Soil fertility decline is a big issue in the Agriculture of Ethiopia. The depletion of soil fertility is the main problem to sustain agricultural production and productivity in many countries. Soils in Ethiopian have low levels of plant nutrients due to their removal by erosion and leaching by high rainfall. One of the major constraints for crop production in Ethiopia is improper nutrient management. Organic fertilizer improves physical and biological activities of soil but they have comparatively low in nutrient content, so larger quantity is required for plant growth. However, inorganic fertilizer is usually immediately and fast containing all necessary nutrients that are directly accessible for plants, but the continuous use of inorganic fertilizers alone causes soil organic matter: degradation, soil acidity, and environmental pollution.
So the integrated nutrient management system is an alternative system for the sustainable and cost-effective management of soil fertility by combined apply of inorganic with organic materials resulting in rising soil fertility and productivity without affecting the environment. In this review the improvement of soil fertility and crops production (Girma Chala and Gebreyes Gurmu, 2018) Conducted an experiment on Organic and Inorganic Fertilizer Application and its Effect on Yield of Wheat and Soil Chemical Properties of Nitisols the research finding output at Holetta Agricultural Research Center in 2014 to 2015 these results of soil analysis after harvesting revealed that application of organic fertilizer improved soil pH, OC, total N and available P, the highest wheat grain and biomass yield (6698 kg/ha and 19417 kg/ha respectively) were obtained from the application of 50% VC and 50% N and P followed by full dose of recommended rate N and P from inorganic fertilizer resulting in 6241 kg/ha grain and 18917 kg/ha biomass yields respectively.
The objective of this review has assessed the effects of integrated organic and inorganic fertilizers on soil fertility and productivity. The study revealed that the appropriate application of organic with inorganic fertilizers increases productivity without negative effect on yield quality and improves soil fertility than the values obtained by organic or inorganic fertilizers separately.

- Sustainable soil management practices in Ethiopia
Chapter Summaries
1. INTRODUCTION: This introductory chapter sets the stage for the review by highlighting the widespread problem of soil fertility decline in Ethiopian agriculture. It emphasizes the critical need for sustainable soil management practices to ensure food security and agricultural productivity. The chapter likely introduces the concept of integrated nutrient management as a potential solution and lays the groundwork for a detailed examination of the effects of combining organic and inorganic fertilizers.
2. TO REVIEW THE EFFECT OF INTEGRATED USE OF ORGANIC AND INORGANIC FERTILIZERS: This chapter delves into the specifics of organic and inorganic fertilizers, exploring their individual advantages and disadvantages. It likely provides a comprehensive overview of various organic sources (such as manure, compost, and crop residues) and their nutrient content. Similarly, it discusses the characteristics and impact of inorganic fertilizers. The core of this chapter focuses on the integrated approach, examining the synergistic effects of combining organic and inorganic fertilizers on soil fertility and crop production. It likely presents experimental data from various studies to support the claims made regarding the effectiveness of integrated nutrient management. The chapter likely discusses the impact on different crops (maize, rice, wheat, tomato, teff) and their responses to different fertilizer combinations. Specific examples of experiments conducted and their results are likely included.
