Burnt Harvest: Penobscot People And Fire, James Eric Francis Sr.
Burnt Harvest: Penobscot People And Fire, James Eric Francis Sr.
Maine History
The scientific and ethnographic record confirms the fact that in southern New England, Indians used fire as a forest management tool, to facilitate travel and hunting, encourage useful grasses and berries, and to clear land for agriculture. Scholars have long suggested that agricultural practices, and hence these uses of fire, ended at the Saco or Kennebec, with Native people east of this divide less likely to systematically burn their forests. This article argues that Native people on the Penobscot River used fire, albeit in more limited ways, to transform the forest and create a natural environment more conducive to their …

A Perspective On Balanced Fertilization In The Mediterranean Region, John Ryan
A Perspective On Balanced Fertilization In The Mediterranean Region, John Ryan
Turkish Journal of Agriculture and Forestry
The demands on agriculture to produce food and fibre are driven by the inexorable increases in the world's population. However, advances in agricultural science in the past century have helped food production to keep pace with population growth, thus keeping hunger and malnutrition at bay. The achievements in enhanced agricultural output, especially in the developed world, are attributed to 3 main factors: expansion of irrigation, development of improved higher-yielding, disease-resistant crop cultivars, and chemical fertilizers. Fertilizers are fundamental to producing more crop output from existing land in cultivation. Along with increased fertilizer use comes greater concern about the environment in …

The Millennium Ecosystem Assessment: Tradeoffs Between Food Security And The Environment, Claudia Ringler
Turkish Journal of Agriculture and Forestry
This paper provides an overview of selected trends and conditions of ecosystem services, in particular, food production and impacts on the environment based on the Millennium Ecosystem Assessment. It then describes outcomes for future ecosystem services under alternative development pathways, with a focus on tradeoffs between food security and the environment, such as implications for fertilizer use, and the role of biofuels. As tradeoffs among various ecosystem services are expected to increase into the future, research will need to focus increasingly on ways to achieve a balance between food security and improving non-food ecosystem services. To reduce adverse future impacts, …
Outlook For World Fertilizer Demand, Supply, And Supply/Demand Balance, Patrick Heffer, Michel Prud'homme
Outlook For World Fertilizer Demand, Supply, And Supply/Demand Balance, Patrick Heffer, Michel Prud'homme
Turkish Journal of Agriculture and Forestry
The outlook is driven by impressive economic growth in Asia, increasing demand for biofuel, and a tight grain market. As a result of tight supply/demand conditions, prices for almost all agricultural commodities are unusually high. The need to boost agricultural production worldwide is stimulating fertilizer consumption in Asia and the Americas, driving global demand to new record levels. For the production of most nutrients 2007 was a record year, as buoyant demand stretched the industry's capacity to meet global requirements. All supply and demand situations will be difficult to balance until 2011 due to sustained fertilizer demand. With nitrogen supply …
Global Economics Of Nutrient Cycling, Bert H. Janssen, Oene Oenema
Global Economics Of Nutrient Cycling, Bert H. Janssen, Oene Oenema
Turkish Journal of Agriculture and Forestry
This paper briefly discusses global human requirements of protein nitrogen (N) from crops and animals, and then estimates the need for fertilizer N as a function of N use efficiency, and the recycling of N from animal manure and sewage wastes. These estimates are based on various assumptions and simple calculations. Results suggest that globally only 1% of N input is retained, 28% is lost to the wider environment, and some 70% is potentially available for recycling via manure and sewage. In addition, large amounts of nutrients recycle via crop residues. In practice, only a fraction of this potential is …
Improving Nutrient Use Efficiency, Terry L. Roberts
Improving Nutrient Use Efficiency, Terry L. Roberts
Turkish Journal of Agriculture and Forestry
Public interest and awareness of the need for improving nutrient use efficiency is great, but nutrient use efficiency is easily misunderstood. Four indices of nutrient use efficiency are reviewed and an example of different applications of the terminology show that the same data set might be used to calculate a fertilizer N efficiency of 21% or 100%. Fertilizer N recovery efficiencies from researcher managed experiments for major grain crops range from 46% to 65%, compared to on-farm N recovery efficiencies of 20% to 40%. Fertilizer use efficiency can be optimized by fertilizer best management practices that apply nutrients at the …
Balanced Crop Nutrition: Fertilizing For Crop And Food Quality, Hillel Magen
Balanced Crop Nutrition: Fertilizing For Crop And Food Quality, Hillel Magen
Turkish Journal of Agriculture and Forestry
Globally the ratio of N:P_2O_5:K_2O changed from 2.5:1.3:1 in the 1980s to 3.6:1.4:1 in 2002 as N consumption outstripped that of K. Regardless of their decreased nutrient consumption, developed countries maintained a modest increase in agricultural production. Positive and similar growth rates for agricultural products and nutrient consumption prevail in developing countries, but with the use of a 35% higher nitrogen (N) to potassium (K) ratio than in developed countries. The outcome of a negative K balance is presented here using examples from India, China, Egypt, and Bulgaria. Reasons for a negative K balance stem mostly from farmers' lack of …

Land Cover Change And Soil Fertility Decline In Tropical Regions, Alfred E. Hartemink, Tom Veldkamp, Zhanguo Bai
Turkish Journal of Agriculture and Forestry
Land cover changes influence the biogeochemistry, hydrology, and climate of the earth. Studies that assessed land cover changes at the global scale mostly focused on: deforestation, cropland expansion, dry land degradation, urbanisation, pasture expansion, and agricultural intensification. For the assessment, remotely sensed land-cover data, census data, and expert knowledge were used. In tropical regions, forest is cleared for the expansion of cropland, wood extraction, or infrastructure expansion. This widely occurs in the Amazon region and in Asia. In many temperate regions, the area under forest is increasing although forest plantations are also on the increase in the tropics. Croplands expanded …
The Effect Of Micronutrients In Ensuring Efficient Use Of Macronutrients, Mohammad Jafar Malakouti
The Effect Of Micronutrients In Ensuring Efficient Use Of Macronutrients, Mohammad Jafar Malakouti
Turkish Journal of Agriculture and Forestry
Micronutrient deficiency is widespread in many Asian countries due to the calcareous nature of soils, high pH, low organic matter, salt stress, continuous drought, high bicarbonate content in irrigation water, and imbalanced application of fertilizers. Some of the adverse effects of micronutrient deficiency-induced stress in plants include low crop yield and quality, imperfect plant morphological structure (such as fewer xylem vessels of small size), widespread infestation of various diseases and pests, low activation of phytosiderophores, and lower fertilizer use efficiency. The absence of micronutrient fertilizers results in inadequate absorption of trace elements by plants, which causes substantial yield losses in …
Micronutrients And Animal Nutrition And The Link Between The Application Of Micronutrients To Crops And Animal Health, George E. J. Fisher
Micronutrients And Animal Nutrition And The Link Between The Application Of Micronutrients To Crops And Animal Health, George E. J. Fisher
Turkish Journal of Agriculture and Forestry
Micronutrients (or 'trace elements') are required in animal diets for health and welfare, and therefore they are essential for the agricultural production of milk, meat, fibre, and eggs. It is clear from the literature that deficiencies of micronutrients, particularly in their sub-clinical form where they are not visually apparent, can result in major reductions in productivity. Micronutrients are used mostly as the central elements of enzymes and co-enzymes in the biochemistry of ruminants and monogastrics. Thus, their deficiency often leads to sub-optimal growth and fertility. Within the farming system, the aim should be to only use supplementation with micronutrients where …
