“…This finding reveals that, compared to the control, fall-incorporated radish increased the proportion of flow-conducting, fine soil pores, those with diameters ≤ 0.75 mm (Table 3), at the soil surface. Głąb and Kulig (2008) also found that incorporated radish biomass increased the soil volume occupied by pores with diameters < 0.5 mm in a silt loam soil (Typic Argiustoll or FAO classed Luvic Chernozem).…”

“…Amendments can also reduce bulk density, alter soil pore size distributions, reduce a soil's susceptibility to erosion, and slow the formation of surface seals and crusts, thereby maintaining infiltration rates and thus delaying runoff (Bresson et al, 2001;Edmeades, 2003;Haynes & Naidu, 1998). Organic amendment effects on a soil's water-holding capacity (WHC) may or may not occur (Głąb and Kulig, 2008;MacRae and Mehuys, 1985). Adding organic matter may increase both the field capacity and permanent wilting point, resulting in little or no net change (Haynes & Naidu, 1998).…”

Oilseed radish (Raphanus sativus spp. oleifera) reduces sugarbeet cyst nematode (Heterodera schachtii) populations. Fall-incorporated radish biomass may also increase the yield and quality of subsequently grown sugarbeet (Beta vulgaris L.) by improving soil physical and hydraulic properties. This field study determined radish effects on nearsurface soil aggregate stability, water-stable aggregate size distribution, bulk density, and field-saturated water content, as well as infiltration and hydraulic conductivity measured at water supply potentials of -40, -20, and +0 mm H 2 O. In 2003 and 2004 in Twin Falls, ID, radish were grown in a Portneuf silt loam (Durinodic Xeric Haplocalcid) for about 10 weeks in the fall, then incorporated later that fall by disking, followed by moldboard plowing. In early May of the following year, sugarbeet were planted, irrigated, then harvested for yield and quality. In the spring and fall of each sugarbeet growing season, soil samples were collected from two depths, 0 to 5 and 5 to 50 mm, on which we measured aggregate stability and size distribution by wet sieving. Soil cores were collected from 0 to 34 mm to measure bulk density. Also in spring and fall, we used ponded and tension infiltrometers placed in the row to measure steadystate, unconfined infiltration rates and, from those rates, to Additional key words: Raphanus sativus, cover crop, Beta vulgaris, aggregate stability, infiltration rate, hydraulic conductivity W ater use efficiency is increased by improving soil water relations, such as infiltration or water retention, for crops grown in rotation. Adding oilseed radish (Raphanus sativus spp. oleifera) as a temperate-region, non-legume green manure into crop rotations with barley (Hordeum vulgare L.), wheat (Triticum aestivum L.), potato (Solanum tuberosum L.), and/or sugarbeet (Beta vulgaris L.) may enhance soil water relations.Green manures are crops that, while still green or soon after maturity, are incorporated into soil to improve the soil's physical, chemical, or biological properties and thereby increase the succeeding crop's yield, quality, or both (Cherr et al., 2006). Additions of organic matter, including that from an incorporated green manure, are commonly thought to increase soil organic carbon, aggregate stability, infiltration, and hydraulic conductivity (Martens and Frankenberger, 1992). Amendments can also reduce bulk density, alter soil pore size distributions, reduce a soil's susceptibility to erosion, and slow the formation of surface seals and crusts, thereby maintaining infiltration rates and thus delaying runoff (Bresson et al., 2001;Edmeades, 2003;Haynes & Naidu, 1998). Organic amendment effects on a soil's water-holding capacity (WHC) may or may not occur (Głąb and Kulig, 2008;MacRae and Mehuys, 1985). Adding organic matter may increase both the field capacity and permanent wilting point, resulting in little or no net change (Haynes & Naidu, 1998). Alternatively, such additions may decrease WHC, due to decreases in bulk density and chang...

“…Porosity characteristics differ among tillage systems (Benjamin 1993) and nowadays, study on the soil porosity of different tillage treatment is one of the hotspots in tillage research. Previous researches showed that straw returning could increase the total porosity of soil (Lal et al 1980) while minimal and no tillage would decrease the soil porosity for aeration, but increase the capillary porosity; as a result, it enhances the water capacity of soil along with bad aeration of soil (Wang et al 1994, Glab andKulig 2008). However, Børresen (1999) found that the effects of tillage and straw treatments on the total porosity and porosity size distribution were not significant.…”

A study was conducted on the effect of two single practices, including soil tillage and returning straw to soil, and their interaction on soil porosity of maize-wheat cropping system. Field experiments involved four tillage practices, including conventional tillage (C), zero-tillage (Z), harrow-tillage (H) and subsoil-tillage (S), with straw absent (A) or straw present (P). Total porosity, capillary porosity and non-capillary porosity of soil were investigated. The results showed that the soil total porosity of 0-10 soil layer was mostly affected; conventional tillage can increase the capillary porosity of soil, but the non-capillary porosity of S was the highest. Returning of straw can increase the porosity of soil. Through the analysis of affecting force, it can be concluded that interaction of soil tillage and straw is the most important factor to soil porosity, while the controlling factor to non-capillary porosity was soil tillage treatment.
