Some no-till farmers have had success in reducing use of pesticides and fertilizers on their farms. In the case of fertilizer use reduction, soils under no-till for 10 to 15 years had "rebuilt" themselves to the point where not as much fertilizer supplementation was required to produce a good crop. In the case of pesticide use reduction, less herbicide use was attributed to growing more vigourous and healthy crop plants that could compete better with weeds. A pilot project for pesticide reduction, called "Pesticide Free Production" was conducted in Manitoba for 5 years with very positive results.
