Abstract

Slurry is by product of stone process, as cutting and polishing of natural stone. The consequence of the exixtence of slurry can be seen on irrigation water quality and degraded soil such sufficient nutrient and soil physics properties. The aims of this research was to analyse the effect of soil amandment on degraded soil to improve growth of Pakcoy (Brassica rapa L.). This research was conducted in June to August 2024 in Dukuhpuntang Cirebon using the Completely Randomized Design (CRD). The treatments are combination of the rice straw compost and soil affected by natural stone waste as planting media, including: A0 (control 100% soil affected by natural stone waste), A1 (25% soil affected by natural stone waste: 75% rice straw compost), A2 (50% soil affected by natural stone waste: 50% rice straw compost), A3 (75% soil affected by natural stone waste: 25% rice straw compost). Each combination treatment repeated 6 times. The research show that the utilization of rice straw compost in soil affected by natural stone waste as planting media increasing number of plant height, number of leaves, and fresh weight consumption by 41%, 39%, and 83%. Soil amendment improving the soil properties through ideal condition for plant growth, including reducing the soil compaction.

Abstract

Rock flour (slurry), a by-product of the stone industry, contributes to soil degradation by causing soil compaction and reducing soil fertility. The sustainable strategies such as the application of organic amendments are needed to restore soil properties. The aim of this research to evaluate the effects of different organic amendments—rice husk biochar, straw compost, and goat manure—on the growth and yield of pakchoy (Brassica rapa L.) cultivated in stone waste–contaminated soil. This research used randomized block design with four treatments and five replications was employed: (P1) control (stone waste–contaminated soil without amendment), (P2) Stone waste–contaminated soil and husk biochar (1:1), (P3): Stone waste–contaminated soil and straw compost (1:1), and (P4): Stone waste–contaminated soil and goat manure (1;1). The results showed that goat manure significantly enhanced pakchoy growth parameters, including plant height, number of leaves, root volume, and plant weight. Goat manure promote the optimal plant growth through serve optimal planting media.
