Organic fertilizer - advantages and disadvantages: organic

All plants need nutrients and as these are limited in soil, they have to be re-added to the soil in some way. Normally, nature does this by itself, in which the plant loses its leaves in the fall and these are transformed back into nutrients by earthworms and other creatures. In the natural garden, this also works, if not too much intervention. If the home garden and planters are regularly supplied with compost, all the nutrients are returned to the soil in this way. If, however, apples, pears and vegetables are taken from the home garden, compensation must be provided with additional fertilization. Also in the ornamental garden, this is necessary if the lawn should always be beautiful green, flowering plants should have a lush pile and is not always enough compost at hand.

Which plants are enough for organic fertilization?

Wild plantings can only be supplied with compost, while the addition of mineral fertilizers of wild character would be lost. The rest of the flowers, such as flowering perennials and flowering shrubs such as autumn anemones, aspergillia, columbine, monkshood and so on are supplied with compost and additionally in spring with other organic fertilizers. The same procedure is used in the vegetable garden. If the demands for vegetables are not quite as high, the fertilization with organic material is sufficient here too.

Disadvantage of organic fertilization

Upon addition of organic fertilizer, the release of nutrients is uncontrollable and can not be accurately assessed due to the slow conversion of organics. To remedy acute nutrient deficiencies, traditional fertilization is not suitable. However, there are already in the retailer organic fertilizer in mixed, ready for spreading finished form or in liquid form. It should also be noted that, for example, horn shavings, blood meal, castor meal or bone meal contain only one or two different nutrients. Details are given on the packaging. Often, one to two substances are mixed, so that the exact ratio always depends only on the information provided by the manufacturer.

What does organic fertilizer consist of?

The organic fertilizer consists mainly of animal and vegetable origin. This means that every compost application is an organic fertilization. But horn shavings, horn meal, blood meal and bone meal also made from animal hooves and animal horns. The fresh manure of horse and cattle, which may be applied only in late autumn, is also included. But it is better to compost the manure for 6 months. Pig manure prohibits itself due to the strong unpleasant odor. Also vegetable fumes, for example from nettles, are one of them.

The most important nutrients

The main nutrients for plants are nitrogen, phosphorus, potassium and a little bit of lime and magnesium. Trace elements such as iron, copper, manganese, molybdenum, zinc and boron also belong to a smooth process of cultivation. Nitrogen promotes the growth of shoots and leaves, phosphorus the flower and fruit formation, potash strengthens the cell tissue, so branches and stems. Lime is not important for the plant directly, but for the soil.

The effect of the fertilizer

For direct fertilization, the organic material is not suitable. The nutrients must first be made available by water and soil organisms, and the soil temperature is important. Therefore it takes a comparatively long time until the nutrients can be utilized. The advantage, however, is that the fertilizer lasts for a long time. Horn shavings, for example, take 2-3 years to implement in the soil, something faster with horn meal. However, they can already be used during planting or sowing since there is no danger of burns.

For which plants is the organic fertilizer used?

All organic fertilizer materials can be applied to all garden crops. An over-fertilization is almost impossible, provided that the purchased fertilizer such as horn meal, horn chips and the like, the recommendations are not significantly exceeded. Since organic fertilizer almost does not wash out of the soil, it is considered to be environmentally friendly. For Biog├Ąrtner this type of fertilizer is obligatory and particularly valuable for its natural cultivation. The organic fertilizer is only of limited suitability for vascular culture since the active ingredients must first be converted by the microorganisms living in the soil. Possibly an organic liquid fertilizer is more advantageous here.

Sprays made against pests themselves

Despite loving care of the garden, there is always a problem with pests. Since the organic fertilizer and chemical clubs absolutely do not match, some self-made sprays of natural substances are very effective when used properly.Proper use means that it is not injected in high sunlight, in rainy weather or before a thunderstorm - but that goes without saying. The best and most effective are the morning and evening hours.
Stinging nettle extract against aphidsPour 500 g of fresh nettles (before flowering) into 5 liters of water for twelve to twenty-four hours. Spray undiluted against aphids.
Garlic tea against fungal infections and spider mitesCrush a medium clove of garlic and brew with 1 liter of water. Strain and when the broth is cold, inject undiluted.
Horsetail stock (horsetail) against mildewSoak 150 g of dried or 500 g of fresh horsetail in 5 liters of water for one day, then simmer for 30 minutes, allow to cool, strain and dilute in a 1: 5 ratio. Spray and water the plant with this broth.
Vermouth tea against aphids, leaf beetles and ant racesBrew a teaspoon with 1 liter of water, strain, let cool. Spray undiluted.

Compost heap as fertilizer source

If you own a garden, you should create a compost pile. So you can make organic fertilizer yourself. The compost only contains biodegradable substances. Today there are many compost containers to buy in the trade. Fast composters are very popular, but even the classic compost heap can still be found in many places.
  • It is important not to give cooked food leftovers in the compost and no meat (raw).
  • For kitchen waste, make sure that they are pesticide-free.
  • To aerate the compost, it is enriched with leaves, wood residues and brushwood. Also Kalkmehl is recommended.


Do not forget to mix the different ingredients. It uses the pitchfork or rake. Who wants to save the work, uses a Kugelkomposter. You can just roll it through the garden. So the content is well mixed. The special composter is generally a great thing. Although the purchase price is high (170 euros), but you save a lot of work and rotting goes quickly. The composter has a capacity of 280 liters and a diameter of 80 cm. Particularly favorable are its four lid flaps, which makes it possible to remove the compost very well and the good air circulation, prevents odors and provides moisture inside.

"Organic" is a fertilizer when its components are not present in their pure form, but predominantly of natural waste products - of plant or animal origin - exist. Probably the best known type of organic fertilizer is compost. A compost heap can be found in most gardens. Here we collect all garden waste such as leaves, straw, grass clippings, plant parts and earth residues. From the kitchen, we can enrich this collection with eggshells, potato peels, salad and vegetable waste.
With proper composting - the waste should always be mixed carefully and also kept moist - valuable humus soil is created through the work of countless microorganisms. This, distributed on our beds, completes the natural garden cycle. Examples of organic fertilizers are: manure, guano, bone meal, fish meal, horn shavings, manure, blood meal.
