Abstract

Earthworms are important soil biota that can be used as  an indicator of soil fertility. Soil tillage systems and application of organic mulch will affect the activity of earthworms. This research was aimed to study the effect of tillage systems and the application of in situ mulch, and their interactions on the population and the biomass of earthworms. The study was conducted from April to July 2017 at the Integrated Field Laboratory, Faculty of Agriculture, University of Lampung. The study was arranged in a Randomized Block Design (RBD) in a factorial treatment with two factors.  The first factor was the tillage system  which consisted of the minimum tillage and the intensive tillage. The second factor was the application of in situ mulch, which consisted of the application of 0 Mg ha-1 or without mulch and the application of 5 Mg ha-1  in situ mulch.The data obtained were tested for homogeneity of variance with the Bartlett Test and its additivity with the Tukey Test. Data were further analyzed for the analysis of variance and for the LSD’s Test at the level of 5%. The relationship between soil temperature, soil moisture content, soil organic-C and soil pH with population and biomass earthworm was tested by correlation test. The results showed that the earthworm population and the earthworm biomass at 80 DAP in the minimum tillage  was higher than that of the intensive tillage. The earthworm population for all detected planting stages (before tillage, 40 DAP and 80 DAP) with the of application of 5 Mg ha-1 in situ mulch was higher than that of the application of no mulch.  There is no interaction between the tillage system and the application of in situ mulch at 0 DAP, 40 DAP, and 80 DAP.  The genus of earthworms found in all treatment plots was genus Pheretima under the family of Megascolecidae.

Abstract

Several particular plants are suggested to extract significant parts of heavy metals from soils and accumulate them in their roots and shoots.  This research aimed to study the phytoextraction of Cu by several plants from heavy-metal contaminated tropical soils.  Soil samples collected from plots treated in 1998 with 0, 15 and 60 Mg industrial waste ha-1 were planted with three different plants, i.e., caisim, water spinach, and lettuce.   Plant parts (roots and shoots) and soil samples were harvested after a four-week growth period and analyzed for plant and soil Cu.  The results show that the growth of plants was depressed by the increase in the soil Cu (extracted by 1 N HNO3) as affected by waste levels, with water spinach being the most progressive and produced the most significant biomass.  The absorption of Cu by caisim and water spinach increased with the soil extracted Cu (linear R2 = 0.71* for caisim and 0.32* for water spinach) and accumulated greater in plant roots than that in shoots. The translocation factor (TF << 1.00) indicates that all plants were good Cu phytostabilizators rather than phytoextractors, with water spinach being the best Cu extractor.

Abstract

Ultisol soil has a low organic matter content, CEC, and pH, causing an insufficient buffering capacity for N nutrients, especially NH4+. The objective of this study was to determine the effect of tillage and fertilization on the quantity and intensity (Q/I) of Ammonium (CRNH40, PBCNH4+, NH40, KG) in the soil, plant N and C uptake, and mung bean yields at the sixth growing season in ultisols. This study was arranged in a 2 × 2 factorial in a Randomized Block Design (RBD). The first factor was the tillage system (T), namely minimum tillage (T0) and intensive tillage (T1). The second factor was the fertilization (P), namely without fertilizer application (P0), and with fertilizer application (NPK 200 kg ha-1 + 1 Mg ha-1 chicken manure) (P1). Each treatment was replicated four times. The results showed that the application of NPK fertilizer significantly affected the mung bean yield, mung bean plant Nitrogen and Carbon uptake at harvest time. While, the intensive tillage had a very significant effect on increasing the N uptake compared to the minimum tillage. Minimum tillage and fertilization increased Q/I parameters (PBCNH4+, KG, CRNH40, and NH40). The parameter of Q/I (CRNH40) was significantly correlated with mung bean plant N and C uptake. PBCNH4+ and KG were significantly correlated with mung bean yields.

Abstract

Studying the weathering process in pristine volcanic materials is crucial as this process will determine further soil characteristics. Mount Anak Krakatau is reported as one of the fastest-growing volcanoes. This volcano erupted powerfully in December 2018, ejecting tons of volcanic materials. These materials are considered pristine and unweathered tephra. Hence, a leaching experiment can be one of the crucial methods to predict further soil characteristics formed as climatic factors. Tephra sampling was conducted on 13 Augustus 2019 or eight months after the massive eruption of Mount Anak Krakatau in December 2018. Tephra samples were leached by deionized water (H2O), oxalic acid (H2C2O4) 0.02 M, and citric acid (C6H8O7) 0.02 M (solvents) for 90 days. pH of tephra increased approximately from  (3.95– 4.99 ) to (5.12–8.11). Organic-C rose about 0.2 to 1 point higher than organic-C of tephra before the leaching experiment. The increasing value of organic-C was predicted to increase CEC (Cation Exchange Capacity) (2.13–5.36 cmolc kg-1). After the leaching experiment, the tephra’s surface was weathered clearly as an impact of solvents and the growing of algae.
