Pengaruh Aplikasi Biokom, Coal Fly-Ash, dan Fungi Pelarut P Terhadap Beberapa Sifat Kimia pada Tanah Gambut yang Ditanami Tanaman Jagung (Zea mays)
No full textAs long as the issues with peat soil, particularly with some of its chemical qualities, can be treated properly, it has the potential to be utilized as agricultural land. Empty oil palm fruit bunches (EFB), which are produced by the size of oil palm farms, can be used to make biochar and EFB compost, which are then combined to create biokom, which can enhance soil structure and increase the availability of phosphorus in peat. Aspergillus oryzae-Tb7 is one of the phosphore solubilizing fungus (FPP) that aid in accelerating the release of accessible P. The byproduct of burning coal in a PLTU that is alkaline by nature and capable of raising soil pH to promote an increase in available P is known as coal fly ash (CFA). The goal of this study's conclusion was to ascertain the impact on the chemical characteristics of maize plants' uptake of P as well as soil pH, CEC, soluble Fe, and available P.A single-component, completely randomized design was used in this study (CRD). The factors A 0, which stood for "control without treatment," A1, "P fertilizer," A2, "P + Biochar fertilizer," A3, "P
+ CFA fertilizer," A4, "P fertilizer + Biokom + FPP," and "P fertilizer + Biokom + CFA + FPP," were tested. There were three repetitions of each therapy, yielding 18 trials. The findings show that the use of biokom, FPP, and CFA can improve P uptake, soil pH, CEC, and soil-accessible P while lowering plant dry weight and soluble Fe

Get PDFThe application of organic matter with a high nitrogen (N) content in combination with the application of wood charcoal is a common soil fertility management practice in Ultisols. This study aims to determine the availability of N in Ultisols, which are applied to swallow droppings and wood charcoal. The experimental design used was a two-factor Completely Randomized Design (CRD), with the first factor being swallow droppings (0.5 and 10 t ha−1) and the second factor being wood charcoal (0, 10, and 20 t ha−1), with as many as three repetitions. As much as 200 g of soil was put into the incubation site, then swallow droppings and wood charcoal were added according to the treatment, stirred until evenly distributed, and then incubated at 70% field capacity for 14 days. The contents of NH4+, NO3-, and pH were observed at the end of the incubation period. The results showed that the application of swallow droppings and wood charcoal increased the content of NH4+, NO3-, and mineral N but lowered soil pH. The best treatment was given to swallow manure at 10 t ha-1 which increased mineral N by 59%, and a combination of swallow manure 10 t ha-1+10 t ha-1 wood charcoal which increased nitrate content by 1,666%. The results of this study indicate that the application of swallow droppings combined with wood charcoal can increase the availability of N in Ultisols.The application of organic matter with a high nitrogen (N) content in combination with the application of wood charcoal is a common soil fertility management practice in Ultisols.
