На основі аналізу факторів зовнішнього середовища та виробничої діяльності людини показано шляхи формування та класифікації агрогенних (агроземних) ґрунтів України.

На основе анализа факторов внешней среды и производственной деятельности человека показаны пути формирования и классификации агрогенных (агроземных) почв Украины.

As well as I known that arable soils present the large group of soils that formed of natural practically in all natural and climatic zones. Processes of transformation of arable soils, their transformation straight or mediated related to productive activity of man. They show up in the correction of natural process of formation of soil, that results in a delay or acceleration of intensity of development of processes of formation of soils, gradual forming of new arable soils that does not have analogues in the system of zonal soils. A formation of arable soils is begun with elimination of horizon of thick felt and mattae in chornozems, bedding and mattae in sod-podzolic and other forest soils, that results in a change water, temperature, gas, power modes of new soils. Throwing open, till of soil at growing of agricultural plants is stipulates mechanical interfusion of the ground mass (trencher ploughing a to 60-65 cm) of overhead horizons and causes violation of natural structure of profile. The structural reorganization of the ground mass : chemical, water physical, physical and chemical, biological indexes of soils actually results in the change of natural process of formation of soils on formation under the action of ploughing, under the action of that the new profile of soils is formed. An agricultural formation of soils forms the new type of soils (agrochornozems, agrosod-podzolic, agro brown soils) that form family of agrozems.
