Effect of Long-Term Organic Cropping Systems on Physico-Chemical Properties of the Soils of Indian Punjab

Organic farming is gaining momentum because of awareness among consumers for quality food. The long term effects organic cropping systems on soil yet not have been studies in details. Therefore the present study effect five viz. Poplar (Populus deltoids) + turmeric (Curcuma longa), sugarcane (Saccharum officinarum Linn )+ bottle gourd (Lagenaria siceraria) - broccoli (Brassica oleracea), basmati rice (Oryza sativa) wheat (Triticum aestivum), fodder and maize (Zea mays) summer moong (Vigna radiate) physico-chemical properties was studied at Bhagat Puran Singh Natural Agriculture Farm Research Centre, Amritsar, Punjab (31.5730 N, 75.0660 E). depth wise samples from these were collected after rabi (2018-19) kharif (2019) seasons. system has significantly higher carbon(SOC), carbon stock(SOCS), aggregate associated carbon(AAC), water stable aggregates (WSA) mean weight diameter(MWD) than other systems. Sugarcane pH while lower electrical conductivity (EC) bulk density (BD) compared to In top (0-7.5 7.5-15 cm depths) SOC, SOCS, AAS, EC, WSA MWD subsurface layers (15-22.5 22.5-30 depth) whereas BD surface soil.
