Abstract

Organosol soil has a very high content, but has a low soil acidity (pH) (acidic). As well as the occurrence of very slow decomposition of organic matter. The treatment with Ananas comosus (L.) Merr. extract, which contains bioactive compounds such as bromelain enzymes, organic acids, and simple sugars, can accelerate the decomposition of organic matter and support the activity of soil microorganisms. The Local Microorganisms (MoL) applied, such as Solanum lycopersicum (L.) and Saccharum officinarum Linn., contain various functional microbes such as Lactobacillus sp., Saccharomyces sp., and Azotobacter sp., which play a role in nitrogen fixation, phosphate solubilisation, and organic matter decomposition. Overall, the results of research and observations conducted on Organosol soil media treated with Ananas comosus (L.) Merr. extract with the addition of Local Microorganisms (MoL) Solanum lycopersicum (L.) and Saccharum officinarum Linn. has been proven to effectively improve the chemical properties and fertility of Organosol soil through its role in increasing microbial activity and accelerating the decomposition of organic matter. This indicates that innovations in the application of fruit and the role of local microorganisms have the potential to be developed as environmentally friendly technologies for sustainable soil management.

Abstract

Soil Ameliorants are materials used to improve soil, playing a key role in rehabilitating and enhancing the physical, chemical and biological properties of the soil. In the Organosol soil under study—commonly referred to as Histosol or Peat soil—the soil-improving materials play a vital role, as this soil is highly acidic, has very low levels of macro- and micro-nutrients, and contains organic acids that can be toxic to plants. The distribution of nutrients studied in Organosol soil shows a concentration of organic matter in the upper layer of the Organosol, where abundant nitrogen is bound organically; however, phosphorus, potassium, calcium and magnesium are very low due to leaching processes. In this study, the application of organic matter that supports microbial activity in Organosol soil—specifically the application of oil palm frond ash—can increase potassium (K) levels and soil acidity (pH), whilst the application of soil ameliorants can improve nutrient deficiencies in phosphorus (P), potassium (K), calcium (Ca), and magnesium (Mg), demonstrating a significant and pronounced effect when applied to Organosol soil.
