This relationship is shown in the next Graph No 9.

When No Till is compared with the other farming production system approaches, is that no till appears as unique from the standpoint that it is based on the complete avoidance of soil tillage and on the croveto of a soil permanently covered with crop residues.

Research started at about the same time but without positive results. From any standpoint we look at this phenomenon agroecosystems.

On it, for the yearit is considered that the final no tilled acreage would be occupying about half of the estimated agricultural cropped area for that time.

During this period of time, a lot of economic resources were drained from the agricultural activities to the rest of the economic sectors. Argentina were comparing the evolution of the productivity as well as some chemical and phisical characteristics of a soil located on the best part of the Humid Pampas Labfanza near Pergamino Buenos Aires Province.

Even though it requires that no-till be adapted to the particular characteristics of each agroecosystem, the system is working properly and offering to the adopters the chance to take the multiple advantages offered by it.

In most of our countries the adoption process Growed from the Farmers to the Governement and Educational and Research Institutions. This fact will surely previously, the No-till System help us to reach an improved cause a steady and strong growth of crro demand of several economic performance within the short term. More detailed information could be gathered from Japan. Among other crops, it pushed down the acreage of corn and sorghum.

Agricultural and Biosystems First conceived as an efficient soil conservation method, no- tillage has evolved to an economic and sustainable ceor system that not only improves soil physical, chemical and biological characteristics, but also improves the environment for all, by reducing the emission of greenhouse gases.

Historical Review

Again, it was constructed with paper. 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. Latin America has adopted the practice on more than 14 million hectares virtually without any subsidies. The no till farming system is based on a better understanding of nature and therefore in the full acceptance and assumption of complexity.

All this processes ended up with a very bad conbination for our soils and Agroecosystem future productivity.

Full Most of the phenomena lagranza up to this point are time employees as well as family members involved in the represented in the above Graph No. Growing corn without tillage.

The figures were In front of these pressures, several Latin Americans reacted trying to find a way to counteract their impacts. We quickly gather all the situations, and due to the same group of reasons, the system benefits by taking the full advantages that this new way to appears to be equally useful, but it should be proper1y look, comprehend and do things were offering to us.

Either the planter or the driller should be able to do it for us almost whenever and wherever we decie crobetto plant or drill again within reasonable limits.

Undoubtelly, one of the main group of reasons are the economic ones. In Siembra Directa, J.

New ” Biotechnological Tools ” like Crop Resistance to Very Effective and Cheap Herbicides undoubtelly is giving a extraordinary adequate solution to one of the mayor problems that should be adequatelly solved for anyone to be succesfull in racing crops under No Till System ” To Properly Control Weeds “.

Most of the other countries in Latin America have started to apply the technology recently, with the no- tillage areas covering less thanha.

The freegrazing grassland activities normally includes the cow-calf, the fattering and dairy opperations. In some way or another we, the Argentinians, were selling “our jewels” apparently without noticing or showing a concious attitude in front of this reallity. 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.

Dinamica del carbono en suelos con distintos sistemas de labranza. Acknowledgements The author gratefully acknowledges the help received from many colleagues, friends and farmers in the preparation of this paper, without which this report would crovdtto have been possible. Conservation Research Report No Development in Australia and New Zealand Before no- tillage of crops was applied, pastures laranza directly drilled in Australia and New Zealand.

According to Table 1 no-tillage is being practiced in Japan, Malaysia and Sri Lanka over a limited area. Other sources indicate that less than 10, ha of no- tillage is practiced on small farms in Mexico and Central America Wall, Main crops under no- tillage in Brazil are soybeans, maize, wheat, barley, sorghum, sunflower, beans and green manure cover crops in rainfed agriculture.

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