**8. Conclusion**

Soil amendments could bring paradigm shift in oilseed production, by including as suitable strategies for maximizing crop productivity and optimize environmental sustainability. Poor soil fertility, salinity, sodicity, low soil organic matter, reduced bioavailability of sulfur and micronutrients etc. are some major constrain in oilseed production. Therefore, inclusion of soil amendments in management practices will improve soil productivity and crop yield. Organic manures, compost, biosolids, biochar, biofertilizers etc. are few organic amendments. Inorganic amendments such as gypsum, pyrite, lime, zeolite etc. are few inorganic amendments which are used for enhancing oilseed production. Soil organic amendments will supply both nutrients and organic matter providing more opportunities to enhance soil physical, chemical and biological properties. Inclusion of amendments such as carbon stable amendments like biochar, can improve soil properties and act as carbon reserve for longer time. Biofertilizers are the potential organic amendments that would improve nutrient cycling, enhance soil biodiversity, producing siderophores, organic acids, chelateswould enhance essential nutrient accumulation in crops. The positive impact of soil amendments depends upon their composition, types of materials, soil type, utilization, weather conditions, cropping system etc. However, soil amendments are valuable asset that meets the present circular economy paradigm approach. Comprehensive analysis of organic and inorganic soil amendments should be performed prior to application in oilseed crops, to determine the potential and limitations with respect to soil health and crop quality. Locally available soil amendments such as organic manures, compost, green manure, CR, biofertilizers etc. should be utilized for soil and crop productivity. Use of organic amendments can be a low input system which could help in achieving sustainability of agroecosystem. Soil amendments have the potential positive impact on various ecosystem services depending upon their composition, stability, origin, application rate and utilization, soil type, cropping sequence, weather parameters etc. Hence, comprehensive characterization or soil amendments in relation to different agroecosystem must be carried out before soil application, so as to identify the potentials and limitation of give soil amendments on soil health and crop quality.
