IMPACT OF RICE CROP ON SOIL QUALITY AND FERTILITY
M. A. Talpur, J. I. Changying, S. A. Junejo, A. A. Tagar
Abstract: Soil fertility and quality play pivotal role in achieving the promising yield of the crops, which declines with intensive farming and it cannot last long unless managed properly. Maintenance of soil fertility is therefore very important for sustaining high paddy yields. This study was conducted to observe the impact of rice crop cultivation in paddy field. During these study physical, mechanical and chemical properties of soil at five different depths i.e. 0-15 cm, 15-30 cm, 30-45 cm, 45-60 cm and 60-75 cm before cultivation and after harvesting were tested. Results show that continuous shallow plowing a layer is formed at 31-45cm depth, while, the availability of nitrogen (N) decreases as availability of phosphorus (P) increased and little decrease in the availability of micro nutrients were observed. It was also observed that soil fertility has an indirect relation with depth in case of nitrogen and phosphorus.
