Pb and Cd are two types of heavy metal that has been widely contaminates agricultural land. Pollution on agricultural land led to a decrease in productivity, disruption of the ecological balance and impaired human health. The research aims to identify and detect the content of heavy metals Cd and Pb in the soil and measure the effectiveness of the arbuscular mycorrhizal veskular withstand heavy metals in lettuce plants. Soil samples were collected in the Village Sudiang Makassar City using stratified sampling and purposive sampling methods. Sampling points are distinguished based on the distance from the highway, which is 15 meters and 30 meters. Analysis of heavy metal content in soil carried Soil Laboratory BPTP Maros. The study based on a randomized block design in a factorial 2 factors. The first factor was soil sampling and the second factor was the provision of mycorrhizae. Based on the survey results revealed that the content of Pb and Cd in soil belt of northern South Sulawesi has passed the threshold. Due to the reduced content of Pb and Cd after treatment arbuscular mycorrhizal fungi but the decline is not significant compared with no treatment mycorrhizae. The content of Cd and Pb in plants of lettuce grown in the various media and the addition of CAM treatments above the threshold concentration safe for consumption.

Various ways have been made to increase the productivity of rice plants as a source of staple food of Indonesian society. One ofthem is the addition of nutrients in the soil (fertilization). Currently, the innovation use of seaweed as fertilizer is widely used in several countries in the world, because seaweed contains phosphorus, potassium, and some other micro elements. This study aimed to analyze the use of various types of waste seaweed to improve the productivity of paddy rice on the ground Vertisol. The study lasted from December 2014 through Sept. 2015, at Greenhouse, Teaching Farm, Faculty of Agriculture, University of Hasanuddin Makassar. The research method is a randomized block design consisting of eight treatments and six replications (48 pot experiment). Each treatment is C0 (control), C1 (fertilizer N 300 kg / ha, P 100 kg / ha and K 100 kg / ha), G1 (Gracilaria 10 g / pot), G2 (Gracilaria 100 g / pot), S1 (Sargassum 10 g / pot), S2 (Sargassum 100 g / pot), K1 (Kappaphycus 10 g / pot), and K2 (Kappaphycus 100 g / pot). The addition of Sargassum seaweed fertilizer waste 100 g / pot and Kappaphycus dose of 100 g / pot can increase K-dd, Na- dd, base saturation, increase the value of N, P, K, and Ca-dd, but administration with concentrations of 100 g / no maximum pot for rice crop production by causing toxicity in plants. The addition of seaweed fertilizer waste treatment Gracilaria 100 g / pot is effective in improving Vertisol soil chemical properties and can provide maximum results for the productivity of rice plants

Agricultural wastes able to provide profit value if utilized properly for example made into organic fertilizer. Organic fertilizer production requires microbial decomposers to help the decomposition process. This research aims to isolate and identify the characteristics of microbial decomposers found in straw compost, soil sediment from tempe lake and soil from exfarm. In this research, conducted microbial isolation. Microbial exploration of compost material, soil organic matter and soil deposition material is mixed with physiological solution then grown on PDA, further purification of the unwanted microbes. In this study only used the media to grow the asparagine fungus to see the growth of macroscopic and microscopic fungi. The results showed that there are seven isolates of the fungus from different material extraction. The extracted compost material to produce two fungi are Aspergillus sp. and Penicillium sp., Tempe lake sediment soil shows three types of fungi with Aspergillus Sp. and two types Zygomisota, while soil from Exfarm also shows two types of fungi are Aspergillus sp. and Penicillium sp. The growth rate of each different fungal isolates based sources although of the same type

Soil minerals are very important for plants and can be use to assess the potential of soil fertility. This study aims to assess the potential of soil fertility based on mineral identification in Banggae and Eastern Banggae Subdistrict, Majene District, West Sulawesi Province. The method used in this research is descriptive quantitative, by identifying the minerals in the parent material and soil from thin section using polarizing microscope, quantification method for minerals percentage, and classified of nutrient potential with percentage of mineral content reduced by the percentage content of the quartz. The results showed that the dominant mineral found in the parent material and soil are pyroxene, plagioclase, hornblende, biotite, calcite, quartz and opaque, but the size of mineral are smaller than in the parent material. Potential of nutrients generated in the form of weatherable minerals are biotite, calcite, plagioclase, hornblende and pyroxene containing elements such as Mg, Ca, K, Fe and Na. Potential soil fertility in parent material currently on the moderate criteria (48% to 70%), while on the soil with middle criteria (48% to 70%) in P1L1, P2L1, P4L1, P8L1, P9L1, P10L1, P11L1 and P11L2 and good criteria (73% to 79%) in P3L1, P3L2, P4L2, P5L1, P5L2, P6L1, P7L1 and P9L2. Potential nutrient contained in the mineral is not available for plants, because it has not been supported by external factors such as the low availability of water. This is due to the climate condition especially rainfall in research area is in the range of 949.0 to 2557.1 mm/year with an average annual rainfall of 1608.0 mm/year.

The protection of agricultural land is very important to be studied scientifically considering the rapid growth of the population so that the possibility of land use conflict is very high. The main purpose of this research is to identify and inventory agricultural land of food especially existing rice-paddy fields to find zonasi agricultural land for sustainable foodcrops (ALSF) and agricultural reserved land for sustainable foodcrops (ARLSF)) with the level of threat from the transfer function in Gowa Regency area of hinterland Mamminasata, South Sulawesi. This study used a multiple criteria decision making approach with purpose mapping function of ALSF and ARLSF. The generic attributes, from: the biophysical aspects of the land (altitude, sizes of soil cracking, length of rice-field in slope landscape unit, proportion of paddy field area, top soil thickness), and socio-economic aspects (population density, population growth rate, demand for paddy field, productivity of paddy fields, equilibrium of paddy field), and policy aspects (local regulations status, detailed spatial plan status, type of irrigation networks). While the scenario of zonation of ALSF and ARLSF is used the criteria of distance from the provincial capital (Makassar) and the district capital (Sombaopu), the status of the rice-paddy field equilibrium and the trend pattern of percentage of space requirement. The results of the research shows that the existing position of paddy field is identified as ALSF and ARLSF zonation currently 24,210 Ha. The level of vulnerability of land conversion, which is in a "safe" position of 15,407 Ha (63.64%), and "threatened" of 8,803 Ha (36.36%). The prediction of productivity potential is related to the area of land that can be managed optimally in the vulnerable time up to the year 2020 covering 19,499 Ha (80.54%), and subsequently, by 2040 the area will shrink to only 10,173 Ha (42.02%).
