“…The difference between wheat±fallow and wheat±forage±fallow was noticeable in the 0±25 mm depth, but was not statistically signi®cant. In the 0±50 mm depth of a silt loam soil in New Zealand, Hornes et al (1992) found increased levels of the nutrients P and exchangeable K under the NT cropping system than either minimum or full tillage. Hussain et al (1999), however, found lower K level at 0±50 mm depth under NT compared to CT in an Illinois soil.…”

Soil chemical quality changes and implications for fertilizer management after 11 years of no‐tillage wheat production systems in semiarid Morocco

A long-term experiment comparing no-till with conventional tillage systems across ®ve rotations was evaluated 11 years after initiation. The objectives of the present paper are (1) to report differences in soil chemical properties (namely soil organic matter, total nitrogen, phosphorus, potassium and pH) that have resulted by converting from conventional to no-till under contrasting cropping systems and (2) to draw tentative conclusions and recommendations on fertility status and fertilizer use and management. Soil in the no-till system had increased surface soil organic C levels relative to conventional tillage regardless of rotation. In addition, depending on the rotation, the N and P content of the soil improved with no-till compared with conventional tillage. In other words, no-till has helped to retain soil organic matter (SOM), conserved more N, and resulted in increased extractable P and exchangeable K concentrations in the upper root-zone. Hence, wheat produced in a no-till system may receive more nutrients from decomposition of SOM and acidi®cation of the seed zone. It is possible that lesser amounts of fertilizer nutrients will be needed because of the greater ef®ciency of nutrient cycling in no-till systems relative to conventional systems.

“…Although there was a trend for higher bulk density in the top 20 cm under NT as compared to CT in 2004, the maximum difference between bulk density values within a depth was only 0.14 g cm À3 . Bulk density has been shown to increase (Bruce et al, 1990;Horne et al, 1992;Grant and Lanfond, 1993;Franzluebbers et al, 1995;Dam et al, 2005) within the near-surface soil when reduced tillage or NT practices are adopted. Due to the relationship of bulk density to key processes such as infiltration, gas exchange, and root penetration it has been used as an indicator of soil quality (Doran and Parkin, 1994;Logsdon et al, 1999;Logsdon and Karlen, 2004) and therefore, should be further monitored to determine longer-term effects of NT practices.…”

“…Portions of Manawatu fine sandy loam and Waitarere sand were incubated at field capacity at ambient temperature with four rates (0, 2.5, 5.0 or 10.0 t/ha) of individual biochars. The amounts of biochar incorporated were calculated on the 200 mm ploughing depth commonly used in the district (Aslam et al 1999;Horne et al 1992;Sparling et al 1992). After 21 days, to allow equilibration and mitigation of the liming effect of biochars (Laird 2008), 250 g samples of each soilÁbiochar mix and a control of soil only were spread thinly and evenly on moist Anchor regular weight seed germination paper (ISTA 2009).…”

Biochar made from biosolids, corn stover, eucalyptus, fresh pine or willow pyrolysed at 5508C and incorporated into Manawatu fine sandy loam or Waitarere sand at rates from 0 to 10 t/ha did not significantly affect the germination or early growth (root and coleoptile length, and dry weight) of maize seeds. There were no interactions between type or rate of biochar with soil type. The results suggest that biochar incorporation prior to a maize crop should be investigated as a method of increasing stable soil carbon with the potential for mitigating carbon emissions.
