Pengaruh Pupuk Kandang, Zeolit, dan Skim Lateks Terhadap Berbagai Sifat Fisik Tanah Latosol Darmaga

Abstract

Latosol Darmaga formed in areas with precipitation more than 3000 mm/year and high temperatures which can result in soil erosion by the raindrop impacts that can damage the soil physical properties. Therefore, the action needs to be done that can improve the physical properties of soil. Improving the physical properties of soil can be done with the addition of manure, zeolites, and skim latex. The purpose of this research is to study the influence of the addition manure, the mineral zeolite, skim latex, and there combinations to changes some soil physical properties of Latosol Darmaga and corn production. Research conducted at the Cikabayan garden and Soil and Water Conservation Laboratory since February 2007 until August 2007. The treatment given is A (control), B (manure), C (zeolite), D (manure + zeolite), E (manure + skim latex), F (zeolite + skim latex), and G (manure+zeolit + skim latex). The dose given was 4.5 kg / plot. The results showed that bulk density after the manure, zeolites, skim latex and there combination showed an increase, aggregate stability of treatments G (manure + zeolite + skim latex) significantly more stable compared with treatment A (control), B (manure) , C (zeolite), D (manure + zeolite), E (manure + skim latex), and F (zeolite + skim latex) in the amount of 58.83. Fast drainage pores in treatment B (manure) more high significantly than A (control) and treatment D (manure + zeolite). The addition of manure, zeolites, skim latex and there combination tends to increase the number of slow drainage pores, available water pores and the mean weight diameter (MWD) of 4.76 mm, while the mean weight diameter (MWD) 2.83 mm was decreased. From this research, suggested that addition soil conditioner to the good soil physical properties need to be done in order to conserve the land to avoid degradation.
