Deep Plowing

Deep plowing (DP) has been investigated as a possible ameliorative procedure for Solonetzic soils, but the long-term effects of DP on soil properties are not known. Soil sampling to determine the long-lasting effects of DP on some soil chemical properties and crop yields was conducted at four sites with Solonetzic soils in east-central Alberta. The soils had been deep plowed 11–29 yr prior to sampling. Compared to adjacent unplowed (check) treatments, DP resulted in significant improvements in soil chemical properties at most of the sites. The sodium adsorption ratio (SAR) of the AB horizon (12- or 15- to 30-cm depth) was lower after DP at all four sites. Extractable and soluble Ca increased in the Ap horizon (0–12 cm) of DP soils, whereas extractable Na decreased in the Ap or AB horizons at three sites. The pH of the Ap horizon increased from acidic to neutral at three sites, while EC of the Ap horizon decreased at two sites. Crop yield increased due to DP at the three sites where yields were measured. The results indicate a long-term amelioration of Solonetzic soils by DP.

Long-term effects of inorganic and corn stalks organic nutrient sources on yield, soil organic carbon(SOC) and the relationship between crop yield and SOC were investigated in Dry-Land Farming Institute of Hebei Academy of Agricultural and Forestry Sciences, Hengshui, Hebei Province, China from 1981 to 2005. Hengshui is a part the North China Plain and the dominant cropping systems are Winter wheat-maize rotations. Recently the use of organic manure with grain crops has almost disappeared. This could reduce soil fertility and crop productivity in the long run. There were sixteen treatments applied to both wheat and maize seasons: Inorganic fertilizers as main plots and corn stalks as subplots and the main plot and subplot all have four levels expressed A and B respectively. So there are sixteen treatments with three replicates were set (A1,A2,A3,A4)*(B1,B2,B3,B4). After more than 20 years crop yield and SOC decreased in treatment of without fertilizers and only applicate corn stalks just sustain it. Combine application of inorganic fertilizers and corn stalks increase SOC and crop yield very strongly. For crop yield the more fertlizers the more increase. But the SOC will decrease as the more inorganiac fertlizer application and increase with the increase of corn stalks.

Abstract Loss of nitrogen from the agricultural production system is of concern in Ontario. The challenge for researchers and farmers is to fulfill crop water requirements while limiting chemical movement with surface and subsurface runoff. The main objective of this study was to evaluate the long-term effects of current N management practices for corn production for two different soil types using the Root Zone Water Quality Model (RZWQM) for southern Ontario conditions. The model simulated the amount of subsurface tile drainage, residual soil nitrate-nitrogen (NO3-N), NO3-N in subsurface drainage water, and crop yield. The validated RZWQM for silt loam and sandy loam soils showed that the relative long-term effectiveness of the most economic rate of nitrogen (MERN) for corn production fluctuates significantly from year-to-year in response to weather patterns. In addition, soil type had a small but significant effect on the MERN. Side-dress application of N on sandy loam resulted in significant reduction in corn yield and NO3-N loss to shallow groundwater. Also, crop rotation from corn-soybean to corn-soybean-soybean resulted in a greater reduction of NO3-N loads in the tile outflow on silt loam soil than on sandy loam soil. Overall, the RZWQM simulated tile drain flow, NO3-N loss, and crop yield with reasonable accuracy. However, more field work is needed to assist with identifying suitable values for a number of coefficients used in the RZWQM's nutrient component for Ontario conditions.
