Introduction

The fertility of dry land agricultural soil is a crucial factor in determining the productivity of agricultural land. In the Bonatua Lunasi District, Toba Samosir Regency, the potential for fertility of dry land agricultural soil has been a topic of interest for researchers and agricultural experts. This study aims to reveal the potential for fertility of dry land agricultural soil in Bonatua Lunasi District, Toba Samosir Regency, and to identify the challenges and efforts to improve soil fertility in this region.

Methodology

This study was conducted in July to August 2018, using a survey method with stratified random sampling soil sampling. Eight samples of dry land in the region were analyzed to determine the level of fertility, with parameters including soil texture, specific gravity, pH, cation exchange capacity, base cations content (Ca, Mg, Na, and K), P-Available, C-Organic, and the amount of soil microorganisms.

Results

The results of this study showed that the land in Bonatua District was dominated by the sand fraction, resulting in an average soil specific gravity above 1 g/cm3, which indicates a bad soil structure. Soil conditions are also classified as very sour with low pH, thus inhibiting the absorption of nutrients by plants. In addition, the content of P-available, C-organic, alkaline cations, and the number of soil microorganisms is relatively low, indicating a very low level of fertility. This condition is found in all regions of Bonatua Lunasi District, including villages such as Harungguan, Lumban Lobu, Lumban Sangkalan, Naga Timbul Naga, Dragon Timbul Timur, Pardolok Lumban Lobu, Partoruan Lumban Lobu, Sanggahon, Sihiong, Silamosik II, Silombu, and Sinar Sabungan.

Challenges and Efforts to Increase Soil Fertility

The results of this study revealed several main challenges in increasing soil fertility in Bonatua Lunasi District.

Limited Water

Dry land in this region is vulnerable to drought, so that the water supply for plants is limited. This is a major obstacle for plant growth, as plants require adequate water to absorb nutrients and grow.

Low Nutritional Content

Low levels of soil fertility, especially the content of P-available and C-organic, are the main obstacles for plant growth. P-available is essential for plant growth, as it provides phosphorus, which is necessary for plant development. C-organic, on the other hand, is essential for maintaining soil structure and fertility.

Poor Soil Structure

The dominance of sand fractions results in poor soil structure, so the ability to hold water and nutrients becomes low. This is a major challenge for plant growth, as plants require adequate water and nutrients to grow.

Limited Resources

Access to the right agricultural fertilizer and technology is still limited in this region. This is a major obstacle for farmers, as they require access to the right resources to improve soil fertility and increase agricultural productivity.

Efforts to Overcome Challenges

To overcome these challenges, efforts are needed to increase soil fertility in an integrated manner.

Water Management

The application of efficient irrigation systems, such as making drill wells, small dams, and drops of irrigation systems, can help overcome the problem of water limitations.

Increased Nutritional Content

Provision of organic fertilizer, both from manure and compost, can increase C-organic content and improve soil structure. The application of plant rotation systems and planting ground cover plants can also help maintain soil fertility.

Soil Processing

Application of appropriate soil treatment systems, such as processing soil without processing, can help maintain the structure of the soil and improve the ability of the soil to hold water.

Increasing Technology Access

The government and related institutions need to provide training and counseling on the right plant cultivation techniques, as well as providing access to fertilizers and pesticides that are environmentally friendly.

Conclusion

This study shows that soil fertility in Bonatua Lunasi District is classified as very low, becoming a major obstacle for agricultural development in this region. To improve agricultural output and community welfare, integrated efforts are needed in increasing soil fertility. Increasing access to technology, resources, and knowledge, as well as the implementation of appropriate crop cultivation techniques, is expected to encourage increased agricultural productivity in this region.

Recommendations

Based on the findings of this study, the following recommendations are made:

The government and related institutions should provide training and counseling on the right plant cultivation techniques, as well as providing access to fertilizers and pesticides that are environmentally friendly.
Farmers should adopt efficient irrigation systems, such as making drill wells, small dams, and drops of irrigation systems, to overcome the problem of water limitations.
Farmers should provide organic fertilizer, both from manure and compost, to increase C-organic content and improve soil structure.
Farmers should adopt plant rotation systems and planting ground cover plants to maintain soil fertility.
The government and related institutions should provide access to the right agricultural fertilizer and technology to farmers.

By implementing these recommendations, it is expected that soil fertility in Bonatua Lunasi District will improve, and agricultural productivity will increase, leading to improved community welfare.
