“…The available P concentrations in RS- and GN-treated soils did not increase after 22 years of annual application, whereas those in DP and CT soils decreased compared to the earlier period (year 7) ( Figure 3 d). Sukitprapanon et al. (2019) reported that P can be adsorbed by organic matter and fixed by Fe and Al (hydro)oxides in soil under acidic conditions.…”

“…Applications of organic residues to soils have been shown to increase soil fertility in general, including increasing soil aggregation, soil organic carbon, soil pH, and soil nutrients. In addition, the application of organic materials to soils decreases the mobilization of potentially toxic elements (e.g., Al, As, heavy metals, and rare-earth elements) ( Samahadthai et al., 2010 ; Li et al., 2019 ; Yusiharni and Gilkes, 2012 ; Sukitprapanon et al., 2019 ). Plant residues contain variable levels of nutrients depending on plant species, plant part, and plant age ( Palm et al., 2001 ; Vityakon, 2001 ; Yusiharni and Gilkes, 2012 ).…”

Intensive use of sandy soils for agriculture leads to significant land degradation. The application of locally available organic residues can improve soil fertility, particularly in the context of organic farming practices. This research examined nutrient concentrations in locally available organic residues with different biochemical compositions/qualities and investigated the effects of long-term application of these residues on available nutrients, such as P, K, Ca, Mg, Fe, Mn, and Zn, as well as on total organic carbon (TOC) accumulation in tropical sandy soil. A field experiment was conducted in Northeast Thailand, where four local organic residues, groundnut stover (GN), tamarind leaf litter (TM), dipterocarp leaf litter (DP), and rice straw (RS), had been applied annually for 22 years. These organic residues were acidic (pH 3.7–5.8). The macronutrients N, P, and K were present at elevated levels in the high-quality organic residue GN, whereas medium-quality TM and low-quality RS and DP were dominated by the macronutrients Ca and Mg and the micronutrients Fe, Mn, and Zn. The incorporation of organic residues, particularly TM, resulted in the accumulation of TOC. Furthermore, long-term incorporation of TM increased soil pH, whereas incorporation of GN, DP, and RS did not. The higher increase in the soil pH of TM soil is likely because TM contains higher levels of ash alkalinity compared to other residues. The application of medium-quality TM increased the soil available P, Ca, and Mg, whereas low-quality organic residue RS and DP applications increased the concentrations of soil micronutrients (e.g., Mn and Zn). However, long-term applications of local organic residues did not increase available K in the sandy soil.

“…The results showed that low soil pH had an impact on reducing maize yields by 11-37% [15], and rice yields from 14.52-28.97% [16]. Rice productivity in acid soils can be increased, among others, through the application of lime [17], and the application of Ground Magnesium Limestone (GML) in combination with a biofertilizer [13].…”

The existing land characteristics and inappropriate management during intensive agricultural practice on upland, swampland, and paddy field are the factors that causing land productivity to be low and decreasing. Alternative efforts to increase the land, rice, and maize productivities could be carried out through the implementation of Site- Specific Nutrient Management technology based on the RAE parameter. This paper presents thoughts on the opportunities for refocusing RAE- based research on agricultural cultivation technology, and research results that have been done.The research of rice and maize with RAE in the upland and paddy field has resulted in a location-specific cultivation technology package. The technologies that have been produced are single NPK inorganic fertilizer package, the combination of single NPK- compound NPK inorganic fertilizers, the combination of single NPK inorganic fertilizer-organic fertilizer, and combination of single NPK inorganic fertilizer-biofertilizer. By using RAE value, these researches have shown a more effective technology package in comparison with standard technology. The technology devices for determining standard fertilization needed to support the research with RAE parameter as the basis are available. The said devices are Upland, Swampland, and Paddy Soil Test Kit. Refocusing research of location-specific fertilization that explicitly using RAE parameter is relevant to promote sustainable agriculture.

“…On the other hand, Increasing levels of aluminum and iron in the soil solution also cause a decrease in the quality of water in the canals, soil pH and water pH dropping to a range of 2.3-3. Then the water channeled should be fluch out and replaced by freshwater from the rain or tidewater (Sukitprapanon et al 2019).…”

The primary key to successful agricultural cultivation is maintaining the groundwater level to fulfill crop water requirements, particularly during the dry season. Field study was conducted in Tidal reclamation area of section 25 at Sugihan Kanan, Bandar Jaya Village, Air Sugihan, Ogan Komering Ilir District of South Sumatra. The DRAINMOD computer model was used to simulate water levels in dry and wet climatic conditions. The principal measured parameters are soil hydraulic conductivity and drain spacing, as well as daily rainfall data. The simulation results showed that the research area belongs to the rainfed type, and the main objective of water management is to retain water and determine some efforts to increase the groundwater level through pump irrigation in the dry season. The application of pump irrigation was applied to the plant entering the generative phase. The pump irrigation was provided to distribute water into the quarter and worm (micro) channels. The effect of this application caused the groundwater level to approach about 30 cm below the soil surface, while groundwater level in areas without pump irrigation facility was in the range of 50-60 cm. Besides efforts to increase the water table, liming is still required in order to increase production. Lime application of 1 Mg ha-1 had a significant effect on increasing production. Corn production with this treatment could produce 5 Mg ha-1, while non-treated land areas only produce 2-3 Mg ha-1.
