How can we minimize the nutrient losses from the agricultural field? Reducing the nutrient losses can increase the yield (in terms of Quality and Quantity) and Income for the farming community.

Drip irrigation system prevents nutrient loss from agricultural fields
Very pertinent question . If we are so good in analysis of soil samples and leaf samples , whatever the case may be, we are equally unprepared in interpretation of such test results. Nutrient losses or nutrient export from your field is only possible to be controlled , provided we have a prudent strategy to match the annual nutrient requirement versus what is annually removed by the crop or lost out of the feeding growing medium , unless that state of art strategy is developed , we will be repeatedly failing in addressing this important issue.
We have some great success in developing fertilizer recommendation based on STCR ,but yet not sufficient as new normal recommendation to be effectively adopted over such huge variation in soil type and land uses.We are more unprepared to address this issue in horticultural crops...
Conservation tillage techniques. Favouring conservation tillage or no-till would help reduce the loss of nutrients due to tillage. Conservation tillage also decreases the decomposition of residues and thus increases the available nitrogen for crops. https://ec.europa.eu/environment/water/water-nitrates/pdf/leaflets/Leaflet_Wielkopolskie_EN.pdf
Buffer strips of native grasses, plants, or turf reduce nitrogen and phosphorous in runoff water. Buffer areas receiving infrequent irrigation and fertilization provide a filter for nutrients from surface runoff water. The dense vegetation of a buffer slows runoff and allows time for water to infiltrate into the soil. https://www.usga.org/course-care/turfgrass-and-environmental-research/research-updates/seven-things-you-can-do-to-reduce-nutrient-loss.html
Farmers can reduce how often and how intensely the fields are tilled. Doing so can help to improve soil health, and reduce erosion, runoff and soil compaction, and therefore the chance of nutrients reaching waterways through runoff. https://www.epa.gov/nutrientpollution/sources-and-solutions-agriculture
