Changes in soil chemical properties due to the application of young coconut waste biochar and goat manure fertilizer on tomato (Solanum lycopersicum l.) cultivation land

Abstract

This study aims to determine the effect of young coconut waste biochar and goat manure application on the chemical properties of the entisol. The Biochar Research Station, Universitas Syiah Kuala, conducted the research. This study used a factorial randomized block design consisting of two factors. The first factor was the dose of young coconut waste biochar (0, 5, and 10 t ha-1), and the second was the dose of goat manure (0, 5, 10, and 15 t ha-1). Parameters observed in this study were soil chemical properties analysis of entisol (pH, organic C, total N, available P, and exchangeable K). The results showed that the young coconut waste biochar application could affect the soil’s chemical properties, especially the soil exchangeable K. Young coconut waste biochar application can increase the exchangeable soil K in tomato cultivation land. The application of goat manure did not affect the soil’s chemical properties in tomato cultivation land.
