Traditionally, common salt (NaCl) is applied to control broadleaved weeds under shifting cultivation in Nagaland. The aim of the present study was to find out whether such practice is harmful to the soil. For this, an experiment was conducted on upland rice with 12 treatments, viz. control, weedy check and different doses of NaCl from 20 to 200 kg ha-1. Soil samples were collected at several phases of shifting cultivation and analysed for organic carbon, available N, P, K, pH, electrical conductivity (EC), cation exchange capacity, exchangeable sodium percentage and sodium adsorption ratio. Yield and yield attributing characters were measured and economics was computed. The results revealed that soil organic carbon (SOC) increased after harvest, but decreased after one year. In contrast, available N, P and K decreased during the crop growth and post harvest period. Weedy check followed by an application of 100 kg NaCl ha-1 realized the highest gross and net returns. It was observed that NaCl did not exert an undesirable influence on pH, SOC and available NPK; however, EC increased for a short time. The results were confirmed by the verification trial. The yield of rice was highest in 100 kg NaCl ha-1 treatment among the treated plots. Hence, this may be recommended to control weeds under shifting cultivation.Keywords

We studied the variable dynamic response of different soil properties under the exposure of three elevated temperature treatments on six land-use systems. After one month of incubation, the associated changes were measured in terms of soil fertility, carbon, microbial biomass and soil enzymes. Our results confirmed the significant increase (P < 0.05) in soil available nitrogen content (by 1.85–49.32 %) with the subsequent rise in incubation temperature for soils collected from orchards and agriculture land uses. We observed a steady decrease in total organic carbon (TOC) levels with increase in incubation temperature varying between 4.1% and 31.4% (P < 0.05) across different soil types and land-use systems, resulting in a significant rising trend for microbial biomass carbon and labile carbon : TOC ratio up to 3°C elevation from maximum temperature. Among the soil enzymes, dehydrogenase, fluorescein diacetate hydrolase and β-glucosidase activity increased significantly with increase in incubation temperature from the ambient temperature, while acid phosphomonoesterase and arylsulphatase activity decreased. Our current research findings will provide new insights regarding temperature control on soil C dynamics and nutrient availability in terms of modified soil enzyme activity that will be useful to model the dynamics of soil organic matter and associated nutrient availability in acid soils.Keywords
