Abstract A successive 2-year (2019 and 2020) field experiment was conducted in northern Bangladesh (Rangpur district) to observe the status of soil quality heavy metal risk due tobacco cultivation this area. Soil samples were collected randomly from four major sub-districts Sadar, Badargonj, Gangachara, Mithapukur Upazila) where a non-cultivating rests tobacco-growing fields. Along with concent...

Proteolytic fungi from the soil samples were isolated on Reese agar plate containing casein as the protein substrate. The mycoflora of different localities of Sagar and Jabalpur districts of Madhya Pradesh were investigated at three different locations viz. Garden, Crop field and Poultry farms. These samples were labeled according to the site of collection as GS (Garden Soil), CFS (Crop Field S...

This paper presents a model of the farm management process. The model suggests that certain socioeconomic characteristics of farm managers will influence their decision-making process. Several characteristics are hypothesized and tested using multivariate techniques (multivariate analysis of variance, range tests, and multiple comparisons). The analysis indicates that the soil zone, value of ma...

The cigarette companies and their lobbying organization used tobacco industry-produced films and videos about tobacco farming to support their political, public relations, and public policy goals. Critical discourse analysis shows how tobacco companies utilized film and video imagery and narratives of tobacco farmers and tobacco economies for lobbying politicians and influencing consumers, indu...

OBJECTIVE China's food production has increased 6-fold during the past half-century, thanks to increased yields resulting from the management intensification, accomplished through greater inputs of fertilizer, water, new crop strains, and other Green Revolution's technologies. Yet, changes in underlying quality of soils and their effects on yield increase remain to be determined. Here, we provi...

To determine the water application efficiency in furrow irrigation more accurately, consideration of seasonal and spatial variation of infiltration properties are needed. In addition, the effectiveness of different farm management on infiltration are significant. The main objective of this research was to simulate the seasonal variation (SV) of infiltration coefficients in Kostiakov-Louise equa...

Beef producers must consider management strategies and technologies for reducing potential adverse environmental effects of their farms while maintaining or improving profit. One choice is between using perennial grassland or corn as the primary crop on the farm for feed production. Perennial grassland production systems are generally regarded as more favorable due to reduced nutrient losses to...

Dent corn Andisol at the Hokkaido University Shizunai Livestock Experimental Farm actively emits nitrous oxide (N2O). In order to screen for culturable and active N2O emitters with high N2O emission potential, soft gel medium containing excess KNO3 was inoculated with soil suspensions from farm soil samples collected at different land managements. Dominant bacterial colonies were searched for a...

Current fertiliser recommendations for nitrogen are limited in their accuracy and may be improved by the use of simple on-farm soil rapid tests. This paper investigates the potential for using nitrate (NO3) ion selective electrodes (ISEs) and dual wavelength UV spectroscopy as part of a rapid soil NO3 diagnostic test. Three soil types, representing the major soil types for agriculture in the we...

Degradation of agricultural land and the resulting loss of soil biodiversity and productivity are of great concern. Land-use management practices can be used to ameliorate such degradation. The soil bacterial communities at three separate arable farms in eastern England, with different farm management practices, were investigated by using a polyphasic approach combining traditional soil analyse...
