Abstract

Title : The Degree of Erosion Hazard Mapping in Dry Land at Jatipuro Sub District of Karanganyar with Geographic Information System (GIS). This research had been conducted at Jatipuro, Sub District of Karanganyar from July until September, 2007. The aims of this research are to know degree of erosion danger and to map that degree of erosion danger. This research was descriptive-explorative by field’s survey and laboratory analysis. Soil sampling technique using purposive sampling method. Site sampling determined with land mapping unit. Analysis of erosion level using USLE method, even though to know degree of erosion dangerous used the table of relation soil depth with erosion level. To make the map degree of erosion dangerous with Arc view GIS 3.3 software. The result of this research conclude that Jatipuro, Sub District of Karanganyar can be classified into 4 erosion dangerous class, with position and width area such that very light in 6th land mapping unit with width area 8.53 ha or 1.17% from total wide of research area. Light, in 1st, 4th, 7th, 12tnd and 16th land mapping units with width area 245.36 ha or 33.72% from total wide of research area. Middle class, in 2nd, 8th, 9th, 10th, 14th, 15th, 17th and 18th land mapping units with width area 181.59 ha or 24.95% from total wide area. Heavy class, in 3rd, 5th, 11th, 13th, 19th, 20th, 21st and 22nd land mapping units with width area 292.18 ha or 40.15% from total wide area. The management of conservation in the land with degree of erosion danger very light until light is low tillage applications, which this purpose is to create soil condition that supported growth of root, but also must be understood the result of tillage, which can be broken soil structures. For the lands with degree of erosion danger middle until heavy, the better conservation is needed. These lands needed terrace’s repairing, there are making bench terrace with middle construction for the middle class and more better terrace for the heavy one. For the best result to minimalist erosion level in this location, in terrace’s making also needed vegetative conservation, there is strip grass to strength the terrace, and also mulching.

Abstract

Peanuts cultivation in alfisols dryland limited by low levels of soil fertility. An agricultural intensification that could be done is application of organic and inorganic fertilizer. This research aimed to study the balance of N, P, and manure fertilizer dosage on growth and yield of peanuts in alfisols dryland. The research was done in April 2014 - September 2014 in Sukosari, Jumantono, Karanganyar. This research was compiled using a Randomized Completely Block Design (RCBD) factorial with three factors, there are dose of urea, SP-36 and cow manure fertilizer. The results showed that the dose combinations of urea, SP-36, and cow manure fertilizer have no interaction affected all of variable plant. The application of 300 kg ha-1 SP-36 fertilizer increased the number of pods and weight of pods, while the weight of 1000 seeds was improved by application of 150 kg ha-1 urea fertilizer.

Abstract

Title : Intercropping and Livestock Integration System : Changes in Physical and Chemical Properties of Litosol. Study sites located in the village Geneng duwur, District Gemolong, Sragen regency, Central Java with litosol soil type. Study sites are located between 7 º 23'10 "latitude and 7 º 23'17" latitude and 110 º 50'28 "E to 110 º 50'24" E with altitude between 150 masl to 155 masl. The experiment was conducted in February 2010 to November 2010. The purpose of the study: (1) Knowing the integrated effect of intercropping with cattle on soil physical properties, (2) Knowing the effect of intercropping systems are integrated with livestock on soil chemical properties. The study design used in this study is complete randomized block design consisting of two factors: factor 1: integration of cattle consisting of 4 standard (I0 = no cattle integration (0 years); I1 = 1 year of integration of cattle ; I2 = integration of cattle 2 years; I3 = integration of cattle 3 years) and factor 2: cropping system consisting of a 3 stage (K = monoculture cropping systems with groundnut crop; J = monoculture cropping systems with corn; KJ = cropping system intercropped with maize crop peanuts). Research results indicate that: (1) intercropping system does not significantly affect the improvement of soil physical properties include: soil density, volume weight of soil, field capacity, porosity; integration of livestock significantly affect the improvement of soil physical properties include: density of the soil, volume weight of soil, field capacity and soil porosity, (2) intercropping system did not significantly affect the chemical properties of soil improvement which include: soil organic matter, total soil N and soil pH; integration of livestock significantly affect the chemical properties of soil improvement material covering soil organic matter, total soil N and soil pH.
