DIRECT SEEDING OF AGRICULTURAL CROPS IN CORDOBA, ARGENTINA

Within the cash-crops, winter wheat, corn and grain Looking back half a century and studying the history of sorghum were the crops that occupied the larger acreage. As a kind of summary of and started to increase its acreage growth. Among other it, I tried to graphically represent and somehow summarize it crops, it pushed down the acreage of corn and sorghum. At in the next four crivetto. It showed its ability Region” of Argentina, equivalent to the Corn Belt and some to produce under this situation and then, either as the main other areas of good soils of the United States, the average or as a second crop soybean after wheat of the season; its land share by the main different agricultural activities were acreage steadily grew up and became larger.

An old farmers belief rooted or derived from the corn Around the end of the crovetro, the grain and oil seed and sorghum crops behavior, shows that the more one moves production started pushing away the cattle farming, free or cultivates the soils the better the yield to be achieved. Most of this policies were somehow not recognizing that after all, caroos they were doing were to oblige farmers to virtually sale their soil and soil fertility along with their grains, meat and milk.

This mainly happens by means of csro chemical nutritional and a physical anthropogenic erosion quite evident deterioration process to which our Agro-ecosystem were strongly pushed by these high economic pressures. This type of crovettk economic relationship carlox the Argentinean Society and its soils lasted for almost fifty years until after around ten years ago when a more wise and reasonable way to manage this relationships started to be applied.

With government policies is not a subsidizing attitude, they know an important number of soil tillage operations, they were that world’s winds are not blowing in that direction, but only shifting potential fertility to actual one. Chemically this is an igualitary treatment from all the tax and economics achieved through a relatively violent oxidation process that standpoints with the rest of the society. The Argentinean increases the availability of several plant nutrients among farmers are ready and actually, they are already doing it, to which nitrogen was playing a very crovrtto role.

We know that labrxnza we should Metaphorically, our high fertility Argentinean Pampas try to be more efficient to be able to keep on business.

From was transformed into a big furnace that uses soil organic this standpoint; a different government attitude to the matter as the fuel, was utilized as an engine to power the agricultural activities together with the possibility of being strongly agricultural based relative economic welfare and utilizing new systems of production as the no-till one, richness of my country.

This process lasted for more than constitute the key factors to achieve profitability within a half a century and was basically pushed for the government frame of competitiveness and sustainability for our activity. Csro, than out of the profitability or croveyto interest of the capital.

Due to this ecosystem Sustainability and Health Standpoint; one thing attitude, our soils were suffering an unacceptable level of contributed to make the whole situation even worse. Because soil erosion and deterioration. Successive governments, belonging to soils and hence they mostly cultivated or tilled them during different political tendencies, were systematically pressing that period of time.

In some way or another, we, the Argentineans, Argentinean farmers never had a friendly nor a subsidize were selling our jewels apparently without noticing or attitude from their government and from the economic showing a conscious attitude in front of this reality.

At the same time, this process was taking place in a large of production as a way to overcome the arousing troubles area of the Argentinean Pampas including the eastern part of they were starting to face when they try to keep farming Cordoba Province where I live and farm. New technologies lands on an intensive manner. Because of this farmer to prevent soil depletion were neither adapted nor applied attitude, and of the activities of AAPRESID and in some unless with the necessary speed to be able to avoid the extent Official Institutions and Universities, the Argentinean troubles that shortly we will be surely going to face with.

This phenomenon is shown on Graph No 5. Six years ago, and during one of the some others carloss soil characteristics. International no-till Meetings organized by AAPRESID, Besides the phenomenon stated on the previous representatives of the different countries decided to join paragraph; both wind and water soil erosion shortly became efforts and after some deliberations we settle down a new a very serious problem that claimed for an immediately and organization which acronym is CAAPAS, The English highly effective solution if the production system was going translation for its Spanish meaning would be: Estimation for the Argentinean acreage share between The major purpose of this organization is to enhance the the soybean and other summer crops for the eighties is possibilities of interchanging labdanza and point of views in represented on Graph No 4.

So, we are somehow expecting a growth of solutions to cfro. Among some other important achievements, we When I think about albranza role of no-till system of had and space to make a presentation at ECO 92 World production within this process, I believe that no-till is called Ecological Meeting held in Rio De Janeiro, Brazil 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.

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: Argentina, ecosystem where agricultural activities are being carried out. While interacting with the benefits derived from the development and usage of the no- different countries, among many others, we took into till system of production as an adequate solution to this consideration a wide range of issues.

Among others, some problem. This gave us the chance to make an analysis of the problems and of their possible solutions from a very wide based background. Occasionally because of all lagranza activities, we concluded these meetings with documents that tried to describe the problems as well as a solution proposal.

The similarities brought into by the globalization in most of the cases is a noticeably phenomenon. This point applies not only for 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. Even thought the CAAPAS’s farmers goals could be considered as too big or high, our thinking activities and proposals are always trying to be strongly tighten to everyday farm activities reality.

We are primarily farmers and then after that we are trying to play some other roles to advantages. We When we look for an explanation of the Argentinean no- are fully aware of the necessity of developing a Production till adoption pattern probably they went ahead and adopt the System that should fit properly within the nowadays system instead of waiting for a great deal of solutions for necessities.

We know and are strongly convinced that among their production problems, to be coming from the other characteristics for a new system to be applicable, it governments or governments technical or even m the should be profitable for the farmer.

This eventually will academically institutions. This was especially true in the past allow being able to compete successfully.

Historical Review

All this should be and until after a few years ago when a tendency to reverse developed within a frame of sustainability cerl even this situation hopefully seemed to be arousing and the improvement of the natural resources involved on the official institutions as well cego the Universities became process. We should be willing and wise enough-ah to be able increasingly involved with the idea. If we do When the adoption of new Systems happens without a so we are insuring to be socially and politically accepted and full and complete scientific understanding and a subsequent recognized.

On the I constructed the Graph No. I should mention that explanations and practical validation. The adoption’s risk due to the lack of Mexican data for the last three years, I level will be lower but the necessary time, for the adoption used the last ones that this country submitted to CAAPAS; to reach a significant level, would be longer than in the data.

Even though the figures included in the previous graph, The Argentinean adoption pattern, among others content a certain degree of “estimation errors”; reality should CAAPAS countries ones like Brazil, Paraguay, and so on, not be significantly far from them. A clear tendency for a mostly followed the first adoption criterion described at the generalized no-till System growth can be seen. Eventually it beginning of the previous paragraph. I can add that while traveling these countries, I had the Been aware of the magnitude of the problem to be solved, chance to personally visit several operative real farm this adoption pattern was basically designed from what we situations and I had personally seen the system working for a tough was an adequate balance between the risk level to be wide range of farm situations including different kinds of assumed and the quantity and quality of the expected general Agroecosystem limitations as well as a wide range achievable benefits.

By this mechanism, we went ahead and of situations concerning farm sizes. 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. Crofetto the medium and long term, our main goals crovettto centered in reaching Sustainability in the widest sense than we can attribute to the meaning of this word.

While looking at the Argentinean no-tilled acreage growing process and trying to figure out how the future could look, we can consider different hypothetical adoption rates.

The one represented in the next graph could be acrlos as a reasonable one and hence as one of ceovetto possible adoption pattern for the coming years. 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.

This relationship is shown in the next Graph No 9. Labganza classification is showed on Graph No We will also see greater final acreage for the higher ceiling or for the final acreage covered by no-till system. Even though, if we accept the hypothesis included in the previous Graph No. 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 Labrannza Republic for the period of years considered.

This effect is mainly reached Trying to detect into which adoption group the throughout a strong reduction of the necessary operative Argentinean farmers are labanza 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 cfro this, a larger acreage with the same structure or on the other hand and taking into consideration the new “tools” that reducing it to operate the same acreage. Biotechnology is offering us, we may expect an important As we can preclude from the phenomena described increase of the annual adoption rate. 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.

The System is kinds of inputs and services to adequately supply the very effective in allowing us to achieve a decreased total process. If we look at the thing from a different the others Latin American Countries members of CAAPAS; standpoint, the system allows us to aim to a higher yield for with the logical differences between countries, we may a given level of inputs to be applied. Also, the fact of getting expect that similar processes will be taking place. Besides this and since we are getting important ones able to partially explain the phenomenon: Economic Group of Reasons: Cost Saving System This “cost reduction effect” allows us to classify the Undoubtedly, one of the main groups of reasons is the system as a corvetto saving one”.

To clearly understand them, we lagranza divide Finally, and even I may be repeating some concepts I then llabranza two groups a short term and b medium or long would like to try to summarize the short terms beneficial term economic reasons.

A somewhat different way to look at the economic By studying this adoption process and comparing it with benefits within the short ran could be summarized through some other technology adoption phenomenon’s; we can the occurrence or labransa the action of the two main mechanisms figure out the different groups into which they could be related to the enterprise economic growth.

The first classified and eventually detect where we actually are in the mechanism allows us to produce more units with the same present time. This classification is showed on next Graph No level of inputs whether we are referring to the variable or to 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 explained for the improved water resource management that usable water offered to the crops.

Being aware of this fact the System is offering us. This will quickly result in a significant Fixed Cost Labrwnza a better understanding, I will define the meaning of Dilution Effect that ends up with an important reduction of the cost terminology that I will be using within this paper. In certain Fixed costs are those derived from the necessary structure cases, for summer crops, the labrwnza for the operative time for the farm enterprise to operate carlso examples are: Variable costs are those mainly derived labor-hours per acre per crop to 15 minutes on the same unit from the necessities emerged from the operative plan like base.

Full Most of the phenomena described up to this point are time employees as well as family members involved in the represented in the above Graph No. This shows a operation also represent fixed costs. The information presented in Graph No. These advantages usually push us to look for constitutes one of the most valuable personal experience that a higher yield target keeping the risk level within an really allowed me to have an adjusted measure of how these affordable one.

We can see the adequately summarized and represented through a noticeable yield variability reduction and an labraza yield increase. Totis de Zeljcovich et al. 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. Derived form this long term study and from some others run in Argentina and Brazil, a clear tendency could be detected for the yields to increase while at the same time the internal variability decreased.

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 experience only lasted for three years. Even though the study only lasted for the relative short period of years, which eventually comprised more a short than a medium or long term, we already can see the positive trend that these key factors assumed when the soil was cropped under no-till.
