Correct fertilization of barley
Barley is one of the crops that yield a good yield only on highly fertile soils that contain a sufficient amount of nutrients. The plant assimilates most of the useful micro- and macroelements in the most active phase of development – the first 30–35 days. Therefore, it is important to take care of the fertilizer for the barley beforehand.
Fertilization systems for barley
Choosing the right fertilizer will protect your crops from early lodging and ensure a crop of grains with high nutritional value. Let us consider in detail how to fertilize barley and how to choose the optimal feeding doses.
What fertilizers are suitable for barley’s:
Nitrogen is one of the most important macronutrients responsible for the full development of plants. The nitrogen concentration in the soil directly affects the growth and formation of the seeds.
Types of nitrogen fertilizers:
Ammonium nitrate is a mineral fertilizer for soils with a low acidity level. Not used for foliar feeding.
Calcium ammonium nitrate contains calcium, potassium and magnesium. It is used on soils with high acidity.
Urea-ammonia mixture is a long-acting high-nitrogen fertilizer. Indispensable for dry climates.
Phosphorus stimulates the fertilization process of barley, influences the formation and maturation of seeds. Barley’s experiences the greatest need for it during the period of germination and development.
The most popular phosphorus-containing fertilizer for spring barley, obtained from phosphorites treated with sulfuric acid. Helps plants resist fungal diseases and bloom more abundantly, is used to feed barley on the leaf. Superphosphate reveals its potential only in soils with neutral pH.
Potassium regulates water and nitrogen metabolism in barley cells, increasing its resistance to drought and disease. In addition, the enrichment of the soil with potassium accelerates the maturation of grain and has a beneficial effect on the formation of proteins. The largest amount of potassium is consumed by barley in the initial period of growth.
It is used for soil preparation, as well as for foliar and root top dressing during germination, exit into the chimney and heading of barley. It has become widespread due to its low price, simple and safe use. The maximum effective dosage for foliar feeding of barley is 0.4 l of potassium sulfate with trace elements in combination with 5 kg of carbamide per 1 hectare.
