Evaluating the Effect of Tillage on Carbon Sequestration Using the m.nim.m.Detectable Difference Concept

Pedosphere 2008年第4期18卷 421-430页

Three long-term.field trials in hum.d regions of Canada and the USA were used to evaluate the influence of soil depth and sam.le num.ers on soil organic carbon (SOC) sequestration in no-tillage (NT) and m.ldboard plow (m.) corn (Zea m.ys L.) and soybean (Glycine m.x.L.) production system.. The first trial was conducted on a m.ryhill silt loam.(Typic Hapludalf) at Elora, Ontario, Canada, the second on a Brookston clay loam.(Typic Argiaquoll) at Woodslee, Ontario, Canada, and the third on a Thorp silt loam.(Argiaquic Argialboll) at Urbana, Illinois, USA. No-tillage led to significantly higher SOC concentrations in the top 5 cm.com.ared to m. at all 3 sites. However, NT resulted in significantly lower SOC in sub-surface soils as com.ared to m. at Woodslee (10-20 cm. P = 0.01) and Urbana (20-30 cm. P m.re SOC storage than m. at the Elora site (3.3 m. C ha-1) and at the Woodslee site (6.2 m. C ha-1) on an equivalent m.ss basis (1350 m. ha-1 soil equivalent m.ss). Sim.larly, NT had greater SOC storage than m. at the Urbana site (2.7 m. C ha-1) on an equivalent m.ss basis of 675 m. ha-1 soil. However, these differences disappeared when the entire plow layer was evaluated for both the Woodslee and Urbana sites as a result of the higher SOC concentrations in m. than in NT at depth. Using the m.nim.m.detectable difference technique, we observed that up to 1500 soil sam.le per tillage treatm.nt com.arison will have to be collected and analyzed for the Elora and Woodslee sites and over 40 soil sam.les per tillage treatm.nt com.arison for the Urbana to statistically separate significant differences in the SOC contents of sub-plow depth soils. Therefore, it is im.racticable, and at the least prohibitively ex.ensive, to detect tillage-induced differences in soil C beyond the plow layer in various soils.

A survey on distributed com.ressed sensing： theory and applications

The com.ressed sensing （CS） theory m.kes sam.le rate relate to signal structure and content. CS sam.les and com.resses the signal with far below Nyquist sam.ling frequency sim.ltaneously. However, CS only considers the intra-signal correlations, without taking the correlations of the m.lti-signals into account. Distributed com.ressed sensing （DCS） is an ex.ension of CS that takes advantage of both the inter- and intra-signal correlations, which is wildly used as a powerful m.thod for the m.lti-signals sensing and com.ression in m.ny fields. In this paper, the characteristics and related works of DCS are reviewed. The fram.work of DCS is introduced. As DCS＇s m.in portions, sparse representation, m.asurem.nt m.trix.selection, and joint reconstruction are classified and sum.arized. The applications of DCS are also categorized and discussed. Finally, the conclusion rem.rks and the further research works are provided.
