Abstract

Ultisol has problems such as soil acidity <5.5, high Al saturation >42%, low organic matter <1.15%, low nutrients such as 0.14% N, P 5.80 ppm, and low base saturation < 35%. Chicken manure is an organic material that alters soil pH and increases total N, total P, and P uptake. Coffee grounds can increase pH, N nutrients, organic matter, available P, prevent fungal growth. The purpose of this study was to determine the effects of feeding chicken manure and coffee grounds compost extract in increasing pH, increasing N availability, decreasing exchangeable Al, and increasing P availability of Ultisol. The research method used was a one-factor Completely Randomized Design (CRD). Factors tested were chicken manure, coffee grounds compost extract, and a combination of the two up to five treatments. K0 = Control, no chicken manure and coffee grounds compost extract; K1 = Coffee grounds compost extract 4 kL ha-1; K2 = Chicken manure 2 tons ha-1; K3 = Chicken manure 2 tons ha-1 + coffee grounds compost extract 4 kL ha-1; K4 = Chicken manure 4 tons ha-1 + coffee grounds compost extract 8 kL ha-1. Each treatment was replicated four times for 20 experiments. The results showed that the application of chicken manure and coffee grounds compost extract decreased soil pH, and soil exchangeable Al and increased soil ammonium, nitrate and available P levels.

Abstract

Ultisols is an acid mineral soil that has various problems namely high soil acidity, Al3+ concentration and nutrient poor. One way to increase soil fertility and quality is by using ameliorant. Palm oil waste can be used to make ameliorant. Palm oil decanter cake and palm oil boiler ash are the types of palm oil waste used in this research. Providing Palm oil decanter cake and palm oil boiler ash can increase pH, available N-mineral, P concentration, and K-dd in Ultisols. The aim of this research is to determine the effect of providing waste decanter solid and palm oil boiler ash on changes in several chemical properties of Ultisols soil and the best combination of palm oil solid waste (decanter solid) and palm oil boiler ash to improve several soil chemical properties, namely, pH, availability of nitrogen, phosphorus and potassium in Ultisols soil. This research used a Completely Randomized Design Method factorial with two factors, the first factor being a Palm oil decanter cake (0, 5, and 10 t ha-1) and the second factor is palm oil boiler ash (0, 5, and 10 t ha-1), with three repetitions. This research was carried out in a greenhouse and analyzed in a soil physics, chemistry and biology laboratory. The research results show a combination of Palm oil decanter cake and palm oil boiler ash have a significant effect on pH, N-mineral concentration, and available P and palm oil boiler ash itself can increase the concentration of K-dd.
