Abstract

As 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.

Abstract

Rubber plant productivity is often hampered because the availability of nutrients in the soil is not sufficient for plant needs. Some rubber productivity results in Karang Intan Village only reach 1,500-2,000 kg.ha-1.th-1 and some reach 2,000-3,000 kg.ha-1.th-1. Generally, the maximum yield of superior latex clones reaches 2,500-3,000 kg.ha-1.th-1. Given this background, it is necessary to conduct this research with the aim of knowing the status of N, P and K nutrients at location A (low productivity) and location B (high productivity). This research was carried out from July to September 2021. Sampling used in this research was purposive sampling method, sampling was conductedin Karang Intan Village, Kuranji District, analyzed of soil sample was at the Soil Physics and Chemistry Laboratory, Department of Soil, Faculty of Agriculture, Lambung Mangkurat University, after that the data obtained from the results of the analysis categorized the level of fertility. The results showed that the Total-N, Total-P, Available-P, Total-K, Available-K in Locations A and B were not significant (Ortogonal Contrast Anova) so that these nutrients could not be used as factors that caused differences in rubber plant productivity. Ammonium and nitrate in Location B is higher than Location A, the difference in these values ​​is a factor that causes differences in the productivity of rubber plants in Karang Itan Village, Kuranji District.

Abstract

Ultisol is one type of land in Indonesia that has an area distribution of about 25% of Indonesia's total land area and the widest distribution is in Kalimantan (21.938.000 ha). The acidic pH of the soil causes low availability of P in Ultisol and the occurrence of P fixation by Al and Fe which are positively charged, making P difficult to be available to plants. In this study, ameliorant was added in the form of dolomite and chicken manure to see the effect on Ultisol soil by isothermal phosphate absorption analysis and processed using the Langmuir, Freundlich, and Brunauer-Emmett-Teller (BET) equations. The results of the study concluded that the application of P on Ultisol soil in Gunung Kupang Village, Cempaka District, Banjarbaru City, was in accordance with the Freundlich Equation. High or low P absorption indicates the level of P availability in the soil. In other words, fixation on acidic mineral soils can reduce the amount of P available to Plants.
