THE KEYLINE SYSTEM AND ITS STORY The Keyline system has changed only slightly from my father, P.A, Yeomans’ original books on Keyline. The main change started in the late s with our work on developing a ripper with almost zero disturbance of soil layer profiles. The modern subsoiler was born and highly accelerated Keyline soil Continue reading 8. Yeomans . There are now many resources and programs available to farmers who wish to transition and move forward with no-tillage farming. Cons of no-tillage farming. Special Machinery is Required; No-tillage farming may require special machinery such as a “no-till drill” to drill through crop residue. Such equipment can cost more than $,[sc:1]. Integrated crop-livestock zero tillage systems allow for the sustainable production of high-yielding pasture without further deforestation; in this system, grazing livestock convert both pastures and crop residues into cash. The ability of pasture to build up the fertility and biological activity of the topsoil is well known. BRAZIL: New Forest Code Could Hinder Climate Goals. For landholdings located in the Cerrado tropical savanna region within what is known as the “Amazônia Legal” (which covers nine of Brazil’s 26 states), 35 percent of forested land must be preserved, while 20 percent must be set aside as legal reserves in the rest of the country.

The analysis as to why the research system had been slow to respond to the needs of tropical Zero Tillage - outlined earlier in Box 3 - was presented to the workshop. Further support for ZT promotion was generated by collaboration with ABEAS 2 and inby the University of Brasilia in the first graduate level correspondence course in Zero.

Zero tillage development in tropical Brazil: the story of a successful NGO activity Author: John N Landers ; Food and Agriculture Organization of the United Nations. The technological evolution and the expansion of Zero Tillage (ZT) in Brazil has been farmer-led. Its growth has been phenomenal, as shown in Figure 1.
It will be noted from the graph that the tropical Cerrado region lagged behind the initial development in South Brazil. Zero Tillage is the main element among several that make up what FAO terms Conservation Agriculture (CA).
Although CA uses some specific practices, and may also use external inputs, it is in essence an agricultural concept that conserves and enhances soil fertility, improves the availability of soil moisture, and increases the soil's biological resources.

In this Case Study, John Landers, a No-Tillage expert working in the Cerrado region in Brazil, explains and discusses the human dimension of the introduction of the No-Tillage system in a tropical part of Brazil.
The Environment and Zero-Tillage. The English edition of this book was inspired and principally funded by the Food and Agriculture Organisation of the United Nations (FAO).
The diversity of the chapter authors implies a certain amount of repetition of basic principles. Another very interesting development in Brazil is the creation of Integrated Crop Livestock Zero Tillage -ICLZT . Millions of hectares of nutrientdepleted, degraded pasture lands were marginally productive and the costs of renovation by incorporation of.
J.T. Sims, P.A. Vadas, in Encyclopedia of Soils in the Environment, Conservation Tillage, Contour Cultivation, and Deep Plowing. Conservation tillage, such as stubble mulch tillage, minimum tillage, reduced tillage, and no-tillage, leaves at least 30% of the soil surface covered by plant residue after planting to reduce erosion and surface runoff.
Introduction. Phosphorus (P) is an essential fertilizer element to maintain or increase the productivity of cropped ecosystems (Condron and Newman,Johnston et al., ).However, recent and predicted future increases in P fertilizer costs, linked to increasing global P demand and declining reserves of mineable phosphate rock (PR) (Cordell et al., Cited by: The accumulation of soil organic matter and therefore soil carbon is, however, restricted to the upper 10 cm of the soil.
By comparison with ploughing, no car- bon beneﬁ t or even carbon deﬁ cits have been found at soil depths below 20 cm. No-till makes little or no con- tribution to carbon sequestration in Size: 2MB. Called direct drilling, no-tillage or zero tillage (ZT), the technique is in part praised for fixing carbon in the soil, thereby reducing the amount of carbon dioxide — a greenhouse gas — released into the air.
It also prevents soil erosion and therefore demands less irrigation.

Because of cost reductions and soil erosion control, no-tillage is being rapidly adopted by farmers in the Americas, particularly in the humid and sub-humid tropics. Compared to conventional tillage (tillage operations resulting in <30% cover of plant residue remaining on the surface), no-tillage combined with crop rotation involving cover crops increases soil Cited by: The transformation of agriculture in Brazil through development and adoption of zero tillage conservation agriculture.

Intensification of rainfed agriculture in the Ethiopian highlands has resulted in soil degradation and hardpan formation, which has reduced rooting depth, decreased deep percolation, and increased direct runoff and sediment transport.

Two studies performed in the tropical central savanna region of Brazil (Centurion et al.,Corazza et al., ) showed that while soil C stocks under ZT were higher than under CT in the surface 0–20 or 0–30 cm depth intervals, when sampling was extended to cm depth these differences disappeared due to lower C content in the 30 Cited by: AfDB launches pilot programme to cultivate the savannah in eight African countries Oct The savannahs of Africa cover a mind-boggling million hectares, of which million hectares are cultivable, the President of the African Development Bank, Akinwumi Adesina, has.
In the s the largest expansion of no-tillage in Brazil (Figure 2) occurred in the Cerrados (savannas of North Central Brazil with only one growing season per year), due to the extensive work of APDC (No- till Association of the Cerrados), which organised the fifth and sixth national no- till conference in Goiania and Brasilia in and.
No-till farming (also known as zero tillage or direct drilling) is an agricultural technique for growing crops or pasture without disturbing the soil through -till farming decreases the amount of soil erosion tillage causes in certain soils, especially in sandy and dry soils on sloping terrain.
Other possible benefits include an increase in the amount of water that infiltrates into. Saturnino HM, Landers JN () The Environment and Zero Tillage; APDC-FAO, Brasilia, Brazil UDC /, CDD Baig MN, Gamache PM () The Economic, Agronomic and Environmental Impact of No-Till on the Canadian Prairies.

You asked me about my opinion on the critical paper on Conservation Agriculture (CA) written by Giller et al. and to be published in ‘Field Crops Research’.
The no-tillage development in Brazil is a proof of this. If today there are Million ha (80% of the cropping area) of no-till in the State of Paraná and 25 Million ha in Brazil. Nowadays, in a context of climate change, economical uncertainties and social pressure to mitigate agriculture externalities, farmers have to adopt new cropping systems to achieve a sustainable and cost-effective grain production.
Conservation agriculture consists of a range of cropping systems based on a combination of three main principles: (1) soil tillage Cited by: Furthermore, the adoption of no-till farming (zero tillage) has the advantage over conventional tillage being the increased sequestration of carbon in the soil (57 g C m −2 year −1) (West and Post, ).
In conservation tillage, some (>30%) of the crop residue is left on the land. CQESTR simulates the effect of management practices on soil organic carbon (SOC) stocks.
