Abstract

Acacia mangium Willd. classified as plants that require nutrients are complete and available or Nutrient demanding crop, althought for grow and evolve requires a lot of nutrients that one of them is the phosphorus element. Phosphorusis needed absorption of nutrientsb by increasing the number of nodules on the roots so as to increase plant growth. The fertilization is o.0ne way that can be done to fulfill the availability of soil nutrients that plants need. The purpose of this research is to determine the effect of phosphorus fertilizer application on acacia seedlings in topsoil medium, determine the best dose to the growth of seedlings of acacia and check the availability of phosphorus in the soil at this seedling. This research uses a completely randomize design method which consist of 4 treatments and 10 replications. T0 = without phosphorus fertilizer; T1 = 20 g/polybag ; T2= 25 g/polybag ; T3 = 30 g/polybag ;.The resultsof this research indicates thatthe phosphorus fertilizer with 25 g / polybag dose on top soil medium is the best treatment in the parameter of observations, the high increasing (9.36 cm), the diameter increasing (1.19 mm)for seedling Acacia mangium Willd. in topsoil medium. Giving  of phosphorus fertilizer can increase soil pH (4.56), P-bray (527.66 mg / kg) and P-total (7000.1 mg / kg) the availability increasing of phosphorus in the soil for growth seedlings Acacia mangium Willd.

Abstract

The increased number of vehicles are getting bigger every year, including in Pekanbaru. One of the air pollution sources come from vehicle. The exhaust from vehicle contains harmful heavy metals, for example is the lead. Tuanku Tambusai Street (Nangka Street) is one of the crowded streets in Pekanbaru which have a quite large heavy metals that emitted into the air. Lead is harmful to human health and the environment, so shade plants needs to be planted as bio-indicators. However, not all plants have the same ability to absorb the lead. This study aims to determine the amount of lead content in shade plants on Tuanku Tambusai street, in Pekanbaru city and to know the type of shade plants and canopy strata that most absorb to the lead. This study uses a Wet Ashing Method for the destruction the sample, then it is analyzed using Atomic Absorption Spectrophotometer (AAS). The results shows that the leaf Polyalthia longifolia Bent. & Hook. F. is 1.88 µg/g higher than Pterocarpus indicus Willd. 1.57 µg/g and Swietenia macrophylla 1.16 µg/g. Lead content in the middle of the canopy strata (1.72 µg/g) is higher than the content of lead in the bottom of the canopy strata (1.52 µg/g) and the upper canopy strata (1.38 µg/g). Keywords: lead, shade plants, Polyalthia longifolia, Pterocarpus indicus, Swietenia macrophylla
