Correction to: Improving soil organic carbon and microbial functionality through different rice straw management approaches in rice–wheat cropping sequence

Organic fertilizers are enriched in plant nutrients which may enhance the soil chemical properties. However, studies on the effect of long term fertilization on soil chemical attributes is yet lacking in Bangladesh. Therefore, an experiment was conducted to assess the changes of soil chemical properties as influenced by long term manuring and nitrogen fertilizer in silt clay loam soil under rice-wheat cropping system. The experimental plot received different organic materials for the last 26 years (1988-2014). Five types of organic materials treatments such as control (no manure), cowdung, compost, green manure and rice straw were applied at the rate of 0, 25, 25, 7.5 and 1.5 t ha-1, respectively in a yearly sequence. Three levels of nitrogen viz. 0, 75 and 100 kg ha-1 for rice and 0, 80 and 120 kg ha-1 for wheat were applied in this study. Long term application of different organic materials positively increased soil organic carbon and total N, P, S and decreased pH and K, Ca and Mg availability. Increase in soil organic carbon was found maximum under green manure and lowest in rice straw applied soil. The green manure contributed to the maximum accumulation of soil nitrogen. N dose of 80 kg ha-1 was found effective in increasing availability of soil nutrients.

A study was conducted at Organic Farming Research Centre of SKUAST -Jammu during 2016 to 2017 to find out the impact of organic manures on soil organic carbon, physical and crop growth parameters Okra-Dhaincha-Broccoli cropping sequence. The Soil Organic Carbon was analyzed by Chromic acid wet digestion method. However, in soil physical properties Bulk density was analyzed by Core method, water holding capacity by Keen Rackzowski Method and Infiltration rate by Double Ring Method. In the experiment, soil organic carbon was found non-significant in experiment. Bulk density was found to be significant in year 2016 and 2017 as very captivating change was observed as compared to control; T8 as the lowest value treatment with value 1.26 g cm-3 was recorded. Water holding capacity was found to be significant in year 2016 and 2017 as very positive change was observed as compared to control as WHC with highest value 43.68% was noted in T8 in 2017. Infiltration rate was also found to be significant in year 2016-17 as very positive change was observed as compared to control. Significant improvement in root volume, root length was observed in Okra and same was noted in size of curd in broccoli as compared to control. The significant impact of organic manures on soil quality parameters will provide a new way to improve the soil health and productivity in a sustainable way.
