<p>Soil fertility status describes soil characteristics and soil suitability with the plants to be cultivated. This study aims to identify the variable soil fertility that becomes an obstacle in several villages in the Beringin District. This research was conducted in the villages of Aras Kabu, Kelapa, and Serdang, Beringin District, Deli Serdang Regency. This research is descriptive using the survey method. Sampling of soil in the survey area was carried out sequentially with a purposive random sampling method. The results showed that the total N status in the three villages was classified as low. Where the total N value in Aras Kabu village was 0.13%, Kelapa village 0.12% and Serdang village was 0.21%. Phosphorus in the research field is classified as high. In the village of Aras, the district was 19.57 ppm, Kelapa village 19.27 ppm and Serdang village 13.19 ppm. The K<sub>2</sub>O value in the study area was also low, where the village of Aras Kabu was only 19.96 mg K<sub>2</sub>O/100 g, Kelapa village 18.56 mg K<sub>2</sub>O/100g and Serdang village 25.47 mg K<sub>2</sub>O/100g. The use of P fertilizers can be reduced as an implication of the status of P nutrients available in high land, while to increase the low levels of N and K nutrients, it can be done by providing organic matter in the form of fertilizer (compost or cage) or returning post-harvest straw to the land. </p>

A study was carried out to evaluate the effects of brick manufacturing on phosphorus (P) and sulfur (S) concentrations in soil and plant collected from different distances of brick kilns in four AEZs of Bangladesh. Forty eight composite soil samples (0 - 15 cm depth) were collected from 48 points in 12 different sites at 0 m, 300 m, 800 m and 1500 m from brick kilns, where most (site 2, site 3, site 5, site 6, site 7, site 9 and site 10) of the brick kilns used coal for brick burning purposes. Plant samples (rice straw and different vegetables) were also collected from the respective fields except 0 m distances. Significantly (p ? 0.05) lower organic matter, cation exchange capacity, clay content and soil pH were found at 0 m distances compared to other distances. Highest concentration of total P in soil were recorded at 0 m distances and these concentrations decreased with increasing distances from the brick kilns in most of the sites; whereas available P is significantly lower at 0 m distances than that of other distances. Total and available concentration of S in soil followed the trend 0 m>300 m>800 m>1500 m. Maximum accumulation of P (69.15 mg kg-1) and S (0.14%) in plant was found at 800 m away from the brick kiln.Bangladesh J. Sci. Res. 29(2): 123-131, December-2016

Mapping using Geographic Information System (GIS) in food crops is an efficient and effective way to know land characteristics and their development potential in determining land suitability class in a region. This study aims to investigate the suitability class of food crops in the Krueng Pase River Basin (DAS) of North Aceh Regency, which starts from December 2016 until March 2017. The method used in this study is a survey method consisting of the preparation stage, survey introduction, main survey, data analysis and presentation of results. Some soil properties that affect land suitability classes for food crops are soil texture, cation exchange capacity (CEC), pH, basic saturation (KB), C-organic, Nitrogen, Phosphorus and Potassium. The results showed that the land suitability class for rainfed lowland rice on SPL 29, SPL 30 and SPL 31 was marginal (S3) with drainage limiting factor, phosphorus, potassium, slope and erosion hazard. Unsuitable land suitability class (N) with slope limiting factor and erosion hazard is found in SPL 26. The soil suitability class for corn and soybean is marginal (S3) with texture limiting factor, C-organic, phosphorus, potassium, slope and hazard (SP), SPL 17, SPL 18, SPL 20, SPL 21, SPL 22 and SPL 23. While the land suitability class is not suitable (N) with slope limiting factor and erosion hazard is found in SPL 15. The suggested soil conservation techniques are drainage drainage, organic and inorganic fertilizer application combined, and the making of guludan terraces

The world's tropical rainforests are decreasing at an alarming rate as they are converted to agricultural land, pasture, and plantations. Decreasing tropical forests affect global warming. As a result, afforestation progams have been suggested to mitigate this problem. The objective of this study was to determine the carbon and phosphorus accumulation of a rehabilitated forest of different ages. The size of the study area was 47.5 ha. Soil samples were collected from the 0-, 6-, 12-, and 17-year-old rehabilitated forest. Twenty samples were taken randomly with a soil auger at depths of 0–20 and 20–40 cm. The procedures outlined in the Materials and Methods section were used to analyze the soil samples for pH, total C, organic matter, total P, C/P ratio, yield of humic acid (HA), and cation exchange capacity (CEC). The soil pH decreased significantly with increasing age of forest rehabilitation regardless of depth. Age did not affect CEC of the rehabilitated forest. Soil organic matter (SOM), total C, and total P contents increased with age. However, C/P ratio decreased with time at 0–20 cm. Accumulation of HA with time and soil depth was not consistent. The rehabilitated forest has shown signs of being a C and P sink.

Jember district is one of the centers for smallholder plantation of the Robusta coffee in East Java. However, there are still limited reports about environmental conditions, particularly soil fertility of existing smallholder plantations and its effect on coffee flavor. The purpose of this study was to investigate the effect of soil fertility on flavor of coffee in existing smallholder Robusta coffee plantations in Jember district. This research was carried out by survey method in several area of the smallholder Robusta coffee plantation in Jember. Evaluation of sensory profile was carried out using cup test organoleptic method based on Standard cupping method of the Specialty Coffee Association of America. Research locations as subdistricts were chosen by purposive sampling method, namely Panti, Silo, Rambipuji, Sukorambi, and Tanggul subdistricts. Results of this study showed that soil of the smallholder Robusta coffee plantation in research locations possessed low organic carbon content in Sukorambi subdistrict and medium concentration in other locations. Nitrogen content was low in all locations, potassium in Sumber Baru subdistrict was high whereas other locations were medium. Phosphorus availability was high in all locations. Calcium and magnesium were medium in Panti, Sukorambi, Sumber Baru, and Silo subdistricts. Soil acidity was low in all locations. Results of the sensory analysis of smallholder’s Robusta coffee was from divided into three groups. First, categorized as fine Robusta coffee was smallholder’s Robusta coffee samples obtained from Silo and Sukorambi subdistricts. Second, good quality Robusta coffee was from smallholder Robusta coffee samples from Panti and Sumber Baru subdistricts. Third, medium quality Robusta coffee was from smallholder’s Robusta coffee from Tanggul subdistrict. Total scores of coffee testing from samples of Panti, Sukorambi, Sumber Baru, Tanggul, and Silo subdistrict were 79.8, 82.0, 79.9, 76.0, and 82.5, respectively

Natsepa Beach has a natural beauty that attracts tourist arrivals and is managed by the Central Maluku Regency Government. The existence of covid-19 has a significant impact on local people’s income and local labor. The purpose of this study is to descriptively compare the presence of Covid-19 to the village of the business in the Natsepa beach. The research method used is the survey method, and the sampling method used is nonprobability sampling. The results showed that the average number and quality of tourism services significantly declined inside and outside the location. During the pandemic covid, the revenue of the business unit/month in the Natsepa beach decreased from IDR.1920000 to IDR.725500; business unit outside the Natsepa Beach tourist attraction from IDR.1850105 to IDR.826725 and the community around the Natsepafrom IDR.1830698 to IDR.1278540,-. The economic impact value at the usual time (2018) compared to 2020 was obtained from KIM, namely from 2.04 to 0.84; the importance of RIM I, 1.59 to 1.33, and RIM II 2.31 to 1,73. The conclusion of this study shows that local communities have experienced a drastic decline in income so that they need to be supported by the government.
