Ultisol is one of the soils with limited physical characteristics. The water content is low, the permeability is not enough to pass water into the soil, and the organic-C content is classified as moderate. So that it affects the soil in storing low water, one solution to overcome the physical characteristics of is to provide organic matter into the soil. The purpose of this study was to determine the physical characteristics of Ultisol and to determine the effect of the combination of organic matter from cow dung and rice husk ash on the soil water holding capacity of ultisols on dry land. This study was conducted at the Laboratory of Wira Wacana Christian University, Sumba. This study used a completely randomized design with six treatments and four replications. Observation data were subjected to analysis of variance followed by LSD advanced test with a confidence level of 5%. The results showed that the application of organic matter on the soil significantly affected water content, field capacity, permeability, and C-organic. The application of organic matter can improve soil structure, not soil texture gave a very significant effect, and the treatment that had the best water content was 75% cow dung + 25% rice husk ash.

High coffee production rates result in an increase in coffee waste, especially on the skin, which has not been used optimally. Inside the skin of the coffee fruit, there is 45.3% organic matter, 2.98% nitrogen, 0.18% phosphorus, and 2.26% potassium content which has the potential to be used as compost. The soil used in this research is Inceptisol soil type obtained from PTPN XII Bangelan Coffee Plantation, Malang. Inceptisol soil in this land has several problems, such as low soil fertility due to intensive use and improper fertilizer management. The use of compost can increase nutrient content and increase the pH value of the soil. This research was done in three different places at PTPN XII Bangelan for taking samples, Agriculture Faculty of Brawijaya University, especially in Soil Biology and Chemistry Laboratory for the incubation process and analysis of soil chemical characteristics. This research used a completely randomized factorial design with nine treatments and three replications. The nine treatments consisted of different soil depth such as (0 - 20 cm, 20 - 40 cm, and 40 - 60 cm) and three different dosages. The results showed that the application of coffee peel residue to soil significantly affected organic matters (organic-C) and phosphorus. For organic matters, soil depth that consisted most of it was 0 â€“ 20 cm (topsoil), and the fertilizer dosage that consisted most of it was dosage 0.58 g ha-1 and 1.16 g ha-1.

Soil quality is the ability of soil that plays a role in maintaining plant productivity, preserving and maintaining water availability and supporting human activities. Soil quality assessment is measured based on indicators that describe important soil processes based on the physical, chemical and biological properties of the soil. The level of soil quality in a plot of land is assessed based on the soil quality index. This research was conducted from August to December 2020 in the Supiturung Micro Watershed, Kediri Regency, East Java using a graphical survey method based on the Land Map Unit. Soil samples were taken at a depth of 0-20 cm at each observation point (20 points) for analysis in the laboratory. Soil quality indicators are determined based on key soil properties with the Minimum Data Set (MDS) method, with soil quality indicators from soil physical properties including texture, bulk density, porosity and soil chemical properties including pH, available-P, exchangeable-K, total-N, organic-C. Soil quality index was calculated by weighting soil quality indicators with criteria which divided into 5 classes, i.e. (i) very low class (0.00-0.19), (ii) low (0.20-0.39), (iii) moderate (0.40-0.59), (iv) good (0.60-0.79) and (v) very good (0.80-1.00). The results showed that the soil in land unit 2 had different limiting factor values on the percentage of sand and dust from the soil texture, the total-N content of the soil and the organic-C content of the soil which caused differences in soil quality. There are two indicators of soil quality, namely the percentage of dust from the soil texture and the total N content of the soil which has the most influence on the soil quality index.

Rice is an important commodity in human life where its production increase must be followed by environmental sustainability and land health. The achievement of increased rice production supported by environmental sustainability can be achieved by utilizing biological fertilizers. One of the microbes that can be used as nutrient providers for rice plants is cyanobacteria. This study was carried out in a greenhouse and soil biology laboratory of the Indonesian Soil Research Institute using a randomized block design with four replications. The treatments tested consisted of F0 (without treatment), F1 (wet cyanobacteria isolate), F2 (dry cyanobacteria isolate), F3 (cyanobacteria + rock phosphate), F4 (cyanobacteria + biochar), F5 (cyanobacteria + kaolin), F6 (cyanobacteria + rock phosphate + kaolin), F7 (cyanobacteria + rock phosphate + biochar), F8 (cyanobacteria + kaolin + biochar). The results showed that the cyanobacteria formula treatment with biochar (F4) carriers showed the highest total population in the parameters of the cyanobacteria population, bacteria, and fungi so that the interaction was said to be positive. The application of cyanobacteria formula to soil chemistry did not significantly affect the post-harvest soil N, P, and K, while the increase in soil pH occurred in the overall treatment of the cyanobacteria formula. Treatment of cyanobacteria formula with biochar carrier (F4) had significantly different results on parameters of number of tillers, number of panicles, grain weight, number of grains.

Agricultural practices, especially land clearing by burning in peat-land, usually causes land-fire and result in nutrient degradation of peat-land. The research was aimed to assess nutrient content (i.e. C, N, P) in oil palm plantation within peatlands post land fire. The study was conducted on Tulang Bawang regency, Lampung Province. Soil samples were collected from two locations with different intensity of land fire, i.e. field with low intensity of land fire (land A) and land with high intensity of land fire (land B). In each land, the soil was taken from two depths (i.e. 0-10 cm and 10-30 cm) in three different zones of oil palm plantation, named as fertilization area, frond stack, and harvested path, with three replications of each. The variable measured including soil organic C, total N, and available P. Prior to statistical analysis, the data were tested normality. The result showed that the location with low intensity of land fire (land A) had higher soil organic C, total N, and available P at 0-10 cm and 10-30 cm depths of soil as compared to the area with high land fire intensity (land B). Application of N fertilizer and liming resulted in a higher total N at 0-10 cm depth of soil and available P (in the land A) in fertilization area as compared to frond stack and harvest path areas, both in land A and land B. Available P in land B at 0-10 cm and 10-30 cm soil depth in the fertilization area was lower than harvest path and frond stack areas, and this was probably due to the high losses through leaching and/or uptake by palm oil.

Coal fly ash is a soil amendment that can be used to improve soil productivity because coal fly ash contains essential nutrients needed by plants. However, coal fly ash also contains heavy metals. This study was at a time to explore the effect of coal fly ash on soil chemical properties and lead uptake by vetiver plant (Vetiveria zizanioides L.). Treatments tested were applications of six proportion levels (0, 2.5, 5., 10, 15, and 30% by weight). The seven treatments were arranged in a completely randomized design with three replicates. The result showed that the coal fly ash had a significant effect on soil pH, total-P, total-N, total-K and Pb. The value of the Pb translocation factor from the roots to the shoot of the vetiver plant was relatively low, so that the vetiver plant was not suitable for use in phytoextraction of Pb from Pb-contaminated soil.

Land use in the upstream area of the Brantas watershed, including that inÂ Tawangsari village, Pujon District of Malang Regency, has undergone significant changes. The conversion of forest to moor, plantations, and settlements has resulted in decreased soil quality leading to soil degradation. The purpose of this research was aimed to compare the soil erodibility index determined by the rainfall simulator with Wischmeier methods. The results showed that there was a relationship between the results of the soil erodibility value using the Wischmeier method with land use and slopes based on the correlation and regression values caused by the physical properties of the soil. There were differences in soil erodibility index with the Wischmeier method and the Rainfall Simulator method, namely the average agroforestry results of 0.108 and 0.112 and an average of 0.152 and 0.147 moor. The use of the Wischmeier method is more recommended.

Fruit plants in Kediri Regency are classified as having good economic potential, one of which is pineapple. Pineapple plants in Kediri Regency have differences in productivity in each sub-district. The results of interviews with local farmers indicated that the Supiturung Micro Watersheds in Plosoklaten District had low pineapple productivity and were not yet optimal. Therefore, this study aimed to determine the factors causing differences and less optimal productivity of pineapples in the Supiturung Micro Watersheds and analyze the land suitability assessment of pineapple plants in the region. This study used a survey method with a physiographic approach to 10 Land Map Units (LMU) and determined 20 observation points as representatives. Data analysis was performed through correlation and multiple regression tests with the stepwise method to determine the land characteristics that most significantly affected pineapple productivity. Modification of the suitability class and modification of the criteria was carried out utilizing boundary line analysis, with class boundaries according to FAO (1976), namely class S1 (80-100%), S2 (60-80%), S3 (40-60%), and N (<40%) of the potential productivity. The land suitability evaluation results of pineapple plants in the Supiturung Micro Watersheds were included in land suitability classes S2, S3, and N. Based on the stepwise method analysis, the texture is a significant characteristic affecting the productivity of pineapples (p <0.05) with a correlation coefficient value of 0.838. The modification of land suitability criteria with boundary line analysis resulted in changes in one land characteristic, namely soil texture S2, S3, and N. Initially, the rough class included in the N class was changed to S2 level along with the slightly rough level.

PT. Great Giant Pineapple (PT. GGP) is the largest pineapple plantation company in Indonesia, with a land area of approximately Â±33,000 ha and dominated by soil types in the form of Ultisols. Soil fertility at PT. GGP tends to have relatively low nutrient content, one of which is phosphorus due to Al fixation. The nutrient P in pineapple is used to stimulate root growth, accelerate the ripening of fruit and seeds. Symptoms arising from P deficiency will experience stunted growth (stunted), and the pineapple will become imperfect. This study aimed to estimate the P nutrient content in pineapple plants using vegetation indexes in the form of GNDVI (Green Normalized Difference Vegetation Index). The study was carried out by taking aerial photographs and samples of pineapple plants in the 1 months phase before forcing and 1 months after forcing (F-1 and F+1), laboratory analysis, statistical analysis, and making distribution maps. The results showed that the vegetation index could estimate the nutrient content of P using the best estimation model. This was evidenced from the results of the correlation test which shows a very strong and real relationship of 0.81-0.82 with the regression test results of 66%-67%. In addition, the results of the validation test using the paired t-test showed that the t-count was smaller than the t-table of 2.30, which means that the estimated GNDVI vegetation index and the P nutrient content of pineapple plants showed no significant difference.
