Explain how fertilisers are different from manure?
Introduction:
Fertilisers and manure are two types of substances used to improve soil fertility and increase crop yield.
Difference between fertilisers and manure:
There are several differences between fertilisers and manure, including:
Sources:
Fertilisers are synthetic compounds that are manufactured using chemicals, whereas manure is an organic substance produced by the decomposition of animal waste and other organic matter.
Nutrient content:
Fertilisers typically contain a specific blend of essential plant nutrients, such as nitrogen, phosphorus, and potassium, in precise amounts. On the other hand, manure is a less concentrated source of nutrients and may contain lower levels of essential plant nutrients.
Timing of application:
Fertilisers are usually applied before planting or during the growing season, as they are designed to provide an immediate source of nutrients to crops. Manure, on the other hand, is typically applied before planting or after harvest, as it takes time for the organic matter to decompose and release its nutrients.
Mode of application:
Fertilisers are usually applied in a concentrated form, either as a dry powder or a liquid solution, which is then mixed with water and applied to the soil. Manure, on the other hand, is typically spread directly onto the soil surface or incorporated into the soil.
Cost:
Fertilisers tend to be more expensive than manure, as they are manufactured using chemicals and require more energy to produce. Manure, on the other hand, is a relatively inexpensive source of nutrients, as it is produced naturally and can often be obtained for free or at a low cost.
Environmental impact:
Fertilisers can have a negative impact on the environment if used excessively or not applied correctly. They can contribute to water pollution, soil degradation, and greenhouse gas emissions. Manure, on the other hand, is a more sustainable source of nutrients, as it is produced naturally and can help improve soil health and fertility over time.
Conclusion:
In conclusion, while fertilisers and manure are both used to improve soil fertility and increase crop yield, they differ in their sources, nutrient content, timing and mode of application, cost, and environmental impact. It is important to use these substances responsibly and in a manner that promotes both agricultural productivity and environmental sustainability.
