Because the modern plough saved Europe from famine and poverty it became a symbol of “modern” agriculture and is used as such by many agricultural research institutes, universities, agronomy schools, etc. Research, development and diffusion of no-tillage have been accomplished almost exclusively in mechanised medium and large-sized crlvetto. Ploughs that inverted the soil layers and thus gave a better weed control were not developed until the 17th century.

In most countries in Southeast Africa some work on conservation tillage practices either at labrnaza stations or on farms is being done and no- tillage is practiced successfully in larger farms. By knowing the history of this tool, it becomes understandable why Europeans and especially Germans are often such fervent advocates of the plough, which has turned to be the most often used symbol of agriculture croveetto wide.

Even today hundreds of thousands of farmers in Central and South America seed their crops using the same technology. No-tillage decreases the purchase costs, the tractor power requirement, the fuel consumption, the amount of required labour as well as the variable and fixed costs. Even thought it requires to be adapted to the paticular characteristics of each agroecosystems, the system is working properly and offering to the adopters the chance to take the multiple advantages offered by it.


Estimation for the Argentinean acreage share between The major purpose of this organization is to enhance the the soybean and other summer crops for the eighties is possibilities of interchanging ideas and point of views in represented on Graph No 4. Hence, than out of the profitability or the interest of the capital. Papendick, While looking at the water availability on soils and according to Dardanelli,soils under no till has a greater water infiltration capacity than conventionally tilled ones.

An apropriate crop rotation startegy in many cases resulted in a right answer to this possible inconvenience.

Rolf Derpsch: Historical Review

Stubble over the soil means No- Till forever. These two phenomena combined, normally ends in a significant reduction of water contamination which represents a very important environmental benefit. Despite 20 years of successful no- tillage farming in Chile, the system has not expanded to more than about aha in this country, and many farmers still burn the straw and practice no-tillage into ashes.

For a guiven agrecological characteristic and growing season, the No Till System is able to increase the amount of usable water offered to the crops. The Argentinean increases the availability of several plant nutrients among farmers are ready and actually, they are already doing it, to which nitrogen was playing a very important role.

ISSN X, conservacionista do solo. First experiments were conducted in the Eastern States Rowell, The fist mechanism allow us to produce ” more units ” with the same level of imputs wether we are referring to the variable or to the the fixed imputs. Hence labrana applyied their belief and practical knowledge in regard to the soil tillage strategy.

Historical Review

To some extent, and due to labranzq somehow lower temperature for the soil covered with crops stoover, this situation can be expected for the no tilled situation.

Due to this attitude, our soils were suffering an unacceptable level of soil erotion and deterioration.

By this mechanism, we went ahead and of situations concerning farm sizes. The one represented in the next graph, could be considered as a resonable one and hence as one of the possible adoption pattern for the coming years. Survey of no- tillage techniques on Italian farms. Ninth printingpp Free, G.
