Soil is the largest pool of terrestrial organic carbon in the biosphere and interacts strongly with the atmosphere, climate and land cover. Remote sensing (RS) and geographic information systems (GIS) were used to study the spatio-temporal dynamics of croplands and soil organic carbon density (SOCD) in the Sanjiang Plain, to estimate soil organic carbon (SOC) storage. Results show that cropland...

The present investigation is an account of soil quality parameters and wheat (Triticum aestivum HD-2285) yield as influenced by insitu incorporation of paddy straw and its subsequent inoculation with two cellulolytic and one lignolytic fungi. Such information may prove useful to farmers as it may provide them with an option to use the undesired crop waste as partial replacements for synthetic f...

AIM The effects of N-P-K fertilizers in the form of urea, single super phosphate and muriate of potash on development of free-living stages of Haemonchus contortus were studied. MATERIALS AND METHODS Five parasite free experimental plots of 1 m×1 m area, each of paddy leaves (15-day-old) and an equal number of Cynodon dactylon grass were infested with about 10×104 eggs/ml phosphate buffer sal...

In this paper, we developed a more sophisticated method for detection and estimation of mixed paddy rice agriculture from Moderate Resolution Imaging Spectroradiometer (MODIS) satellite data. Previous research demonstrated thatMODIS data can be used tomap paddy rice fields and to distinguish rice from other crops at large, continental scaleswith combined Enhanced Vegetation Index (EVI) and Land...

Accurate information of paddy fields over wide areas is essential to support sustainable agricultural and a food security program. Monitoring of these lands continuously, using remote sensing technology, will provide information related to the cropping intensity in the field, as well as its dynamics change. We characterized seasonal vegetation dynamics from long-term multi-temporal MODIS satell...

The effect of controlled drainage (CD) on ammonia volatilization (AV) losses from paddy fields under controlled irrigation (CI) was investigated by managing water table control levels using a lysimeter. Three drainage treatments were implemented, namely, controlled water table depth 1 (CWT1), controlled water table depth 2 (CWT2), and controlled water table depth 3 (CWT3). As the water table co...

The diversity of cultivable methane-oxidizing bacteria (MOB) in the rice paddy field ecosystem was investigated by combined culture-dependent and fluorescence in situ hybridization (FISH) techniques. Seven microsites of a Japanese rice paddy field were the focus of the study: floodwater, surface soil, bulk soil, rhizosphere soil, root, basal stem of rice plant, and rice stumps of previous harve...

In this study, an algorithm is proposed to determine the duration in a rice crop cycle based on texture analysis. During an observation period in 2013, daily images were acquired from a still camera installed at a paddy field. Given a set of time-series images, the texture analysis is used to classify different stages of the rice growing. Regarding the hypothesis, the rice crop cycle can be sep...

INTRODUCTION Leptospirosis is a zoonotic disease, which has become a major public health threat in Sri Lanka. A majority of patients are farmers in rural endemic areas. The purpose of the present study is to describe the level of knowledge and frequencies of risky practices related to leptospirosis among a sample of rural school adolescents in Galgamuwa, Kurunegala district, a highly endemic ar...
