Introduction

Land evaluation is a crucial process in assessing land resources with a specific purpose, using methods that have been tested and proven effective. In Toba Regency, North Sumatra Province, land evaluation is essential to determine the suitability of land in supporting various types of forestry and versatile plants. This article aims to evaluate the ability and suitability of forestry and multipurpose tree species land in Toba Regency, North Sumatra Province, and provide recommendations for land management policies to support the sustainability of forestry and the economy of the local community.

Land Evaluation Methodology

Land evaluation is a process of assessing land resources with a specific purpose through the method that has been tested. In Toba Regency, North Sumatra Province, sampling was carried out using purposive sampling techniques to determine the suitability of land in supporting various types of forestry and versatile plants. The evaluation results show that the land capability class in Toba Regency is divided into several categories.

Land Capability Class

The land capability class in Toba Regency is divided into several categories, including:

Class I: Without inhibiting factors, including an area of 12,733.42 hectares or 44.27%.
Class II: With inhibiting factors in the form of drainage and slope.
Class IV: With a slope factor as an obstacle.
Class VI to VIII: Left naturally as a protected area due to inhibiting factors that are difficult to overcome.

Suitable Plant Species

Plants that are suitable for planting in this region include:

Pine (Pinus mercusii): A fast-growing tree species that is widely used for timber production.
Teak (Tectona grandis): A hardwood tree species that is highly valued for its durability and resistance to decay.
Mahogany (Swietenia mahagoni): A hardwood tree species that is highly valued for its beauty and durability.
Rubber (Hevea brasiliensis): A tree species that is widely used for rubber production.
Eucalyptus (Eucalyptus sp.): A fast-growing tree species that is widely used for timber production and pulpwood.
Multipurpose tree species: Including mango (Mangifera indica), soursop (Annona muricata), durian (Durio Zibethinus), avocado (Persea americana), and jackfruit (Artocarpus heterophyllus).

Land Suitability Class

The most appropriate land suitability class both actually and potential in Toba Regency is for wooden plants and multipurpose tree species. Among these plants, pine, mahogany, eucalyptus, mango, candlenut, jackfruit, and avocado are included in the marginal category (S3) and quite appropriate (S2). However, there are inhibiting factors related to nutritional retention with a percentage between 4.53% - 4.95% and C -organic content ranging from 1.03% - 4.66%.

Improvement of Land Suitability

Improvement of this land suitability can be done through the addition of organic fertilizer and burning residual ash, so that the potential of the land can be increased to be very appropriate (S1). This step will not only increase plant productivity but also contribute to sustainable management of natural resources.

Conclusion

With a good understanding of the characteristics of land and appropriate plant types, it is hoped that land management policies in Toba Regency can be optimized to support the sustainability of forestry and the economy of the local community. As a step ahead, collaboration between the government, researchers, and the community is needed to ensure effective implementation of the results of this land evaluation.

Recommendations

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

Land management policies: Should be optimized to support the sustainability of forestry and the economy of the local community.
Collaboration: Between the government, researchers, and the community is needed to ensure effective implementation of the results of this land evaluation.
Addition of organic fertilizer: Should be done to improve the land suitability class.
Burning residual ash: Should be done to increase the potential of the land.

By following these recommendations, it is hoped that the land management policies in Toba Regency can be optimized to support the sustainability of forestry and the economy of the local community.
