Abstract

The difference in the productivity level of paddy is caused by nutrient availability and land management. This study aims to determine the chemical properties of soil, especially elements of N, P, and K, in soils that have different levels of rice productivity. The methods used in this study are survey methods and laboratory analysis. Purposive sampling was conducted based on the productivity of medium and high-status rice fields. Based on the level of productivity of rice fields, there are 18 sample points, which are composite into 7 samples and analyzed in the laboratory. The results showed that several chemical properties in areas with high productivity levels had an average availability of total N nutrient status of 0.17% (low), potential P 56.5 mg 100 g-1 (high), potential K 17 mg 100 g-1 (low), organic C by 2.75% (medium), cation exchange capacity (CEC) 11.52 cmol(+)kg-1 (low) while in areas with medium productivity had an average total N nutrient of 0.23% (medium), potential P 38.33 mg 100 g-1 (medium), potential  K 72 mg 100 g-1 (very high), organic C 3.23% (high), CEC 33.06 cmol(+)kg-1 (high) and has a soil pH of 6.1 (slightly acid) respectively. High-productivity areas have low to medium soil fertility, while medium-productivity areas have medium to high soil fertility. Rice field management factors are suspected to cause differences in rice productivity levels.

Abstract

The Bogowonto River estuary is a coastal area in the open water category because it faces the Indian Ocean directly, it has high wave energy, which will cause erosion and abrasion, and the presence of mangrove and pond ecosystems (silvofishery) can support the development of coastal areas as conservation land. So it is necessary to conduct research to examine the influence of soil physical properties on silvofishing and determine the types of mangroves in the Bogowonto River estuary area. The method used was a survey, where soil samples were tested at the Yogyakarta BPTP Laboratory and the Yogyakarta "Veteran" National Development University at a depth of 0–20 cm and 20–40 cm. Sampling was conducted in a zigzag method from the left (near the pond) and right sides of the river. The results of the research found that there are 2 types of mangroves, namely the Tan cang (Bruguiera sp.), which grows far from the coastline and close to fish pond areas (silvofishery), has a has a relatively stable pH, is dominated by clay texture, and has a low salinity level. White Mangrove (Avicennia sp.) grows near the coastline, with a dominant sandy loam texture, low-normal pH, and high salinity levels. Mangroves that grow along the southern river in the presence of silvofishery can help with the deposition process of mud that is transported along the river and maintain the sustainability of fish populations, and litter from mangroves tends to increase the organic matter content of the soil.

Abstract

Mangrove forests can store four times more carbon than other tropical forests, mainly stored in the soil. This study aimed to evaluate the carbon content stored at two sediment depths (0-30 cm and 30-60 cm) with different vegetation density levels (very dense, medium, and sparse). The method used was a survey with purposive sampling and sampling using a 7.6 cm diameter PVC sediment corer. Parameters analysed included sediment texture, weight volume (BV), pH, salinity, and organic carbon content. The results showed that the denser the vegetation, the higher the stored carbon and the highest in the 30-60 cm depth zone, with a value of 184-403 tons/ha, while in the upper zone, 0-30 cm amounted to 29-210 tons/ha. In general, higher mangrove density levels had higher salinity, lower BV, but varying pH values with a range of neutral-slightly alkaline, and had a finer soil texture. The highest and lowest densities had salinities of (2.10-4.13 mS/cm) and (0.28-2.50 mS/cm), respectively, with BV values of 0.932 and 1.752 g/cm³.
