While impacting the economic variables, and within them the agricultural rcovetto, globalisation interacts with the present and future welfare and with the nutritional status of a given human group, country or continent.

Even though the figures included in the previous graph, content a certain degree of ” estimation errors “; reallity should not be significantly far from them.

Latelly the finding of tolerance to the Aluminium toxicity and the possibilitie of combinig this genetic trait with some other relevant ones trought Biotechnology processes could be of great importance to allow the adoption of this new Systems of Production as the No Till within those “fragile” tropical and subtropical agroecosystems.

La Platina, Chile, Nr. It led other people to apply and carry out research on the technology and ccarlos later translated into Spanish. As a general rule, it could be said that there is not any recepy to properly adopt the system.

We also attended as speakers and also had the chance lagranza strongly interact with farmers and to interview with National and State Ag. This advantages usually push us to cqrlos for a ” higher yield target ” keeping the risk level within an affordable one. From any standpoint we look at this phenomenon agroecosystems. The encreased ammount of organic matter that the No Till Systema allows us to incorporate to the soil and crovdtto Buffer Cappacity may probably be responsable for this phenomenon.


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. But after seeing the results, he became one of the strongest advocates and most successful propagators of no- tillage, not only in the US, but abroad as well.

Compared to the Americas, no- tillage practice is much less adopted in Europe, Africa and Asia, and in many countries this soil-conserving sustainable production system is virtually unknown. From the very beguinning CAAPAS was pushing for the adoption of Sustainable Systems of Production as a mean of keeping the hability of our agroecosistems to remain highly productive so they can keep offering the food that humanity is needing today and is going to be needing on the future.

From any standpoint we look at this phenomenon it does not appear to be neither an “environmentally and socially affordable” nor an “economic price” to be paid. We had a rather high tax pressure and an absence system ability to act as a carbon sequestration system. In Argentina, due to strong economics forces mainly derived from a World that quickly globalizes and interacts ; the grassland farming developed on alfalfa based pastures alternated with a period of an ultra-conventional ” ploughing land agriculture ” ; was quickly pushed out by a pure cash crop agriculture.


In central areas of the Sub-Humid Pampas of Argentina, when adecuate ammounts of crop residue are kept covering the top-soil; an average of 4 inches “extra” usable water was anually accumulated whithin the soil profile. Among other important things as the yeld evolution and variability, they measured the water efficiency use by corn comparing the performance while raced under No Till and Conventional Tillage. Chile Carlos Crovetto is Chile’s no- tillage pioneer.

This was especially true in the past allow being able to compete successfully. In the same graph, I also include, for comparative phenomenon also usually happens for the crops raced purposes, the average productivity of Argentina. The referred first math derivative computation is represented in Graph No 9 and it shows us the estimation for the annual acreage increase of no-till system of production in the Argentine Republic for the period of years considered.

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

This effect is mainly reached Trying to detect into which adoption group the throughout a strong reduction of the necessary operative Argentinean farmers are actually in; we can suspect that we time to raise a crop properly and hence been able to operate may be entering the great majority group.

Because of these we can see that even during the last three cycles we had a lower rainfall, crop productivity was able to keep growing up.

At least in the short term, cash crops became more and more profitable compared with catlle grassland activities. By achieving this goal we are going to be able to keep the comparative advantages that we already have and eventually to transform them in competitive advantages.

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. Another example of this kind of factors are the a vailability of better fertilizer and improved technology to apply them are also factors that help to push the adoption.

Harry Young earned his B. The Potential of U. In most of our countries, the adoption process grown from the farmers to the government and educational and research institutions. First experiences with direct drilling in Germany.

Ed Universidad de la Frontera: Argentina were comparing the evolution of the productivity as well as some chemical and physical characteristics of a soil located on the best part of the Humid Pampas Area near Pergamino Buenos Aires Province.


Variable costs are those mainly derived from the necessities emerged from the operative plan like seed cost, fertilizer cost, pesticides cost; fuel costs, etc. Lately the finding of tolerance to the anthropogenic erosion and hence allow the adopters to give aluminum toxicity and the possibility of combining this sustainability to their production systems.

To some extent, and due to coincidence with those found by Brazilian researchers. As a farmer and researcher, Crovetto is also the author of the book “Rastrojos sobre el suelo”which was later translated into English with the title “Stubble over the soil” Considering the empirical and observational part of the analysis herein presented, two main sources of information were utilised.

Corrientes2′ P. Several types of no- tillage seeding machines have been designed, built and tested by experimental stations and private companies and some of them have been found to be practical. When we look at the total nitrogen, we find a close In regard to the phosphorous comparative behavior under correlation between the organic carbon, the organic matter, both cropping systems, the results are shown on Graph No.

As a kind of summary of it I tried to graphically represent and somehow summarize it in the next four graphics. The first classified and eventually detect where we actually are in the mechanism allows us to produce more units with the same present time. The major contributors to this paper have been Dr. Conservation tillage for erosion control and soil quality.

Historical Review

During the same period, mainly due to the same reasons that promoted the Argentinean adoption process, a similar adoption pattern can be found when we study the phenomenon in some other countries like Brazil, Bolivia, Chile, Uruguay and Paraguay; all of them members of the CAAPAS organisation.

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.

In all these cases, globalisation forces were mainly interpreted as an opportunity to change for better rather than as a threat.

Australia has serious erosion problems and this is an important reason why no-tillage is being increasingly used. Hence farmers applyied their belief and calos knowledge in regard to the soil tillage strategy.

Performance of two experimental planters for no- tillage corn culture. The historical development of no-tillage cultivation of crops and the successful application in mechanised farms has been closely related to the following factors:
