HE LIQUIDATION OF THE POTATO WITH NEW ZEOPROFIT HELLAS FERTILIZERS.
Potato production and quality are factors directly linked to the sufficiency of nutrients and therefore lubrication plays an important role. It is therefore of the utmost importance that the lubrication programs are optimized. From all the nutrients, Potassium is absorbed by growing potatoes in larger quantities. Potassium is the determinant of production and quality It has a positive contribution to the production, transport, conversion and storage of carbohydrates through the activation of plant enzyme mechanisms. It regulates the osmotic state of the cells and the distribution of water. Cultures that are adequately equipped with Potassium use less water per unit weight of the plant biomass and can do much more easily in times of drought. Contributes to better exploitation of nitrogen. Ensures economic harvests.
Potassium:
It has absolute relevance to the most important metabolic mechanisms and therefore plays a major role in the quality of tubers. Increases the resistance of the tuber to color changes (internal tanning, black staining, browning discoloration, tan after cooking). Potassium, the nutritional element of the quality Increases the citric acid and vitamin C content. Optimizes the resistance of the tubers during collection and storage ensuring their full maturity. Increases starch content. Achieves the best nitrogen exploitation.
When potassium is deficient:
Normal growth of the plant is prevented. Older leaves become open green and later yellow mostly peripheral. Then the discoloration becomes peripheral drying and the symptom is transferred to the newer leaves. Foliage and shoots are withering before maturation, stopping the assimilation process and diminishing production. Quality is negatively affected because the sensitivity to external and internal damage is particularly high (enzymatic transitions, external blackouts). The influence of potassium on the content of reducing sugars K2O / ha without potassium decreases production and quality Sufficient potato content in leaves Before flowering 4.5 - 7.0% K Flowering principle 4.0 - 6.4% K End Flowering 3.7 - 6.1% K Tubing 3.5 - 5.7% K
Potassium for high production:
For these reasons: High productions need, at least, sufficient land resources of potassium that should remain high with fertilization. Deficiencies of potassium in the soil lead to severe production reductions The soil must be adequately provided in the early stages of cultivation and in any case before the start of vegetation. In addition to soil analysis, nutrient levels should also be examined with foliar diagnostics. Depending on the direction of production (potato chips, starch or consumption), different fertilization programs should be followed..
Quality requirements vary:
The characteristics required vary according to the direction of cultivation. Potatoes intended for chips require a moderate starch content. On the contrary, those grown for starch production require a high content of this. Potassium triglyceride inhibits the production and transport of starch in the tuber. The percentage of starch per tuber in fields with low potassium may be increased by conservative applications of potassium fertilizers.
Concentrate content of starch is also influenced by the form of potassium, i.e., sulphate or chloride. High levels of chlorine in the plant prevent production and transport of starch to the tuber. Chlorine has the aforementioned negative effect even if it is applied much earlier (4-12 weeks before planting), because chlorine does not wash off into deeper layers. Conversely, the use of potassium sulphate promotes the production of starch and leads to a much higher crop
... for fresh consumption:
The ideal state of potatoes for fresh consumption is the excellent appearance (without external damage and illness), easy peeling, excellent cooking appearance and, of course, very good taste. A disadvantage for potato is the deteriorated appearance due to the discoloration, either inside the tuber (tan) or peel, or during cooking (brown or black potatoes). For this reason, the lubrication programs must achieve, in addition to high production, the required quality by consumers.
Magnesium is important ...
Potatoes are particularly susceptible to Magnesium . For this reason it is necessary to include the element in a balanced lubrication treatment.
Magnesium plays a major role in the function of photosynthesis, protein synthesis and the activation of different enzymes.
Magnesium deficiency prevents protein synthesis and is often accompanied by too much accumulation of nitrates in the tubers. Growth is prevented and the result is low production and quality.
Soils with high pH have generally low availability of Magnesium and need additional Magnesium Lubrication to meet potato needs of this item. Magnesium sulfate that is water-soluble in all soil PH is the ideal source of Magnesium at high soil acidity.
