Various physical, chemical and biological soil properties in surface (0-5 cm) and subsurface (5-15 cm) soil were determined in a 4-year field experiment conducted at Punjab Agricultural University Ludhiana, India with sixteen treatments consisted of different combinations of fertilizer N (0, 20 and 25 kg N ha-1), P (0, 60 and 75 kg P2O5 ha-1), FYM (0 and 10 t·ha-1) and wheat (Triticum aestivum L.) residue (WR) (0 and 6 t·ha-1) applied to summer-grown soybean (Glycine max L.) and fertilizer N (0, 120 and 150 kg N ha-1), P (0, 60 and 75 kg P2O5 ha-1), and soybean residue (SR) (0 and 3 t·ha-1) applied to winter-grown wheat crop continuously in both conventional tillage (CT) and conservation agriculture (CA), arranged in a split-split plot %K Soybean %K Conservation Agriculture %K Water Stable Aggregates %K Organic Matter Fractions %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=39533
