Q1. You are asked to create soil that would be considered very fertile. What would you include in your "recipe?" I would try to create a soil order all of my own‚ combining Inceptisols and Mollisols unique characteristics. My terrain for my soil to be placed would be on a mostly flat to gently sloping surface to provide good drainage‚ minimum erosion‚ and sufficient time for nutrients to drain into the soil. My “O” soil horizon will be mostly compost made from fallen leaves and other organic

Soil formation‚ or pedogenesis‚ is the combined effect of physical‚ chemical‚ biological and anthropogenic processes on soil parent material. Soil is said to be formed when organic matter has accumulated and colloids washed downward‚ leaving deposits of clay‚ humus‚ iron oxide‚ carbonate‚ and gypsum. As a result‚ horizons form in the soil profile. These constituents are moved (translocated) from one level to another by water and animal activity. The alteration and movement of materials within a soil

Title L6 – Soil Permeability – Constant Head Test Introduction Permeability is measured in term of water flow through the soil in a given time. The soil permeability is a very important factor to study the behavior of soil in its natural condition with respect to water flow. The size of pore space and interconnectivity of the spaces help determine permeability‚ so shape and arrangement of grains play a role. Often the term hydraulic conductivity is used when discussing groundwater properties

Kenneth R. Sagum May 7‚ 2013 FR1 NATSCI1 “Effects of Soil Erosion in the Philippines” The soil is among our most precious resources‚ yet we often take it for granted or destroy it by making it susceptible to soil erosion. In the Philippines‚ for example‚ 22 provinces had been reported to have "alarming" soil erosion rate. Among those that had been losing their topsoil were Cebu‚ Batangas‚ Marinduque‚ Ilocos Sur‚ and La Union. This means that 58 per cent of the country’s total

When I was researching for this essay explaining what soil and water conservation means to me‚ I found two quotes that really stuck out to me. One written by Franklin D. Roosevelt stated‚ “A nation that destroys its soils destroys itself. Forests are the lungs of our land‚ purifying the air and giving fresh strength to our people.”‚ and another that was written by an unknown author read‚ “Water is life’s mater and matrix‚ mother and medium. There is no life without water.” I am not sure about you

Soil erosion Soil erosion occurs when soil is removed through the action of wind and water at a greater rate than it is formed SOIL The soil covering the surface of the earth has taken millions of years to form and we must learn to respect it. Soil is formed at a rate of only 1 cm every 100 to 400 years and it takes 3 000 to 12 000 years to build enough soil to form productive land. This means that soil is a nonrenewable resource and once destroyed it is gone forever. If we disregard this‚ a

Alkaline soil is referred to by some gardeners as”sweet soil”. The pH level of alkaline soil is above 7‚ and it usually contains a great deal of sodium‚calcium and magnesium. (1) Alkaline soil occurs in areas with high limestone content‚ easy souble phosphorus and calcium binding‚ formation of insouble calcium salts of phosphorus‚ reducing the effectiveness of phosphorus. Also‚ in calcareous soils‚ boron‚ manganese‚ molydenum‚ zinc‚ iron greatly reduces the effectiveness of the crop often feel inadequate

SOIL NAILING INTRODUCTION: Since its development in Europe in the early 1970s‚ soil nailing has become a widely accepted method of providing temporary and permanent earth support‚ underpinning and slope stabilization on many civil projects in the United States. In the early years‚ soil nailing was typically performed only on projects where specialty geotechnical contractors offered it as an alternate to other‚ conventional systems. More recently‚ soil nailing has been specified as the
