Analysis of Nutrients (N,P,K) in Bio Seeding Block Based on Sugarcane Waste

Abstract

Macronutrients are very important in plants, because they have a significant role in the development of lants and very required to fulfill. Nitrogen, Potassium, and also Phosphorus are three important macronutrients. Bio seeding block is a seeding media made by soil block, it consists of a sugarcane waste. It is good for an environment, sensible, and rich in natural matters. The aims in this research, is to analyze the nutrient composition in bio seeding block. Bio seeding block products used waste from sugarcane, that consisted of bagasse, sugarcane filter cake, and ash from sugarcane. There are 4 treatments to analyze bio seeding block such as : Treatment A, with ratio between sugarcane filter cake : bagasse : and ash are 4 : 4 : 1, treatment B, with ratio are 5 : 3 : 1, treatment C, with ratio are 6 : 2 : 1, and treatment D, with ratio 7 : 1 : 1. The results show that the highest amount of N is in treatment D that is 0,439; the highest amount of P is in treatment B that is 2,170; and the highest amount of K is in treatment A that is 0,480. Based on plant growth tests (plant height, leaf width, and stem diameter) show that medium A is the fastest growing medium in the first 15 days and also has high number of main nutrients.
