Organic farming for cereal crops production has several limitations:

1. Yield Variability:Organic farming often produces lower yields compared to conventional methods due to limitations in nutrient availability and pest control methods. This can result in inconsistent production and may not meet the demands of a growing population.

2. Weed Control: Organic methods primarily rely on mechanical weed control, which can be time-consuming and labor-intensive compared to chemical weed control used in conventional farming.

3. Nutrient Management: Organic fertilizers take longer to release nutrients, making it challenging to provide immediate and adequate nutrition to crops. This slower nutrient availability might lead to deficiencies, affecting crop growth and yield.

4. Pest and Disease Management: Organic farming relies on natural methods, such as crop rotation, biological pest control, and resistant crop varieties. However, these methods might not always offer complete protection, leading to potential losses in yield.

5. Land Requirement: Organic farming often requires more land than conventional methods to achieve similar yields due to lower nutrient density in organic fertilizers and the need for diverse crop rotations to maintain soil fertility.

6. Market Demand and Cost: While there's a growing demand for organic products, they often command higher prices due to the increased labor, certification, and management costs associated with organic farming practices.

7. Research and Innovation: Compared to conventional farming, organic farming might have limited access to technological advancements and research-based solutions for crop improvement, which can impact productivity.

Despite these limitations, organic farming promotes environmental sustainability, biodiversity, and healthier soil, making it an attractive choice for many consumers and farmers concerned about long-term ecological impacts.

Lower Yields: Organic farming often yields lower quantities of cereal crops compared to conventional methods, primarily due to the slower release of nutrients from organic inputs and limited use of synthetic fertilizers.

Vulnerability to Pests and Diseases: Organic practices may be more susceptible to pest and disease pressures, leading to potential crop losses and challenges in maintaining high yields of cereal crops.

Limited Nutrient Availability: Organic fertilizers may not provide a quick and easily accessible supply of nutrients, impacting the immediate nutrient needs of cereal crops during critical growth stages.

Crop Rotation Challenges: Organic farming relies on crop rotation to manage pests and diseases, which may limit the continuous cultivation of high-demand cereal crops, affecting overall production.

Dependency on Weather and Climate: Organic farming practices can be more reliant on natural processes, making cereal crops more vulnerable to weather fluctuations and climate variations, impacting yields.

Time-Consuming Weed Management: Organic farming relies on mechanical and cultural methods for weed control, which can be time-consuming and labor-intensive, potentially affecting the overall efficiency of cereal crop production.

Market Challenges: The demand for organic cereals may not always match conventional production levels, and market access can be limited, affecting the economic viability of organic cereal farming.

The major limitations of organic farming on cereal production include slow release of the nutrients to meet quick demand for growth of cereals as well as the difficulty in getting large quantities of the organic fertilizers for such fields.. Nevertheless,in my deep research works,l have developed liquid fertilizers from the bulky solid organic fertilizers named plant and animals manure tea fertilisers which have helped to release nutrients to the crops quickly for good crop yields as well as reducing the problems of bulkiness . Besides,the application of organic fertilizers to the soils before planting will enhance their decomposition as well as releasing both macro and micro nutrients to the soil which will enhance the general soilfertility and it can support growth of many crops (multiple cropping).This is the principle of soil fertilization unlike,the conventional crop fertilization which is applying fertilizers to individual crop after planting .ln addition, the organic fertilizers increase soil organic matter and improve soil properties such as soil pH, Cation exchange capacity and base saturation which the use of conventional chemicals destroy on continuous use. The use of organic fertilizers increase the CEC of tropical soils mainly Kaolinitic Clay minerals and release more nutrients unlike the conventional chemical fertilizers which destroy soils. The use of soil fertilization approach for organic fertilizers which focusses on general soil fertility will encourage crop rotation practice.The problems of organic fertilizers harbouring pests can be solved by proper curing process to enhance quick mineralization., also, do not apply wet organic fertilizers. The problems of weeds infestation can be solved by planting high vigour plants,using correct spacing for crops and planting cover crops to suppress weeds growth .The gains of eating organically produced foods for healthy living out weight the foods produced by conventional chemical fertilizers.Finally, the cost of re setting soil equilibrium destroyed by the use of conventional chemical fertilizers is huge and disastrous for sustainable agriculture being promoted for food security

In addition to the above, the cost implication considering the relatively high volume of the soil amendments and requirements to be used if one is to avoid the conventional fertilizers, pesticides and other inputs.

The limitations of organic farming for cereal crops production include lower yields compared to conventional methods, susceptibility to pests and diseases without synthetic interventions, and challenges in nutrient management, leading to potential imbalances. Additionally, the reliance on organic inputs and the transition period for certification may pose practical and economic constraints for some farmers.
