It provides extra nutrients for the plant’s growth and life cycle. It can also increase the soil’s capability to retain water. Organic farms use humus since it is composed of decomposing leaves, another chemical reaction. Humus, which is essential to the soil, balances out the presence of carbon and nitrogen ratio of the soil. It can also retain, remove or lower concentrations of pollutants present in the soil (Royal Society of Chemistry,
Symbiotic Bacteria Bacteria form association with other organisms in which both species get benefit from each other. This type of association is called symbiosis and bacteria are called as symbiotic bacteria. Role of symbiotic bacteria in Nitrogen Fixation Bacteria play a very important role in nitrogen fixation by forming association with many living organisms that require nitrogen to meet their needs. Some associations are given below in which bacteria help in nitrogen fixation. Most of nitrogen fixation is carried out by these bacteria.
In the soil, potassium is attach to CEC or bonded between soil mineral layer which is not accumulate to other ions in soil the solution like phosphorus. Usually ammonium acetate was added to soil to determine exchangeable potassium because it contains high concentration of another cation. The ammonium from the solution pulls out potassium off the CEC and other exchange sites and then measured and used to know the amount of potassium that available for plant during growing
The atmospheric nitrogen are made available to the plants when nitrogen fixing bacteria or rhizobia fixed atmospheric nitrogen and convert them into ammonia (NH3) in the presence of nitrogenase under different conditions such as, in loose association with other organisms, or in a symbiotic manner with them. The process whereby atmospheric nitrogen is reduced to ammonia in the presence of nitrogenase (found naturally in microorganisms viz. Rhizobium, free living Azotobacter etc) is called Biological nitrogen fixation (BNF). The best example for the symbiotic
Introduction: Photosynthesis is a process used by plants and specific types of bacteria in order to make their own food source from sunlight to chemical energy. It is mainly occurred within the leaves of the plant. The reaction requires light energy in order for it to be absorbed by chlorophyll. During the reaction carbon dioxide, water is converted into glucose and oxygen as shown below: Figure 1 (photosynthesis uses light energy to convert carbon dioxide into a carbohydrate) (The Chemical Equation of Photosynthesis. 2018, Accessed 16 March 2018) There are two types of photosynthetic processes; one includes oxygenic photosynthesis, which is most common and demonstrated through plants, algae and cyanobacteria while the other one is an-oxygenic photosynthesis.
Penicillium is one of these fungi as its waste product is often saved and grown on agar plates. This is because the Penicillium waste product can be used as an antibiotic. (penicillin) Fermenters are containers that are used to grow and produce these fungi in large amounts. So the fungi can be used on other things such as making lots of Antibiotics. Fermenters provide a perfect area for fungi to reproduce rapidly as they are in a suitable place for the life processes of fungi to be performed.
Stomata are pores commonly found on the underside of leaves of a plant (stomata study). These microscopic pores are a passageway for carbon dioxide to enter while at the same time allow water and oxygen to be released (berkley). Plants need stomata as they allow the plant to take in carbon dioxide, a necessary part of photosynthesis (berkley). Plants open stomata by their guard cells located on either side of the stomata (stomata study). These cells can swell up to open the stomata or deflate to close them off (berkley) This is important because any time stomata are open the plant will lose water along with oxygen (berkley) When enough carbon dioxide has entered the stomata, a plant will close its stomata so it can preserve its water and prevent
They are helpful because some bacteria are decomposers making nutrients available for other organisms from dead organic matter and from recycling nutrients, they are sustaining a balance in the ecosystem. In the environment, bacteria are also nitrogen fixers, converting nitrogen in the atmosphere into nitrogen compounds that plants are able to use for growth, therefore they are significant contributors to the nitrogen cycle. An example of a plant would be legumes, in which these types of bacteria live in their root nodules, supplying them with nitrogen compounds for their growth. This is also an example of a mutualistic relationship, where most species would live in a close relationship with bacteria, helping them in survival and benefiting them from this close relation. Such as, the E.coli bacteria that live in our intestines where we would provide them with a warm and a safe place to live, an abundance of food and a source of transportation and they would provide us with vitamins and nutrients that we cannot make on our own as well as helping us digest our food.
 Moisture determination is an important indicator of the fertilizer 's quality. Nutrient content is dependent on the amount of moisture it contains. It is necessary to grind the sample so that fineness desired for the experiment is achieved. In this experiment, gravimetric method of analysis was used. Gravimetric analysis is a method that involves precipitating and weighing the mass to determine how much of a certain substance is present.
When making compost tea it is important to know the percentage of oxygen in the compost tea because it will determine whether the compost tea will go aerobic or anaerobic. Oxygen is an essential source of life for aerobic organisms. As Ingham (2010) explained ,to get an aerated compost tea oxygen’s level should be more than what the organisms consume, in other words, above 6ppm, moreover, this amount of oxygen will provide an environment for aerobes such as Bacillus and pseudomonas which are highly important for soil to thrive. Another important point to mention, to infuse oxygen into compost tea you should use bubblers that provide small air bubbles. Since, the smaller the bubbles, the more oxygen is transferred into water.
