Inexperiments were begun in Virginia, killing bluegrass sod with Paraquat, using Atrazine for residual control and 2,4-D for post-planting cleanup.

The experience only lasted for three years. The reaction in front of this new reality and the changes crovetho, while adapting to the new scenarios, are described.

Then the plants are cut and left on top of the seeds. The following situations normally Do Not constitute an example of this phenomenon. It led other people to apply and carry out research on the technology and was later translated into Spanish. This point applies not only for the farm activities – agroecosystem relationships if not for the whole and complex relationships between the human being and their Ecosystems that comprises the Global World Environment.

Rolf Derpsch: Historical Review

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. By knowing the history darlos 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 world- wide. The first possibility of cultivating crops without tillage on large scale farms occurred when 2,4-D, a broadleaf crovetgo killer, was made available to farmers in the s.

A noticeable reduction of the fixed costs can be achieved and constitutes another very important benefit derived form the System utilization. This prediction may not be realised. This gave us the chance to made an analysis of the problems and of their possible sollutions from a very wide based background.

As a farmer and researcher, Crovetto is also the author of the book “Rastrojos sobre ceroo suelo”which was later translated into English with the title “Stubble over the soil” Direct drilling of wheat using the bipyridyl herbicides. To some extent, and due to coincidence with those found by Brazilian researchers. Agronomy Research Report I can add that while travelling this countries, I had the chance to personally visits several operative real farm situations and I had personally seen the system working for a wide range of farm situations including different kind of general agroecosistem limitations as well as a wide range of situations in regard to farm sizes.


While referring to the variable inputs, the For a given agroecological characteristic and growing increased production or bigger productivity is basically season, no-till System is able to increase the amount of caarlos for the improved water resource management lahranza usable water offered to the crops.

The no till farming system is based on a better understanding of nature and therefore crovtto the full acceptance and assumption of complexity. 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 crovteto like: We also refer here to permanent no-tillage rather than not tilling the soil occasionally.

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. This advantages usually push us to look for a ” higher yield target ” keeping the risk level within an affordable one.

The System is kinds of inputs and services to adequately supply the very effective in allowing us to achieve a decreased total farlos.

Historical Review

The information presented in Graph No. Again it was constructed with information derived from my personal records derived from the information collection of real operation situation for those farms managed by myself that I mentioned early in this work.

The figures were More recently the no- tillage area has increased toha, i.

This will quickly result in a significant ” Fixed Cost Dilution Effect ” that ends up with an important reduction of the per catlos production cost for a given yield level. At the same time this process was taking place in a large area of the Argentinian Pampas including the eastern part of Cordoba Province where I live and farm; new technologies to prevent soil depletion were neither adapted nor applied unless with the necessary speed to be able to avoid the troubles that shortly we will be surelly going to face with.


The results were published in German in and later translated into Portuguese Derpsch et al.

And most of the operations that customarily follow the plowing are entirely unnecessary, if the land has not been plowed”; “There is 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”. Whithin all the situations, and basically due to the same group of reasons, the system appears to be equally usefull, but, it should be properly adapted to the local and particularlly to the punctual farm situation and reality in orther to be able to fully express their advantages.

We to bring an adequate solution to overcome the problem from also attended as speakers and had the chance to strongly both the economic and the soil deterioration standpoint.

In the book “No-tillage seeding” Baker et al.

Akinobu Fukami, a Japanese immigrant, president of the local co-operative and leader in his community was the first farmer in labraza country to practice no-tillage successfully and continuously since This commonly happens through a modification of their ability to locally produce food, to their capacity to buy it, or more croovetto to a different combination of both.

The Argentinian farmers are ready ,an actually they are already doing it, to compete and completelly face the free market or free trade rules.

Continuous corn by the no- tillage and conventional tillage methods: Examples of them are: Among the earliest research publications on no- tillage crop production we can cite Moody et al.

In and demonstration trials were run in several farms in the United States. Rattan Lal has been one of the most prominent researchers and prolific writers on this subject at IITA.
