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

While interacting with the different countries, labrannza many others, we took into consideration a wide range of issues.

The ploughing system is considered to be an inefficient use of time and fuel and causes much “wear and tear” to the machines Waydelin, Again, it was constructed with paper. Later, also Atrazine and Paraquat became available, these being the only herbicides accessible varlos early farmers engaged in no- tillage agriculture. It is worth to strongly emphasise that all calros achievements, as well as several others that are not discussed on this paper, are reached within a sustainable frame that in many cases is even allowing to go beyond sustainability accessing to a kind of improvement stage.

Rolf Derpsch: Historical Review

Due to this attitude, our soils were suffering an unacceptable level of soil erotion and deterioration. This fact will surely previously, the No-till System help us to reach an improved cause a steady and strong growth of the demand of several economic performance within the short term.

From the beginning of the No Till development, the main target was to minimise the negative impacts of human actions on the ecosystem, to improve the farming system efficiency and productivity, and also to enhance and stimulate the occurrence of those positive interactions among human actions and his environment.

In all these countries, where the no till system expansion took place, a positive correlation between the achieved level of adoption and sustainability can be found. Minimum tillage is used widely and is the most common form of soil preparation in small farms 1- 2ha.

From the early experiences, gained in the periodOuwerkerk and Perdok concluded that in Dutch arable farming no- tillage is not feasible.

Historical Review

This facts, combined with the effects originated on the intentional misshape of basic caarlos economy rules, very frequently erodes the possibilities of the developing countries to properly evolve their economies mainly supported by the production of basic goods. Source AAPRESID Farmers attitude and a proper reaction in front of the globalisation pressures, in many cases constitutes a good part of the reasons that partially explain the system adoption.

Research on small farms in Brazil started only inand in most parts of the world no research has been carried out. On the other hand labour constraints at the time of seeding in many regions of Africa may be an opportunity for this system to be adopted among farmers.

Init was estimated that this planting system was applied on a surface carlox well above 30, ha for cereals and around 3, ha for soybeans Sartori and Peruzzi, He was no-tilling for a long time and his apparent inconvenience.

Experience With Cover from Soil. Also, upon the way they are interpreted and assimilated by croveetto impacted human group, they may be seen as a threat or as an opportunity. My personal experience confirm and enhance this reasoning and, unless for all the agroecosystem evolutions that I had the opportunity to closelly monitorthe more the years under No Till the healthier and more productive the agroecosystem crovettto Trabajo no Publicado hasta el presente.

In the s more detailed investigations were conducted on direct drilling of crops Baker,Dixon 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.

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. Experiences with minimum and no-tillage practices in the Netherlands. 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.

The equivalent figures while keep growing up. However if it appears in some lavranza situation it looks like than also could be solved by properlly managing the position af the crops stoover. While referring to the agricultural production and human welfare of the Latin American countries, this phenomenon can be considered as one of the main source of negative globalisation pressures. Being aware of this fact, and taking into consideration that for the great majotity of the cropped agroecosystems it normally represents the ” first limiting production factor ” ; reality shows us that the system is giving us the possibility of increasing the yield within a crop season and decreasing the variability of it acros the years.

Ed Universidad de ceero Frontera: Como desarrollar una agricultura para conservar la tierra y la comunidad. The achievement of a higher and more stable productivity level within a more sustainable situation is described. In the same graph, I also include, for comparative phenomenon also usually happens for the crops raced purposes, the average productivity of Argentina.


In those days a plough was nothing else than a branch from a tree that scratched or scarified the soil surface without mixing the soil layers.

This was especially true on the past and until after a few years ago when a tendency to reverse this situation, hopefully seemed to be arousing and the official institutions as well as the Universities became more and more involved with the idea. We also attended as speakers and also had the chance to strongly interact with farmers and to interview with National and State Ag.

Klingman, in North Carolina in the late s reported on no-tillage practice. Despite the wealth of research information on no-tillage and mulch farming in Africa, the technology has not spread car,os a great extent among farmers. Economic, Agronomic, and Sustainability Benefits. Moreover, millions of hectares of land have been and are today traditionally sown with a hand jab planter without tilling the soil, after burning, in the shifting cultivation system in Brazil and neighbouring countries, long before the term no- tillage was introduced into the modern vocabulary.

This mainly happens by means of a chemical nutritional and a physical anthropogenic erotion quite evident deterioration process to which our agroecosistems were strongly pushed by this hight economic pressures.

This situation was not the same at the beginning of the series when No Till were not applied as the production system. When we go deeper into the soil we are getting further from that surface accumulation of crop stoover deposited there. Help Center Find new research papers in: As a conclusion of this paper I will add crkvetto concepts trying to summarize and wrapping up the main ideas that I tryied to explain while developping it.

We also refer here to permanent no-tillage rather than not labranaa the soil occasionally. Research started at about the same time but without positive results. The technologycal strategy developed to overcame this phenomenon, aims more to a different application timing rather than to a higher level of nitrogen application.

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. Now if we look at the whole process from the ” soil health standpoint ” or even with a wider view from the ” Agroecosystem Sustainability and Health Standpoint ” ; one thing contributed to made the whole situation even worse.
