Soil Microbe Mediated Zinc Uptake in Soy Bean: A Review (Report‪)‬

INTRODUCTION Profitable cropping systems must be designed to realise a nutrient balance through continuous nutrient replenishment. Nutrients are replenished from parent rocks, processes of decomposition and mineralization of organic materials and atmospheric fixation by soil organisms. The process of soil formation is by weathering of underlying rocks through physical, chemical and predominantly by microorganisms and other soil biota through biological weathering processes [1]. Under natural conditions, the release rate of nutrients from minerals to soils and plants is not fast enough to provide nutrients for continuous annual crop production.
