Pros and Cons of Fertilisers
Every gardener has his/her own take on whether they should use organic or chemical fertilisers, and this could spark quite a debate. If you had to take the argument to the plants, they probably wouldn’t care. Both have nutrients, and that is what the plants like and need. Although it’s all the same to plants, the farmer has more to consider. Let’s look at the pros and cons of both methods.
Organic fertilizer is made from powdered minerals and natural waste from plants and animals, like bone meal, cottonseed meal, manure and compost. These fertilisers are usually sold as ‘soil conditioners’ because nutrient ratios are not guaranteed.
• Low risk of toxic build-ups that can be dangerous to plants
• Difficult to over fertilize
• Renewable, sustainable, environmentally friendly and biodegradable
• Can be inexpensive
• Sustains the soil long-term
• The need for warmth and moisture makes organic fertilisers seasonal
• It takes a long time to become effective
• Nutrient ratios are not always known and generally lower than chemical fertilisers
Also called synthetic, manufactured and inorganic fertilisers, chemical fertilisers are constructed with exact nutrient ratios.
• Improvement happens quickly because nutrients are immediately available to plants
• Exact nutrition ratios give a higher level of certainty about results
• Not environmentally friendly as it is mainly made from non-renewable materials like fossil fuels
• The soil is not sustained and can be damaged in the long-term
• Over fertilization can kill plants and upset the eco-system
• Toxic build-up happens in the soil and make its way into fruit and veggies
• Long-term use changes the pH of the soil
The choice is yours
You can choose to have big and beautiful crops at the cost of what happens to the soil in future years, or make a more conscious choice and live in harmony with the earth. If you look at it closely, organic fertilizer far outweighs its chemical counterpart.
