[ 1 ] - اثر اندازه خاکدانه بر قابلیت استفاده و جزء‌بندی فسفر در تعدادی از خاک‌های آهکی استان چهار محال و بختیاری

Understanding the distribution of different P forms in soil aggregate fractions is important in evaluating the risk of P run-off and leaching in the agricultural soils. The objective of the present research was to determine the effect of aggregate size on soil phosphorus availability and fractionation in 10 calcareous soils. Micro aggregate (< 0.25 mm), macro aggregate (> 0.25 mm) and whole soi...
