Among all the grains rye is the least demanding to the level of fertility of soil and climatic conditions. This culture has a relatively high resistance to lodging, well absorbs nutrients and requires less fertilizers than other grains.
The most important period in the nutrition supply system of rye – the time of formation of the first sprouts before the winter, and theperiod of recovery of growth and development in the spring. In the autumn rye requires intensive supply of phosphorus and potassium – these elements stimulate the development of a strong root system, formation of a healthy sprouts, contribute to the accumulation of a sufficient amount of sugars essential for normal wintering.
Fertilization of rye using nitrogen is performed in on a phased basis and depends on the type of soil and precursors that grew on it. For marginal and sod-podzolic soils and lands with low humus content is recommended the introduction of 30kg/ha of nitrogen in the pre-cultivation period. The scond introduction of nitrogen should be performed in the spring, during the plant vegetation after winter, the third – during the stem-extention stage.
The most important period of the of rye nutrition is tillering phase and stem-extention stage. At this stage occurs the most nutrient absorption by the plant, and the most intensive growth, completion of the formation of strong stems and spikes with all the organs.
Rye is extremely demanding to the supply of useful compounds and tmicroelements. For the soils a with light granulometric composition and poor content content of mobile micronutrient compounds is recommended the introduction of boric and copper fertilizers. Zinc is used on all types of chalk soil and at high content of phosphorus.
