Preparation of ground for crop

By preparation of soil for crops it is the extremely important to destroy all weeds. It is necessary to clean vegetation and all stones. The best way will get rid of weeds - earth cultivation twice. Site preparation increases sprouts survival, reducing growth of weeds. The used technics for soil preparation depends on type of soil, an inclination, a condition of the field, existing natural vegetation, and cost.

Having cleared a place under a site, it is necessary to plough it, having processed its ­ cultivator or to dig over manually, deleting large stones. Breakdown of lumps facilitates ­ the subsequent alignment, loosens ­ and improves soil structure­. If the soil clay and heavy, ploughing up can create a compact layer under ­ a soil surface ­ that will lead ­ to drainage deterioration­.

Soil preparation is often carried out manually, mechanically or with use of herbicides, the so-called chemical. Mechanical preparation of a field is carried out with use of the heavy equipment to clear the earth of undesirable vegetation.

It can be as ploughing up or clearing of the earth from undesirable plants. The purposes of mechanical preparation consist in supporting soil on a site, avoiding adjournment of a deposit and to support a site drainage. At chemical processing of soil some kinds of herbicides can be used to eliminate weeds or undesirable plants.

However there are risks at use of herbicides. Always use appropriate herbicide for work and follow instructions. It is not necessary to apply herbicides near to water sources. It is impossible to use splashing herbicides in windy weather with a view of prevention of its hit on other site of the earth.

Fertile the soil containing in 100 of 4% and more humus, 4 mg of mineral nitrogen and more than on 10 mg of mobile forms of phosphorus and potassium is considered. Degree of security of soils if they contain less than 1 % humus, less than 3 mg is very low. Ð2Î5, 4 mg Ê2Î and 2 mg of nitrogen for 100 of soil. Introduced mineral fertilizers should be balanced on structure; as the more in soil contains nitrogen, the should be phosphorus and potassium more, differently they will appear inaccessible to plants.

Quality of preparation of soil vital for grain crops and their subsequent productivity. Preparation should begin in the autumn. The field should be fallow and made ready for the winter, before frosts. Crops are made between February and April. To sow it is possible manually at small volumes of crops, in case of the big sizes to apply mechanical methods of crops.
