1. Abstract
This study was done to look at the effects of fertilisers and identify which fertiliser produced the fastest results. Four types of fertilisers were used over a four-week period and the findings were that inorganic fertilisers enhanced seed germination rates.
2. Introduction
Fertilisers are widely used in agricultural production because they contain essential compounds such as phosphorus, nitrogen and potassium that have been depleted from most Australian soil. The phosphorus is responsible for the development of the plants, providing healthy growth and strong roots. Nitrogen furnishes a major component of chlorophyll where it’s known for its ability to grow green leaves. Potassium provides a measure of disease resistance to plants and protection from the cold. (7) Farmers use these nutrients enrich the plants ability to grow and perform its various functions to produce crops. However, these compounds are not always found in the soil because Australia is an old continent and the minerals have been eroded or leached away over countless millennium, so fertilisers are used to replenish the lost nutrients that are needed for a healthy plant-life. (8) (4) Each fertiliser contains different nutrients and amount of concentrations, so depending on what nutrients are required to enrich the soil, the fertiliser will affect the plant-life outcome.
This investigation provides an insight into the use of fertilisers and shows which fertiliser germinates the seeds fastest. Fertilisers are classified into two categories; organic and inorganic. Organic fertiliser is fundamentally the remaining’s of animal and/or vegetable matter whereas inorganic fertiliser is primarily derived from chemical compounds. (6) This experiment will study the effects of different types of fertilisers on mustard seeds. The expectation is that mustard seeds germinated in liquefied fertilisers such as Seaweed and Miracle Growth (a solution
