But in a rain forest, with its abundance and variety of life, those nutrients are reabsorbed almost as fast as they're deposited. In any forest, dead organic matter falls to the ground, providing valuable nutrients for new growth. As with cattle ranching, the soil will not sustain crops for long, and after a few years the farmers have to cut down more rainforest for new plantations. One research station in a Peruvian rain forest counted six hundred species of birds. Clear-cutting is practiced on a large scale by lumber and logging companies. What does contingent mean in real estate? Destroying Nutrients In The Soil When a rain forest is burned to raise crops or cattle, most of the nutrients are destroyed along with the vegetation.

Deforestation in developing nations is primarily due to a competitive global economy, where poorer countries sell their natural resources to pay their debts to wealthy countries. Therefore if the trees are cut down the soil grains are no longer held together by the roots which causes erosion to occur more easily. The forests of Central … This happens for two reasons: first, the loss of soil organic matter, which can store five times its weight in water (Cohen 2003), reduces the soil's total water-holding capacity, and second, extensive plant mortality can diminish water uptake from forest soils (Wondzell et al.

Without the forest canopy to buffer rains and tree roots to cling to the soil… Along with shelterwood and seed tree harvests, it is used by foresters to create certain types of forest ecosystems and to promote select species that require an abundance of sunlight or grow in large, even-age stands. To prevent this from happening, we should cut down lesser trees. Rainforest, luxuriant forest, generally composed of tall, broad-leaved trees and usually found in wet tropical uplands and lowlands around the Equator. Tropical forests move more water than any other ecosystem on land. Deforestation can involve conversion of forest land to farms, ranches, or urban use. As with cattle ranching, the soil will not sustain crops for long, and after a few years the farmers have to cut down more rainforest for new plantations. "Further, this study fills gaps in our understanding of deforestation tipping points -- and what could happen if we continue down this path." This is called leaching of the soil .
