Soil salinity control

gases. “Soil biological processes have major long-term effects on composition of Earth’s atmosphere, which in turn influences all living things, including soil microorganisms” ( Brady, Weil 2008). Changes in atmospheric concentrations of carbon dioxide, temperature, and precipitation amounts and patterns will modify the soil plant system, and influence decomposition rates which will have impacts…

Within recent decades, there has been an experience in the decrease of the soil health and fertility around the world. There are many causes to this, which will be explained later on into this essay. This is a problem that needs to have more focus put on it because soil health and fertility is arguably the basis for all of our foods and without having healthy and fertile soil, there will be a decrease in the amount of crops produced. But not only is the amount of crops produced affected, the…

Soil erosion is one of the most serious threats in our world. Humans cause 40% of soil erosion. Soil erosion is topsoil, which is organic soil made up with rich nutrients. Erosion can be caused by careless farming techniques that lead to water erosion. When it is raining and you are walking to class you can see soil erosion where they have been working beside the English building. Soil erosion and water erosion is practically the same thing. No one will ever notice soil erosion because nobody…

utilized agricultural, animal and human residue as fertilizer (Howard, 1943, Food and Agriculture Organization, 1978). Many of these residues either were placed in pits or placed in heaps and allowed to rot for long period of time for the production of soil amendment. The first waste pits made out of stone and built outside the houses were found in Sumerian cities about 6000 years ago (Uhlig, H. 1976). India is characterized by a mosaic of distinct agro-ecosystem conditioned by its geological…

Plant Science - Seed germination and growth The research question: What is the effect of changing the pH of the soil on the germination and growth of mustard peas? Hypothesis: The greatest number of peas will germinate and will grow the most when the pH is 5 or 7. Theory: Enzymes play a vital role in the cells of plants (especially when growing) and enzymes work best when at their optimum pH value. Moreover, all chemical reactions have an optimum pH at which they work best (Howard and…

Imagine living in the dream home that you created as a child? Taking control over the design process makes the designing of your home a more engaging, fulfilling and personal experience. Nevertheless, you cannot just start designing without taking a few aspects into consideration because these seemingly tiny slips can add more value to your home. Renovations have become more popular. In fact, the Westpac Renovation Report from 2014 shows that home renovations had increased as much as 147 percent…

Soil preference of the Red Compost Worms, Eisenia fetida INTRODUCTION Earthworms provide countless benefits to humans, plants and animals, by improving drainage, advancing nutrient accessibility, and providing a steady soil system, helping to develop farm production. They benefit the soil ecosystem by decomposing and recycling organic matter, opening up pores inside the soil to develop its formation and supplying food for predators . By adding nutrients to the soil they inhabit, earthworms are…

A raised plant bed is elevated and sits higher than the its surrounding ground. Many things can interrupt the ability of plant growth in a raised garden bed: materials, bugs, and even the products that are being used. To some extent, we can control how strong we want our plants to grow. The most modern stage in the development of plant bed design today for raised beds filled with fast draining planting mix, which are ideal growing environments for vegetables. Therefore, using a deeper plant bed…

To be specific, it helps control the “regulation of vascular tone, homeostasis of blood pressure and proliferation of vascular smooth muscle cells” (CITE). The hempseed has a rich content of linoleic acid, which reduces the cholesterol level of the body, and low cholesterol helps…

Nowadays, urban growth has become a big treat to the environment. The transportation and the construction of facilities have introduced different kinds of invasive species in Seattle. Moreover, the illegal waste dumping and lack of maintenance also help spreading the invasive species. The common invasive species in Seattle are English Ivy, Himalaya Blackberry, American Bull Frog and fox squirrel, etc. The invasive species usually compete and edge out the native species. After a period of time, a…
