Veris 3100 Application for Determining the Fertility of Rice Fields before Land Preparation

Abstract

Agriculture 4.0 demands the continuous development of technology and science in agriculture. Agriculture 4.0 applies the use of the latest technology to increase efficiency in agriculture both in terms of on-farm and off-farm. Provision of fertilizers and plant nutrients is an important factor in plant growth, but the fertilizer and nutrient needs of each block of the plant have different amounts depending on the condition of the soil condition and environment such as local climate. Generally physical and chemical measurements of soil done in laboratory which are laborious in sampling, takes a long time for analysis and costly. Nowadays there are some EC, PH, moisture sensor based on probe. However, this method cannot give results in real time also. Electrical conductivity of the soil (EC) has closed relation with physical and chemical properties of soil. Veris-3100 is one instrument that can measure EC for those purposes. This paper describes the correlation of measured EC by Veris-3100 and spot measurements of soil bulk density, cone index, pH and measured EC by probes.
