Fertilizing in Culture - POTATO
POTATO
Higher production per acres and good quality

To achieve high production is very important the fertilizing to be applied throughout the growing period . The development of the roots of the potato system is limited and needs a low temperature , especially in the early stages of cultivation . So too satisfy the need of nutrients to meet under such circumstances , it needs more nutrients. That explains the fact that, so that it has more production of potatoes requires intensive fertilization , even when soil analysis indicates an excess of nutrients . In acid soils with pΗ to ( 5.5 ) where the potato is adapted great it needs adding magnesium , but in very acidic soils with pΗ (4,0-5,5), often appears toxicity of magnesium . Excessive toxicity of soil can be corrected by adding calcium . In similar cases, like in organic soils is not a rare occurrence of boron deficiency and in this case it needs an appropriate fertilization . Manure needs to be moved at high level , producing 3-4 tons of potatoes are as follows :


Needs for nutritients for potato(kg / acres)
NUTRIGEN (Ν)PHOSPHORUS(Ρ2O5)CALIUM (Κ2Ο)MAGNESIUM (MgO)

It is very important influence of nitrogen , which accelerates the development of leaves and result in high production in the early period . In contrast , over- fertilization with nitrogen slows ripening potato , reduces weight and increases the percentage of potato which is not suitable for sale. Phosphorus accelerates ripening and potassium has a beneficial effect on the quality of the product.


Suggestions for fertilization

Most of the nitrogen , along with phosphorus , potassium and magnesium and micronutritient elements should be added to the basic fertilization . Additional nitrogen fertilization should be given part by part , in order to meet the constant needs of the plant. Excellent results of cultivation of potato gives banded fertilizer ammonium sulfur , without causing negative for breeding , disease burners , causing the crystal ammonium sulfur.
