Experimental research will be executed on farm of rice field sample in BPP Palaguna at Wajo Regency. Obstetrical nutrients Analysis of crop and soil will be done in soil Fertility Laboratory, soil sciences department of Faperta Unhas. This Research aim to analyze the ability of nutrients absorption of soy and maize with the mulch application on rice field rainfed. Research will be done/conducted by using Factorial Device in Group ( RDG). First Factor that is crop type with three treatment level that is L1 = Soy; L2 = Maize; and L3 = Maize + Soy. Second Factor is with mulch (M1) and without mulch (M0). Every treatment unit repeated by 3 times, so there are 18 plot, added a plot which is not cultivated as control for the perception of dynamics of Nitrogen (N) and Phosphorous (P) without palawija cultivation. Reason of the crop election for example because both types of the crop have their own system of root and different morphology characteristic which their possibility will influence the ability of conservation N. Result of analysis indicate that ability of absorption of N and P of maize and soy is better with the mulch application on rice field rainfed

Soil forming process can influence soil stability, especially on a sloping area, which is currently related to landslides. This research aims to study mineral content in the soil as an indicator to evaluate soil stability in slope area. Soil texture analyzed with hydrometer and soil mineral analyzed with Kerr method. Soil parent rock comes from Tpbv (Tertiary Pliocene Baturape Volcanic) Formation that consists of lava, breccia, tuff, and conglomerate. Soil texture in A horizon dominated with silty clay loam and in B horizon with silty clay. Clay content in A horizon to B horizon increase ranges from 2-6%. Soils mineral have been weathering on the physical and chemical, which caused cracking on minerals lattice and formed clay minerals inside it. The presence of clay minerals between soil mineral particles can cause mutual repulsion force and cause friction particles that triggering the movement of particles in a small scale when soil saturated by water and triggers soil movement (landslide).

In Indonesia, there is not much use of potassium fertilizer for plants. Generally, farmers are more familiar with nitrogen and phosphorus fertilizers than potassium. This is caused potassium is expensive and hard to find, so there should be another alternative for easily and economic potassium fertilizer. This study aims to analyze the effect of organic liquid fertilizer produced from banana stem and coconut fiber to increase Potassium in soil and maize growth on ex-cassava cultivation land in Moncongloe Bulu Village, Moncongloe District, Maros Regency. The study used randomized block design within two factors and replied for three times. The first factor is coconut liquid fertilizer with 4 levels; SK1 (50 ml/pot), SK2 (100 ml/pot), SK3 (150 ml/pot) and SK4 (200 ml/pot). The second factor is banana liquid fertilizer with 4 levels; BP1 (25ml/pot), BP2 (50ml/pot), BP3 (75ml/pot) and BP4 (100ml/pot), so there are 27 total of treatment units. The results showed that coconut liquid fertilizer significantly affected plant height, number of leaves, dry matter weight, dry root weight, matter weight, root weight, organic carbon, cation exchanged capacity, percentage Potassium of maize, and gained the highest average of Pottassium increasing in soil. Nevertheless, it has not significant effect to soil pH.

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.

Land potential can be assessed from biophysical land suitability including soil characteristics, climate, and land management. This study aims to determine the potential of paddy fields in Duampanua Sub-District, Pinrang District for irrigated paddy field based on the land biophysical characteristics. The method was qualitative and quantitative approaches. Field surveys use purposive sampling method with 3 object observation. The land suitability class evaluation uses a simple limiting factor approach according to FAO (1976). To support the analysis of rice production data, 30 farmers were interviewed in 3 (three) observation units. The results showed the average rainfall of 2,780.2 mm/year with 9 wet months and 3 dry months categorized as type B2 (Oldeman). The results of soil samples analysis showed the characteristics of the soil with a silty clay texture, silty clay loam and clay; bulk density ranges from 1.36-1.66 g/cm3; cation exchange capacity ranges from 49.64 - 79.75 cmol/kg clay; soil pH ranges from 5.26-5.97; base saturation ranges from 36% - 46.4%; and C-organic ranges from 1.34% - 1.38%. The most dominant types of minerals are orthoclase, biotite, pyroxene, augite, opaque and clay with the symptoms of micropedological concretions and nodules. The land suitability class in the three land units for irrigated paddy rice is classified as S2nr (quite suitability in accordance with the limiting factors for nutrient retention including: base saturation, pH, and C-organic). The average productivity in land units I is 5.1 ton/ha, land unit II is 4.5 ton/ha, and in land units III 5.26 ton/ha.

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%).
