Soil Pollution In Africa

The company’s upstream operations were affected more by the decline in crude oil prices since it resulted in reduced revenues and impairments worth $ 1.96 billion triggered by a downward revision in the company’s longer-term crude oil price outlook. The company reported a loss of $ 2.2 billion from its upstream business. Production in the upstream segment increased 2 % from 2.55 million barrels per day to 2.60 million barrels per day in the second quarter. This increase in production was the result of increased production capacity in the facilities in US, Bangladesh and Argentina

Another benefit of composting is that it can reduce the amount of times you need to water your plants. Since the nutrients get absorbed you don’t need to water your plants many times. This could reduce the amount of water being used to water plants. As Mississippi University “nutrients that are absorbed by composting can reduce the number of times you need to water plants”. As Mississippi University said, it proves that composting is great way to have rich soil.

In this case, the no nitrogen had leaves that had brown and yellow pigments and the leaves were not healthy. The leaves were wrinkled and smaller. High nitrogen plants tend to make the plant not have proper growth in leaves. Having a lot of the macronutrient causes the plant to be very light and thin but it does grow faster than the low nitrogen and no nitrogen. To create the healthiest Helianthus annuus plants, the right amount of sunlight, water, and the nutrients are needed.

Soil erosion happens more frequently on a larger scale when there is little vegetation on land. Plants shield the rainfall impact and splash, thus letting the water spread slowly into the soil and reducing the rainfall impact. The plant type is crucial in order to have the least amount of soil erosion. Plants that have fibrous root are known to be one of the best kinds to reduce soil erosion such as the grass. During a rainfall, soil erosion is evident and is concerned more.

Transpiration is nothing but the the loss of water due to evaporation through tiny pores on the leaf surface. When water is available to the roots they move into the plant through a process called osmosis and this creates a pressure in the root called the hydrostatic root pressure and this pressure forces the water upward but only for a short distance, the rest of the force to push the water up to the leaves is due to transpiration. The water loss is facilitated by the opening and closing of the stomata depending on environmental conditions. A stomata is nothing but the small invisible pores on the leaves. Transpiration is a very important part of the water cycle as it helps in keeping the air moist and this is beneficial to humans.

This experiment will also show if fertilizers help a plant grow more than just soil found in nature. This experiment will not try to prove if chemical fertilizer is safe or not. The chemical fertilizer being used was randomly chosen and the compost will be made from scratch. There are positive and negative effects on the plant from using both these fertilizers. The best result will be determined through daily measurements and general observations of the appearance of the

The PH of the soil: Soil PH is simply a measure of how acid or alkaline the soil is on a scale of 1-14 , and soil acidity or alkalinity (soil pH) is important because it influences how easily plants can take up nutrients from the soil; thus indicating the health of the soil. from 6.0 to 7.5. Below pH 6.0, some nutrients, such as nitrogen, phosphorus, and potassium, are less available. When pH exceeds 7.5, iron, manganese, and phosphorus are less available. Macro-organisms found in the soil: If a lot of worms or other organisms are found in the soil, it will indicate that the soil is most probably healthy enough for the access of people as it is not to acidic or alkaline to contain life because Earthworms need moisture and nutrients.

• Better tasting food starts with better water • RO systems do not consume energy, making them energy efficient. • The maintenance is pretty simple. The cons of reverse osmosis systems is: • They can be some clogging • Takes patience and time because reverse osmosis works through the use of household water pressure and it does require time to go through the membrane as well as refill the tanks. • You’ll need to replace water filters. Though it it isn’t super expensive it is an ongoing maintenance item.

Phosphate can come from some agricultural fertilizers, manure, and organic wastes in sewer. If there is too much phosphorus in water then it can increase the abundance of plant life, which can be good for the aquatic plants, but could lead to suffocating the creatures in the water since the oxygen will be used up. The further away the water source is from civilization, the less unnatural ions will be present in

GM crops can be grown on smaller spaces of land, decreasing the pressure placed on the limited space the world has for crops which is already a problem. GM foods can be more environmentally friendly as they require less herbicides and pesticides. Even though there are advantages there are multiple disadvantages which make the decision difficult. They are found to be dangerous to insects which don’t feed on the crops but that are equally important as they play roles in our ecosystem. GM foods can possibly change the field of agriculture.
