The Effect of Organic Farming on Soil Properties and Crops in Agroecosystem (II)
The effect of organic farming on soil properties and crops in agroecsystem.Field trial was setting at Chishan, Kao-Hsiung county, form 1987 to 2004 to observe the effect of organic farming on the soil physical-chemical and biological properties, soil fertility and plant nutrients content. The test field including in an agroecosystem, the whole area of agroecosystem is 3.4ha, setting from 2001,and whole area use biological control method to manage the pest and weed instead of pesticides. The trial involved six treatments with the combination of three culture methods and two rotation sequence. Each treatment have no replication with plot size 0.1 ha. In this study, we sampling at harvest period, for measurement soil physical property, including soil bulk density, porosity and aggregate stabilities. Soil chemical and fertility, including soil pH, organic matter, available N, P, K, Ca, Mg, Cu and Zn, salinity, easy decomposition organic matter, and light fraction of organic matter.In otherwise, we determination of soil biomass nitrogen and soil biological activity. And N, P, K, Ca, Mg, Cu and Zn content of plant harvested protion, leaf with stem, and root. The aim of this study is to observe the organic farming of the probability of sustainable using soil.
