PENGARUH PUPUK ORGANIK CAIR DARI LIMBAH CAIR PABRIK TAHU TERHADAP SIFAT FISIK TANAH PADA TANAMAN PAKCOY (BRASSICA RAPA L.) DI ULTISOL
Productivity in ultisols is not only determined by mineral content, but is also influenced by the physical properties of the soil. Soil physical properties are soil properties that are determined by its constituent materials such as water content, bulk density, total pore space and permeability. The purpose of this study was to determine the effect of the application of liquid organic fertilizer from tofu factory liquid waste on the physical properties of soil in pakcoy plants (Brassica rapa L.) in ultisols and to find out the best dosage of liquid organic fertilizer tofu factory liquid waste to improve soil physical properties in pakcoy plants. (Brassica rapa L.) in ultisols. This research was conducted in the greenhouse of the Department of Soil, Faculty of Agriculture, Sriwijaya Indralaya University. Analysis of physical properties was carried out at the Physics, Conservation, Survey and Evaluation Laboratory of the Department of Soil, Faculty of Agriculture, Sriwijaya University. The time for conducting this research was from July to September 2022. This research was designed using a Completely Randomized Design (CRD) with 6 treatment levels. Each treatment was repeated 4 times, so there were 24 experimental units. The results showed that POC treatment had a significant effect on bulk density, total pore space, and permeability and had no significant effect on moisture content in field capacity of pakcoy plants in ultisols. The highest value obtained in the POC treatment was at a dose of 250 ml which had a field capacity water content value of 29.63%, bulk density 0.95 g/〖cm〗^3, total pore space of 64.00% and soil permeability of 11.56 cm/hour. The results of this study suggest that it is better to apply POC to pakcoy plants using a dose of 50 ml with a single fertilizer combination of N, P, K because it is proven to improve the physical properties of ultisols.
