The impact of sugar beet (Beta vulgaris L.) harvesting on soil loss in high sugar beet-producing regions is not well understood. The objectives of this study were to (1) quantify soil loss due to sugar beet harvesting, (2) identify the potential factors influencing soil loss, and (3) estimate the cost of nutrients lost with soil due to sugar beet harvesting in northwestern Turkey. Sugar beet was harvested from three representative sites in northwestern Turkey. The amount of soil and nutrients lost as well as cost of nutrients lost was computed. Additionally, soil properties including water content, bulk density, particle-size distribution, and concentrations of organic matter, nutrients, and lime were measured at the time of sugar beet harvesting to study correlations with soil loss. The mean annual soil loss due to sugar beet harvesting was 1.63 Mg ha⁻¹ harvest⁻¹. The amount of nutrients lost with soil was 1.84 kg ha⁻¹ for N, 0.019 kg ha⁻¹ for P, and 0.91 kg ha⁻¹ for K. Soil water content, particle-size distribution, bulk density, lime, organic matter, and yield explained about 68% of the total variation in soil loss due to sugar beet harvesting. The estimated cost of nutrients lost with soil was $1.57 ha⁻¹ per sugar beet harvest. Results show that sugar beet harvesting causes significant losses of soil and nutrients in a high sugar beet-producing region in Turkey.

甜菜的影响（甜菜L.) 在高糖甜菜产区的土壤流失中收获还不是很清楚。本研究的目的是 (1) 量化甜菜收获造成的土壤流失，(2) 确定影响土壤流失的潜在因素，以及 (3) 估算土耳其西北部甜菜收获造成的土壤养分流失成本. 从土耳其西北部的三个代表性地点收获甜菜。计算了土壤和养分损失的数量以及损失的养分成本。此外，在收获甜菜时测量了土壤特性，包括含水量、容重、粒度分布以及有机质、养分和石灰的浓度，以研究与土壤流失的相关性。甜菜收获造成的年平均土壤流失量为 1.63 Mg ha ^-1收获^-1。营养物质与土壤损失的量是1.84千克公顷^-1为N，0.019公斤公顷^-1为P，和0.91公斤公顷^-1为K.土壤含水量，粒度分布，松密度，石灰，有机物质，和产量解释了由于甜菜收获导致的土壤流失总变化的 68%。每收获一次甜菜，土壤养分损失的估计成本为 1.57 公顷^-1美元。结果表明，在土耳其甜菜高产区，甜菜收获造成土壤和养分的显着损失。
