At present, Biodiesel fuel is about one and a half times more expensive than petroleum diesel fuel. It requires energy to produce biodiesel fuel from soya crops, plus there is the energy of sowing, fertilizing and harvesting. Another biodiesel fuel disadvantage is that it can harm rubber houses in some engines.

Why My pond water is green?
Green pond water is caused by tiny floating algae, which grow explosively. Additional effects are low CH value, high pH value and stagnation in growth of oxygen producing plants. Green pond water frequently occurs in newly built ponds containing water rich in food.
Does Salt Water prevent algae?
If you own a salt water pool, you probably know how big of a problem algae growth can be. Once these organisms contaminate the pool, they can grow and spread quickly. Both chlorinated and salt water pools need proper water chemistry levels in order to prevent algae growth.

What are the major disadvantages associated with HYV seeds?
Biggest disadvantage associated with HYV seeds is bigger requirement of water and also chemical fertilisers and pesticides to produce best results. 2. Higher yields are possible only from combination of HYV seeds irrigation chemical fertilisers pesticides etc.
Is algae harmful or helpful?
There are thousands of species of algae; most are beneficial and only a few of these produce toxins or have other harmful effects. Harmful algal blooms are blooms of species of algae that can have negative impacts on humans, marine and freshwater environments, and coastal economies.
How do you kill algae without killing plants?
Eradicating algae infestation without harming other plants in the pond involves drastically reducing the amount of nutrients available to algae. Algae are present whenever and wherever there are abundant amounts of nutrients. So, cutting their food supply can effectively kill them.
What are the pros and cons of algae?
Pros and Cons of Algae Biodiesel
- A Renewable Resource. Unlike coal, natural gas and petroleum, oil derived from algae is a renewable resource.
- Algae Biodiesel is Carbon Dioxide Neutral.
- Efficient Land Use.
- High Water Use.
- High Fertilizer Use.
- High Cost of Algae Biodiesel.
Should I clean the bottom of my pond?
Muck is ok in natural wildlife ponds but in ponds containing fish, it can lower oxygen levels and encourage algae growth. A lined fish pond shouldn’t have any detritus on the bottom, dealt with by a combination of filtration and maintenance.
Is algae good for soil?
Yes. Because pond scum and algae are living organisms, they are rich sources of nitrogen that break down quickly in the compost pile. Using pond scum as fertilizer also incorporates important nutrients, such as potassium and phosphorus, into the compost.
What are the benefits of cellulosic ethanol as compared to corn ethanol?
The United States Department of Energy concludes that corn-based ethanol provides 26 percent more energy than it requires for production, while cellulosic ethanol provides 80 percent more energy. Cellulosic ethanol yields 80 percent more energy than is required to grow and convert it.
Will Salt kill algae in a pond?
Other than placing your pond in a shady area where it does not receive ample sunlight, you can use rock salt to kill algae. of rock per 1,000 gallons of water to kill the string-like algae. Use caution when using salt as it can kill plants and fish in the pond. Remove the plants from the pond before adding the salt.
How do humans benefit from algae?
In addition to making organic molecules, algae produce oxygen as a by-product of photosynthesis. Algae produce an estimated 30 to 50 percent of the net global oxygen available to humans and other terrestrial animals for respiration.
What are the disadvantages of bioethanol?
Drawbacks of bioethanol include: The amount of arable land needed to grow the crops in order to produce a large amount of fuel is immense. This could greatly impact the biodiversity of our environment as we could see natural habitats being overrun, including forests.
How is cellulosic ethanol beneficial for both the environment and the farmer?
Cellulosic ethanol has the potential for lower life-cycle greenhouse gas (GHG) emissions compared with either corn ethanol or petroleum gasoline. (2012) estimated life-cycle energy consumption and GHG emissions from using ethanol produced from five feedstocks: corn, sugarcane, corn stover, switchgrass, and miscanthus.
Does cinnamon kill algae?
How to remove algae: Sprinkle a little cinnamon on the algae.
