Abstract

Water and nutrients is important for plant which has its characteristics. This study has been carried out in the UB (Brawijaya University) forest about soil moisture content during rainy and dry seasons, Total-N, -P, -K from litter on different types of shade and age of coffee plants, and their effect on soil Available-N, -P, and -K. There are P1 (control), P2 (4-year-coffee + pine), P3 (7-year-coffee + pine), P4 (4-year-coffee + mahogany), and P5 (7-year-coffee + mahogany). These treatments affected to total soil moisture storage, Total-N, -P, -K of litter, and Available-N, -P, -K in the soil. The soil moisture storage change between rainy and dry seasons was 36.97 mm. The highest Total-N, -P, and -K of litter was 11.00 kg ha-1 y-1 at P3, 1.06 kg ha-1 y-1 at P2, and 4.35 kg ha-1 y-1 at P3, which was inconsistently associated with high soil nutrients. The highest Total-N was 0.40 (0-20 cm), 0.27 (20-40 cm), 0.30% (40-60 cm) at P4, Available-K was 1.69 (0-20 cm), 1.64 (20-40 cm), 1.87 cmol kg-1 (40-60 cm) at P5, and Available-P was 15.21 (0-20 cm), 14.06 (20-40 cm), 12.64 mg kg-1 (40-60 cm) at P1.

Abstract

Watershed hydrological conditions can decrease due to changes in land use and inappropriate land management. One of the watershed functions is providing water availability for agricultural areas. Along with the increasing area of agricultural land, there is often the issue of water availability, which has implications for the low opportunity for plants to use it. Infiltration is the initial process of water entry into the soil, so the availability of water is greatly influenced by this process. Agricultural land in the Kalisari sub-watershed is dry land and is dominated by dry fields. The area of the Kalisari sub-watershed has an area of ±5,000 ha divided into 5 land uses, namely mahogany-coffee agroforestry, pine-coffee agroforestry, scrub, dry land, and paddy fields. Infiltration measurements were spread over 43 measurement points, with the observed parameters being texture, bulk density, porosity, permeability, aggregate stability, and soil organic matter. The infiltration rate for all land uses is very fast (>25 cm hour-1), ranging from 12.00 cm hour-1 to 74.37 cm hour-1. The infiltration rate for all land uses was not significantly different; this was in line with soil properties, which included texture, bulk density (0.61-1.02 g cm-3), porosity (51.02-68.06%), permeability (4.88–6.79 cm hour-1), aggregate stability (2.11–3.34 mm), and organic matter (1.61-4.06%). However, the infiltration rate at the study site had a significant relationship with clay (r = -0.77), sand (r = 0.64), silt (r = 0.52) and soil organic matter   (r = 0.48).

Abstract

The application of ZnO-coated urea is a promising strategy to reduce nitrogen losses and improve zinc availability in soils. This study aimed to evaluate the effects of ZnO-coated urea on soil ammonium concentrations and ureolytic bacterial populations. A completely randomized design was used with five treatments:control (CU), uncoated urea (CU) and ZnO-coated urea at three different coating (bulk ZnO (NCU-Z), ZnO NPs (NCU-ZNP), and  ZnO NPs combined with bentonite NPs (NCU-ZBNP)), each with four replications. Soil samples were incubated on sterile jars under controlled conditions for 8 weeks and used loamy soil as a medium. Ammonium concentrations were measured using the spectrohotometry, while ureolytic bacteria were enumerated using the total plate count (TPC). NCU characterization results revealed inconsistencies in coating thickness, however, it has shown significant results on soil ammonium content and total ureolytic bacteria population. Results on the number of ureolytic bacterial populations showed that NCU-ZNP treatment could reduce the number of bacteria up to 77.8%. The research results also showed that the NCU-ZBNP treatment significantly maintained soil ammonium levels that were 1.76 times higher compared to CU.These findings suggest that ZnO-coated urea can slow nitrogen transformation and potentially improve nitrogen use efficiency while influencing soil microbial communities.

Abstract

Monitoring  lemon production requires appropriate and efficient technology. The use of UAVs can addressed these challenges. The purpose of this study was to determine the best vegetation indices (VIs) for estimating chlorophyll content, plant height (PH), canopy area (CA), and fruit total numberas (FTN). CCM 200 was used as a tool to measure the chlorophyll content index (CCI), the number of fruits was measured by hand-counter, and other variables were recorded in meters. The UAV used was a Phantom 4 with a multispectral camera capable of capturing five different bands. The VIs was obtained via analysis of digital numbers generated by the multispectral camera. Then, the VIs was correlated with the CCI, PH, CA and FTN. VIs tested included the following: the normalized difference vegetation index (NDVI), the normalized difference vegetation index-green (NDVIg), the normalized different index (NDI), green minus red (GMR), simple ratio (SR), the Visible Atmospherically Resistant Index (VARI), normalized difference red edge (NDRE), simple ratio red-edge (SRRE), the simple ratio vegetation index (SRVI), and the Canopy Chlorophyll Content Index (CCCI). The best model for predicting CCI was obtained using the NDVIg (R2=0.8480; RMSE=6.1665 and RRMSE=0.0908). Meanwhile, SR turned out to be the best model for predicting PH (R2=0.8266; RMSE=15.6432 and RRMSE=0.0883), CA (R2=0.6886; RMSE= 0.8826 and RRMSE=0.1907), and FTN (R2=0.6850; RMSE=24.5574 and RRMSE=0.3503). The implication of these results for future activities includes establishing early monitoring and evaluation systems for lemon yield and production. This model was developed and tested in this specific location and under these environmental conditions.

Abstract

Spring ecosystems in forest fragments provide important environmental services, but their economic value is rarely included in management decisions. Most management efforts focus only on physical protection, while the way visitors value these ecosystems receives little attention. This study aims to estimate the economic value of spring ecosystem services and analyze the factors influencing visitors’ willingness to pay (WTP). This study also examines the relationship between WTP, water quality indicators, and differences in ecological conditions across several categories of forest fragments. Observations were conducted at sixteen spring locations in East Java, Indonesia. These locations represent large and small forest fragments and two management orientations, namely instrumental and relational. Data on the social and psychological characteristics of visitors were combined with several biophysical indicators, including water quality. Principal component analysis (PCA) was applied to analyze these variables, and economic efficiency was evaluated using an adjusted land equivalent ratio (LER). The results show that WTP is more influenced by visit experience, visitor trust in management, and perceived benefit efficiency than by basic demographic characteristics alone. Fragments with an instrumental orientation show higher economic efficiency compared to those with a relational orientation. Meanwhile, water quality in fragments with a relational orientation is much better, as indicated by high DO and TDS levels and greater and more stable discharge values. These findings indicate differences between economic performance and ecological conditions across forest fragment categories. Therefore, integrating social, ecological, and governance dimensions is essential for developing effective conservation strategies for springs in forest fragments.

Abstract

Composting is an alternative way to accelerate decomposition and maturation of residual waste from refining leaves of cajuput to be suitably applied to the soil. The application of Cajuput Waste Compost (CW Compost) is intended to increase the productivity of sandy soil in Indonesian dryland. Compost serves as a soil conditioner that can improve the physical, chemical and biological properties. The study aimed to determine and analyze the role of CW compost in improving the physical quality of sandy soil in two incubation periods. The study used experimental methods, through soil incubation that given CW compost, in a greenhouse with two incubation periods. The experiments used a completely randomized design with 4 levels of CW compost treatment, namely: 0 t/ha (P0), 10 t/ha (P1), 20 t/ha (P2), 30 t/ha (P3). The results showed CW compost had a significant role in improving the physical quality of sandy soil both at 1-month and 4-month incubations. The soil physical quality increased by increasing compost levels and incubation periods, except for the total available water variable which decreased after 4-month incubation. The decrease was allegedly due to the reduction of labile fraction in the soil

Abstract

The biopore infiltration hole with organic material litter can increase the soil capacity to accommodate and store soil moisture. This study was aimed to determine the effect of biopores and organic material litter on soil moisture storage and the relationship of climatic conditions on soil moisture storage. The experiment was carried out on clove plantations on Ternate Island, North Maluku from December 2018 to February 2019. This study used a factorial randomized block design. The first factor was the biopores with a depth of 50 cm and 90 cm, and the second factor was 4 types of organic material litters in the form of nutmeg leaves, clove leaves, Guinea grass leaves and a mixture of clove leaves and Guinea grass. The factors observed were total soil water storage and at depths of 0-20, 20-40, 40-60 and 60-80 cm; organic matter content; C/N ratio and soil total N. Data analysis used the GenStat program with analysis of variance test (ANOVA) and Duncan's Multiple Distance Test. Results of the study showed that evaporation and percolation are climatic factors that affect water loss. Increase in soil water storage at 20-40 cm soil depth of 107.56 mm was yielded by the treatment of 50 cm biopore and Guinea grass leaf litter but it was not significantly different from the 50 cm biopore and clove leaf litter + chicken manure treatment. The treatment of biopore and organic material litter also increased the organic matter and soil total N and decreased the soil C/N ratio, but it did not have a significant effect.

Abstract

Coffee plantation management has an important role in soil quality in order to increase coffee production. Biopore Infiltration Hole with Compost (BIHC) can increase soil available water capacity. In this study, the goal was to improve soil available water capacity in a coffee plantation with the implementation of the BIHC. This study was conducted at PTPN XII Bangelan, Malang, on March - August 2020. A randomized block design with seven treatments and four replications was used. The BIHC consisted of two-hole depths (30 cm and 60 cm) and two types of compost (goat manure and coffee pulp compost). The soil characteristics observed were water retention (pF) and C-organic at soil depths of 0-20, 20-40, and 40-60 cm. The coffee tree observed were number of leaves and chlorophyll content. Data obtained were subjected to analysis of variance (ANOVA) by the F test and Duncan's Multiple Distance Rate  Test (DMRT) at 5% probability, using SPSS program. Results of the study showed that BIHC was able to increase the content of soil C-organic and the available water capacity significantly compared with control treatment. The BIHC implementation could increase soil available water capacity up to 65% at a soil depth of 0-20 cm, up to 60% at a soil depth of 20-40 cm, and up to 51% at a soil depth of 40-60 cm more than the control treatment. The soil available water capacity suggested a significant positive correlation (p≤0.05) with the leaves number of coffee tree and chlorophyll content of leaves.

Abstract

Climate change and the erratic and uneven rainfall distribution are the causes of reduced water available in the soil for plant needs to the transpiration process. This study aimed to determine coffee transpiration rate on dry land with rain harvesting techniques during the dry season, transition season, and rainy season and the factors that influence it. This study used field observation and laboratory analysis with two treatments, i.e. a bench terrace as a control (P1) and an L-shaped silt pit (P2). The variables observed were soil moisture content, transpiration rate, soil water potential, leaf water potential, and microclimate, especially temperature and sunlight intensity. The results showed that the transpiration rate of coffee plants was significantly different in the two treatments. The highest transpiration rate was found in P2 as much as 13.17 mm week-1 or equivalent to 1.88 mm day-1 during the dry season. Application of the L-shaped silt pit (P2) increased soil moisture content compared to the control (P1). This increase was followed by an increase in soil water potential and leaf water potential, which could reach the highest values of 0.18 bar and 0.49 bar, respectively. The transpiration decreases with the change of seasons from the dry season to the transitional season and the rainy season. This decrease is caused by changes in the microclimate, especially the temperature and sunlight intensity. Both are the most variables that affect the rate of transpiration.

Abstract

A study on the addition of organic matter of different qualities was carried out to improve plant growth on a degraded sandy soil of Bambang Village, Wajak Malang, East Java. Two potential sources of organic matter in Bambang Village are Tithonia diversifolia and sugarcane leaves. This study aimed at elucidating the changes in some chemical properties of a degraded sandy soil of Malang, East Java, and nutrient uptake and growth of maize plants by applying mixtures of Tithonia diversifolia and sugarcane leaves of different quality. Treatments tested in this study were mixtures of Tithonia diversifolia leaves and sugarcane leaves at various proportions (%w/w), i.e. 100% Tithonia diversifolia leaves (T1), 100% sugarcane leaves (T2), 75% Tithonia diversifolia leaves + 25% sugarcane leaves (T3), 50% Tithonia diversifolia leaves + 50% sugarcane leaves (T4); without organic matters (T6), and control, without organic matter and inorganic fertilizers (T7). The results showed that the application of Tithonia diversifolia and sugarcane leaves affected soil pH, soil exchangeable bases, maize growth, and nutrients uptake. Nutrients taken up by maize plants significantly increased with the addition of Tithonia diversifolia leaves, either alone or in combination with sugarcane leaves. The application of 100% sugarcane leaves did not significantly affect maize growth and nutrient uptake.
