Description:
Tidal wetlands might be developed as productive farm lands. The tidal wetland in South Kalimantan, especially in Barito Kuala District has evolved into a variety of farming systems including rice fields, orange farm lands, and fish pond aqua-culture. Productivity of tidal wetland agroecosystems could be increased through a system approach that is integration of some farming sub-systems, so that flows of materials and energy run effectively and efficiently. The system will meet its needs of materials and energy indepedently. Increased productivity of agroecosystems on tidal wetlands can be done through a systems approach, the integration of several sub-systems of farming, the amount and type of water and adjusted to the characteristics of the soil, so that the flow of materials and energy (both products and by products) runs efficiently and effectively. In other words, the system will meet its energy needs and the materials independently. How to design a model of tidal marsh land agroecosystems based on material and energy independence is necessary to study the potential of the product and its by products from multiple subsystems original farm there (existing farming), water balance and nutrients, as well as in situ resource that has the potential to be used as sources of materials and energy in tidal swamp land management for agricultural purposes. Materials and energy indicators observed included major nutrients N, P, and K. Agro-ecosystem model development refers to the Input-Output approach on certain systems at the farm-scale farmers and agro-ecosystem scale are limited by the existing river system (landscape scale).
