LUBRICATING ASPARAGUS WITH ZEOPROFIT HELLAS FERTILIZERS.
Soil Lubrication Based on the soil's chemical composition and taking into account the following, we proceed to lubricating. On acidic soil fertilizer is fertilized with 100 kg organic fertilizer per acre. The lubrication is significantly supplemented by adding 60 kg of magnesium sulphate (10 units per acre).
When improvement in calcium, to supplement the lubrication fosforo kalicho 0-12-12 fertilizer (10 units 10) that sweep the plowing. When there is no organic fertilizer, local incorporation in the planting lines with organic nitrogen may be used. Instead organic fertilizer can also use organic matter of plant origin. We also need to emphasize the effectiveness of boron in asparagus fertilization, which we can offer for cultivation in the amount of 3 kilos per acre of grass. Because boron is used by the plant in a small amount to use it after planting.
Soil preparation
The field is prepared with a deep plowing of 40-60 cm, depending on the soil. Succession of work Organic fertilization or greasy lubrication Possible calcium improvement. Deep winter plowing (with the incorporation of potassium slag).
NITROGEN:
In rare cases we can use large amounts of nitrogen. Experimental data, carried out in France and other asparagus countries, on different soil types, have shown that a dose of nitrogen does not respond to corresponding shoot production. Also, strong doses of nitrogen, given in some cases, do not have a corresponding increase in yields.
PHOSPHORIC ACID:
This element is consumed a little by the asparagus. Its effect is quite defined. It has an effect on the quality of asparagus, on the reduction of fibrin. Also in the development of roots. That is why when planting the rhizomes it is used with dispersion within the lines at a height of 5-10 units per acre. Potassium lubrication should be made between
in between, after planting and in an amount satisfactory. We can use an amount of 18 units per acre.
BORON:
Boron is also an element whose role is not obvious in asparagus. It is supposed to play an effective role in feeding it. Some authors attribute to the lack of boron the drying of the young vegetation. The explanation given to drying, only in the absence of water does not seem to be valid. But boron is an element that is easily bound into the soil, by an excessive presence of calcium or by drought. The known conclusions consider asparagus, as a boron-specific plant (more than 0.5 p.p.m. in the soil). The coefficient 43-55 p.p.m. in the upper part of the plant is considered to be deficient. Normal is between 55-130 p.p.m. Specific boron doses can practically be, on a basis of 3.5kg of northern wood in acre for 3 years.
MAGNESIUM:
Most of the sandy soils are deficient in this element, because it is not kept well. Although the requirements are difficult to determine, Kaufmann recommends 5 units of magnesium per year. Against Franken, German experiments have shown that the growth of asparagus depends on the amount of magnesium in the soil. In addition to its perceptible role, in the chlorophyll system, magnesium enters storage of carbohydrates and sugars. This phase is important in the performance of the asparagus. It is necessary, very often, to enrich the soil with magnesium with offers of sulphate or potassium Magnesium at a rate of 8 units per acre for 3 years.
IRON:
According to KNOTT, the asparagus is considered to be demanding in iron. Its ratio to soil should be greater than 0.5 p.p.m. in this item.
FROZEN Again, according to Knott, the asparagus responds favorably to zinc offers on the ground and on the foliage. A favorable effect is known in the control of asparagus slag with zinc salts (MoncozebeZirame).
SODIUM:
Sodium favors the ionic balance of soil nutrients. Based on experimental data, some authors recommend the use of sodium-based fertilizers (NO3Na).
LUBRICATING SEASON:
The era of supply to the asparagus cultivation of the necessary fertilization plays an important role in the normal growth and production of asparagus plants. There are various views on the supply of fertilization before or after harvesting or 1/2 pre and 1/2 after. From experimental data, however, there are better results when nitrogen and potassium are offered after harvest or 1/2 pre and 1/2 after harvest. The other fertilizers, P205, Mg and boron, can be offered in May-June. Fertilizations should be avoided too late, because they often cause a start of stem growth in the rhizome, undesirable at the end of the stem cycle. Fertilizers in our country must stop in July.
TYPES OF FERTILIZERS:
The type of nitrogen fertilizer, most in use, remains Ammonia Nitrogen. However, the type of Nitrate and especially Sodium Nitrate (NO3Ne) is often the type recommended in terms of satisfactory results that have been achieved in the cultivation of asparagus.
Sodium (Na) may have a beneficial effect, according to some researchers. The type of Calcium Nitrate (NO3) 2 Ca can also be used in acidic soils. In conclusion, prefer nitric and ammoniacal or ammonium sulfate. S04 (NH4) 2 • The type of organic organic nitrogen, type of horn, dried blood, is also used by producers. Its use is more correct, by incorporating it with the other soil fertilizers that are given in asparagus cultivation. The interest lies in the phenomenon of the release of digestible nitrogen and the addition of other valuable elements, which are once incorporated in the fertilizers by their industrial production (barium, magnesium, etc.). The use of nitrogen-bound fertilizer composites may also be of interest. But the development of these compound fertilizers in the soil varies with its origin and fertilizer in relation to the temperature and nature of the soil.
PHOSPHORIC ACID:
The two most used types are superphosphate and slag. Types of superphosphate, used during winter tillage or stratification by incorporation into the soil, can be used either type. Slags are richer in calcium (50% CaO) than superphosphates (20-30% CaO), they also carry magnesium and boron, two elements considered important for asparagus cultivation. The content of slag in tuna, magnesium and boron is limited (20-30 kg of magnesium and 20-70 g of boron). The type of potassium slag has the same benefits as simple slag, but the calcium content is reduced by 20-30% CaO. There is a high dose of P and K. In acidic soil, dross is preferred. The granular state is easy to disperse.
Other phosphate fertilizers can also be used when considered, their composition, their delicacy, serving their fast use.
KALIO AND MAGNESIUM:
For the choice of Potassium Sulphate (804K2) or Chloride (ECG), there is a matter of consistency in the taste properties of asparagus, without this affecting the taste of one or the other. However, it does not seem to be right that the positive kali, gives the asparagus bitter, more accented. Agronomic does not seem to be a difference in energy between these two types. Because some researchers assume, in a favorable activity of Chlorine ion, one could prefer O1K. Patented or double positive Kali and Magnesium (28% K20, 0.8% MgO and 18% sulfur) have the advantage of offering more potassium than Magnesium. It is preferable that magnesium be offered in a simple form. Nitric potassium (NO3R2) is a highly soluble fertilizer with a content (13% N and 45% K2 O). It does not respond to a balanced lubrication of the asparagus. It can be used as a supplement, but its price is great.
