Abstract

Acid Sulphate Soil is a kind of soil with high pyrite (FeS2) content. Miss management in land reclamation of acid sulphate soil will cause pyrite oxidation that made the soil becomes very acid. Pyrite oxidation on acid sulphate soil will produce iron oxides such as goethite (α-FeOOH) and hematite (α-Fe2O3). Goethite and hematite have ability to bind the anions and cations in the soilsuch as phosphate which produces a complex surface binuclear with model of Fe-OP(O2)-O-Fe. On acid sulphate land because of its association with soil Fe and its solubility alteration during reduction and oxidation processes of land, P is a limiting factor. More iron oxide in the soil, more P is retentioned. Each m.mol Fe in soil will bind P as much as 0,17 m.mol P.

Abstract

Swampy lands in Indonesia are covering a very large area which are distributed in three main islands i.e. Sumatra, Kalimantan, and Papua. The total areas of swampy lands are 33.4 millions ha, that consist of tidal land areas covering 20 millions ha more or less, and about 13.4 millions ha of non tidal lands. To develop swampy land area need good planning with proper technological application, especially in soil and water management. The objective of opening swampy land areas is to overcome the decreasing of rice productivity of rice field in Java. This is due to landuse conversion to another function, such as office building, highway, roads, and manufactures. PLG areas consist of four blocks, namely Block A, B, C, and D which covers 268,000 ha, 156,000 ha, 570,000 ha, and 138,000 ha, respectivelly. The strategy for developing these areas are: 1) To make master plan of PLG areas, 2) The peat land that has a thickness more than 3 meters utilized for conservation areas, 3) The peat land with less than 3meters thickness will be utilized for developing agriculture, fishery and forestry, 4) Protection areas for developing biodivercity. If those strategies are being conducted, thus the rehabilitation and revitalization of this area will be easily executed. According to the research result conducted by Agency of Agricultural Research and Development during the period of 1997-2000 in these areas, it is indicated that the soils are very potential for food crops, horticultures, and fruits. The limiting factors of these areas are pest, diseases, and flooding at the peak of rainy season. These areas are very potential for agribusiness such as food crops, vegetable crops, fruits, and estate crops, if macro water management network can be functioned normally and limiting factors can be controlled.

Abstract

Indonesia which covers 188.2 million ha of land area has great opportunities for soybean expansion. Until now, domestic need for soybean is still complied from import. Soybean is one of the strategic commodities for food and industrial needs, which in 2008 became a national issue because of the scarcity in the market. Therefore, the Department of Agriculture launched a selfsufficiency policy on soybeans targetted in the year 2014 through breakthrough efforts. To support the target, suitable land for soybean has been identified in 17 provinces. The results showed that land suitable for soybeans is around 16.7 million ha, scatteredin various location, namely 4.9 million ha in wetland area, 1.7 million ha in dry land area, 1.7 million ha in plantation area, 2.9 million ha in mix garden area, and 5.5 million ha in grass land area. If 30% of the assumed land suitable for soybeans in ricefield and upland can be utilized, these can produce 2.4 million tons of soybeans with the assumption that the average productivity levels is 1.2 tonnes/ha and once a year planting to maintain the balance of others commodity production. By utilizing 2 million ha of ricefield and upland, soybean self-sufficiency can be achieved in 2015. The development and extensification of soybean planting area should consider land suitability level. Area selection which historically has became soybean production center in 1990 is also has to take into account as well as farmer’s habit in soybean farming system. To accelerate the soybean self sufficiency, the improvement of human resources must be supported in form of assisting, motivation, extention, training, and plot dmeonstration, in order to gain optimal land productivity and technological application. In addition, the government supports are needed for the provision ofproduction facilities, capital, building the marketing chain, as well as conditions to create reasonable prices so that there isincentive for communities to develop soybeans.

Abstract

Indonesia has been able to reach self sufficiency for rice, but the problem is decreasing farmer economic value exchange. For that reason besides pursuing increase land productivity and agriculture commodities development, the improvement farmer income must be done. Daerah Istimewa Yogyakarta Province has ± 0,319 million ha within land typology from mountainous vulcanize until sand shore. The problem is narrow land tenure, so that to increase farmer income the development of agriculture commodity with high economics value should be executed based on land carrying capacity. High diversity of land typology with good irrigation network and farm road infrastructure make DI Yogyakarta Province potential to be developed as agriculture seed centre and off season commodity planting. The minerals deposit of volcanous Merapi mountain and marine can increase quality ofagricultural product which good for health, therefore it is potential for development of functional food and improvement livestock reproduction for calf production. Through agricultural product that has high economics value, farmer income and public prosperity are expected to increased.

Abstract

Land capability classification has been used for land evaluation for various purposes in many countries in the world. Since developed by the United States Department of Agriculture as a part of the programme to control soil erosion, the land capability classification has been further developed by a number of authors in many countries to suit their requirements. Of the numerous land capability classification have been published, fourteen are selected to be reviewed. The results shows that the aims of the various land capability classification schemes are generally similar: to evolve methodology whereby land may be evaluated for a particular land use purposes. Most of the methodologies were designed mainly for evaluating the capability of land for agriculture, either in narrow (specific) or in broad terms (including forestry, pasture, etc). Three methods of evaluation of data can be identified: Firstly, descriptive methods whereby capability classes or other categories are descriptive solely in words. Secondly, rating, grading or indexing system whereby each attribute is assigned a rate, grade or index and the capability class or other category is defined in terms of the sum of the weighted scores. Thirdly, quantitative methods whereby the relationships between variables are defined in terms of an equation used to obtain a score or index which defines the capability class or other categories. The capability methods also vary both as hierarchical systems and in terms of the number of categories used. They are also vary in terms of scale, and some do not even specify the scales used. Although substantial differences are found among the methodologies in terms of their purposes and detailed procedures, these are all broadly similar in terms of the general approach and activities involved.

Abstract

Dryland areas in Indonesia which have not yet managed intensively as an agriculture land cover 12.90 million ha. These areas are not well managed due to low growing index, especially in Java Island. The lack and the weakness of dryland management in Indonesia causing degradation of soil function and influencing the effort to raise people welfare. Entering the third Millenium era, the paradigm and conception of natural resources management, including reformation of dryland management are needed to be renewed. Based on bio-physic factors, moderate to high potential dryland cover 5.09 ha and low potential dryland cover 7.81 ha. Environmental physical constraint can be overcome both by short and long program in order to support food-self sufficiency stabilization. Short program is coordinated efforts to build productive dryland agriculture using technology and new innovation through integrated plant and land resources management. Long program is the continuation and extension of short program, and other effort to enhance food productivity through optimizing dryland resources utilization technologies (soil erosion control, smallponds establishment, water distribution management, and seeding system) and organizational. Food production of 11.34 x 106 t dryland rice and 6.91 x 106 t grain per year can be gained through the reformation of dryland management. Reformation of dryland management is absolutely needed to support and stabilize food-self sufficiency in Indonesia, in order to release our dependency on food import from abroad.

Abstract

Developments in Indonesia has raised several positif impact for most people due to gaining the new opportunity jobs. However, these positive opportunity often raised negative impact, especially on land resources and the environment, and people surrounding. Development industries on productive agriculture land have decreased agricultural areas, pollution of soil, water bodies/rivers, and cheerfulness and health of people and other humanlife. Mine activities also caused negative impact such asdegradation of land resources and environment, and pollution due to the application of chemical matterial on sevaration of mine products. Land clearing for infrastructures construction (roads, buildings, bridges), and agricultural practices had caused land degradation and the environment, and pollution as well. The disturbance of natural resources and environmental imbalance caused the deterioration of soil productivity, and the quality of agricultural yield due to chemical contamination on soil, rivers/water bodies, and crops. These condition has to consider necessary effort on the agricultural and environmental management more precised,directed, and accurated. Therefore, identification and characterization of sources of degradation and pollution, and analyses on issues raised in the field to form strategic effort on agricultural environmental management. The deterioration of soil productivity could be managed by applying soil conservation and land rehabilitation techniques through integrated management of related governments, institutions, and farmers/people. The pollution on soil and plant need quality standard criterium for heavy metals, and the values could be determined and difined for Indonesia condition. Critical levels of heavy metals in the soil could be used as a guide for implementation of law imporcement. Industrial waste which is polluted rivers and water bodies could be easly predicted, due tospesific industry resulted chemical contents of liquid waste similar with content of raw materials. Inappropiate land management could accelerate increasing green house gases in the atmosphere, and would be caused global warming as well. Excessive carbondioxide emission could be controlled by sequistrated CO2 through revegetation and rehabilitation of degraded land. Methane (CH4) and nitrousoxide (N2O) emission from lowland rice could be controlled by reduction its planting areas and substitute by non rice commodites, appropiate and better water management, and slow release nitrogen fertilizer application.

Abstract

Agricultural production is one of the most weather sensitive human activities that depend on daily atmospheric conditions. This review attempts to describe the meteorological data for crop requirements, some techniques of climate prediction and its use for crop simulations. Despite the rapid progress achieved in forecasting technology lately, further works are necessary for the real application. The amount and distribution of the rainfall in the coming season is necessary for planning crop cultivation particularly when climate anomaly arises. In agriculture the efforts to bridge the gap, climate forecasting results are the main input in crop simulation, especially for water and agro-climate management and cropping calendar.

Abstract

Indonesia is in the region "wet tropical megabiodiversity" it would need to complete the system  for agricultural land suitability evaluation in accordance with real conditions, thus increasing the value-added resources optimally and sustainable and accountable production investment. Soil organisms as a component of production support can act as an agent of energy and nutrient cycling in the soil, improving soil physical properties, and controlling pests and disease. For that soil, biological parameters that need to be considered in evaluating the suitability of land that already exist include: N-fixing or P-solubilizing bacteria groups that live symbiosis and free-living, the fungi solubilizing P and soil organic matter decomposition groups, BGA fixing and free-living N symbiotic groups, fauna groups are able to conserve soil organic matter and improve soil physical properties. Important steps that need to be done in the evaluation of land cover inventory of soil biological populations and its role on the growth of crops, and evaluate the suitability of the soil biological parameters of the functional value of commodity options.
