Ratios are always given as the % nitrogen (N), phosphorus (P), and potassium (K). For example, a 10-10-20 fertilizer contains 10% nitrogen, 10% phosphorus, and 20% potassium. This means that 100 pounds of this fertilizer will actually contain 10 pounds of nitrogen (10% of 100 pounds), 10 pounds of phosphorus (10% of 100 pounds), and 20 pounds of potassium (20% of 100 pounds). Fertilizer is commonly available in the following ratios: 10-20-20, 15-15-15, 10-10-10, 5-10-5, 5-10-10, 10-20-10, 20-10-10, and 46-0-0. Nitrogen (N) Nitrogen is critical for the maximum growth of cool season grasses in pastures. An adequate supply of nitrogen is associated with vigorous vegetative growth and a plant's dark green color. Reduced plant growth and a pale green or yellow color characterize nitrogen deficiency.

A soil test can be an important management tool in developing an efficient soil fertility program, as well as monitoring a field for potential soil and water management problems. A soil test provides basic information on the nutrient supplying capacity of the soil. However, a test is not reliable if the soil sample is taken incorrectly or is improperly handled after collection. If you need help taking a soil sample properly, see your county Extension agent for publications on the proper soil sampling methods, and for a soil sampling kit. Because analytical techniques vary among laboratories, the number values reported may vary from lab to lab. Numbers used by each have specific meanings for the laboratory. The interpretations discussed here are for the Soil, Plant and Water Testing Lab at New Mexico State University.

Soil ecology From Wikipedia, the free encyclopedia Jump to: navigation search Soil ecology is the study of the interactions among soil organisms, and between biotic and abiotic aspects of the soil environment. It is particularly concerned with the cycling of nutrients , formation and stabilization of the pore structure , the spread and vitality of pathogens , and the biodiversity of this rich biological community Contents Overview Features of the ecosystem Soil food web Research ... edit Overview Soil is made up of a multitude of physical chemical , and biological entities, with many interactions occurring among them. Soil is a variable mixture of broken and weathered minerals and decaying organic matter. Together with the proper amounts of air and water, it supplies, in part, sustenance for plants as well as mechanical support. The diversity and abundance of soil life exceeds that of any other ecosystem . Plant establishment, competitiveness, and growth is governed largely by the ecology below-ground, so understanding this system is an essential component of plant sciences and terrestrial ecology. edit Features of the ecosystem Moisture itself becomes a major limiting factor on land. Terrestrial organisms are constantly confronted with the problem of dehydration. Transpiration or evaporation of water from plant surfaces is an energy dissipating process unique to the terrestrial environment.

Index of pedosphere.com / PEDOSPHERE.COM HOME / ABOUT US SOILS TEXTBOOK SOILS TESTCENTER LEARNING RESOURCES ... CONTACTS About Us Vision Since its inception in 1999, Pedosphere.com aimed to become an extensive repository of Soil Science knowledge through partnerships with major international organizations and also be an active player in global Soil Science education by creating high quality, interactive resources that engage both students and instructors. The development of internet technologies has lead to a glut of information, therefore, there is a tremendous need to organize information, convert it to knowledge and manage the knowledge for specific purposes such as global education. The original aims of becoming key Soil Science knowledge managers and active global educators is now entering its second phase of actualization. Inspiration The most inspiring statement that is driving us is the following excerpt from remarks by His Highness the Aga Khan at the State Banquet (Dhaka, Bangladesh) on 19 May 2008: "Technology is also transforming our economic lives. Economic value is no longer tied to how much land one controls - or how many machines or factories one owns. Within our lifetimes, predominantly "Agricultural Societies" and "Industrial Societies" of the past have been joined - and sometimes supplanted - by what many call the "Knowledge Society," propelled by the digital revolution, and focusing on the creation and management of information. In a Knowledge Society, the most productive investments we can make are investments in education."

97. Soil Erosion Site Collection of information on soil erosion from a wide range of scientific disciplines. http://soilerosion.net

Soil Erosion Site What is at the Soil Erosion Site? About soil erosion Links This website Soil erosion by water, wind and tillage affects both agriculture and the natural environment. Soil loss, and its associated impacts, is one of the most important (yet probably the least well-known) of today's environmental problems BBC 2000 Guardian 2004 "The threat of nuclear weapons and man's ability to destroy the environment are really alarming. And yet there are other almost imperceptible changes - I am thinking of the exhaustion of our natural resources, and especially of soil erosion - and these are perhaps more dangerous still, because once we begin to feel their repercussions it will be too late." (p144 of The Dalai Lama's Little Book of Inner Peace : 2002, Element Books, London) It isn't easy to find comprehensive information on erosion, however. To a large extent this is because soil erosion does not fit neatly under any one heading: it is studied by geomorphologists, agricultural engineers, soil scientists, hydrologists and others; and is of interest to policy-makers, farmers, environmentalists and many other individuals and groups. The Soil Erosion Site brings together reliable information on soil erosion from a wide range of disciplines and sources. It aims to be the definitive internet source for those wishing to find out more about soil loss and soil conservation.
