Introduction

In the era of globalization, agricultural land has narrowed due to the transfer of function to become non-agricultural. Therefore, agricultural intensification is needed to optimize the use of existing land. Intensification involves a series of land treatment activities to improve agricultural output. One of the key factors in agricultural intensification is the use of fertilizers and organic matter, such as rice straw, to improve soil fertility and increase crop yields.

The Importance of Rice Straw in Soil Fertility

Rice straw, as residual harvest, can improve the physical, chemical, and biological properties of the soil. The availability of rice straw varies between 2 to 8 tons/ha per planting season, depending on the varieties and methods of processing. Unfortunately, many farmers still choose to burn rice straw, so that it has the potential to harm health and ecosystems. Burning straw results in loss of important elements such as CO2, CO, and NO2.

Rice straw contains significant organic material content, with a composition of about 40% carbon (C), 0.6% nitrogen (N), 0.1% sulfur (S), and 1.5% silica (Si). The high carbon content in rice straw makes it a valuable source to increase soil fertility. Returning rice straw to paddy fields can help supply nutrients needed by plants, while reducing pollution from burning. This is in line with research Setyanto (2008) which shows that the use of straw as an organic material can prevent the release of CO2 in large quantities to the atmosphere.

The Role of Fertilizers in Soil Fertility

Fertilizers play a crucial role in maintaining soil fertility and increasing crop yields. However, the overuse of chemical fertilizers can have negative impacts on soil health, including soil degradation, water pollution, and loss of biodiversity. Therefore, it is essential to use fertilizers in a balanced and sustainable manner.

The Impact of Rice Straw and Manure on Soil Fertility

Utilization of rice straw and manure in the SRI planting system can have a significant positive impact. First, increasing the content of essential soil nutrients for plant growth. Rice straw that is processed into green fertilizer can improve soil structure, increase the ability of water retention, and enrich soil microorganisms.

Second, by utilizing rice straw and manure, farmers can reduce dependence on chemical fertilizers that often have a negative impact on soil health. Third, the SRI planting system that prioritizes the principle of efficient use of resources can increase the productivity of paddy rice in a sustainable manner.

Analysis of the Impact of the Use of Rice Straw and Manure

The use of rice straw and manure in the SRI planting system can have a significant positive impact on soil fertility and crop yields. The benefits of using rice straw and manure include:

Increased soil fertility: Rice straw and manure can improve soil structure, increase the ability of water retention, and enrich soil microorganisms.
Reduced dependence on chemical fertilizers: By utilizing rice straw and manure, farmers can reduce their dependence on chemical fertilizers that often have a negative impact on soil health.
Increased crop yields: The SRI planting system that prioritizes the principle of efficient use of resources can increase the productivity of paddy rice in a sustainable manner.

Conclusion

The effect of the dose of fertilizer and the use of rice straw in the SRI planting system not only has an impact on the results of production, but also on the quality of the soil and the sustainability of agriculture itself. This is an important step to create more efficient and environmentally friendly agriculture in the midst of existing global challenges.

Recommendations

Based on the analysis of the impact of the use of rice straw and manure, the following recommendations are made:

Adopt the right rice straw processing method: Farmers are advised to adopt the right rice straw processing method, such as composting, to improve the quality of organic matter.
Counseling about the importance of utilizing the remaining harvest and manure: Counseling about the importance of utilizing the remaining harvest and manure as part of soil fertility management needs to be encouraged.
Promote sustainable agriculture practices: The use of rice straw and manure in the SRI planting system should be promoted as a sustainable agriculture practice that can increase crop yields while maintaining soil fertility and reducing dependence on chemical fertilizers.

By implementing these recommendations, farmers can increase crop yields while maintaining soil fertility and reducing dependence on chemical fertilizers. This is an important step to create more efficient and environmentally friendly agriculture in the midst of existing global challenges.

Q: What is the SRI (System Rice Intensification) planting system?

A: The SRI (System Rice Intensification) planting system is a method of growing rice that prioritizes the principle of efficient use of resources. It involves a series of land treatment activities to improve agricultural output, including proper soil processing, regular irrigation, selection of superior seeds, fertilizing, and eradicating pests and plant diseases.

Q: What is the role of rice straw in soil fertility?

A: Rice straw, as residual harvest, can improve the physical, chemical, and biological properties of the soil. It contains significant organic material content, with a composition of about 40% carbon (C), 0.6% nitrogen (N), 0.1% sulfur (S), and 1.5% silica (Si). The high carbon content in rice straw makes it a valuable source to increase soil fertility.

Q: What are the benefits of using rice straw and manure in the SRI planting system?

A: The benefits of using rice straw and manure in the SRI planting system include:

Increased soil fertility: Rice straw and manure can improve soil structure, increase the ability of water retention, and enrich soil microorganisms.
Reduced dependence on chemical fertilizers: By utilizing rice straw and manure, farmers can reduce their dependence on chemical fertilizers that often have a negative impact on soil health.
Increased crop yields: The SRI planting system that prioritizes the principle of efficient use of resources can increase the productivity of paddy rice in a sustainable manner.

Q: How can farmers adopt the right rice straw processing method?

A: Farmers can adopt the right rice straw processing method, such as composting, to improve the quality of organic matter. Composting involves breaking down organic matter into a nutrient-rich fertilizer that can be used to improve soil fertility.

Q: What is the importance of counseling about the importance of utilizing the remaining harvest and manure?

A: Counseling about the importance of utilizing the remaining harvest and manure as part of soil fertility management needs to be encouraged. This can help farmers understand the benefits of using rice straw and manure in the SRI planting system and adopt sustainable agriculture practices.

Q: How can the use of rice straw and manure in the SRI planting system be promoted as a sustainable agriculture practice?

A: The use of rice straw and manure in the SRI planting system can be promoted as a sustainable agriculture practice by:

Providing training and education: Providing training and education to farmers about the benefits of using rice straw and manure in the SRI planting system.
Encouraging the use of organic fertilizers: Encouraging the use of organic fertilizers, such as rice straw and manure, instead of chemical fertilizers.
Promoting sustainable agriculture practices: Promoting sustainable agriculture practices, such as the SRI planting system, that prioritize the principle of efficient use of resources.
