Abstract

The utilization of steep lands by planting forestry and agricultural species can provide benefits from soil-water conservation and economic aspects. The combination of planting Neolamarckia cadamba-Phaseolus vulgaris and terrace systems can increase land use values, such as soil conservation, crop production, and farmers’ income. The aim of this study was to analyze silvicultural, hydro-orological, and economic aspects of a combination of forestry-agricultural crops (N. cadamba – P. vulgaris) and terrace systems on two slope classes. Two study plots were established on a steep gradient (25–40%) and a very steep gradient (>40%). The results showed an annual increase in the average diameter and height of N. cadamba of 1.78 cm and 1.84 m, respectively on the steep slope, and 1.68 cm and 1.53 m, respectively on the very steep slope. The surface run off and erosion rate were lower on the steep ground compared to the very steep ground. Erosion hazard indices and levels on the plots in the steep slope and very steep slope were categorized as low and very low; meanwhile the erosion hazard class was I. The profit of P. vulgaris cultivation was IDR 9,360,000.00 ha–1 per cropping season on steep slope and IDR 6,480,000.00 ha–1 per cropping season on very steep slope. The planting of P. vulgaris as an intercropping plant to fill empty land in between N. cadamba can increase the economic value obtained from selling P. vulgaris in the short term until the leaves of the N. cadamba plant are linked. The combination of planting N. cadamba–P. vulgaris and terrace system on steep slopes is therefore more profitable not only from the economic perspective, but also in lowering runoff and potential erosion rates than on very steep lands.

Abstract

Detailed studies of Ni distribution in peat that is influenced by Ni-rich soil derived from ultrabasic rocks are still limited. The objective of this study was to reveal the characteristics of Ni in peat from Morowali (Central Sulawesi Province, Indonesia) at several depths and distances from the boundary of the ultrabasic mineral soil. Peat was sampled from depths of 0–30, 30–60, and 60–90 cm at distances of 100, 200, 300, 400, 500, and 600 m from the border of the ultrabasic mineral soil in March 2018. Ni characteristics were examined through their total, exchangeable, water-soluble, and adsorbed distributions. The relationships between Ni and some peat chemical properties such as pH; cation exchange capacity; macronutrient contents of K, Ca, and Mg; and micronutrient contents of Fe, Cu and Zn were also observed. The high Ni content in peat at the study transect is caused by an accumulation of Ni transported from elevated areas of mineral soil. Most Ni in peat is bonded to the soil organic exchange complexes. Accumulation of the mineral soil fraction in the peat surface is indicated at distances of 100–400 meters from the ultrabasic mineral soil. Ni distribution in peat at the study transect is mainly governed by a combination of Fe, pH, organic material, water content, peat depth, and distance from ultrabasic mineral soil.

Abstract

Indirect estimate of solute-transport parameters through pedo-transfer functions (PTFs) is becoming important due to expensive and time-consuming direct measurement of the parameters for a large number of soils and solutes. This study evaluated the relative performance of PTFs of multiple linear regression (MLR) and Artificial Neural Network (ANN) models in predicting velocity (V), dispersion coefficient (D) and retardation factor (R) of CaCl2, NaAsO2, Cd(NO3)2, Pb(NO3)2 and C9H9N3O2 (carbendazim) in five agricultural soils. V, D and R of the solutes were determined in repacked soil columns under steady-state unsaturated water flow conditions. Textural class, particle size distribution, bulk density, organic carbon, relative pH, clay%, grain size, and uniformity coefficient of the soils were determined. MLR and ANN models were calibrated with the measured data of four soils and verified for another soil. Root-Mean Square Error (RMSE) is significantly smaller (0.015) and modelling efficiency (EF) is significantly larger (0.999) for ANN model than those (0.096 and 0.954, respectively) for MLR model. Negative Mean Absolute Error (MAE) (-0.0002) of MLR model indicates overestimation, while positive MAE (0.00003) of ANN model indicates minimal underestimation. The ANN model is less biased than the MLR model during prediction. Thus, the ANN model can significantly enhance pollution transport prediction through soils with good accuracy.

Abstract

Nitrification, or the process of oxidation of ammonium to nitrate in the soil, needs to be inhibited because it reduces the efficiency of nitrogen fertilizers. Vertisols have 2:1 minerals and have high negative charge, so ammonium is more absorbed by soil particles, whereas nitrate is free to move in the soil and diffuses into the plant tissue or is leached with gravity water. This study aimed to determine the litter treatment that can inhibit the nitrification process in Vertisols on sweet corn plants. This research was conducted in June until November 2019 in the Plastic House of Plesungan, Gondangrejo, Karanganyar, Indonesia. This study used a basic completely randomized design with a single factor (litter type) as an immobilizer. The types of litter used in this study were Gliricidia maculata, Albizia falcataria, Senna siamea, and Tithonia diversifolia. The parameters observed were ammonium content, nitrification potential, average nitrate content, actual nitrification, plant height, number of leaves, and dry crown plant. Tithonia diversifolia gave the highest actual nitrification of 23.26%. Senna siamea has the lowest actual nitrification of 12.36%, followed by Gliricidia maculata with 17.39% and Albizia falcataria with 17.67%. This shows that the Tithonia diversifolia litter has the highest value in inhibiting nitrification. Maize plants treated with the Tithonia diversifolia litter had the best plant growth compared to those applied with other treatments. Therefore, among the treatments used, the Tithonia diversifolia litter was most optimal in inhibiting nitrification in Vertisols.

Abstract

The water supply for rainfed crops such as bananas in the Aragua state of Venezuela is often uncertain, particularly towards the beginning of the rainy season (April-May). Where climatic conditions are seasonal, the temporal evolution of the NDVI (Normalized Difference Vegetation Index) closely accompanies the interannual variation of vegetation growth in response to thermal and hydric factors. The aim of the study is to assess the relationship between NDVI, rainfall and potential evapotranspiration during the period of January/2016 to December/2017 in a Venezuelan banana plantation. In this study, the NDVI derived from the GIMMS MODIS Terra product, the daily accumulated precipitation data (mm) and the daily mean air temperature (°C) were used as the only way to estimate the potential evapotranspiration. The results showed that the GMOD09Q1-based NDVI reflects reasonably well the spatiotemporal variation in biomass accumulation. Besides, this provides information on the water stress conditions in banana plants at the plot level. The influence of Precipitation and potential evapotranspiration on the NDVI was more evident when a lag of 1 month was considered in terms of the Spearman r, implying that there is a delay in the banana phonological response to rainfall changes and dryness conditions.  However, due to its low spatial resolution (i.e. 250 m), it is not adequate for the identification of banana wilt disease. Therefore, future studies are needed to assess other satellite-derived spectral indices for monitoring the health of banana plants over different sites in Venezuela.

Abstract

Agricultural constraints on sandy soil are poor chemical characteristics and low biological activity resulting in the soil becoming less productive to be planted. One of the efforts to improve the quality of sandy soil are application of mycorrhizae and a soil ameliorant. The purpose of this study was to determine the effect of mycorrhizae and a soil ameliorant on soil chemical characteristics and soil biological activity. The experiment was arranged using a Complete Randomized Design that had two factors. The first factor (1) was mycorrhizae dose, without mycorrhizae (M0) and six spores of mycorrhizae/plant (M1), and the second factor (2) was types of soil ameliorant, without ameliorant (S0), cow dung (S1), rock phosphate (S2), biochar (S3), cow dung–rock phosphate (S4), cow dung–biochar (S5), and rock phosphate–biochar (S6). The results indicated that combination of six spores mycorrhizae/plant–cow dung 60 tons ha−1–biochar 25 tons ha−1 (M1S5) increased soil organic carbon (SOC) (235%), available P (675%), cation exchange capacity (CEC) (216%), total glomalin (101%), and easily extracted glomalin (69%), decreased exchangeable sodium percentage (66%), and increased absolutely for root infection and spore density than without mycorrhizae and a soil ameliorant (control). The lowest of SOC in non-mycorrhizae and rock phosphate, available P, CEC, root infection, spore density were found on the control, but the lowest of total glomalin and easily extracted glomalin were found on non-mycorrhizae–rock phosphate. The application of mycorrhizae, cow dung, and biochar improved the sandy soil characteristics.

Abstract

The soft clay soil has been categorized as infertile soil. The occurrence of soft clay soil in paddy field areas can decline soil quality and rice production. Therefore, to find the best technique for amending this soil, this study aimed to analyze the physical, chemical, and microstructure properties of the soft clay soil in the paddy field area. The soft clay soil samples were collected from two paddy blocks in Kedah, Malaysia. The physical and chemical properties of the soil were determined using the standard method in the laboratory. The microstructure properties were analyzed using Zeiss SUPRA 55VP microscopes. The results found that the soft clay soil was composed of silt – clay (> 90%) with the texture of silty clay. The soft clay soil was characterized by low values of organic matter (2.63-3.42%), pH (3.32-3.69), cation exchange capacity (6.89-8.72 cmolc kg-1), available P (0.14-0.41 mg kg-1), aggregate stability (16.53-17.78%), and hydraulic conductivity (0.17 cm hr-1). In contrast, it indicated high values of soil water content (42.24-43.21%), and exchangeable Na+ ions (2.48-2.50 cmolc kg-1). In addition, the analysis of heavy metals content revealed that their concentrations were below the critical level in the soil. The soft clay soil was largely governed by kaolinite minerals, and it had less compact structures with many large voids among soil aggregates. In conclusion, the quality of soft clay soil in the study area was poor with low physical and chemical parameters. The quality of the soil could be improved by the addition of soil amendments such as zeolite, cement, and other additive materials to absorb the excess water in the soil and increase the soil strength.

Abstract

Plant growth-promoting bacteria (PGPB) have become an important subject of research to increase maize production. The PGPB consortium should provide more benefits than single or dual inoculation. This study aimed to investigate the effect of a PGPB consortium on improving maize growth and yield. The field experiment used a split-plot design. The main plot consisted of three maize varieties (Talenta, Pertiwi-3, and Bisma), and the subplot consisted of three formulations of PGPB consortia [endophytic bacteria isolates, Acetobacter sp., cellulolytic, and ligninolytic (F1); endophytic bacteria isolates, Azospirillum sp., cellulolytic, and ligninolytic (F2); and endophytic bacteria isolates, cellulolytic, ligninolytic, Acetobacter sp., and Azospirillum sp. (F3)] and one control. PGPB consortia formulation did not influence maize growth significantly, but maize varieties did. Pertiwi-3 showed the highest value in all growth variables, followed by Bisma and Talenta, respectively. The effect of PGPB consortia formulation upon ear fresh and dry weight depends upon the maize variety, and Pertiwi-3 showed the highest value in yield variables. PGPB consortia formulation 2 was the most effective to apply for Pertiwi-3 cultivation, while PGPB consortia formulation 3 produced higher yields for Talenta and Bisma. These findings indicated that specific PGPB formula could improve the yield for specific maize varieties.

Abstract

Laboratory study was performed to assess the impact of humification degree of humic acids isolated from composted rice straw (RS) and olive pomace (OP) on the metal loading capacity of extracted humic acids with Fe, Mn and Zn at different pH values (4, 5 and 6). The results revealed that the highest values of total acidity, carboxyl and phenolic-OH groups were achieved by HA-c extracted from compost C. Both HA-c and FA-c realized more pronounced values of total carbon and nitrogen content. Adversely, HA-c and FA-c achieved less pronounced values of oxygen and hydrogen as well as H/C, O/C and C/N atomic ratios. The loading capacity of Fe+2 reached to optimum values at pH 5 for all studied humic acids. While the maximum loading capacity of Mn+2 or Zn+2 was achieved at pH 6. In this respect, the maximum loading capacity of Fe+2, Mn+2 and Zn+2 were obtained for HA-c followed by HA-d.

Abstract

The abiotic factors have a wide effect on the growth of plants along with the cultivation of staple crops.  The concentration of both essential and non-essential elements is impacted by number of biogeochemical factors. The low pH (≤5.0) of the soil is one such factor which poses variation in the levels of metal ions and mostly it leads to metal toxicity. The excess concentrations of the elements in the soil affects the growth, yield and the metabolic activities of the plants making them susceptible. However, some of the genotypes adapt themselves to metal toxicity condition by regulating their homeostatic genes leading to develop different strategies to undergo detoxification method. In the present review we discuss about the toxicity of Al, Fe and As which is a non-essential metal, an essential metal and an unwanted heavy metal. In a broad picture, to escape the toxic effects, plants have the strategy to exclude the excess metal outside the plant or include it in its storage cells. The insight of the present review aims at understanding these strategies in details which can be put into agricultural applications for developing better crops.
