Organic fertilizer

Organic fertilizer

Introduction

Fertilizers are substances that serve to nourish both the soil and plants. In this sense, the term coincides with that of "fertilizer", although fertilizers may include different types of substances with corrective and amending effects of the chemical and physical composition of the soil. The main distinction of fertilizers is between organic and mineral or chemical. The former are derived exclusively from the decomposition of organic matter, while the latter, from industrial-derived chemical compounds. Organic fertilizers are now highly sought after in agriculture and gardening, due to their low or zero environmental impact and their healthiness on plants and soil quality. Organic fertilizers can also be obtained from the maceration, grinding and manual processing of certain organic compounds. In any case, the classification of organic fertilizer remains unchanged, both for the one existing in nature and for the worked one. To be defined "organic" it is enough that the fertilizer is obtained and obtained from organic substances present in nature.


Property

Organic fertilizer, as mentioned in the previous paragraph, derives from natural decomposition or from the processing of organic matter. Organic fertilizers include compost, humus, algae, guano (seabird droppings), peat, wet acids and natural fertilizer (manure or manure and pellets). Organic fertilizers have a lower concentration of nutrients than chemical ones, but with the advantage of greater and slower penetration into the soil, penetration that allows you to maintain a good nutritional balance of the soil and plants. In this sense, the organic fertilizer it can be defined as a slow release fertilizer. The combination of the various nutritional and corrective elements also exerts an excellent amending action on the physical and chemical properties of the soil, avoiding pollution from chemical fertilizers and accumulations of water deposits. The organic fertilizer has, in fact, the property of reducing water excesses in the soil and in the roots of plants, always maintaining the right degree of humidity suitable for healthy plant growth.

Advantages

Organic fertilizer is certainly more advantageous than chemical fertilizer, but not in terms of costs, but rather in terms of respect and healthiness of the environment. The organic fertilizer avoids the excesses of fertilization in the soil and the consequent pollution. But not only: by strengthening the soil structure, the plants are also strengthened, avoiding the consequent depletion of nutrients and the subsequent desertification of the cultivated areas. Organic fertilizer can also be cheaper than chemical fertilizer, especially if you use products that are readily available locally. Nowadays, specialized shops also offer the sale, at affordable prices, of natural fertilizers. If you have time and patience, good natural fertilizers can also be created with the DIY method. This is the case of compost, for example, which is obtained from the decomposition and fermentation of organic waste. Remains of plants, fruit peels and the like can be decomposed in holes dug in the ground or in containers called “composters”. The home composting time is longer than the industrial one, but in the end you will get a good natural soil suitable for growing potted plants.


Disadvantages

Natural fertilizer has disadvantages in the case of large-scale cultivation. Often, for commercial reasons, it is difficult to respect the fertilization times given by the organic fertilizer. This is why organic fertilization is often combined with chemical fertilization. Furthermore, in large-scale plants, the eventual transport of organic fertilizer would be more expensive than the chemical one. The only disadvantage of organic fertilization in the home is represented only by the risk that the fertilizer used is infected with germs and bacteria capable of attacking plants. This risk is avoided by using composted organic fertilizers.


Organic fertilizer: where to buy and costs

Organic fertilizer can be obtained directly at home or in the garden, using vegetable waste and other remains of organic waste. If you have a passion for nature and live near a forest, you may also be able to find peat, which, as already mentioned, fully falls within the classification of organic fertilizer. In case of difficulty in finding, organic fertilizers can be bought in agricultural and gardening shops and in e-commerce. The prices of these products are now quite affordable. The price of organic fertilizers ranges from six euros for half-liter packs to twelve euros for one-liter packs. Five-liter organic fertilizers can cost as much as sixty euros. These products are exclusively based on natural or organic substances, such as algae and guano. The formulation of organic fertilizers on the market is mainly liquid.


The best fertilizer for olive trees to ensure proper growth and abundant fruit production

L'olive tree it is a very resistant plant, able to live for years without fertilizers and in extreme nutritional conditions. However, to ensure proper growth and abundant fruit production, it is necessary to ensure that the plant is cared for and fed properly.

For this reason the choice of a specific fertilizer for olive trees it is essential: whether it is a potted plant or an underground plant, the nourishment must be selected on the basis of very specific parameters that must take into account, among other things,age of the plant and of chemical-physical characteristics of the soil in which it grows.

The olive fertilizer must be characterized by the presence of a series of nutritional elements which are not always available in the soil in the right percentages.

Therefore, we cannot think of cultivating this plant with generic fertilizers because there is a risk of not obtaining the desired results, that is, a high production of fruit and a balanced and healthy growth of the same.

The nutrients necessary for the growth of the olive tree are mainly three, namely L'nitrogen, the phosphorus is the potassium. They are accompanied by other microelements, among which they cover particular importance the boron is the magnesium. The different nutrients are needed in greater or lesser quantities depending on the life stages of olive trees.

For this reason they usually stand out three types of fertilizer, that is, those that are to be used in the plant, during the growth phase and during the production period. In addition, depending on the seasons and therefore the life cycle of the olive tree, it will be necessary to fertilize the soil in a more or less intense manner, once again taking into account the chemical-physical characteristics of the same.

A special note is needed for those who want to cultivateolive tree in pot, that is, as a decorative plant to keep on the terrace or balcony. In this case, fertilization is essential since the plant has a reduced amount of soil. In this case it is essential to fertilize the plant at the beginning of the summer and in case of repotting.


Domestic fertilizer with manure

If you enjoy the world of gardening or cultivation, you will know for sure that the manure is one of the best natural fertilizers existing. You can find ready-to-use manure but if you have animals like chickens, rabbits or goats or pets you can use their droppings to enrich the soil of your plants, thanks to its high nitrogen content.

Of course, you shouldn't add the droppings directly to the base of the plant, but compost it before using it. In we tell you how to make natural fertilizer.


Stages feeding tomatoes

Organic fertilizers for tomatoes can be used at any stage of their growth. Substances are introduced into the soil before seedlings, used for irrigation and processing of slabs.

Tomatoes require additional feeding in the following stages of development:

  • after landing in a permanent place
  • before flowering
  • in the formation of the ovary
  • during fruiting.

Between the procedures, 7-10 days should pass to avoid the overgrowth of plants with microelements. The last feeding of tomatoes is carried out two weeks before harvest.


Different types of organic fertilizer for the garden

What is the best organic fertilizer to use? There are a number of organic fertilizers to choose from. There may be all-purpose chemical fertilizers, but this doesn't exist on the organic side of gardening. Different organic fertilizers add different nutrients and ingredients to the soil. The materials you need completely depend on your soil and the plants you are growing in the garden.

Plant-based fertilizers

Plant-based fertilizers decompose faster than other organics, but typically offer a greater amount of soil conditioning than actual nutrients. These materials, such as alfalfa meal or compost, help add drainage and moisture retention to poor soils. Other plant fertilizers include:

  • Cottonseed meal
  • Molasses
  • Cover crops of legumes
  • Cover crops for green fertilizers
  • Kelp seaweed
  • Compost tea

Animal-based fertilizers

Animal-based fertilizers, such as manure, bone meal, or blood meal, add a lot of nitrogen to the soil. It is great for broadleaf plants and strong growth in the first few weeks of gardening. Additional animal-based fertilizers for the garden include:

  • Fish emulsion
  • milk
  • Urea (urine)
  • Manure tea

Mineral based fertilizers

Mineral-based fertilizers can add nutrients to the soil, as well as raise or lower the pH level when needed for healthy plant growth. Some of these types of organic fertilizer are:

  • Football
  • Epsom salt (magnesium and sulfur)


2. Fertilization

Not all plants and vegetables, however, have the same nutritional needs: some want fairly consistent fertilizations, while others are satisfied with a minimal amount. Some need mainly natural nitrogen for plants, while others consume very little, but on the other hand they absorb a lot of phosphorus.

Specifically, aromatic plants must be fertilized with extreme caution: an excess of organic fertilizer limits their development and reduces their scent. Generally it may be sufficient to administer about a quarter of the doses indicated for other pot plants.
