Advantages of Organic Fertilizer
- Organic fertilizers, besides releasing nutrients for plant’s growth also improves soil structure. The continuous application of organic fertilizer will improve water and nutrients retention of the soil and improve activities or beneficial soil organisms.
- Organic fertilizers release nutrients slowly and so it is difficult to over fertilize and harm your plants.
- You avoid the condition of the toxic build up of chemicals and salts. These chemicals and salts are not good for plants. Moreso, they can wash into nearby waters and underground waters, making them unhealthy for consumption by man or animals.
- Organic fertilizers are environmentally friendly and sustainable. Also, they are renewable and biodegradable.
- Organic fertilizers can be made from household biodegradable waste such as kitchen waste, plant leaves and other plant residues. .
Disadvantages of Organic Fertilizer
- Organic fertilizer takes some time to break down and so releases nutrients slowly. This does not help in the quick recovery of crops.
- It is bulky. Nutrient levels in organic fertilizers are relatively low and so requires relatively large quantities to reach plants requirements.
- Microorganisms require warm and moist conditions to break down release nutrients. During the dry and cold seasons, the activity of microorganisms is substantially reduced and so the effectiveness of fertilizer is limited.
