“…3a). Various papers have addressed the combined effects of tillage and residue management (Benoit and Lindstrom, 1987;Zachmann et al, 1987;McFarland et al, 1990;Thorburn, 1992;Dao, 1993;Logsdon et al, 1993;Karlen et al, 1994;Lal et al, 1994;Rawitz et al, 1994;Singh et al, 1994;Linden, 1994, 1998;Sembiring et al, 1995;Peterson et al, 1996;Sharratt, 1996;Unger et al, 1997;Baumhardt and Jones, 2002), and we highlight some important studies below.…”

“…After fall paratilling in 2002, bulk density values for the ST system were at least 15% less than bulk density values for ST or CT systems that had not been paratilled. Subsequently, disrupting compacted or consolidated horizons/zones via paratilling reduces bulk density and cone index (Bicki and Guo, 1991; Pierce and Burpee, 1995; Truman et al, 2003, 2005), increases infiltration, and decreases runoff (Sojka et al, 1993; Rawitz et al, 1994; Schwab et al, 2002; Truman et al, 2003, 2005).…”

Variable Rainfall Intensity and Tillage Effects on Runoff, Sediment, and Carbon Losses from a Loamy Sand under Simulated Rainfall

et al. 2007

The low-carbon, intensively cropped Coastal Plain soils of Georgia are susceptible to runoff, soil loss, and drought. Reduced tillage systems offer the best management tool for sustained row crop production. Understanding runoff, sediment, and chemical losses from conventional and reduced tillage systems is expected to improve if the effect of a variable rainfall intensity storm was quantified. Our objective was to quantify and compare effects of a constant (Ic) intensity pattern and a more realistic, observed, variable (Iv) rainfall intensity pattern on runoff (R), sediment (E), and carbon losses (C) from a Tifton loamy sand cropped to conventional-till (CT) and strip-till (ST) cotton (Gossypium hirsutum L.). Four treatments were evaluated: CT-Ic, CT-Iv, ST-Ic, and ST-Iv, each replicated three times. Field plots (n=12), each 2 by 3 m, were established on each treatment. Each 6-m2 field plot received simulated rainfall at a constant (57 mm h(-1)) or variable rainfall intensity pattern for 70 min (12-run ave.=1402 mL; CV=3%). The Iv pattern represented the most frequent occurring intensity pattern for spring storms in the region. Compared with CT, ST decreased R by 2.5-fold, E by 3.5-fold, and C by 7-fold. Maximum runoff values for Iv events were 1.6-fold higher than those for Ic events and occurred 38 min earlier. Values for Etot and Ctot for Iv events were 19-36% and 1.5-fold higher than corresponding values for Ic events. Values for Emax and Cmax for Iv events were 3-fold and 4-fold higher than corresponding values for Ic events. Carbon enrichment ratios (CER) were or=1.0 for CT plots (except for first 20 min). Maximum CER for CT-Ic, CT-Iv, ST-Ic, and ST-Iv were 2.0, 2.2, 1.0, and 1.2, respectively. Transport of sediment, carbon, and agrichemicals would be better understood if variable rainfall intensity patterns derived from natural rainfall were used in rainfall simulations to evaluate their fate and transport from CT and ST systems.

“…Within the crop field, the conservation of crop genetic diversity by promoting differentiated cultural patterns has shown to be useful not only for pollination but also for pest and disease management [29]. The contribution of agricultural land to the AES of soil formation can be performed through the following processes: a) soil weathering by crops' rooting systems and rhizosphere microflora [30][31][32], b) soil fragmentation/aggregation by the combined effects of tillage, incorporation of residues and intense wetting-drying cycles due to irrigation especially during summer [33][34][35].…”

Ecosystems provide a range of services, commonly called Ecosystem Services (ESs), which are of fundamental importance to human well-being, health, livelihoods, and survival. One of the largest and most productive ecosystems is agricultural land. Agro-Ecosystems provide a range of services directly linked to the market (e.g. food and raw materials production) but also many others of high ecological value, which have an indirect economical contribution in the GDP (non-market ESs). These non-market services are not usually taken into account in the development of agricultural management strategies while their contribution is reduced due to non-sustainable agricultural practices. The aim of the study is to assess the potential economic contribution of the non-market services at national, regional, and provincial level in Italy and to propose a simplified index-based method for setting priorities at different scales of administration units for the implementation of sustainable agricultural practices (SAPs). The results of the study showed that the potential non-market value of agro-ecosystem services (AESs) in Italy can reach ~46.2 billion USD$2007. This estimate shows that non-market AESs can play an important role in the national GDP if SAPs are followed. Finally, a priority ranking scheme for the implementation of SAPs was proposed at regional and provincial level which can be a valuable decision support tool for promoting sustainable agriculture policies.
