| Summary: | Romania has a surface of abt. 24 mil ha, and is almost entirely covered with soils. Over 9 millions hectars belong to thegroup of arable soils, cultivated with different field crops and permanently submitted to agricultural machineinterventions. This led to the oxidation of organic matter and of the heteropolycondensed humus due to the lack oftechnical and scientific instruments to stabilize the soils. In the moment when soils in the Southern, Eastern andWestern part of Romania were fallowed, these owned up to 15 % humus, either in a condensed form (huminic acids),either as humus-C, i.e. biomass residua in transformation.By the taking in culture and the soil tillage within the conventional system practiced still in our days, the analysis ofliterature and simulation calculations made by us showed that beginning 1930 until nowadays, over 70% of theagricultural soil humus was lost and abt 29 billions tons of CO2 and other dangerous gases were cast in the air.Recuperation of CO2 from air can be done only by „greening” all the surfaces and reintroducing CO2 in soil as humus.This can be done the speediest possible in a rate of maximum 0,1 % humus /year. There is no a viable solution for this,able to solve quickly the absorbtion.
