Differences in the sediment composition of wind eroded sandy soils before and after fertilization with poultry manure

Wind erosion is known to be a gradual process of soil degradation on arable lands. Poultry manure fertilization common practice improve physical, chemical and biological properties, thus an essential part maintain fertility. Shortly after incorporation, poultry particles are loosely adjacent without any bonding. This supposedly affects the susceptibility soils wind influence physical composition wind-eroded sediment. tunnel experiments were conducted with three speeds (8, 11, 14 m s ?1 ) four sandy soils, each fertilized in rate 6 t ha . Incorporation changed particulate organic matter (POM) resulting increased median particle diameters, carbon contents hydrophobicity. caused preferred release already at close above threshold 7 greatest sorting effects size, shape, density particles. Thus, immediately leads losses added material. At higher sediment rather corresponds entire or soil-manure mixtures. Depending speed total loss, potential between 101 854 kg accounted, which 1.7–14% rate. The results indicate risk substantial loss redistribution by incorporation. • First study (wind tunnel) soils. Particle saltation fraction. Release was arise low (8 ). Preferred height transportation closely surface. Manure incorporation lead qualitative differences losses.
