Some trends, such as the shift to no-tillage, are making agriculture less oil-intensive, but rising fertilizer use, the spread of farm mechanization, and falling water tables are having the opposite effect. ❋ Unknown (2009)
Gradually, research showed that diversified production and no-tillage growing were better for the health of the land. ❋ Karl Kupers (2010)
Because of such studies, conservation tillage methods (with no-tillage the extreme) have increased by a factor of 3 from just 1989 to 1994. ❋ Unknown (2003)
Other names are stubble mulching, ecofallow, limited/reduced/minimum tillage, no-tillage and direct drill. ❋ Unknown (1992)
Other trials in sandy Alfisols in Senegal have proved the positive effect of superficial soil preparation with the hand hoe as well as deep plowing, in comparison to no-tillage (Nicou, 1972 in: Sanchez, 1976). ❋ Unknown (1991)
Soil fertility is influenced positively by means of no-tillage under mulch cover whereby soil temperature fluctuations are reduced and higher temperatures are avoided. ❋ Unknown (1991)
Where soils tend towards compaction, as in most of Senegal, soil preparation could be more favourable than soil-conserving no-tillage to achieve a better root penetration and thus a higher yield. ❋ Unknown (1991)
A higher moisture availability is achieved by a reduction of evaporation and higher infiltration rates in no-tillage under mulch cover. ❋ Unknown (1991)
After a sort time the bulk density can already be greater than for no-tillage and in the long term it can be higher than the latter (Armon and Lal, 1979 in: Dehn, 1981). ❋ Unknown (1991)
There is an absence of soil preparation exclusively in a few regions where no-tillage is practised as in Senegal. ❋ Unknown (1991)
In South Brazil the knife roller is commonly found, both on motor-mechanized farms which practice no-tillage as well as on smallholdings with draft animals. ❋ Unknown (1991)
The no-tillage method is referred to when no soil preparation has been carried out over several vegetation periods. ❋ Unknown (1991)
In the drier zones of the semihumid/semiarid climate no-tillage or a superficial soil preparation is practised due to the short vegetation period in order to complete the planting as rapidly as possible, as is done in most of Senegal. ❋ Unknown (1991)
Soil preparation is minimized or totally omitted for no-tillage under mulch cover. ❋ Unknown (1991)
However, the farmers here prefer minimal soil tillage with a chisel plow or no-tillage in unprepared soil due to the short vegetation period. ❋ Unknown (1991)
Weed control remains a constraint for no-tillage under wetter tropical conditions. ❋ Unknown (1991)
Measures such as no-tillage farming, improved drainage, drip and sprinkler irrigation and crop yield enhancement can all increase output, many of them at relatively low cost. ❋ Unknown (2010)
When using this product, farmers are more likely to turn to conservation and no-tillage systems that protect valuable top-soil. ❋ Unknown (2010)
