There are several different types of governments in this world. The United States run on a democracy. To have a successful democracy there needs to be a strong civil society‚ widespread education‚ active citizen participation‚ a social consensus and a favorable economy. The three most important of these five are having a favorable economy‚ widespread education and a strong civil society. The economy is an important factor of a government. Since the U.S has a government‚ like Abe Lincoln said

Chemical Fertilizers vs. Organic Fertilizers INTRODUCTION Agriculture is the most primitive occupation of the people which mainly needs land to grow different crops for food and as raw materials for different industries. Industrial use of agriculture for supplying raw materials came much later. Originally land was used for agriculture to supply food for human beings by the use of organic manures particularly animal dung. At the beginning land was used in its natural form to grow food. Land contains

plant growth and sustainable soil management. Phosphorus nutrition can be challenging in acidic soils (e.g. Queensland) and alkaline soils (e.g. South Australia). To achieve sufficient nutrition‚ the soil needs to have a relatively high pH‚ high organic matter content‚ and moist conditions. Specific soil orders such as Vertosols‚ Kandosols‚ Sodosols‚ Rudosols‚ and Calcarosols‚ lack the requirements for phosphorus nutrition. The availability of phosphorus heavily relies on soil pH; the pH range for highest

piles driven side by side into the ground‚ thus forming a continuous vertical wall for the purpose of retaining an earth bank. They are commonly used for: (1) water front structures‚ (2) temporary constructions‚ (3) light weight construction where sub soil is poor for supporting a retaining wall. A sheet pile may be of three types: Cantilever sheet piling Anchored sheet piling Braced sheeting Cellular cofferdams The design of sheet pile retaining walls requires several successive operations:

the uptake of nutrients such as P‚ N‚ K‚ Cu‚ Zn and Ca by plants especially in soils low in these nutrients. Since P is the most limiting nutrient in tropical soils‚ mycorrhizas are vital for improving P nutrition particularly for cultivated plants. External hyphae can absorb and translocate P to the host from soil outside the root depletion zone. The thin mycorrhizal hyphae (2-4 μm in diameter) are able to penetrate soil pores not accessible to the root hairs which are about five times larger than

Some of the major effects of deforestation include biodiversity loss‚ local climate change and global warming. Farmers often have trouble raising crops‚ which typically results in more problems‚ such as an increase in food prices. Soil erosion and cultural displacement also can occur. Those who want to address the problem have a variety of options‚ however. Biodiversity Loss A loss of biodiversity often follows a reduction in the amount of forested land. Trees‚ shrubs and other plants provide shelter

Humans also greatly contribute to erosion. Because of humans‚ the Earth has gone through millions of years of farming‚ cutting down trees‚ and the development of architecture. Humans drastically changed the earth so much‚ that every year one million acres of top soil
