0 African Journal of Earth and Environmental Sciences Soil Fertility Assessment for Rice Cultivation in Sabuwa Area, Katsina State, Nigeria Musa Musawa Ahmed & Maharazu A. Yusuf Department of Geography, Bayero University, Kano. Kano State ABSTRACT Article History The study analyse the physical and chemical properties and assessed soil fertility for rice cultivation in Sabuwa area, Katsina State. Point-composite soil sampling methods for the Received: 19 February 2020 collection of soil samples between the depths of 0-20cm was adapted. The soil samples Received in revised form: 30 April 2020 were collected from sampled plots under rice cultivation and tested for some physical and Accepted: 15 May 2020 Published Online: 2 September 2020 chemical properties. The fertility was assessed by the comparing of soil properties and the requirements for rice. The result reveals that the soil properties including average clay of Keywords: 31.31%, pH of 4.56, P of 30.26ppm and K of 0.079cmol/kg were found under rice cultivation and are at low level compared to rice requirements. Some of the soil properties Soil Fertility, Rice, Sabuwa Corresponding Author Contact: were found to be at very low fertility level. These include AWHC, Oc, N, K, Ca, Mg and Musa Musawa Ahmed CEC. Analysis of variation (ANOVA) show that calculated value F (2.13) is less than Table value (12.89), that there is no variation among the samples. It can be concluded Email:
