Abstract

The water content of the soil in Jatikerto is 32,02%. As it is supported by clayey loam soil texture, the soil is able to absorb more water, but the water in the soil cannot necessarily be available to the plants. One effort to maintain the availability of ground water can be done with the soil amendments materials such as biochar. This study used three types of biochar, i.e. rice husk, coconut shell, and wood with each contained three doses (15, 30 and 45 t ha-1). This study used ten treatments with two factors consisted of types and doses of biochar. Soil sampling was conducted at 2 points on the array and on an array, and each point was conducted on soil depth of 0-20 cm and 20-40 cm. The variables measured were soil texture, soil bulk density, soil porosity, pore space distribution, pore fast drainage, pore slow drainage and pores water available. The results indicated that treatments of types and doses of biochar did not change the texture of the soil. The highest soil bulk density contained in biochar types of wood biochar dose of 30 t ha-1 (1,20 g cm-3), while for soil particle density was not significantly influenced by the biochar treatments. The average value of the highest porosity was measured on the type of wood biochar dose 15 t ha-1 (47,54% vol). The highest pore fast drainage contained in biochar types of coconut shell biochar dose of 30 t ha-1 (20,80% vol), while for the highest available pore water was on the type of coconut shell biochar dose 45 t ha-1(21,55% vol). The highest pore slow drainage was on the type of wood biochar dose 30 t ha-1 (29,03% vol).

Abstract

Based on data from Malang District in 2015, Pakisaji has the potential to reach 17,000 tons of rice yield. However, it has some hindrance in water availability that affects rice planting planted using conventional methods. One of the rice cropping system that can be used to reduce water usage is SRI (System of Rice Intensification) method. The goal of this study was to know the content change of  soil N, P, K due to application of NPK 15-15-15 fertilizer combined with biofertilizer using SRI method and determine the level of crop production. The results of this study showed that the application of NPK 15-15-15 fertilizer combined with biofertilizer in SRI method produced the highest soil nutrient content such as total nitrogen (0.29%), P availability (26.31 ppm), and K availability (0.58 me 100 g-1 especially at the depth of 0-20 cm. The combination of NPK 15-15-15 fertilizer and biofertilizer applied in SRI method obtained the highest yield at a weight of 1000 seeds (30.31 g) and yield of dry grain harvest (8.4 t ha-1).

Abstract

NPK fertilizer residue can positively affect the improvement of soil nutrients and increase crop production, but the negative impact to the soil and plant growth can also be caused by fertilizer unmanaged NPK fertilizer. The aim of this study was to determine the residual effect of NPK fertilizer based combination of ammonium nitrate and NPK petrobiofertile on availability of nutrients in the second cropping season. Treatment tested were residue of 400 kg ha-1 of NPK 25-7-7 with additional nitrate as much as 1%, 2% and 3% and fertilizer combinations Petrobiofertil 100 kg ha-1. Results showed that the treatments significantly affected the content of mineral N at 20 days after planting at a depth of 0-20 cm and at 40 days after planting at 0-20 cm and 20-40 cm depths,  but the results were not significant at a depth of 20-40 cm at 20 days after planting. N concentration at 40 days after planting at a depth of 0-20 cm was significantly different high at P4 treatment. Concentrations of total K was significant at 20 days after planting at a depth of 0-20 cm and 20-40 cm and at 40 days after planting at 20-40 cm depth. The treatments also results in a significant number of bacterial colonies on 20 days after planting and 40 days after planting. Plant height, leaf number, leaf area, fresh consumption significant weight at 20 until 40 days after planting. N uptake was also significant at 20 and 40 days after planting

Abstract

Nitrogen is needed by plants in a sufficient level. This study was aimed to understand the influence of NPK Kebomas ammonium and nitrate based 25-7-7 combined with Petrobiofertil fertilizer on soil chemical properties and common bean production. Treatments tested in this study were P0 (control), P1-P4 (NPK 25-7-7 + nitrate 0-3%), P5-P8 (NPK 25-7-7 + nitrate 0-3% + Petrobiofertil). The nine treatments were arranged in a randomized block design with three replicates. The results showed that application of NPK fertilizer 25-7-7 combined with Petrobiofertil fertilizer gave significant effects on nitrogen, ammonium, nitrate, phosphorus, potassium and pH of the soil studied. The addition of fertilizer (NPK 25-7-7 + Nitrate 3%) + Petrobiofertil affected plant weights, weight of pods, weight of seeds, weight of skins and the number of pods were higher than other treatments

Abstract

The development of forest plantations into one of forestry enterprises is seen as an activity that can reduce emissions by increasing carbon stocks. Measurement of carbon stocks needs to be done to obtain data of carbon stocks stored in a field so that it can be calculated emissions that are released into the atmosphere when there is a fraction of the land cover. In this study, carbon stocks was calculated by estimation method using allometric equations that had been made in previous studies and devoted to the stands of teak (Tectona grandis Linn. F), litter and soil. The study was conducted by dividing the teak plantation with various age classes (KU) of teak plant, ranging from KU 1 to KU 6. KU 1 has age 1 - 10 years, KU 2 has age 11-20 years, KU 3 has age 21 - 30 years old, KU 4 has age 31 - 40 years old, KU 5 has age 41-50 years and KU 6 has age 51 - 60 years old. The value of carbon stocks in the teak stands in each equation increased with the increasing age of the teak stand. Carbon deposits in teak forests increased by 3.96 t ha-1 to 5.54 t ha-1 annually. Teak forests can reduce CO2 in the air, and the greater the age of teak the greater CO2 in the air can be reduced. Teak forests can reduce CO2 in the air by 14.45 t ha-1 to 20.26 t ha-1 annually. Basal area value on teak stands affects 64% of litter biomass values. The higher the basal area value the litter biomass value will increase. Basal area values of teak forests in KU 1 to KU 6 ranged from 5.63 m² ha-1 to 50.36 m² ha-1.

Abstract

Biofertilizer applications are needed to improve soil quality such as soil productivity and increasing the efficiency of the fertilization. Availability of nutrients in the soil is affected by microbes found in the soil. Soil microbes reproduce themselves and active in supplying nutrients to plants by releasing nutrients that are bound to be available to plants. The aim of this research was to observe and analyze the effect of biofertilizer on sugarcane growth and its effect on the population of potassium solubilizing bacteria. Results showed that The application of basic fertilizer combined with biofertilizer has a significant effect on the growth of sugarcane both in plant height and diameter of the stem. In the parameters of plant height, the best treatment was A5 which was a combination of anorganic fertilizer + 200% biofertilizer same as the other plant growth parameter which was stem diameter. Then on the production parameters, fresh plant weight and root weight, best treatment was A5. As for the parameters of potassium solubilizing bacteria, the best treatment that increased population was treatment A4 which was basic fertilizer combined with 150% biofertilizers. In total soil bacteria, the various application doses of biofertilizers did not have a significant effect. However, there was an increase of 0,49% in treatment A5 (basic fertilizer+200% biological fertilizer) compared to control (A1). The application of biofertilizer also did not have a significant effect on the parameters of organic matter and soil water content
