“…The amendment T5 significantly increased SOM accumulation in soil. This is consistent with the view that plant materials can be an important input for increasing soil quality in rice production systems (Lee et al 2010). Thus, the application of blended amendments with leaves as plant materials to rainfed condition fields is the key in promoting physical attributes of soil quality in agricultural systems without intensifying methane emission in comparison to sole application of inorganic fertiliser NPK, though the treatments enhanced the yield but were not effective in bringing statically difference in yield among the treatments.…”

Introduction: Rice is the main food crop of the world, and the cultivation of rice crop during the monsoon season is hard due to the rain-induced waterlogging. Apart from this, farmers in north-eastern regions of India often implement improper crop management leading to poor yields. Thus, the development of suitable management practices under improved varieties of rice become essential for increasing rice productivity, improving soil quality status and reducing methane emission. Methods: The aim of the study was to investigate the variation in soil properties, crop growth and methane emission under the application of an inorganic fertiliser as well as its mixtures with both inorganic and plant materials. In such an attempt, a field-based experiment was conducted with the rice variety Chandrama during 2015 in slightly acidic soil having sandy loam texture. Five amendments, i.e. NPK and NPK, blended separately with magnesium sulphate, fresh neem (Azadirechta indica) leaves, used tea (Camellia sinensis var. assamica) leaves, and fresh karanj (Pongamia glabra) leaves were used for the study with four replications each. Results: Application of NPK separately with the leaves of neem, tea and karanj separately at the onset of monsoon season markedly affected the soil porosity and the water-holding capacity of the soil. However, in comparison with sole NPK fertilisation, a significance increase in soil organic matter accumulation (2.48 ± 0.10%) was seen only for karanjblended NPK while magnesium sulphate-blended NPK showed the lowest methane emission (0.30 ± 0.01 mg/m

BACKGROUND: Agricultural inputs (fertilizer and organic inputs) and water conditions can influence CH 4 and CO 2 emission from agricultural soils. This study was conducted to investigate the effects of agricultural inputs (fertilizer and organic inputs) under changing water regime on CH 4 and CO 2 emission from a soil in a laboratory incubation experiment. METHODS AND RESULTS: Four treatments were laid out: control without input and three type of agricultural inputs ((NH 4 ) 2 SO 4 , AS; pig manure compost, PMC; hairy vetch, HV). Fertilizer and organic inputs were mixed with 25 g of soil at 2.75 mg N/25 g soil (equivalent to 110 kg N/ha) in a bottle with septum, and incubated for 60 days. During the first 30-days incubation, the soil was waterlogged (1 cm of water depth) by adding distilled water weekly, and on 30 days of incubation, excess water was discarded then incubated up to 60 days without addition of water. Based on the redox potential, water regime could be classified into wetting (1 to 30 days), transition (31 to 40 days), and drying periods (41 to 60 days). Across the entire period, CH 4 and CO 2 flux ranged from 0 to 13.8 mg CH 4 /m/day and from 0.4∼1.9 g CO 2 /m/day, and both were relatively higher in the early wetting period and the

“…Green manuring is a good management practice in agricultural production, because it can improve soil fertility and quality (Kautz et al, 2004;Astier et al, 2006;Stark et al, 2007;Zhang and Fang, 2007;Lee et al, 2010;Zavattaro et al, 2012), and also, supply N, a primary limiting nutrient for crops (Drinkwater et al, 1998;Pypersa et al, 2005;Elfstrand et al, 2007;Xavier et al, 2013).

A 9-year field micro-plot experiment was conducted to investigate the use efficiency, residual effect, and fate of 15 N-labelled ryegrass green manure in soil-crop system, so as to offer useful information for reasonable application of green manures on meadow burozem. Results showed that high application rate (600g per plot) of 15 N-labelled ryegrass green manure resulted in reduction of percent recovery (PR) 15 N plant and PR 15N soil by 25.0% and 12.8%, respectively, and elevation of percent loss (PL) 15 N by 31.2%, as compared with low application rate. The 15 N utilization and loss could be divided into three phases, i.e., high uptake and fast loss in the first and second growth seasons, low uptake and slow loss in the following four growth seasons, and little change in the last three growth seasons. This suggested that the green manure N had a long residual effect but its loss was faster at early phase, and thus, rational application of green manure was of considerable importance to reduce its N loss while improve its N use efficiency.
