Abstract:
This study aims to analyze the growth of agroforestry plants and soil fertility at site conditions in the revegetation area of the Protected Forest Area Liang Anggang Banjarbaru. This research was conducted in the Liang Anggang Protected Forest Area, for 3 months. To analyze plant growth data and analysis of soil fertility using two methods, namely the analysis of plant growth using the method of determining the percentage of plant growth, while the analysis of soil fertility in site conditions based on physical and chemical of soil characteristics. The results showed that in the research location there were 9 types of plants, namely Petai, Belangiran, Mango, Longan, Rambutan, Soursop, Sawo, Jengkol and Citrus plants with a total plant of 377 individuals. There were 214 individuals at location 1 and there were 163 individuals at location 2. The highest percentage of plant life was petai at 63.69% and the lowest percentage was soursop plants at 6.25%. The highest plant height was jengkol at 177.83 cm, while the lowest was longan plant at 58.62 cm. The highest plant diameter was petai plants with a diameter of 2.1 cm while the lowest was longan plants with a diameter of only 1.0 cm. Soil fertility in the research site, the soil type has low fertility. The low fertility at the research location is due to limiting factors, namely the low content of P2O5, K2O and saturation of soil alkalis.
