“…Results for infiltration rate and runoff indicated that land use change on páramos increased runoff flow and sediment losses from natural undisturbed páramos were very low. Ruy et al (2006) studied the effect of corn crop residual on runoff and soil loss in la Tinaja (Mexico-State of Jalisco). Four treatments were analysed: bare soil no till and no plant with 1.5 t ha -1 , direct drilling of corn with 1.5 and 4.5 t ha -1 .…”

Soil erosion is one of the key challenges in soil and water conservation. Vegetation that covers soil and organic and inorganic mulch is very useful for the control of erosion processes. This study examined treatment with wheat residual (as agriculture mulch) on infiltration, time to runoff, runoff coefficient, sediment concentration and soil erosion processes. The study has been conducted for sandy-loam soil taken from summer rangeland (Northern Iran) with simulated rainfall intensities of 50 and 100 mm h-1. The experiment was conducted in slopes of 30% in three replications with two amounts of wheat residual of 50 and 90 %. The results showed that conservation percent of soil erosion for wheat residual 50 and 90% was 61.68 and 73.25%, respectively (in rainfall intensity of 50 mm h-1). Also, the conservation percent of soil erosion for wheat residual of 50 and 90% cover was 70.68 and 90.55, respectively (in rainfall intensity of 100 mm h-1). It was concluded that the conservation treatments could reduce runoff coefficient, sediment concentration and soil erosion and increase the time to runoff and infiltration coefficient. This effect was significant on time for infiltration, sediment concentration and soil erosion variables (R2=0.99), time to runoff and runoff coefficient variables (R2=0.95). The interaction effects of rainfall intensity and soil conservation was significant for sediment concentration and soil erosion variables (R2=0.99).

“…The effect of wheat residual on the change of time to runoff and runoff coefficient with cover of 90% was more effective toward cover of 50%, but this efficient effect was observed in rainfall intensity of 50 mm h -1 . Ruy et al (2006) presented that the runoff coefficient is reduced more with application of high straw mulch. Fig.…”

In this part of the paper, we review the effect of residue cover on soil mineral N, available P and exchangeable K. Although it is expected that changes in soil bulk density may occur under a no-till bare soil compared to a no-till soil with surface crop residues, especially during the first years of the experiment, the use of nutrient concentrations instead of stocks does not essentially affect the final relationships and conclusions that we found on the effects of surface crop residues on soil nutrient availability.…”

Conservation agriculture, which is based on minimum tillage, permanent soil cover and crop rotations, has widely been promoted as a practice to maintain or improve soil quality and enhance crop productivity. To a large extent, the beneficial effects of conservation agriculture are expected to be provided by permanent soil cover with crop residues. Surface crop residues play an important role for crop growth through their benefits on soil-related structural components and processes in the agro-ecosystem, referred to in this study as agro-ecological functions. Through a meta-analysis of the literature, we have studied the relative effects of surface crop residue levels on the performance of a set of agro-ecological functions compared with a no-till bare soil, i.e., without surface residues. The selected agro-ecological functions were soil water evaporation control, soil water infiltration, soil water runoff control, soil loss control, soil nutrient availability, soil organic carbon (SOC) stocks and gains, weed control and soil meso- and macrofauna abundance. The potential effects of crop residue cover were quantified using boundary line models. Our main findings were (1) 8 t ha−1 of residues were needed to decrease soil water evaporation by about 30% compared to no-till bare soil. (2) To achieve the maximum effect on soil water infiltration, water runoff and soil loss control, residue amounts of at least 2 t ha−1 were required. (3) The effect of increasing the amounts of surface crop residues on soil nutrient supply (N, P and K) was relatively low; the boundary line models were not significant. (4) The average annual SOC gain increased with increasing amounts of residues, with a mean of 0.38 t C ha−1 year−1 with 4 to 5 t ha−1 of residues. (5) Weed emergence and biomass can be reduced by 50% compared to a no-till bare soil with residue amounts of 1 t ha−1 or more. (6) There was a weak response in soil meso- and macrofauna abundance to increasing amounts of surface crop residues. The maximum effect corresponded to an increase of 45% compared to a no-till bare soil and was reached from 10 t ha−1 of residues. Our findings suggest that optimal amounts of surface residues in the practice of conservation agriculture will largely depend on the type of constraints to crop production which can be addressed with mulching.

“…In this context, various natural and organic mulches viz. crop residues, leaf litter, woodchips, bark chips, biological geotextiles, gravel and crushed stones (Ruy, 2006;Smets et al, 2008a;Ruiz-Sinoga et al, 2010) have been applied for soil conservation. Mulches have extraordinary potential in soil erosion control (Morgan, 1986) and runoff reduction (Poesen and Lavee, 1991).…”

Abstract. Amendments can control the runoff and soil loss by protecting the soil surface. However, scale effects on runoff and soil loss control have not been considered yet. The present study has been formulated to determine the efficiency of two plot sizes of 6 and 0.25 m 2 covered by 0.5 kg m −2 of straw mulch with regard to changing the time to runoff, runoff coefficient, sediment concentration and soil loss under laboratory conditions. The study used a sandy-loam soil taken from summer rangeland, Alborz Mountains, northern Iran, and was conducted under simulated rainfall intensities of 50 and 90 mm h −1 and in three replicates. The results of the study showed that the straw mulch had a more significant effect on reducing the runoff coefficient, sediment concentration and soil loss on a 0.25 m 2 plot scale. The maximum effectiveness in time to runoff for both the scales was observed at a rainfall intensity of 90 mm h −1 . The maximum increasing and decreasing rates in time to runoff and runoff coefficient were observed at a rainfall intensity of 90 mm h −1 , with 367.92 and 96.71 % for the 0.25 m 2 plot and 110.10 and 15.08 % for the 6 m 2 plot. The maximum reduction in the runoff coefficient was in the 0.25 m 2 plot for the two rainfall intensities of 50 and 90 mm h −1 , with rates of −89.34 and −96.71 %. The maximum change in soil loss at the intensities of both 50 and 90 mm h −1 occurred in the 0.25 m 2 plot, with 100 %, whereas in the 6 m 2 plot, decreasing rates of soil loss for the intensities of both 50 and 90 mm h −1 were 46.74 and 63.24 %, respectively.
