Sago Values

Sago Shipment
Abstract Tropical peatland is a potential land resource for crop production to supply food and energy sources to increasing population. Although sago palm (Metroxylon sagu Rottb.) is a potential starch crop suited to this purpose, prefer control of groundwater level and fertilizer application should be done to maintain the high starch productivity. 
As it is also important to estimate the impact of sago palm cultivation on the environment from the view point of the sustainability, we investigated temporal changes in the chemical properties of drainage water and soil in a sago palm plantation in Indonesia.
Sago Flour (Tapioca Alternative)
Analysis of canal water from blocks with different palm ages during a 2-year period suggested small increases in Ca, K, and Mg concentrations with time (up to 8 years). No time-dependent changes were observed in the concentrations of other nutritional/toxic elements, although the larger concentration in groundwater below sago palm than in canal water was observed for fertilizer components including B, Ca, P, and Zn. Although large portions of Al, Fe, and Zn in canal water were interacted with dissolved organic C (DOC), the leaching of DOC did not vary with the development of palm growth. Contents of nutritional elements were generally similar among soils at 1, 3, and 5 m away from a palm, among soils at 0.1, 0.3, and 0.5 m depths, and between soils in sago palm block and adjacent secondary forest, regardless of plant age. Thus, the sago palm cultivation with fertilizer and groundwater level control did not induce notable deterioration of soil and water qualities.

Where To Buy Sago




Probably, most of the world's population to ask, which places a sago?, This question is not only one we get. Here we offer a sago producing area of ​​the county's largest archipelago Indonesia in Kepulauan Meranti Regency, this is where sago is planted, cultivated, developed in workshops and international transaction.
Among the county-owned product is as follows:
  1. corn starch
  2. cendol sago
  3. sago noodle
  4. sago plantation
  5. etc.

Analysis of soil samples



Part VI
Total contents of Ca, Cu, Fe, K, Mg, Na, and Zn in soil samples were determined with an ICP spectrometer (Liberty 220, Varian, USA) after digestion with HF and HNO3 in a microwave oven (Ethos 900, Milestone, Italy) according to Jones et al. (1991). Exchangeable cations were extracted from the 2002 samples with 1 mol l-1 ammonium acetate with pH regulated to 7 and determined with Liberty 220. pH and ash content of the soil samples collected from P8B19 and P3B3 and their adjacent forests were determined using a suspension of soil sample with distilled water mixed at 1:2.5 (w:v) and by the combustion method, respectively.

Collection of soil samples

Sago Root

According to Miyazaki et al. (personal communication), no roots were observed[1 m distance from 1- year-old sago palms, whereas 20 and 42% of total roots were distributed between 1 and 2 m distances from 3- and 5-year-old sago palms, respectively. They also observed that the root biomass of 1- to 5- year-old sago palms were concentrated within the surface 30 cm layer.

Analysis of water samples

Sago Starch Milk While Proceeded
Concentrations of Al, B, Ca, Cd, Cr, Cu, Fe, K, Mg, Mn, Mo, Na, Ni, P, Pb, and Zn in the water samples were measured with an inductively coupled plasma (ICP) spectrometer (IRIS, Thermo Jallel-Ash, USA). DOC concentration was determined with a total organic C analyzer (TOC-VCPH, Shimadzu, Japan). An aliquot of canal water samples collected from the seven sago palm cultivation blocks in July 2003 and January and July 2004 (20 ml) was fractionated on a column packed with 1.5 ml of anion exchange resin (Q Sepharose Fast Flow, Amersham Biosciences, Sweden) into adsorbed and non-adsorbed fractions. The concentrations of DOC and metallic elements in the non-adsorbed fraction were determined with TOC-VCPH and IRIS, and metallic elements distributed in the adsorbed and nonadsorbed fractions were regarded as organically bound and free cation forms, respectively (Kimura et al. 1998). Ultra-pure water that was passed through the resin under the same conditions as those for canal water samples was analyzed as blank. DOC was almost completely adsorbed to the resin (97 ± 4%). The amount of DOM-bound Ca could not be estimated due to the unexpectedly high recovery exceeding 100%.

PART III
Sago Trees (Improve The Best Claim)
The experiment was conducted at the National Timber and Forest Product sago palm plantation located in Tebing Tinggi Island, Riau Province, Indonesia (1_300N, 103_400E; Jong 2001). The mean annual maximum and minimum air temperatures in the 1996–2000 period, which were recorded at the nearest meteorological station, were 31.9 and 23.3_C, respectively. Annual precipitation was 1,700 mm with the maximum rainfall in December (222 mm) and minimum in July (79 mm). The plantation was initialized in 1996 on deep peat (Histosols) consisting of complex woody materials (100% peat). Tropical swamp forest that covered the plantation area was cleared ca 35 years ago, and thereafter the area was secondary forest. The map of the plantation is shown in Fig. 1. The southwestern border of the plantation is approximately 2.4 km from the coast. The plantation area is divided into 20 phases. One phase consists of 20 blocks, and each block has a land area of 0.5 km2 Fig. 1 Map of sago palm plantation in Tebing Tinggi, Indonesia.

PART II 
Peatland is characterized by the accumulation of large amounts of partially decomposed plant material, low pH, high groundwater level, and low nutrient content. Because of these characteristics, peatland is unfavorable for the use as cultivated fields. Nevertheless, to supply foods balanced with the increasing population, peatland occupying 30 million ha in Southeast Asia (Radjagukguk 1997) is a potential ground for crop production. As the high groundwater level interferes with the supply of oxygen into soil, drainage is generally required to facilitate respiration of plant roots in peatland reclaimed for agricultural use. However, peat materials may be decomposed and subsided quickly if groundwater level is lowered (Blodau 2002), which would accelerate nutrient loss from peatland and further lower plant productivity (Laiho et al. 1999). Sago palm (Metroxylon sagu Rottb.) is worthy of attention as a rare crop that can grow on tropical peat soil without drainage of groundwater and yields a great amount of starch, 164–180 kg per plant on a dry weight basis (Yamamoto et al. 2003).
