Abstract

This study is aimed to test the hypothesis that the soil quality of sugarcane plantations closely linked to the particulate organic matter (POM) and earthworm’s populations. The research was conducted at five sites in Malang, East Java. The sites were selected based on differences in average annual rainfall and two types of soil management : with and without organic input. Soil samples taken from a depth of 0-20 cm were analyzed total organic C (TOC), total N, POM-C, and POM-N and earthworm’s population density and biomass. The TOC were corrected by the clay  content using pedotransfer equations so obtained TOCref. The interaction between differences in annual rainfall and two types of the treatments significantly (p

Abstract

Pinang nut (Areca catechu L.) is a major agroforestry crops in Papua with high economic value. This study developed allometric equations for estimating Pinang biomass on the basis of stem diameter and height by destructive sampling inagroforestry systems. Aboveground biomass was measured and linked to plant stem diameter at various heights (0.13 and 130 cm above the ground) and plant height. The resultant equation was used for biomass estimates in various agroforestry systems with Pinang trees, with total of 18 plots differentiated in bottom, middle and upper slope positions. As expected for palm trees, plant height is a better predictor (Y = 0.816 H1.42; R2 = 0.89) of biomass than stem diameter, with equal results for diameter measurements at 13 or 130 cm height (Y = 0.0689 D2.59; R2 = 0.74). Best results were for an equation combining diameter and plant height: Y = 0.03883*H*D1.2; R2 = 0.96. Agroforestry systems on the upper slopes had the highest carbon stocks (38.8 Mg ha-1) than the middle and lower slopes (25.9 and 22.5 Mg ha-1, respectively). Aboveground carbon stocks of Pinang in study area ranged from 0.96 to 20.9 kg C tree-1 with an average of 10.1 kg C tree-1.

Abstract

Post eruption land reclamation consists of hoeing, mixing volcanic ash with soil, adding external organic and/or in-organic fertilizers and making infiltration-pits (‘rorak’). This study, after the 2014 eruption of Kelud volcano, aimed to evaluate: (a) soil physico-chemical fertility post eruption, (b) impact of organic inputs interacting with ash in infiltration pits on soil C and N underneath (1st experiment), (c) biomass loss (decomposition) of local biomass (Trema orientalis and Parasponia andersonii) in a coffee agroforestry system (2nd experiment). Measurements in the ash-affected (+Ash) Tulungrejo-village (Ngantang-Malang district) were contrasted with an area without recent ash deposits (-Ash) in Krisik (Gandusari-Wlingi district). The 1st experiment (-Ash site) treatments did not lead to statistically significant influences on soil conditions just below the infiltration pits during 12 weeks of monitoring. The 2nd experiment quantified rate of biomass loss from litterbags. In +Ash location, litter half-life time (t50) was 19.5 weeks for coffee or Parasponia as single biomass source to 24 weeks for Coffee+Sengon+Durian. In -Ash location decomposition was slower, with t50 of 24 weeks for Parasponia to 27 weeks for Coffee+Sengon+Durian biomass. Concentrations of soil NH4 and NO3 below the litterbags peaked between 4 to 8 weeks, with nitrification lagging behind on ammonium release.

Abstract

Maintaining and where feasible restoring soil carbon stocks is part of all sustainable development strategies that have a chance of meeting the global commitment of the Paris Agreement to contain global warming within a 1.5oC limit. Active policies to incentivize increased soil carbon storage require under­standing of the drivers of soil carbon decline, as well as the conditions under which soil management leads to an increase. Soil carbon transitions -- shifts from decline to increase of soil carbon stocks -- have been recorded as part of agricultural intensification. Organic inputs supporting soil carbon may primarily depend on roots, rather than aboveground inputs, and thus on the choice of crops, trees, and grasses that make up an agricultural land use system.

Abstract

Penanaman pepopohan di lahan pertanian dalam sistem agroforestry dan hutan rakyat diharapkan mampu meningkatkan keberlanjutan lansekap yang dinilai dari aspek ekologi, sosial dan ekonomi. Hal ini dipengaruhi oleh manajemen lahan yang menentukan proses pengambilan keputusan terkait sistem penggunaan lahan yang dipilih dan jenis tanaman yang akan ditanam. Keberadaan pohon dalam sistem hutan rakyat diharapkan mampu memperbaiki produktivitas lahan dan dapat memberikan pendapatan untuk perbaikan dalam aspek ekonomi. Penilaian manfaat ekonomi pohon dalam kurun waktu tertentu dapat dilakukan melalui analisis Net Present Value (NPV). Tujuan dari penelitian ini adalah mengevaluasi keuntungan yang diperoleh petani pada sistem hutan rakyat khususnya tanaman sengon dan jati dibandingkan dengan tanaman semusim (jagung dan bawang merah) serta menganalisis sistem mana yang lebih menguntungkan ditinjau dari aspek ekonomi dan ekologi.Survey dilakukan dengan metode purposive sampling dengan tujuan untuk mendapatkan informasi terkait biaya produksi dan pendapatan dari petani yang benar-benar mengelola sistem hutan rakyat. Penelitian ini dilakukan pada di Kabupaten Malang yang merupakan sentra hutan rakyat di Jawa Timur. Populasi pohon rata-rata pada hutan rakyat adalah 1396 pohon ha-1. Hutan rakyat jati dan sengon, sekitar 77% didominasi oleh kayu sedang (BJ 0,6 – 0,75 g cm-3), dan 23% kayu ringan. Total cadangan karbon di Hutan rakyat jati cukup tinggi bila dibandingkan dengan hutan rakyat sengon. Secara ekonomi, hutan rakyat jati memiliki nilai NPV tertinggi yakni Rp. 643.514.720,-/ha/30 tahun, sedang hutan rakyat sengon sekitar 44% lebih rendah (Rp. 357.833.338,-/ha/30 tahun). Nilai NPV pada hutan rakyat lebih tinggi dibandingkan dengan tanaman semusim sehingga hutan rakyat lebih menguntungkan secara ekonomi dibandingkan tanaman semusim. Secara ekologi hutan rakyat mampu memperbaiki kondisi lahan dan kesuburan tanah secara perlahan melalui masukan seresahnya, serta dapat menekan limpasan permukaan karena tutupan kanopinya dan meningkatkan cadangan karbon

Abstract

Earthworms population in the soil are greatly impacted by agricultural management, yet little is known about how the quality and quantity of organic matter addition interact in sugarcane cropping system to earthworm population. This study describes the effect of various organic matter and application rates on earthworms in sugarcane cropping system. Earthworms were collected in April, July and December from 48 experimental plots under five kinds of organic matter application : (1) cattle manure, (2) filter cake of sugar mill, (3) sugarcane trash, (4) mixture of cattle manure+filter cake, and (5) mixture of cattle manure+sugarcane trash. There were three application rates of the organic matter (5, 10, and 15 ton ha-1). The treatments were arranged in factorial block randomize design with three replications and one treatment as a control (no organic input). Earthworms were collected using monolith sampling methods and hand-sorted from each plot, and measured its density (D) (indiv.m-2), biomass (B) (g m-2) and B/D ratio (g/indiv.). All the plots receiving organic matter input had higher earthworm density, biomass, and B/D ratio than the control. The highest earthworm population density was found in the plot receiving application of sugarcane trash (78 indiv.m-2) and the mixture of cattle manure+sugarcane trash (84 indiv.m-2). The increase in application rates of organic matter could increase the earthworm density and biomass. Earthworm population density also appeared to be strongly influenced by the quality of organic matter, such as the C-organic, N, C/N ratio, lignin, polyphenols, and cellulose content. Earthworm preferred low quality organic matter. It was caused by the higher energy of low quality organic matter than high quality organic matter. Our findings suggest that the input of low quality organic matter with application rate as 10 ton ha-1 is important for maintaining earthworm population and soil health in sugarcane land.Keywords: earthworms, organic matter quantity, quality, sugarcane cropping system

Abstract

Maintaining litter thickness on agricultural land is one of key factor for maintaining diversity of nematode. Litter on soil surface is energy source of decomposer which will be consumed by bacterivore nematode. Higher litter input gives benefit to crop through maintaining diversity of non parasite nematode, improving soil porosity and soil moisture which important to control plant parasite nematode and achieve a sustainable crop production. The research was conducted to study diversity and abundance of nematodes in various landuse system and effect of different soil temperature and water content of various landuse system to nematode`s diversity and it`s abundance. Soil sampling on nine landuse system (degraded forest, bamboo forest, coffee multistrate, Gliricidia shade coffee, mahoghany plantation, pine plantation, Aghatis plantation, grassland and annual crop). Nematodes were extracted by sieving-centrifugation with sugar method. The soil nematodes were grouped into order and generic level including plant parasitic and non-paracitic. The result show that the diversity (number of taksa) and abundance of soil nematode in Konto watershed were high with a total of 44 taksa nematode genera and a total number ranged 334-910 individuals/300 cc of soil. The nematode`s diversity was decreased from 44 genera in degraded forest to 24 genera in Gliricidia shade coffee. The diversity and abundance of nematodes was not linked to variation of water content, but were correlated to plant vegetation and clay content. Diversity of Free-living nematodes was closely correlated with plant diversity (R2 = 0,69) and litter biomass (R2 = 0,32). While plant parasitic nematodes was closely correlated and significant with clay content (R2 = 0,62).Key words: nematodes, diversity, landuse system

Abstract

Forest conversion to coffee agro forestry has decreased quality and amount of litter fall, increase decomposition rate and litter fall mineralization. This research was aimed measuring soil nitrification rate by addition of forest, coffee based agro forestry with mix shade trees and legume-shaded coffee (Gliricidia sepium) and monoculture of coffee litter fall. This research that was conducted in May-June 2005 used Inceptisol  and litter fall of forest, coffee based agro forestry with mix shade trees and legume-shaded coffee (Gliricidia sepium) and monoculture of coffee from Bodong, Sumberjaya, Lampung Barat. Litter fall was collected by litter trap. This research was compiled in a completely randomized design with aerobic incubation method during 8 week in laboratory by 5 treatment addition of forest, coffee based agro forestry with mix shade trees and legume-shaded coffee (Gliricidia sepium), monoculture of coffee litter fall and control (non litter fall addition). Measurement conducted adding litter fall and soil has incubation during 2 weeks. Soil nitrification rate determined by comparing concentration of NH4+ and NO3- after added of litter fall. Data analysis was used one-way. Result of research showed that (1) addition of litter fall has significant (p<0.01) to concentration of NH4+ and NO3- - and N-mineral of soil (2) addition of litter fall has significant (p<0.01) to NH4+ /NO3- ratio (3) addition of coffee monoculture litter fall has yield concentration of NO3- higher than forest and coffee based agro forestry with mix shade trees litter fall (4) addition of coffee monoculture litter fall has yield ratio of NH4+ and NO3- lower (0.1mg kg-1) than addition of forest litter fall (1mg kg-1), coffee based agro forestry with mix shade trees litter fall (0.4mg kg-1) and legume-shaded coffee (Gliricidia sepium) litter fall (0.8mg kg-1). This result of research indicated that adding litter fall like forest, coffee based agro forestry with mix shade trees and legume-shaded coffee (Gliricidia sepium) litter fall can depress soil nitrification rate until 96%.

Abstract

The addition of organic fertilizer into soil increased earthworm growth and its activity and, not only for decomposer group but also for soil digger group (ecosystem engineer).Pontoscolex corethrurus is one of ecosystem engineer group create many channel in soil, so that increased soil porosity and infiltration in soil The objective of this research was to study on N leaching in various biopores condition which formed by earthworm`s activity. Various level of soil porosity and nitrate consentration at controlled condition was obtained from application of  mixture of 3 types of litter (coffee, Gliricidia and durian), N-urea fertilizer and soil digger earthworm (Pontoscolex corethrurus) into soil.  The treatments tested were (1) KO : Control 1 (without worm, N-Organik and N-Anorganik); (2) KCC : Control 2 (added earthworm, without N-Organic and N-inorganic); (3) UREA : (added earthworm + N-inorganic, without N-Organik); (4) KGD : (added earthworm and N-Organic, without N-inorganic); (5) KGDU : (added earthworm + N-inorganic + N-Organic). Each treatment was repeated four times. The biopores formed by earthworm was measured  from the length of soil channel  at 1st, 2nd, 4th, 6th and 8th weeks after treatments (WAP). Measurement on earthworm`s growth was conducted with measuring earthworm`s length, diameter, biomass and casting by the end of treatment (8 WAP). Analysis of nitrate in leachete was done at 2nd, 4th, 6th and 8th  WAP. Result of this research showed that application of N-anorganic only led to more active earthworm rather (83 %) than application of N-organic resulting longer vertical channel formed by earthworm.  However, the increasing the length of vertical channel was not followed by increasing of water percolation. Porosity was related to nitrat leached concentration (R2 = 0.36). Total of leaching was not only influenced by porosity but also by another factor like NO3- -available (influence by N source input). Application of N-anorganic increased concentration of leached NO3- (42 %) than application of N-organic (181 mg L-1 concentration of leached NO3-). No significant (p>0.05) correlation between soil porosity and earthworm`s biomass was found.

Abstract

Forest conversion to agriculture systems leads to change on litter input (quantitatively and qualitatively) resulting lower diversity, population density and biomass of earthworm. Litter with ratio C/N <20, or ratio of (lignin (L)+polifenol (P))/N <10 classified as high quality which decomposed rapidly. Six types of litter application were tested i.e. prunning of cofee with the lowest (L+P)/N of 7.5, Gliricidia (L+P)/N of 10, avocado with (L+P)/N of 31, Cofee+Gliricidia with (L+P)/N of 12, Cofee+Gliricidia+ avocado with the highest (L+P)/N of 64. As control soil without litter application was used. Applying tree litters regardless their quality increased significantly (p<0.05) all growth parameters of earthworm, except for Gliricidia application lead to higher level of earthworm mortality starting at 20 days after treatment. Applied a low quality of avocado litter to the soil produced the highest biomass (0.79 g/indiv.), diameter (2.42 mm/indiv.) and length (6.13 cm/indiv.). Mixing coffee litter with Gliricidia litter increased earthworm mortality (5.5% to 42.5%) and reduced production of cocoon (2 become 0 cocoons) compared to coffee applied alone. Coffee+Gliricidia+Avocado lead to longer live earthworm up to 80 days Apparently Gliricidia litter producing chemical substances which harmful to earthworm.Keyword: earthworm, litter quality, forest conversion
