Abstract

Soil nutrients balance is an indicator to determine nutrient use efficiency in farming systems. For this purpose, the present study was conducted to assess nutrient use efficiency in different wheat farms in Gorgan. Collected data were included fertilization management such as type and amount of applied fertilizer in different farms. In respect to type of fertilizers applied in farm, amount of net NPK was calculated. Also, amount of supply of NPK was estimated by QUEFTS model which were 61, 34 and 136 kg/ha, respectively. In the end of the growth season, the concentration of these nutrients in plant was measured by tissue analysis and amount of exited nutrients (kg/ha) in each farm was estimated. The nutrients balance was calculated as the difference between entered (fertilizer and soil supply) and exited nutrients. The results showed that almost half of farms had deficiency of N application (negative balance). The amount of deficiency for N ranged from 2.5 to 124.4 kg/ha; while in others there was 1.3 to 128.3 kg/ha extra N (positive balance). The extra P and K were observed in nearly all farms that they were 10.9-79.3 and 11.5-115 kg/ha, respectively (positive balance).
