Fertilize with coffee grounds
The residues of the preparation of our daily coffees, which often without thinking we throw in the wet, are a rich source of organic substance and mineral salts that should not be wasted. The coffee grounds are rich in minerals, in particular: nitrogen, calcium, nitrogen, potassium and magnesium; an organic mixed fertilizer for all purposes.
Among other things, this fertilizer at no cost is an excellent soil improver and very useful to integrate with the ash as it tends to lower the pH of your soil. Because of its peculiarities this fertilizer is especially suitable for flowering plants but it is also very good for vegetables or aromatic plants that grow in the balcony or terrace.
If we reflect, considering how much coffee we consume in our families, we will have an average of one year (if we consume only one coffee maker a day with two or three cups) we can accumulate something like 20-30 grams of moisture for 365 days: it is equivalent to 7 , 3 – 10.95 kg of fertilizer per year. If you eat coffee twice a day, the amount doubles.
The only precaution to be taken before their contribution is to make them dry slightly important (placing them in a glass or terracotta container) in order to prevent moisture from causing mold.
As mentioned, the usefulness of coffee grounds in addition to lowering the pH of too alkaline soils, is that they are suitable for acidophilous plants; on the other hand, precisely for this reason the coffee grounds are avoided for plants that instead of acid soils prefer the calcareous / basic ones; they can also be used as an ecological repellent to remove different types of parasites (ants and snails).
Another way to use the coffee grounds is to store 20 gr of coffee grounds in a bucket of water, leaving it all in infusion, to obtain a liquid fertilizer and an excellent nourishment for the plants.
Clearly the coffee grounds can be integrated with other organic products to improve the quantity and quality of the compost.
