Abstract

Title : Runoff, Erosion and Nutrient Sediment due Vegetative Soil Conservation Applied on Oil Palm Plantation. Land cover crops play an important role in influencing erosion. Cover crops provide protection against the destruction of soil aggregates by rain and runoff. This research aims to study the effectiveness of vegetation as soil conservation in controlling erosion and runoff. This study was a field experiment on erosion plots measuring 10 m x 5 m were arranged in Split Plot design with replications as blocks, consists of a combination of two factors: the age of the oil palm and slope as the first factor, and vegetative soil conservation techniques as a second factor. The results showed the soil conservation techniques in oil palm cultivation can reduce the rate of surface runoff, soil erosion and nutrient loss. Soil conservation with upland rice planted with soybean sequence + strip Mucuna bracteata  (T3) most effectively reduce runoff and prevent soil erosion and nutrient loss.

Abstract

The impact of Volcanic Ash of Kelud Eruption and Manure on Availability and Magnesium Uptake of Corn in Alfisols. Impact of fresh volcanic ash on soil fertility is rarely studied mainly on nutrient availability, uptake and on plant growth. Fresh volcanic ash is primary mineral that takes time and agents such as organic materials to mineralized before it contribute to soil fertility. This study aimed to study the effect of the thickness of fresh volcanic ash of Kelud Mountain and dosage of manure on availability and uptake of Magnesium and chlorophyll content of corn in Alfisol. This is greenhouse experiment arranged in factorial completely randomized design with two treatment. The first factor is the thickness of volcanic ash: 0, 2. 4, and 6 cm, and the second factor is the dosage of manure: 0, 2 and 4 tonha-1, each treatment combination was repeated 3 times. Variables observed include exchangable-Mg , Mg uptake, and chlorophyll content of corn. The results showed that there is no interaction effect of volcanic ash and manure on exchangable-Mg, Mg uptake and chlorophyll content of corn. This proved that they affect nutrient availability in different ways. Both volcanic ash of Kelud eruptionas as well as manure increase exchangable-Mg, especially at 6 cm thickness of volcanic ash treatment, Mg-uptake and  chlorophyll content of corn leaf independently. There was a relationship between exchangable-Mg and chlorophyll content in the leaves.

Abstract

Title : Determination of Soil Quality Index Based on Soil Chemical Properties at The Upstream of Bengawan Solo River Basin Wonogiri. Land conversion extended to the upper of the watershed for residential and agricultural so soil’s ability is decreased to support the soil quality. To solve these problems, in the region upstream of Bengawan Solo, enforced by Agroforestry plantings. Research carried out at the upstream of Bengawan Solo Wonogiri and Laboratory of Chemistry and Fertility of Soil Faculty of Agriculture, Sebelas Maret University Surakarta, in June 2013 until March 2014. Research used a survey method by descriptive and exploratory. Determination of the location of the site sample is done by a stratified random sampling based onland map unit. Sampling was done by a purposive sampling method. The soil quality index is determined by summing the scores for each variable which has selected from Principal Component Analysis (PCA), and then it multiplied by the weight index. The result of the study show that the soil quality of Agroforestry in the upstream of Bengawan Solo Wonogiri based on the chemical properties of the soil is low. The value of soil quality index in the secondary forest is 2.6. While in the Agrosilvopastoral is 2.3 and in the Agrisilviculture is 2.1, which are lower than the secondary forest. Whereas in the Silvopastoral is 3.0, which is higher than the secondary forest.

Abstract

Title : The Balance of Organic and Inorganic Fertilizers to Limiting Factors Nutrient, Soil Fertility and  Maize (Zea mays L) Yield on  Paddy Soil of C-Excavation. The activities for other purposes in the paddy soil will cause soil damage and reduce the values of soil productivity. The use of organic fertilizer is one of efforts to recover and rehabilitate the soil, because it is the key to improve its properties. The purposes of this research were to identify the characteristics of the soil (chemical) as a component of soil fertility, nutrition limiting factors and knowing the balance of organic and inorganic fertilizers on the optimum cultivation of maize (Zea mays L) to achieve maximum production. Research was conducted by using Randomized Complete Block Design (RCBD) with single factor: consisting of six treatments, as follows consisted of control, treatment of inorganic fertilizer as recommended, organic fertilizer (manure), and the balance between organic and inorganic fertilizers. The results showed that the balance between organic and inorganic fertilizers can increase nutrition limiting factors (N and P) and soil fertility in paddy soil of C-excavation. It has been proved by the increasing growth and yield of maize, such as plant height, fresh and dry weight of plant, weight and girth of cob. The highest yield of maize was shown in weight cobs per plant, i.e 190 g as shown in the treatment of the balance between organic and inorganic fertilizers (75: 25)%. It is significantly different than the control treatment, however it showed no significant difference with other treatments.
