The garden can be fertilized with natural organic fertilizer which is better than the chemical ones which alter the biological balance and impoverish the soil in the long run.

Organic fertilizer, i.e. animal manure, compost, wood ash and even dried animal blood, leaves the soil soft and drained, guaranteeing all the nutrients necessary for the soil.

How and when to fertilize

Depending on the type of plant, it will be decided when and how to fertilize since the nutritional needs are also different based on the duration of the production process.

During growth, plants must be fertilized constantly in the ways and quantities specified for each different species to avoid the onset of disease and desiccation. The ideal period is in late autumn or early winter: the soil, after being plowed, will have to be cleaned of any roots of old crops and then it will have to be fully fertilized to create a fertile bottom up to 40 cm deep and then the whole crop will be raked. surface. The fertilizer of this first process must contain high levels of nitrogen, whether organic or granular fertilizer with slow release over time are used. Then in spring, before sowing, the soil must be tilled and enriched with additional fertilizer. During the flowering period it will then be ideal to use manure to enrich the soil with phosphorus and therefore to increase the growth of vegetables in quality and quantity.

Types of fertilizers

There are various types of fertilizers also based on the release times of the mineral salts in the soil: the quick-acting fertilizers release the nutrients in a very short time (a few hours or a few days), while the slow-release ones need a few weeks up to a few months to have chemical efficacy.

Fertilizers with fast mobility can also be dissolved in water to irrigate the soil, while poorly mobile fertilizers must be put in contact with the soil near the roots.

Then there are mineral fertilizers, chemical ones and organic mixed ones suitable for intensive agricultural crops and for specific crops; granular, powder or liquid ones.

For organic fertilization, on the other hand, natural fertilizers such as animal, vegetable and mixed fertilizers are used, which have zero impact on the environment and health.

The most used fertilizer is still manure from animal excrements, mixed with dry grass and straw fermented all together, the most common is the bovine one, very suitable for fertilizing sandy soils; and to follow the compost which is a set of vegetables and fruit no longer usable, branches, cut grass and peat; both of these two types of fertilizer perform a nutritional action on the soil in a rather short time, also stimulating the growth of vegetables. A good fertilization made with manure is 3 or 4 quintals of mature manure for every 100 square meters of horticultural area.

However, to avoid problems with the neighborhood (due to unpleasant smells) a worthy substitute for the main fertilizers is pelleted manure, perfect for any type of cultivation but above all for vegetable gardens and for crops in pots. Its main feature is to rebalance the PH of the soil, making it less acidic.

Fortunately, pesticides are used less and less and some plants have been introduced by farmers to be placed close to vegetables, which host insects or small animals that eat unwanted parasites, thus avoiding pollution.

To restore the balance of substances in the soil, the method of crop rotation is increasingly used in order to allow time for the soil and its nutrients and chemicals to regenerate.

The organic garden

To create and maintain an organic garden it may take a little more effort and consistency but the advantage is to always have fresh vegetables, without pesticides and therefore benefits for the body and total respect for the environment, with a considerable money savings.

Contact with nature is also re-established as the natural cycles of the earth are followed for cultivation.

The area to be cultivated must be sheltered from bad weather in winter and very sunny in spring and summer.

On the other hand, to eliminate parasites without the use of pesticides, it is sufficient to use simple rules offered by nature: weeds should not be pulled out because they help to maintain the ecological balance; the same goes for the nettle, which keeps away many harmful parasites and insects and instead it is good to let ladybugs, dragonflies, bees and earthworms proliferate, which will eliminate any unwanted parasites.
