Abstract

A research about effect of soil managment and organic mulch application on soil physical properties of psamment and conr production was conducted in Korong Muaro, Nagari Sunur Kecamatan Nan Sabaris Kabupaten Padang Pariaman, as well as in soil laboratory, Agriculture Faculty, Andalas University Padang.  This research was done from April – October 2009.  The objective of the research was to identify interaction effect between soil cultivation and organic mulch application on chemical properties of psamment and production of sweet corn.  This research was designed in two factors: 3 x 4 with three replications. The first factor was soil cultivation which consisted of 3 levels (Po = No-till, P1 = Minimum tillage, P2 = Conventional till).  The second factor was organic mulch application, which consisted of four levels: Z = without mulch addition, T = Titonia for 8 ton DW/ha, K = Chromolaena for 8 ton DW/ha, J = straw 8 ton DW/ha. The result showed that soil cultivation combined with rice straw mulch application could increase N, P, K elements in soil.  Soil N content increased from 0,17 % to  0,28 %, avail-P from 52,57 ppm to 88,60 ppm, and K-exch from 0,64 me/100g to 2,35 me/100g, however, minimum tillage gave the highest yield which was 7,68 ton weight  of corn seeds + the stalk /hektar, and rice straw mulch showed the highest among the organic mulch applied, which was 8,85 ton/ha.Keywords: Soil cultivation, organic mulch, psamment, sweet corn

Abstract

Utilization of arbuscular mycorrhizae fungi (FMA) is an alternative way to improve soil fertility. Therefore, it must be developed by studying deeply the effectivity of the FMA. This is important due to either its ability to associate with almost all of vegetation family in terrestrial ecosystems or its ability to increase plant growth rate, seedlings quality, and crop yield, especially on critical land. A research about effectivity of variously indigenous arbuscular mycorrhizae fungi on P-sorption and Jatropha growth was conducted at laboratorium and glasshouse Agriculture Faculty, Andalas University. This research was aimed to gain the most effective isolate of arbuscular mycorrhizae fungi on growth of and P-sorption by Jatropha (Jatropha curcas L.) plant on critical land. Single isolat such as Glomus sp2, Acaulospora sp1, Gigaspora sp1, and compound isolate M7 (Glomus sp2,+ Acaulospora sp1 + Gigaspora sp1) significantly affected plant height, canopy dry matter, infection percentage and intensity, and P-sorption. M7 Compound isolate was the most effective innoculum. By this isolate, height of Jatropha seedlings was 27.5 cm, canopy dry matter 5.9 g, infection percentage 78.5%, infection intensity was 49.1, and P-sorption by canopy was 1.6 g for each seedling.

Abstract

A study about sediment content and nutrient movement was conducted in Sumpur watershed, Tanah Datar Regency, West Sumatra. The objective of the research was to determine sediment content and nutrient movement on Sumpur watershed and the relationship. Survey method by sampling water in joining river was employed to this research for sampling water. Water was sampled exactly after rain or at the time of river debit was maximum and without rain as a control. Water flowing into the river comes from several lad uses in the upper watershed. There were four types of land use found in the areas, those were forest, mixed garden, annual season crops, and rice field. Based on field observation it was found that there were two classes of soils there, Andisols and Inceptisols. The results of laboratory analyses showed that river current, soil consentration in river water, as well as sediment content were linearly correlated to rainfall amount. Positive linear correlation was also found between river debit and carried nutrients (N, P, K, Ca, Mg, Na) from the research area. Keywords: watershed, rainfall, sediment carried, and nutrient carried

Abstract

The use of organic fertilizers in agricultural production can not only increase soil fertility but also at the same time improve soil quality. Organic fertilizer is a unique product because it can improve physical properties, chemical, and biological soil as plant growth media. These characteristics bring the organic fertilizers into a valuable product that can be used in a variety of use. Today in Indonesia, there are so many outstanding varieties of organic fertilizer products either refined or imported products. Monitoring of the quality and feasibility of organic fertilizer materials is needed, so they will not harm the farmers as consumers. Each country develops criteria standard of organic fertilizer valuing each country's interest. United States, Canada, Australia and Europe use different compost quality criteria tailored to the needs and environmental rules that apply. So far in Indonesia rules used in determining quality is Permentan No. 02/Pert/HK.060/2/2006 which was then updated with Permentan No.28/PERMENTAN/OT.140/2/2009 on Organic Fertilizers and Soil Ameliorant. Basically, the appraisal made on the maturity and quality of organic fertilizers is based on observation of physical, chemical, and biological parameters. Review of the criteria used in the Regulation of the Minister of Agriculture was necessary in considering the criteria used which are very harmful to consumers, such as if it is satated that C-organic content is approximately 12%, which is low, it means that there might exist some follow-up materials such as glass, plastic in the fertilizer about 2%. If the rules are maintained, it will be very detrimental to Indonesia because of invasion from over seas. Import organic fertilizers would be siege to Indonesian farmers. Permentan No.28/PERMENTAN/SR.130/5/2009 has also set up institutions in charge of monitoring the quality of organic fertilizers. However, the quality control must be carried out. It is not only at the level of the end product, but it must also begin from the moment of the production process by establishing a supervisory agency competent. Since organic fertilizers can be produced by large industries, small and medium-scale farmers, the level of supervision is needed with different approaches. Keywords: organic fertilizer, quality, processes and controls

Abstract

Study on decomposition rate of accumulating and excluder tree species of calsium (Ca) was conducted in a super wet tropical rain forest in Gadut Mountain Padang West Sumatra. The purposes of the study were : (1) to understand the rate of decomposition of biomass of Ca accumulating and excluder tree species, (2) to understand the effect of slope position (ridge, midle and lower slope) on decomposition rate within the study plot and (3) to understand the amount of nutrient release to soil ecosystem within certain period. The result of this study showed that the higher decompoisition rate among two species was Eugenia sp, as Ca accumlating tree species which grew at lower slope. Six months after decomposition, 1 ton dry biomass of Eugenia sp contributed 6,8 kg N, 0,4 kg P, 4,12 kg K, 38,76 kg Ca, and 2,1 kg Mg in to the soil. This amount might keep an equilibrium of soil nutreint balance to support the forest ecosystem. However, for one ton dry mass of Lithocarpus korthalsii sp as Ca exluder tree species, after 6 months decomposition, contributed 9,4 kg N, 1,1 kg P, 4,61 kg K, 3,76 kg Ca and 0,54 kg Mg. This indicates that Ca acumulating tree species contributed more Ca compared to Ca excluder tree species in this forest ecosystem. Keywords: Accumulating tree sp., exluder tree sp., decomposition rate, super wet and tropical rain forest.
