Pembenahan Sifat Fisika Tanah Entisol Dengan Perlakuan Kompos

Abstract

SERA PITA LOKA : Revamping the physical properties of Entisol soil with compost treatment. Supervised by SUMONO and DELIMA LAILAN SARI NASUTION. Physical characteristic of Entisol soil is an important factor for the growth of plant. The objective of this research was to know the effect of compost application on physical characteristics of Entisol soil. The design used was completely randomized design consist of 6 (six) treatments and 3 replications that is K1= 10 kg Entisol soil without compost, K2= 9 Kg Entisol soil + 1 kg compost, K3= 8 kg Entisol soil + 2 kg compost, K4= 7 kg Entisol soil + 3 kg compost, K5= 6 kg Entisol soil + 4 kg compost and K6= 5 kg Entisol soil + 5 kg compost . The observed parameters were soil texture, soil organic matter, soil thickness, porosity, soil pore size, soil permeability and water availability. The results showed that the soil type was Entisol with loam sandy texture, soil organic matter was from 0,74 to 4,69%, soil thickness was from 13,83 to 20,16 cm, porosity was from 16 to 37 % , soil pore size was from 2,859 to 5,493 µm, permeability was from 1,24 to 5,64 cm/jam and water availability was from 6,67 to 9,12%.
