Answer questions - Coursework Example The acquisition cost of seed or cuttings should also keep in mind. Planting of most fruit trees, for example, are expensive. Some species are harder to adjust than others. Farmers should consider in advance how long they should take care of trees. If they need additional skills and knowledge to grow a particular species should be training or demonstration will be organized. Seeds or plants of the species considered easy. If asexual reproduction is necessary, farmers should receive training on how to do it. The seeds of Gliricidia sepium and Sesbania spp. For example, could not be readily available. Farmers need help with how to distribute the trees using root cuttings. They may not even enough time for the harvest of cuttings. Question 2 Role of trees or roots of fig trees is no different than any other plant. Edible fig (Ficus carica) roots, for example, grow best in fertile soil rich in organic matter that is moist but never soggy. Roots have four functions. Anchoring the plant fig s, absorbs water and nutrients for plant growth and flowering and fruiting activities, in the case of tropical fig trees, aerial roots hanging from the branches to improve weight distribution of the structure.Picture of the roots can grow to a diameter of branches to see above the ground. Fig trees do not grow the carrot-like tap roots, but the diffuse array, or weaving roots penetrated the body of at least two or three times as much as the diameter of the crown of the plant. Like when you snap a branch of plant leaf figs, or milky sticky sap oozing from broken roots Fig. Some species tropical fig tree roots "are growing rapidly and are known to lift sidewalks or pavement, which spread across the landscape. Question 3 Carbon sequestration in the agriculture sector refers to the capacity of agriculture lands and forests to remove carbon dioxide from the atmosphere. Carbon dioxide is absorbed by trees, plants and crops through photosynthesis and stored as carbon in biomass in tree tru nks, branches, foliage and roots and soils. Forests and stable grasslands are referred to as carbon sinks because they can store large amounts of carbon in their vegetation and root systems for long periods of time. Soils are the largest terrestrial sink for carbon on the planet. The ability of agriculture lands to store or sequester carbon depends on several factors, including climate, soil type, type of crop or vegetation cover and management practices. The amount of carbon stored in soil organic matter is in?uenced by the addition of carbon from dead plant material and carbon losses from respiration, the decomposition process and both natural and human disturbance of the soil. By employing farming practices that involve minimal disturbance of the soil and encourage carbon sequestration, farmers may be able to slow or even reverse the loss of carbon from their ?elds. In the United States, forest and croplands currently sequester the equivalent of 12 percent of U.S. carbon dioxide emissions from the energy, transportation and industrial sectors. Question 4 Major reasons of the changes in the forested land due to human reasons include: industrialization, suburbanization, land trust movements and settlements and agriculture. Question 5 Pleistocene climate was characterized by repeated glacial cycles where continental glaciers pushed to the parallel 40 in some places. It is estimated that glacial
