1. Source: Organic fertilizers are derived from natural sources such as animal manure, compost, and plant materials. Inorganic fertilizers, on the other hand, are synthetically manufactured using chemical compounds.
2. Nutrient content: Organic fertilizers generally have lower nutrient content compared to inorganic fertilizers. They release nutrients slowly over time as they break down, providing a more balanced and sustained nutrient supply to plants. Inorganic fertilizers, on the other hand, have higher nutrient concentrations and provide an immediate nutrient boost to plants.
3. Nutrient availability: Organic fertilizers release nutrients slowly as they decompose, making them available to plants over a longer period. Inorganic fertilizers, being water-soluble, release nutrients quickly and are readily available for plant uptake.
4. Soil health: Organic fertilizers improve soil health by enhancing its structure, increasing microbial activity, and promoting nutrient cycling. They also help in retaining moisture and improving soil fertility in the long term. Inorganic fertilizers, however, do not contribute to soil health and can even lead to soil degradation if used excessively.
5. Environmental impact: Organic fertilizers are considered more environmentally friendly as they are derived from natural sources and do not contain harmful chemicals. Inorganic fertilizers, especially when overused or misused, can contribute to water pollution, soil degradation, and harm beneficial organisms.
6. Cost: Organic fertilizers are often more expensive than inorganic fertilizers due to the higher costs associated with their production and sourcing. Inorganic fertilizers, being mass-produced, are generally more affordable.
7. Long-term effects: Organic fertilizers improve soil fertility and health over time, leading to sustainable and long-lasting benefits. Inorganic fertilizers, if used excessively or improperly, can lead to nutrient imbalances, soil acidification, and reduced soil fertility in the long run.
