conditions are unfavorable for fresh pea, dry field pea offers a potential alternative to summer fallowing. Al-Winter wheat (Triticum aestivum L.) is grown in rotation with though dry pea is grown in the Palouse region of Washfresh pea (Pisum sativum L.) in the wetter (Ն450 mm) zones of ington and Idaho, it is seldom grown in northeastern the inland Pacific Northwest, and with summer fallow in the drier (Ͻ450 mm) zones. Typically, this cropping system has been tillage-Oregon. The potential benefits of replacing summer intensive. Summer fallow deleteriously affects soil properties, while fallow with a dry pea crop include increased organic fresh pea markets have decreased for decades. Alternative wheatresidue addition, biological N fixation, and erosion probased cropping systems are needed. The objective of this 6-yr study tection (Beck et al., 1991). Substituting legumes for falwas to evaluate the agronomic viability of a winter wheat-dry pea low would also reduce the downward movement of warotation under four tillage systems. Primary tillage operations for ter in the soil, and thereby decrease nutrient leaching. wheat and pea residue, respectively, were: (i) fall disk and chisel plow Additionally, similar to fresh pea, dry pea would aid in (Fall D-CH); (ii) fall moldboard plow and moldboard plow (Fall the control of weeds and disease associated with wheat MBD-MBD); (iii) spring moldboard plow and moldboard plow monoculture. Even in the wetter zones of the inland (Spring MBD-MBD); and (iv) fall sweep and skew-tread (Fall SWP-Pacific Northwest, dry pea may provide an alternative to SKW). Spring precipitation strongly influenced dry pea yield, but tillage had little to no effect. Pea yield could be predicted well by a fresh pea because of their broader domestic and foreign model combining precipitation distribution with a heat stress index. market (Muelbauer et al., 1983). Wheat yield was more influenced by winter than spring precipitation,The potential for soil water erosion is great in many and was ෂ400 kg ha Ϫ1 less for the Fall SWP-SKW treatment. Wheat parts of the inland Pacific Northwest because of steep protein content was also reduced in the Fall SWP-SKW tillage treatslopes and the predominantly winter precipitation that ment. The probable reason for lower wheat yield is poor weed control.often falls on frozen soils . Despite Dry pea is agronomically viable as a rotation substitute for summer this erosion potential, many farmers continue to use fallow or fresh pea. The apparent yield decline of wheat yield in the intensive tillage to reduce heavy crop residues and to minimum tillage system needs to be evaluated in terms of tillage costs, help control insects, pathogens, and weeds. A common and improved technologies for weed, residue, and N management.

“…Hill et al (1985) observed that soil under conventional tillage had a larger proportion of its pore volume in larger pores (>15-pn radii) than the soil under conservation tillage. Allmaras et al (1982), on the other hand, showed that in the upper 40-cm layer, cultivation produced small pores at the expense oflarge pores.…”

“…Long-term cultivation influences drying time, soil hydraulic properties and water available for plant uptake (Allmaras et al 1982). A silt loam soil under CT released more moisture under low pressure (Johnson et al 1984), and long-term continuous NT practices retained higher soil moisture than CT by improving soil hydraulic properties and pore size distribution .…”

Azooz, R. H. and Arshad, M. A. 2001. Soil water drying and recharge rates as affected by tillage under continuous barley and barley-canola cropping systems in northwestern Canada. Can. J. Soil Sci. 81: [45][46][47][48][49][50][51][52]. In areas of the northwestern Canadian Prairies, barley and canola are grown in a short growing season with high rainfall variability. Excessively dry soil in conventional tillage (CT) in dry periods and excessively wet soil in no-tillage (NT) in wet periods could cause a significant decrease in crop production by influencing the availability of soil water. The effects of CT, NT and NT with a 7.5-cm residuefree strip on the planting rows (NTR) on soil water drying (-dW/dt) and recharge (dW/dt) rates were studied in 1992 and 1993 during wet and dry periods to evaluate the impact of NTR, NT and CT systems on soil moisture condition. The soils, Donnelly silt loam and Donnelly sandy loam (both Gray Luvisol) were selected and soil water content by depth was measured by time domain reflectometry. Water retained at 6 matric potentials from -5 to -160 kPa were observed. In the field study, -dW/dt was significantly greater in CT than in NT in the silt loam for the 0-to 30-cm layer during the first 34 d after planting in 1992. The 0-to 30-cm soil layer in CT and NTR dried faster than in NT during a period immediately following heavy rainfall in the silt loam in 1993. The drying coefficient (-K d ) was significantly greater in CT and NTR than in NT in the silt loam soil in 1993 and in the sandy loam soil in 1992 in the top 30-cm depth. The recharge coefficient (K r ) was significantly greater in NT and NTR than in CT for the silt loam soil. The NTR system increased the -dW/dt by 1.2 × 10 -2 to 12.1 × 10 -2 cm d -1 in 1992 and 1993 in the silt loam soil and by 10.2 × 10 -2 cm d -1 in 1993 in the sandy loam soil as compared with NT. The dW/dt was 8.1 × 10 -2 cm d -1 greater in NTR in 1992 and 1993 in the silt loam soil and was 1.9 × 10 -2 greater in NTR in 1992 than in CT in the sandy loam soil. The laboratory study indicated that NT soils retained more water than the CT soils. The NTR practice maintained better soil moisture conditions for crop growth than CT in dry periods than NT in wet periods. Compared with NT, the NTR avoided prolonged near-saturated soil conditions with increased soil drying rate under extremely wet soil.
