can be sprayed with manure.
