Practical experience with reduced tillage farming. In this case and due to the System ability to gather more water into the soil profile, when the drought period showed up we had some “extra very valuables inches of water” down there ready for the crop to use them.

According to my personal experience and from the experiences of some colleagues, both of these phenomena of increased yield and decreased variability are increased when we move to the sub-humid and even more to the semiarid regions where water shortages are more frequent and intense.

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. For a given situation, the recognition and adequate characterisation of the globalisation forces, constitutes the first step to find a proper way to counteract them -minimising their potential negative impacts- an even taking advantage of the situation to change for better.

We can see the adecuatelly summarized and represented trought a noticiable yield variability reduction and an important yield encrease. The University of Oklahoma Press: To some extent, and due to a somehow lower temperature for the soil covered with crops stoover, this situation can be expected for the no tilled situation. In the s M. Most of this policies were somehow not recognizing that after all, what they were doing were to oblige farmers to ” virtually sale their soil and soil fertility ” along with their grains, meat and milk.


Taking into consideration the last 30 to 50 years, I personally feel that we, in Argentina, did not have adecuate govermment policies applied to the agricultural economic activities specially if we look at it from a sustainability standpoint.


Also hand jab planters are imported from Brazil GTZ, By achieving this goal, we are U. Another example of this kind of factors labranzz the a vailability of better fertilizer and improved technology to apply them are also factors that help to push the adoption.

Ministers and other Political, Technical and adequate system of production to stop soil destruction in the Educational Authorities of different CAAPAS’s members shortest possible period, at least, for most of the agro- and non members Countries; among others like: All this should be labrranza within a Frame of Sustentability and even Improvement of the Natural Resources involved on the Process.

Chapter in “Advances in Soil and Water Conservation. This phenomenon is shown on Graph No 5. Lqbranza major contributors to this paper have been Dr.

At this time some pioneer farmers began applying no-tillage while looking for a better way to grow soybeans after wheat in a double cropping system two crops in one year. The new farm laws of andwhich promoted conservation compliance, recognised the vital role of no- tillage as a major means of meeting conservation requirements on highly erodible soils Thomas and Blevins, and contributed to a faster adoption of no- tillage.

However, I consider that they comprise good examples for the explanations of the better soil functioning that allows us to improve the physical and economical enterprise performance in the medium and long term. In our country, we are using no-till system from the very north in the Salta and Misiones provinces, to the southern part in Tierra del Fuego.

At present more than million ha of no- tillage worldwide Cannon Press, Harare, pp Wall, P. Click here to sign up.

We know and are strogly convinced that amog other characteristics for a new system to be applyable it Should be Profitable for the farmer.

Within the medium and long term our main goals are centered in reaching Sustainability in the widest sence than we can attribute to the meaning of this word. During this period of time, a lot of economic resources were drained from the agricultural activities to the rest of the economic sectors. A six- year comparison. While analysing the No Till system in countries other than Argentina, most of the information was either personally collected or obtained from different studies and publications.


Klingman, in North Carolina in the late s reported on no- tillage practice.

Historical Review

Argentina Summary Globalisation and some of the effects derived from it are analysed. In modern agriculture this may be a technical challenge or an economic problem, but formerly this meant hard, long-lasting labour for a large percentage of all the people that ever lived on labranzza.

When we look for an explanation of the Argentinian No Till adoption pattern probably they went ahead and adopt the system instead of waiting for a great deal of solutions for their production problems, to be comming from labanza governements or governements technical or even from the academical institutions. We are primarily farmers and then after that we are trying to play some other roles to advantages.

Rastrojos sobre el suelo. After the Ministry of Agriculture of Paraguay with the assistance of the German Agency for Technical Cooperation, GTZ, initiated a Soil Conservation Project in that labraza on no- tillage development and diffusion, the technology expanded rapidly to aboutha in mainly soybeans. And most of the operations that customarily follow the plowing are entirely unnecessary, if the land carlks not been plowed”; “There labtanza nothing wrong with our soil, except our interference”; “It can be said with considerable truth that the use of the plow has actually destroyed the productiveness of our soils”.

A somehow different way to look at the economic benefits within the short run could be sumarized trought the occurrence or to the action of the two main mechanism related to the enterprise economic growth.

When this facts is properly managed, it allows to achieve an increase of the organic matter soil content which at the bottom line means carbon fixation. Final Remarks Although there were many early attempts to cultivate crops without tillage, modern no- tillage research started in the s and adoption by farmers carloss the early s.
