An Improvement of Yasothon Soil Fertility (Oxic Paleustults) Using Municipal Fermented Organic Compost and Panicum maximum TD 58 Grass
T. Chuasavathi,V. Trelo-ges
Pakistan Journal of Biological Sciences , 2001,
Abstract: An investigation on the improvement of Yasothon soil (Oxic Paleustults) fertility by Khon Kaen`s municipal fermented waste was carried out at Khon Kaen University for the treatments with and without sowing Panicum maximum TD 58 grass. The results showed that Khon Kaen`s municipal waste had a tremendous effect in improving Yasothon soil fertility. Decomposition rate of organic compost in soil was most rapid due to high environmental temperature. The improvement of soil fertility was greater for treatments with the growth of Panicum maximum TD 58 grass than those without. An increase in the amount of organic compost added to the soil increased the percentages of soil nitrogen, soil available P and exchangeable K. Municipal organic compost increased soil pH, but a greater result was found for treatments with the growth of Panicum maximum TD 58 grass. Municipal waste contented the majority of plant materials and garbage and they should be sorted out daily and recycled as a fermented compost to improve soil fertility for better crop production and sustainable agriculture.
An Ecological Study on Earthworm (Pheretema sp.) in Different Environments of Nam Pong Soil Series (Ustoxic Quartzipsamment), Northeast Thailand
T. Chuasavathi,V. Trelo-ges,S. Ruaysoongnern
Pakistan Journal of Biological Sciences , 2000,
Abstract: A field survey was carried out on farmer land areas in Northeast Thailand where earthworms have been inhabited. Methodology being used was a grid method of 10x10 m plots in four different inhabitancies, i.e. native dipterocarp forest, tamarind orchard, natural grazing areas and sugarcane plantation. The results showed that earthworm inhabitants were largely found in soils with organic matter contents (OM %) ranging from 0.40-0.89% and soil pH values of the studied sites ranging from 4.68-6.29 whilst electrical conductivity (EC) values of soil locations were ranging from 52.9-94.0 μ Mho/cm. There were no clear trends on earthworm (Pheretema sp.) distribution have been recorded yet it seems more likely that organic matter, soil moisture contents, soil disturbances and seasonal changes had its effects on earthworm distribution. Variation in soil characteristics had no effect on earthworm distribution in Northeast Thailand and it was not considered as a limiting factor to proliferation of the earthworms.
Effect of Earthworm Activities (Pheretema sp.) on the Changes in Soil Chemical Properties at Different Soil Depths of Nampong Soil Series (Ustoxic Quartzipsamment) in Northeast Thailand
V. Trelo-ges,S. Ruaysoongnern,T. Chuasavathi
Pakistan Journal of Biological Sciences , 2002,
Abstract: This field research was carried out at Udon Thani Province, Northeast Thailand with the use of Nampong soil series (Ustoxic Quartzipsamment) during 1998 to investigate the effect of earthworm (Pheretema sp.) activities on the changes in chemical properties of Nampong soil series at different soil depths in different eco-systems. Soil samples were taken once at the soil depth of 0-10, 10-20, 20-30 cm from locations with and without earthworm activities of the four eco-systems for the determinations of EC, pH, OM, available P, exchangeable K, Ca, and Mg. The results showed that earthworm activities, in most cases, have improved soil chemical properties at different depths in all locations studied and it was found that soil electrical conductivity (EC), organic matter (OM), available phosphorous (P), exchangeable potassium (K), calcium (Ca) and magnesium (Mg) values of tamarind orchard farm were much greater than those of other studied sites both with and without earthworm activities.
Earthworm Casts (Pheretema sp.) Nutrient Contents of Nampong Soil Series (Ustoxic Quartzipsamment) in Northeast Thailand
T. Chuasavathi,V. Trelo-ges,S. Ruaysoongnern
Pakistan Journal of Biological Sciences , 2001,
Abstract: This earthworm cast experiment was carried out at four different sites of Nampong soil series (Ustoxic quartzipsamment) namely dipterocarp forest, tamarind orchard farm, grazing pasture, and sugarcane plantation. The results showed that earthworm casts of the four locations contented different levels of nutrients. The highest nutrient contents were found with Tamarind orchard farm followed by Dipterocarp forest, grazing pasture, and sugarcane plantation, respectively. Data on nutrient contents (NPK, Ca, Mg, and Na) of earthworm casts of each location were much higher than that of their respective soils. Earthworm casts could help to improve soil properties particularly Nampong soil series, which contented low level of soil fertility. This may help to improve crop yield for sustainable agriculture.
