hypothesized that nitrogen would cause a greater algal growth rate due to its higher abundance required in plant growth. Nitrogen and phosphorous were tested separately‚ where the concentration of each was increased while the other remained constant. The results showed a positive increase in algal growth rate in the phosphorous samples and a negative relationship with increased nitrogen levels. In this way‚ phosphorous acted as the more significant nutrient in algal growth and should be controlled to prevent

What is intensive plant production? Well it is formally known as intensive agriculture. It is an ‘Agricultural production system characterised by the high inputs of capital or labour relative to land area’ [http://www.uwa.edu.au/__data/assets/pdf_file/0009/92619/Yan_PPS_Workshop.pdf]. It mainly focuses on produces with the highest amount of value. Around the world‚ intensive agriculture is needed and in the entire generality of agriculture‚ intensive agriculture takes up about 37%‚ specialising in

Waste management is important and crucial to humans. It is actually the collection‚ storage‚ processing‚ disposing‚ and recycling of waste products. These waste products are mainly of household waste‚ industrial waste‚ nuclear power plants and so on. The problem of improper waste management is on the rise from day to day. If the waste products are not managed properly‚ it will cause a lot of bad influences to humans. The effects of improper waste management to humans are contamination of soil‚ floods

Upon consultation with a professor involved in the forum‚ it was found out that funding for local researches is still unavailable and the objective of the government has shifted to researching on the production of high-value algal products. Costs of production is the primary reason why microalgal biofuel is still deemed uneconomical for commercial production but researches on determining the most efficient methods for production utilizing the most efficient lipid-producing
