  1. Change tillage practices

    A randomized, paired experiment in 2004 on loamy soil in Essonne, France (Limousin & Tessier, 2007) found that soil organic carbon levels were 11.4% higher in soil under no-tillage than under conventional tillage management. No-tilled soils also contained more potassium (3.5-11% compared to 3-4.5%). No effects on yield were found between conventional and no-tillage management. No-tillage management showed strong pH gradients depending on soil depth, but ploughed soil had an even pH. The experimental field was divided into two 50 x 16 m plots, which were subjected to either conventional or no-tillage treatment. The crops grown were maize Zea mays followed by wheat Triticum aestivum. Maize/wheat plantings received similar fertilizers. Soil samples were taken from three random locations within each tillage treatment. Organic carbon, potassium and soil pH were measured. To measure the density of the soil, five soil samples were taken from five random locations in each tillage treatment.
