Abstract

Peatland has important role in wetland ecosystem stability. Depletion and disappearance of peat layer lead to loss of potential source of nutrient and disruption of wetland ecosystem stability. The research aimed to study the influence of peat thickness and land hydrological condition on the total nitrogen (N) content in soil, the influence of rapidly or naturally the depletion and disappear of peat layer on total N content in soil, and the influence of hydrological condition on total N content in soil. Total N was observed in June of 2009 and 2010 (transition from wet to dry season), September of 2009 and 2010 (peak of dry season), and January of 2010 and 2011 (peak of wet season). The research was carried out on potential acid sulphate soil (A), peaty acid sulphate soil (B),shallow peat which all of peat layers wereremoved (C), shallow peat which peat layer was partially removed (D), shallow peat (E), moderate peat (F) and deep peat (G). The results showed that total N content increased with increasing of peat thickness, the depletion and disappearance of peat layer reduced total N content in soil, and declining in the groundwater level increased total N content in soil.

Abstract

Nitrogen (N) and Phosphorus (P) are essential nutrients for plant.The deficiency one of these nutrients will be limiting the plant growth.A glass house experiment with one treatment factor was conducted to study the effect and interaction of N and P fertilizers application on maize growth in regosol and latosol soils. The results show that the interaction of N and P fertilizers application(N 1 P 1) on regosol had a significant influence to plant height on 3 to 7 weeks after planting, whilst on latosol had a significant influence to plant height on 1 to 5 weeks after planting. The shoot dry weight, root dry weight and total dry weight of maize on regosols and latosol soils were significantly influenced by the interaction of N and P fertilizers application (N 1 P 1). There were a positive correlation between N and P fertilizers application on both soils types to the total plant dry weight.

Abstract

The objective of the experiment was to investigate the effect of rice straw application on the growth of rice in two conditions of acid sulphate soils. An experiment was conducted in the glass house consisting of three treatment factors using the completely randomized design with three replications.The first factor was soil condition consisting of continuous application of rice straw and without application of rice straw during the last 5 years. The second factor was fresh application of rice straw consisting of application and without application, whereas the third factor was P application consisting of 3 rates of SP - 36 fertilizers.Parameters measured were plant height, tiller number and Fe toxicity score. Measurement were conducted at 2, 4, 6 and 8 weeks after planting. Plant dry weight and P concentration in plant tissue were determined at 8 weeks after planting. The result showed the main effect of rice straw application was significant decrease on the tiller number of the rice plant at 2, 4 and 6 weeks after planting, whereas significant on plant height was observed at 2 and 4 weeks after planting. Based on the scoring of degree of Fe toxicity, it was concluded that the rice plant did not exhibit any effect of Fe toxicity.
