The scheme of foliar nutrition Potatoes

Peculiarities of feeding potatoes

Potatoes are an important grocery culture and raw material for processing. The size and quality of the yield largely depends on the mineral nutrition conditions during the vegetation period. The culture reacts positively to basic organic fertilizers. To form the crop it requires applying of 90-120 kg per ha of nitrogen, 60-90 kg per ha of phosphorus and 120-150 kg of potassium. Excessive nitrogen causes accumulation of nitrate nitrogen in the cash crop and the darkening of soft part of tuber when cooked. Phosphorus affects the quality of starch kernels, potassium influences the synthesis of the storage matter – starch. Potatoes are susceptible to chlorine in fertilizers which why non-chlorine fertilizers are preferable and potassium chloride should be applied under the main tillage since autumn. The potato plants have positive response to magnesium, zinc, mangan and boron.
