The adoption of conservation tillage technology since the 1970s has been one of the most remarkable changes in the production of crops on the Canadian Prairies. The decision whether to adopt conservation tillage technology or not requires the producer to go through a thorough decision making process. In Canada there has been little economic research on the question of what farm, regional, and e...

ABSTRACT-In conventional agriculture, a large amount of energy is consumed in fuel consumption and depreciation of farm tractors and any other farm equipment mostly in tillage and planting operations. The main purpose of this research was to evaluate a till-planting unit equipped with three jointers. This unit was expected to act as conventional furrow openers such as shovel openers tilling the...

land degradation due to soil erosion has been well pointed out as one of the most serious ecological and economic problems that some such south asian countries including iran are faced with. although high investment has been made, particularly in introduction of soil conservational mechanical practices, the level of acceptance of these practices has been low and while a high rate of erosion con...

A new empirical nitrogen (N) leaching model was applied at detailed agricultural data at field level, obtained from a questionnaire survey including two small catchments. Getting agricultural data from two public electronic registers concerning the 592 km Mariager Fjord catchment, the leaching results were extrapolated from the two reference catchments to the Mariager Fjord catchment, data grou...

No-till acreage has increased in recent years, but many farmers alternate no-till with other tillage practices, limiting public and private benefits from sustained no-till adoption. Revealed preference data are used in an ordered logit regression analysis to determine the effect of soil characteristics, climate, regions, farm characteristics, and producer demographics on producers’ choices to u...

An apparent physiological disease, Yellow Strapleaf (YSL) of Chrysanthemum morifolium Ram., was described by Jackson and Woltz (1) in 1959. The disease has been observed in Florida plantings during the last 6 years and has been noted in Massachusetts 3. Symptoms include chlorosis of new growth, green netting of leaves, and narrow strapshaped leaves that hook at the distal ends (fig 1A). The con...

The purpose of this article is to present the development of a wind farm, with a condition monitoring system (CMS) based on control charts as the algorithm, centred on a new index, to prevent soil pollution by oil spills in wind farms. To this end, temperature sensors can be considered as one of the more significant sensors to be employed in this study, because the information obtained with reg...

The present work was conducted to elucidate the effect of different soil mediums in various ratios on seed germination efficiency and growth of seedling of Simmondsia chinensis under in vivo conditions. The highest germination (94%) was recorded for seeds cultivated in S1 medium containing desert soil and Farm Yard Manure (FYM) (2:1) followed by S4 medium (90%) having desert soil, clay, FYM (1:...
