A long-term investigation to under-stand soil fertility and scope of improvement in building-up of fertility and nutrient levels was carried-out adopting khejri based crop production site management approaches at ICAR-Central Institute for Arid Horticulture, Bikaner under hot arid agro-climate. A wide spectrum of varying land-use patterns (47 situation) were studied with or without khejri planting models (3, 6 and 9th years group) and for this virgin sand-dune landscape field was developed and studied for nutrient build-up and soil fertility characters over the period from 2004-2015 as innovative production site approach. The analyzed data of varying 47 situations under investigation depicted wide range for soil pH (8.27- 8.92), TDS (37 -130 ppm), EC (0.057 -0.203 ds/m), OC (0.068-0.100 %), N (72.73-107.76 kg/ha), P (8.11- 11.56 kg/ha), K (181.84-246.00 kg/ha) and S (3.50-8.27 kg/ha) and results exhibited that the approach is effective in improving the organic carbon and nutrient status in sandy soils. The treatment code KS-39 (KM-11, field of khejri plantation of nine years age-group with cluster bean cultivation) exhibited more effectiveness for soil fertility build-up in comparison to different land-use patterns. Based on 6 year age-group, treatment code KS-13 (KM-1, field of 4mx4m khejri plantation with three cluster bean crops during establishment period and normal field crop culture as organic plot) is found more effective for soil fertility build-up in comparison to other land-use patterns of the period. Among khejri models of three years age-group, treatment code KS-12 (KM-9, field of 24mx4mx4m plantation of 3 years of establishment with three rainfed cluster bean crop) depicted effectiveness for better soil fertility build-up. The analyzed data evidently demonstrated that virgin sand-dune land-scape developed as fields for crop cultivation under hot arid agro-climate can effectively be improved with khejri plantations and three crops of cluster bean for building-up of nutrients status, and it should be developed as systematic khejri based production sites for cultivation of diverse and resource based crop-commodities.
