The Study on Addition of Nutrient Pillar of Nitrogen, Phosphorus, Potassium (N:P:K) and Organic Materials in Organic Fertilizer Which is Decomposed by Using Earthworms (Pheretima peguana)

摘要

The study on addition of nutrient pillar of Nitrogen, Phosphorus, Potassium (N:P:K) and organic materials in organic fertilizer which is decomposed by using earthworms (Pheretima peguana) can be classified the study into 5 sets of experiment as following: Experimental set T1: was an earthworms (P. peguana) habitat controller used soil and animals dung in the proportion of 10:0 kg and also used earthworms (P. peguana) in the amount of 0.5 kg to consume an added molasses organic waste from vegetable in the proportion of 1:15 kg mg-1. Experimental set T2: was an earthworms (P. peguana) habitat used soil and animals dung in the proportion of 10:1 kg and also used earthworms (P. peguana) in the amount of 0.5 kg to consume an added molasses organic waste from vegetable in the proportion of 1:15 kg mg-1. Experimental set T3 was an earthworms (P. peguana) habitat used soil and animals dung in the proportion of 10:3 kg and also used earthworms (P. peguana) in the amount of 0.5 kg to consume an added molasses organic waste from vegetable in the proportion of 1:15 kg mg-1. Experimental set T4 was an earthworms (P. peguana) habitat, used soil and animals dung in the proportion of 10:5 kg and also used earthworms (P. peguana) in the amount of 0.5 kg to consume an added molasses organic waste from vegetable in the proportion of 1:15 kg mg-1. Experimental set T5: was an earthworms (P. peguana) habitat used soil and animals dung in the proportion of 10:7 kg and also used earthworms (P. peguana) in the amount of 0.5 kg to consume an added molasses organic waste from vegetable in the proportion of 1:15 kg mg-1. The study has found that the organic fertilizer which was decomposed by using earthworms (P. peguana), when mixing animals dung (chicken, pig and cow dung) with soil in order to be an earthworms (P. peguana) habitat that would cause the said organic fertilizer has nutrient pillar (N:P:K) and organic materials more proportionally of compost that was mixing with soil in order to be an earthworms (P. peguana) habitat. When the all 5 experimental sets have been brought. A nutrient pillar (N:P:K) and quantity of organic materials in the organic fertilizer that was caused by using earthworms (P. peguana) to decomposing. There was a found that the experimental set 5 has quantities of nutrient phosphorus, potassium and organic materials which the organic materials has the most quantity and as well has an over standard value on 2005 organic fertilizer, for the experimental sets 4, 3, 2 and 1 have orderly nitrogen phosphorus potassium and organic materials.
