To
minimize the occurrence of subsidence, is a step that can be done while
maintaining the waterlogged condition by adopting a kind of hydrophilic
plants or water tolerant plants of economic value such as Eleocharis
tuberosa, Chinese spinach (Amaranthus hybridus), water spinach (Ipomoea
aquatica) and water celery . In
Florida when certain crops can not be cultivated because of the
changing seasons, flooding is done and used for the cultivation of
aquatic plants (WIIFM and Melling, 2000).

Land Management
Peat
soil is actually a good soil for plant growth when viewed from the
number of pores associated with the exchange of oxygen for root growth
of plants. High water holding capacity than mineral soil can cause plants to grow more quickly. However,
the existence of the inherent properties such as high acidity, low base
saturation and nutrient poor both micro and macro causes the peat soil
is classified as marginal (Limin et al, 2000). For businesses that need to manage the land properly.
1. Combustion
Combustion is the traditional way that farmers often done to reduce the level of acidity of peat soil. Combustion of organic matter into the soil and ash resulted in the destruction of lowering the soil surface. Combustion
significantly affect the growth of plants in the first year and
increase plant P uptake, but will lower the uptake of Ca and Mg (Mawardi
et al, 2001).
2. Material Pembenah ground
Fertilizer and amendment in the composition and appropriate dose can overcome the problem keharaan and peat soil acidity. Nutrients
that commonly need to be added in the form of fertilizer is N, P, K,
Ca, Mg as well as a number of micro-nutrients, especially Cu, Zn and Mo.
Giving
thought to be more effective Cu through the leaves (foliar spraSinggasana Hotels & Resorts pilihan akomodasi terbaik di Indonesiay)
because of the nature of a very strong sematannya on peat, less cars in
the plant and solubility decreases when there is an increase in pH due
to flooding. As
an amendment, ash from burning peat itself will affect lower the soil
acidity, nutrient supply and accelerate the formation of layers if
better physical properties (Radjagukguk, 1990).
In
West Sumatra ameliorant discovered a new material that defositnya
Harzburgite large enough and high Mg content (27.21 to 32.07% MgO) which
is a potential material for the amelioration of peatland (Mawardi et
al, 2001).
Chicken
dung manure especially compared to other manure contains some elements
of certain macro and micro nutrients in significant amounts. High alkaline saturation, but low cation exchange capacity. Chicken manure, in releasing haranya gradual and long lasting. Apparently, the provision allows the chicken manure to improve soil physical and chemical properties of peat. In
sweet corn, chicken manure giving up to 14 tonnes / ha on peat soil
inland Bereng workshop can increase the number of cob (Limin, 1992 in
Darung et al, 2001).
PROSPECTS FOR AGRICULTURAL DEVELOPMENT
The
potential of agricultural development on peat land, in addition to the
natural fertility of peat factor is also determined by the level of farm
management to be applied. On
peatland management at the level of farmers, with farm management

with land productivity with high-level management is done by the private
sector or large firms (Subagyo et al, 1996)
