By cultivating the land for sowing wheat, we create, above all, conditions for quality sowing and germination, but also for the development of physical, chemical and biological processes in the arable layer.
Five million to help farmers
By processing, we enable the development of the root system, better accumulation of water in the soil, better aeration of the soil and prevent the appearance and spread of weeds, eggs and larvae of pests and plant pathogens. Basic tillage will largely depend on the type of land, pre-crops, depth of tillage under pre-crops, soil condition, but also economic justification.
On lighter soil types processing depth should be up to 25cm, and on heavier 30-35cm.
If the pre-sowing treatment was of high quality and deep, for wheat, processing at a depth of 15 to 25 cm is sufficient, because wheat responds well to the effect of previous deep processing.
If the pre-crop is some stubble or a crop that is harvested by mid-summer, then immediately after removing the crops, it is necessary to plow the plant remains to a depth of 10 to 15 cm, and on that occasion, about fifty kilograms of urea should be dispersed for their better decomposition.
By plowing, plant residues are included in the process of circulating organic matter in the soil, the biological activity of the soil is stimulated and it has a positive effect on the structure and water-air and thermal properties of the soil.

Plowing to full depth should be done in the fall. If the pre-sowing is corn, and the corn is not exported from the plot, then it is necessary to chop the plant remains and plow to the full depth. Plowed soil should not be left in open furrows, in order to preserve moisture in the soil. It is recommended to disperse and plow one third of nitrogen and the entire amount of phosphorus and potassium before basic plowing. Apply the remaining amount of nitrogen fertilizers in top dressing.
By pre-sowing soil preparation, we create a small, loose surface layer that provides favorable conditions for quality sowing, germination and germination of plants. Depending on the condition of the soil and the available mechanization, it can be done with disc harrows, harrows, seed drills or rollers. If the basic tillage is done with quality, and the optimal soil moisture is preserved, then the pre-sowing soil preparation can be done with a harrow or a seed drill.
