“…In general, comparison of the Hendrigan Plot rotations and Classical Plot rotations show the utility of perennial legume forages in off-setting fertilizer N inputs 37,38,39 . The long-term average yields of barley under-seeded to forage on the Classical Plots (NPKS and manure treatments) is around 3220 kg ha -1 , comparable to the CG and 8-year rotation barley yields from the Hendrigan Plots.…”

SummaryThe Breton Plots were established by the Department of Soils at the University of Alberta in 1929. Within the Breton Plots research site, numerous long-term plot experiments have been conducted over the years. This paper summarizes results from the Breton Classical Plots (est. 1930), the Breton Hendrigan Plots (est. 1980), the Breton Tillage Straw Nitrogen plots (est. 1979) and the Breton Nitrogen Immobilization Plots (est. 1982). The experiments were established to find suitable cropping rotations and fertilizer management strategies appropriate for the Gray Wooded soils developed on glacial till in the Breton area of Alberta. Long-term results from the plots show that production challenges on these soils can be addressed with proper nutrient (fertilizer, manure) and residue management and the incorporation of perennial legume forage crops into annual crop rotations.

“…The Breton plots (8.5 m x 31.6 m) are east-'d'est oriented, with less than 0.5Va slope. These plots involved 6 rotation series (A-F), each receiving 11 ferlilizer treatments (plots 1-11) (Wani et al 1994). A subset of rotations, WF and wheat-oat-barley-hay-hay (CH), each unfertllized, with applied manure and N-P-K-S fertilizer, was selected for this study.…”

The effects of management practices on erosion and crop productivity for different agro-ecosystems in Canada are largely unknown. A study was conducted to examine the effects of management on soil loss and wheat yield in long-term research plots, established in western Canada. Soil erosion was measured using the 137Cs technique. Under conventional tillage, topsoil was lost at a rate of 2–37 t ha−1 yr−1. Equivalent loss in topsoil thickness ranged between 0.02 and 0.28 cm yr−1. Soil losses were highest in 2–yr wheat–fallow crop rotations. Continuous wheat, 5–yr cereal–hay rotations, and plots amended with manure reduced soil losses and maintained thicker topsoils. At Ellerslie, Alberta, there was no measurable soil loss from a Black Chernozemic cropped to continuous barley under zero tillage. Decrease in annual wheat yield averaged 106 kg ha−1 cm−1 topsoil loss in the Brown Chernozemic and 117 kg ha−1 cm−1 topsoil loss in the Gray Luvisol.

“…The relation between cropping systems and the quantity and quality of soil organic matter has been inferred from studies of chemical and biological soil parameters (Birch and * ICRISAT JA (1638) ** FAX no corresponding author: +9140 241239 Dougall, 1967;Campbell et al, 1991;Wani et al, 1994a). Recently, measurements of microbial biomass (McGill et al, 1986;Wani et al, 1994b), potentially mineralizable N(No) and mineralizable C (Stanford and Smith, 1972;Wani et al, 1994a) have been used to monitor biologically meaningful changes in the quantity and quality of soil organic matter. Some increases in soil organic matter content and N mineralization potential of Gray Luvisols have been attributed to perennial forages and legumes grown in rotations with cereals (Campbell et al, 1991;Poyser et al, 1957;Wani et al, 1994a).…”

A b s t r a c tThe quantity and patterns of net mineralization of soil nitrogen (N) were studied in Vertisols under different cropping systems in the semi-arid tropical areas. Eight cropping systems were selected; three contained pigeonpea (PP), one contained PP and cowpea (COP), and two contained chickpea (CP) as legume component crops, one included sequence cropping with nonlegumes during the rainy and postrainy seasons, and one system was kept fallow (F) during the rainy season and sown to sorghum (S) during the postrainy season. Cropping systems with PP as a component crop increased mineralizable N(No) content two-fold in the soil compared with fallow + sorghum (F+S)-F+S system. The N mineralization rate constant (k) was not significantly affected by previous cropping history of the soil; however, a numerically higher rate constant was observed in the COP/PP intercrop, followed by sequential S+safflower (SF) system as compared to the other soils. Mineral N accumulation curves for six soils were more accurately described by the exponential model than the linear model. The active N fraction (No/Ntot %) varied between 8 and 16% for different systems and a direct relationship was observed between No/Ntot and total N for the soils under diverse cropping systems.
