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

Phosphorus (P) is an essential element for plants, deficiency and excess of P in soil will limit plant growth. It is required to applicate P fertilizer in appropriate dosage for promoting plant growth on the soil with different properties. The purpose of experiment was to study the respon of maize (Zea mays L.) for phosphorus fertilization on Regosol and Latosol soils. A glass house experiment was conducted to study maize response on P fertilizer application in Regosol and Latosol soils. The treatment 1was 0, 112, 336, 1008, 3024 and 9072 kg superfosfat ha . P fertilizer tend to increase the biomass of maize but exceed of P fertilizer reduced maize biomass. The optimum fertilization and vailability of P for plant affected by soil properties.
