The cultivation of potatoes, solanaceae from America, is not complex but needs some small knowledge about soil, irrigation, climate, sowing and diseases. From the soil point of view, the potatoes need a light, drained and very fertile soil. In this regard, it is good to remember that before the tuber is sown, it is convenient to dig and fertilize the soil during the autumn season, so that it is ready to be sown in late winter or early spring. The soil must be dug and plowed to a depth of about 30 centimeters, creating in parallel a furrow which must contain the potatoes used for sowing. Subsequently mature manure is placed, about 1.5 / 2.5 kilograms per square meter. It is convenient to choose an environment not subject to too much heat, but areas in which long winters and short and mild summers develop; thus making the seedlings of potatoes will have available all the water needed to be used alongside irrigation.
To grow potatoes, start with sowing, using some sprouted potatoes from the previous year. This practice is implemented at the end of the winter season until the spring. The tubers can be buried in pots to keep on the terrace or in the open ground. It is necessary to cover them entirely with soil, to sow them in furrows and spaced about 70/80 centimeters, so as to facilitate the collection and the development of the leaf apparatus. After having drilled the holes, buried the sprouted potatoes, it ends with the closing of the same and with a first irrigation, so as to facilitate the sowing. It is good to remember to pay attention to the onset of diseases and pests, to eliminate weeds and to irrigate in such a way as not to move the earth from potatoes sown since they would not lead to a lush harvest.
Regarding the cultivation practices to be implemented during the cultivation of potatoes, it is necessary to be informed about irrigation, fertilization, weeding and what to do during the harvest. It is good to remember that potatoes need a certain amount of water throughout the development cycle; in parallel it is necessary to pay a lot of attention to the water stagnation that can lead to the rot of both the tubers that are developing under the earth and of that used during sowing. For this reason, watering must take place only when the plants require it and when it is noticed that the soil is well dry. Fertilizing is another fundamental point, to be implemented during the sowing of potatoes. At a time when the soil has not been well fertilized during the preparation, it is convenient to sprinkle, during the vegetative season, on the new seedlings of mature fertilizer potatoes. Weeding is another essential action to obtain a flourishing harvest. In other words it is necessary to work the substrate in such a way as to oxygenate the soil, eliminating, in parallel, the weeds.
Potato cultivation: Cultivation on the terrace
The cultivation of potatoes on the terrace is an alternative that is catching on in this last period, for those who do not have available a land in which to grow these tubers. Regarding this practice it is necessary to have available: soil rich in mineral substances, an awl, seed potatoes and bins. Each bin can contain up to five seedlings that must be arranged in a staggered manner, in order to give more space during development. Fertilization must take place on a regular basis as the substances present in the soil are absorbed very quickly. Even watering must be regular, remembering to pay attention to water stagnation. As the seedlings grow, it is necessary to carry out the tamping operation, both to facilitate the formation of new roots and to avoid both the potatoes coming into contact with the sunlight. The practice ends with the harvest of the potatoes: the aerial part is expected to be dry, the potatoes are removed and left to dry in the air for a few hours, so that they do not rot during storage.
