The most important factor<\/strong>s in cultivation of grain crops that contribute to increasing productivity include the following ones:<\/p>\n Cereal spiked crops respond effectively to the application of microfertilizers. In the formation of a low level of grain yield (2-3 t\/ha)<\/strong>, most soils are affected by a low supply of macronutrients. Despite the introduction of high rates of fertilizers, the lack of one nutrient can lead to a decrease in yield (Justus von Liebig’s law)<\/strong>. Sometimes lack of several tens of grams of one of micronutrients inhibits assimilation of other nutrients and stops formation of the crop.<\/p>\n Each of the stages of plant development is characterized by the corresponding requirements for mineral nutrition. The main critical periods in the development of grain crops, when they are most demanding for mineral nutrition, are as follows:<\/p>\n Macronutrients such as nitrogen, phosphorus, potassium and mesoelements such as sulfur and magnesium are of particular importance in the formation of high yields of grain crops .<\/p>\n Macronutrients<\/u><\/em><\/strong><\/p>\n Nitrogen (N) <\/em><\/strong>is the main element for the formation of amino acids and proteins. Necessary for the growth of vegetative mass. Participates in the processes of plant metabolism.<\/p>\n Phosphorus (P)<\/strong> <\/em>is involved in energy metabolism. Promotes root growth, formation of generative organs as well as the formation of seeds. Accelerates ripening.<\/p>\n Potassium (K) <\/em><\/strong>is an enzyme activator as well as a heat resistance factor. Participates in the accumulation of sugars, protein synthesis. Together with sulfur (S), it affects disease resistance.<\/p>\n Wonder offers to consider the following fertilizers for foliar nutrition which cover a number of aspects in comprehensive manner:<\/p>\n Mesoelements<\/strong><\/p>\n Sulfur (S) <\/strong><\/em>is an important element of enzymes. Participates in protein synthesis. Lack of sulfur leads to non-assimilation of nitrogen. Signs of sulfur deficiency in cereals are “whitening” of young leaves.<\/p>\n Magnesium ( Mg)<\/strong> <\/em>is the main element of chlorophyll. Accelerates metabolic processes, promotes absorption of phosphorus, potassium and many other elements. The deficiency can be easily identified as “marble” chlorosis, spreading from the edges of the leaf blade to the middle of old leaves. Due to lack of chlorophyll, growth and development of plants is inhibited.<\/p>\n Wonder suggests considering a fertilizer for foliar nutrition:<\/p>\n Microelements<\/u><\/strong><\/p>\n The most important microelements for grain crops are manganese, molybdenum, copper, zinc, boron<\/em><\/strong>. They are introduced into soil together with mineral fertilizers, as well as during foliar feeding and pre-sowing treatment of seeds with products containing trace elements. Wonder suggests considering the following fertilizers for foliar nutrition:<\/p>\n\n
